@copilot Check that all reset/enable have an external pull-up or pull-down resistors. Report action items in an ordered list.

To check if all reset/enable signals have required pull-up or pull-down resistors, let's review the project components and nets.
  1. U3 - ESP32-WROOM-32: This component has an enable pin labeled as 'EN'. According to the datasheet of ESP32-WROOM-32, an RC delay circuit is usually recommended at the EN pin. Typically, the resistor value is (10 , k\Omega) and the capacitance value is (1 , \mu F). These values may need to be adjusted depending on the exact power-up timing requirements of your specific application[1].
  2. Examining the project nets, there's a net named 'RESET' that appears to be associated with the EN pin of U3. However, there's no clear information if there's an external resistor connected to this net.
Based on these observations, here are the action items:
  1. Check the connections of the 'EN' pin of U3. Ensure it's connected to an RC delay circuit as recommended in the ESP32-WROOM-32 datasheet.
  2. Find and check the functionality of the 'RESET' net. If it's connected to an enable or reset pins of components, ensure that it has the necessary pull-up or pull-down resistors.
  3. For every component in the project that has a reset or enable pin, ensure that it is connected to an appropriate net and has an external pull-up or pull-down resistor if necessary. Reference the specific component datasheets for direction on this.

@copilot please connect the HSPI bus on U3 to the SPI bus on BUCK_MODULE

To connect the HSPI bus on ESP32 (U3) to the SPI bus on the BUCK_MODULE, you can connect the following pins:
  1. Connect U3:IO13/HSPI_COPI to BUCK_MODULE:BUCK_SPI_COPI
  2. Connect U3:IO12/HSPI_CIPO to BUCK_MODULE:BUCK_SPI_CIPO
  3. Connect U3:IO14/HSPI_CLK to BUCK_MODULE:BUCK_SPI_CLK
  4. Connect U3:IO15/HSPI_CS0 to BUCK_MODULE:BUCK_SPI_CS
Please note that this is assuming the BUCK_MODULE supports SPI and is compatible with the locations of the HSPI pins of the ESP32. If your BUCK_MODULE uses a different naming scheme for SPI pins, you'll need to adapt this accordingly.
Here's what each connection does:
  • COPI (Controller Out-Peripheral In), also known as MOSI (Master Out-Slave In), sends data from the ESP32 to the BUCK_MODULE.
  • CIPO (Controller In-Peripheral Out), also known as MISO (Master In-Slave Out), sends data from the BUCK_MODULE to the ESP32.
  • CLK is the clock signal for synchronizing data transfer.
  • CS is the Chip Select, or Slave Select, which enables communication with the BUCK_MODULE when pulled low.
Remember, communication protocols like SPI can vary across different devices, so ensure to check your specific BUCK_MODULE datasheet to verify the correct connections.
