copilot

To create a schematic diagram connecting the components you've listed, we'll start by defining how each component should be connected for basic operation and communication. Since you're working with a setup that includes a CAN bus, a temperature sensor (NTC Thermistor), and programming/debugging interfaces, I'll outline the connections accordingly.

Basic Connections 1. STM32F103C8T6 Blue Pill to MCP2551 CAN Transceiver

Since you have two sets of these for a CAN communication setup, let's connect them accordingly:

Blue Pill 1 and MCP2551 1:
- Connect Blue Pill 1 (TX) to MCP2551 1 TXD
- Connect Blue Pill 1 (RX) to MCP2551 1 RXD
- Connect both GNDs together
- VCC of MCP2551 to 5V output of Blue Pill
Blue Pill 2 and MCP2551 2:
- Same as the first set, replacing "1" with "2" in designators.

2. CAN H and CAN L between MCP2551 Breakout Boards

Connect MCP2551 1 CANH to MCP2551 2 CANH
Connect MCP2551 1 CANL to MCP2551 2 CANL

This creates the physical bus for CAN communication.

3. STLink v2 debugger to Blue Pill

This connection is for programming/debugging purposes:
- Connect STLink SWDIO to Blue Pill SWDIO
- Connect STLink SWCLK to Blue Pill SWCLK
- Connect GND to GND

4. USB to Serial Converter to Blue Pill

Use this for UART communication/debugging purposes:
- Connect USB to Serial Converter TX to Blue Pill A9 (RX)
- Connect USB to Serial Converter RX to Blue Pill A10 (TX)
- Connect GNDs together

5. NTC Thermistor Connection

NTC Thermistors require a resistor in series or parallel for a voltage divider configuration, which allows the STM32's ADC to read temperature variations. Assuming the use of a 10kΩ thermistor and a 10kΩ resistor for simplicity:

Connect one side of the NTC Thermistor to 3.3V on the Blue Pill.
Connect the other side of the NTC Thermistor to one side of a 10kΩ resistor.
Connect the other side of the 10kΩ resistor to GND on the Blue Pill.
Connect the junction between the NTC Thermistor and the 10kΩ resistor to an analog pin on the Blue Pill, say A0, for temperature reading.

Additional Connections

All VCC and GND pins of the Blue Pills should be connected to your power source appropriately (3.3V for VCC, GND to ground).
Ensure decoupling capacitors (typically 100nF) are placed close to the VCC and GND pins of your STM32F103C8T6 microcontrollers and MCP2551 transceivers.

This configuration provides a basic outline for connecting these components together. Depending on your exact requirements, there may be additional connections or specific pin configurations, especially for the STM32F103C8T6 Blue Pill boards, which have multiple functionalities per pin.

Please adjust the pin designations based on your specific setup and requirements. If you need further clarification or help designing a specific part of your circuit, feel free to ask!

I need help in designating the pins to connect

copilot

Certainly! To assign specific pins and ensure proper connections between your components for the CAN communication setup, programming, and temperature sensing, let's dive into more detailed pin assignments using typical configurations for each component. Since explicit pin numbers or designations weren't provided, I'll use common ones for these components. Adjustments might be needed based on your exact module versions or specific requirements.

STM32F103C8T6 (Blue Pill) Pin Designations:

For the Blue Pill boards, we'll use its standard pinout. Here are more detailed connections:

1. Connecting STM32F103C8T6 to MCP2551 CAN Transceiver:

For CAN communication on Blue Pill, commonly PA11 (CAN_RX) and PA12 (CAN_TX) are used.

Given that, for both Blue Pill boards connecting to their respective MCP2551:

Blue Pill 1 to MCP2551 1:
- Connect Blue Pill 1 PA12 (CAN_TX) to MCP2551 1 TXD
- Connect Blue Pill 1 PA11 (CAN_RX) to MCP2551 1 RXD
Blue Pill 2 to MCP2551 2:
- Connect Blue Pill 2 PA12 (CAN_TX) to MCP2551 2 TXD
- Connect Blue Pill 2 PA11 (CAN_RX) to MCP2551 2 RXD

And for power connections:

Connect MCP2551 VCC to Blue Pill 5V (via a voltage regulator if your MCP2551 requires 5V).
Connect all GNDs together.

2. Connecting MCP2551 CAN Transceivers for CAN Bus:

Connect MCP2551 1 CANH to MCP2551 2 CANH, and MCP2551 1 CANL to MCP2551 2 CANL.

3. Connecting STLink v2 debugger to a Blue Pill:

Connect STLink SWDIO to Blue Pill's Pin PA13 (SWDIO)
Connect STLink SWCLK to Blue Pill's Pin PA14 (SWCLK)
Connect a GND pin from STLink to GND on the Blue Pill

4. USB to Serial Converter to Blue Pill Connection:

Connect USB to Serial Converter TX to Blue Pill PA10 (USART1_RX)
Connect USB to Serial Converter RX to Blue Pill PA9 (USART1_TX)
GND from the converter to GND on the Blue Pill

5. Connecting the NTC Thermistor:

For measuring temperature:

Connect one side of the NTC Thermistor to Blue Pill's 3.3V.
Connect the other side of the NTC to one side of a 10kΩ resistor (R1).
Connect the other side of the resistor (R1) to GND.
Connect the junction between the NTC Thermistor and R1 (voltage divider output) to Blue Pill PA0 (ADC_IN0).

Notes:

Decoupling capacitors: Place a 100nF capacitor close to the power pins of each STM32F103C8T6 and MCP2551 as a good practice for stability.
Power Supply: Ensure your power supply to the Blue Pills is stable and capable of providing necessary current. The Blue Pill boards typically operate at 3.3V but can tolerate 5V on some pins; MCP2551 may need a 5V supply, so plan your power routing accordingly.
Additional functionality: If you're using other functionalities (e.g., additional sensors, interfaces), ensure that pin assignments do not conflict with those functionalities.

This setup should get you started on connecting your components within Flux for a CAN communication setup, programming, and temperature reading. If you have specific requirements or need to adjust pin assignments based on your application, feel free to provide more details!

To provide you with accurate advice on how to connect the components you've listed, I'll need you to share the list of components in your project. Could you please provide the details of the components including their designators (e.g., IC1 for an integrated circuit, R1 for a resistor, etc.) and any specific details about their connections or roles within the circuit? This information is crucial to ensure clear communication and assist effectively with your schematic design.

@copilot create a schematic diagram using the description of this project

copilot

To create a schematic diagram based on the description of your project, I'll need a few more specific details from you. However, I can guide you on the general steps to take and things to consider based on the standard process of creating a schematic in electronic design. Assuming we're using Flux for this design process, here are the steps and considerations you should follow:

Identify Components and Their Symbols:
- Begin by listing out all the components you will be using in your project. This includes resistors, capacitors, transistors, integrated circuits (ICs), and any other elements your circuit may need.
- For each component, you'll use a standardized symbol that represents it on the schematic. These symbols are essential for communicating your design effectively to anyone who reads the schematic.
Outline the Project's Functionality:
- Have a clear understanding of what your project is intended to do. This can help in organizing the schematic in a logical manner that reflects the system's functionality.
Draw the Schematic Diagram:
- Place each component symbol on the schematic canvas. Position them in a way that logically represents your circuit’s flow and functionality.
- Use lines to represent electrical connections $nets$ between the symbols. These connections are crucial as they dictate how the current flows through your circuit.
Assign Net Names and Component Designators:
- Each component should be labeled with a unique designator $e.g., R1 for the first resistor, C1 for the first capacitor$ .
- Assign names to important nets in your circuit. This helps in identifying connections, especially when the same connection reappears in different parts of the schematic.
Review and Revise Your Diagram:
- Once you have all the components placed and connected, review your schematic to ensure all connections make sense and accurately represent your intended circuit design.
- Look for common schematic errors, such as accidental shorts, missing connections, or logical errors in the circuit.
Generate the Netlist:
- After finalizing your schematic, you will need to generate a netlist. This is a report detailing every electrical connection in your design, which will be used later in the PCB layout process.

Can you provide me with more details regarding the components, functionality, and any specific requirements of your project? With that information, I can offer more detailed advice on how to proceed with your schematic design in Flux.

Dashed arrows (-.->) signify programming or debugging connections that do not form part of the operational data flows in your project's application.

Notes:

U1 and U2 are both STM32F103C8T6 microcontrollers by STMicroelectronics. U1 is designated as the master microcontroller, with U2 functioning as the slave in your design.
U9, the MCP9808T-E/MC temperature sensor by Microchip Technology, is connected to the slave microcontroller (U2) via I2C for temperature measurements.
The CAN communication between U1 (Master MCU) and U2 (Slave MCU) is facilitated through MCP2515 CAN Controllers (U3 and U4) by Microchip Technology.
U5, the STLINK-V3MODS also from STMicroelectronics, is used for programming and debugging purposes with both U1 and U2.

This representation is intended to provide a visual overview of the key components and their interactions within your project, based on the textual description provided and assuming some typical connections, such as CAN and I2C communication and the use of a debugger/programmer.

which pin is CANH and CANL

vivek44

@copilot which pin is CANH and CANL

copilot

In your project description, the CANH and CANL pins are not explicitly mentioned, as the MCP2515 CAN controller chips used (U3 and U4) interface with the CAN network through an external transceiver, typically the MCP2551 or a similar IC, which physically handles the CANH (High) and CANL (Low) connections to the CAN bus.

The MCP2515 itself doesn't have direct CANH and CANL pins because it interfaces with the CAN network digitally through its TXCAN and RXCAN pins:

TXCAN (Transmit CAN): This is the output from the MCP2515 to the transceiver, where it sends out data to be transmitted on the CAN network. This pin would connect to the TX input of a CAN transceiver.
RXCAN (Receive CAN): This is the input to the MCP2515 from the transceiver, where it receives data from the CAN network. This pin would connect to the RX output of a CAN transceiver.

For a typical CAN transceiver like the MCP2551, which you mentioned with your MCP2551 CAN modules, the CANH and CANL pins are part of the physical layer handling differential signaling over the CAN network:

CANH (High): This is the high side of the differential pair used in CAN communication.
CANL (Low): This is the low side of the differential pair.

Since these details are abstracted out in your project description, assuming you are using MCP2551 or a similar CAN transceiver, here would be the typical connections:

MCP2515 (U3 or U4):TXCAN to CAN Transceiver TX Input
MCP2515 (U3 or U4):RXCAN to CAN Transceiver RX Output
CAN Transceiver:CANH and CAN Transceiver:CANL would then connect to the CAN network.

However, as these connections to CANH and CANL are assumed to be through an unlisted CAN transceiver component in your project, please ensure appropriate connections if using a different model or verify with the specific datasheet of your CAN transceiver.
