@copilot please connect HSPI bus between U3 and BUCK_MODULE

copilot

Sure, let's connect the HSPI (SPI Host) bus between

U3

(ESP32-WROOM-32) and

BUCK\_MODULE

Here are the connections:

HSPI_CLK (Clock):
- Connect $U3:SCK/CLK$ to $BUCK\_MODULE:BUCK\_SPI\_CLK$ .
HSPI_MOSI (Master Out Slave In):
- Connect $U3:SDO/SD0$ to $BUCK\_MODULE:BUCK\_SPI\_COPI$ .
HSPI_MISO (Master In Slave Out):
- Connect $U3:SDI/SD1$ to $BUCK\_MODULE:BUCK\_SPI\_CIPO$ .
HSPI_CS (Chip Select):
- Connect $U3:SCS/CMD$ to $BUCK\_MODULE:BUCK\_SPI\_CS$ .

Additionally, ensure the following power and ground connections if not already made:

Connect $U3:VDD$ to an appropriate power supply like 3.3V.
Connect $BUCK\_MODULE:VIN$ to the input power source.
Connect $BUCK\_MODULE:GND$ to GND.
Ensure $U3:GND$ is connected to GND as well.

Would you like to proceed with these connections?

@copilot Please connect the HSPI bus on U3 to the SPI bus on BUCK_MODULE and power connection

copilot

Sure! I'll help you make the necessary connections between the HSPI bus on U3 (the ESP32-WROOM-32) and the SPI bus on the BUCK_MODULE which is likely part of U4 (the LD1117S33TR). Let's also handle the power connections.

Connection Details: HSPI to SPI Connection

HSPI CLK on U3 to SPI CLK on U4:
- Connect U3:20 (SCK/CLK) to U4:3 (BUCK_SPI_CLK)
HSPI MISO on U3 to SPI MISO on U4:
- Connect U3:22 (SDI/SD1) to U4:2 (BUCK_SPI_CIP0)
HSPI MOSI on U3 to SPI MOSI on U4:
- Connect U3:21 (SDO/SD0) to U4:4 (BUCK_SPI_COPI)
HSPI CS on U3 to SPI CS on U4:
- Connect U3:19 (SCS/CMD) to U4:5 (BUCK_SPI_CS)

Power Connection

3.3V Power to U3 and U4:
- Connect 3.3V:P1 to U3:2 (VDD)
- Connect 3.3V:P1 to U4:2 (OUT)
Ground Connections:
- Connect GND:P1 to U3:1 (GND)
- Connect GND:P1 to U4:1 (GND)

Summary of Connections

Connect U3:20 to U4:3.
Connect U3:22 to U4:2.
Connect U3:21 to U4:4.
Connect U3:19 to U4:5.
Connect 3.3V:P1 to U3:2.
Connect 3.3V:P1 to U4:2.
Connect GND:P1 to U3:1.
Connect GND:P1 to U4:1.

This should take care of the necessary SPI and power connections for your project. If you have any modifications or further details, please let me know!

@copilot how do i connect BUCK_MODULE and U3

copilot

To connect the BUCK_MODULE and $U3$ (ESP32-WROOM-32), we'll need to ensure that the power supply from the BUCK_MODULE provides a suitable 3.3V to $U3$'s VDD pin, and that the ground connections are common.

Assumptions:

The BUCK_MODULE is generating 3.3V.
$U3$ requires 3.3V on its VDD pin.

We'll perform the following connections:

Power Connections:
- Connect BUCK_MODULE:VOUT to $U3$:VDD.
Ground Connections:
- Connect BUCK_MODULE:GND to $U3$:GND.

Here is the detailed list:

Connect BUCK_MODULE:VOUT to $U3$:VDD.
Connect BUCK_MODULE:GND to $U3$:GND.

If you have any specific pins for the BUCK_MODULE, please provide that information to refine the connections.

Please connect the HSPI bus on U3 to the SPI bus on BUCK_MODULE and power connection

copilot

To connect the HSPI bus on the ESP32 ($U3$) to the SPI bus on the BUCK_MODULE, we'll align the necessary SPI signals (MOSI, MISO, SCK, and CS), and also ensure the power and ground connections are correct.

Here are the pin definitions we'll be using:

Table

$U3$ (ESP32)	BUCK_MODULE
HSPI_MOSI (IO13)	SPI_MOSI (BUCK_SPI_COPI)
HSPI_MISO (IO12)	SPI_MISO (BUCK_SPI_CIPO)
HSPI_SCK (IO14)	SPI_CLK (BUCK_SPI_CLK)
HSPI_CS (IO15)	SPI_CS (BUCK_SPI_CS)
VDD (3.3V)	VIN (VIN)
GND (GND)	GND (GND)

Detailed Connections

Power Connections:
- Connect 3.3V:3V3 to BUCK_MODULE:VIN.
- Connect GND:GND to BUCK_MODULE:GND.
HSPI Connections:
- Connect $U3$:IO13 to BUCK_MODULE:BUCK_SPI_COPI.
- Connect $U3$:IO12 to BUCK_MODULE:BUCK_SPI_CIPO.
- Connect $U3$:IO14 to BUCK_MODULE:BUCK_SPI_CLK.
- Connect $U3$:IO15 to BUCK_MODULE:BUCK_SPI_CS.

Connections List

Connect 3.3V:P1 to BUCK_MODULE:VIN.
Connect GND:P1 to BUCK_MODULE:GND.
Connect $U3$:IO13 to BUCK_MODULE:BUCK_SPI_COPI.
Connect $U3$:IO12 to BUCK_MODULE:BUCK_SPI_CIPO.
Connect $U3$:IO14 to BUCK_MODULE:BUCK_SPI_CLK.
Connect $U3$:IO15 to BUCK_MODULE:BUCK_SPI_CS.

Make sure you verify the configuration aligns with the required operating conditions of the BUCK_MODULE and $U3$ (ESP32-WROOM-32).
