SPI bus configuration fails on ESP32S2 devices

[rosterloh]

The problem

While trying to configure a SPI bus on an ESP32S2 using the Arduino framework the build fails due to VSPI not being defined for this platform. For ESP32S2 and ESP32S3 FSPI needs to be used

Which version of ESPHome has the issue?

2022.6.2

What type of installation are you using?

Docker

Which version of Home Assistant has the issue?

N/A

What platform are you using?

ESP32

Board

um_feathers2

Component causing the issue

SPI

Example YAML snippet

esphome:
  name: spi-example

esp32:
  board: um_feathers2
  variant: esp32s2
  framework:
    type: arduino
    version: 2.0.3
    platform_version: 5.0.0

spi:
  clk_pin: GPIO36
  mosi_pin: GPIO35
  miso_pin: GPIO37

Anything in the logs that might be useful for us?

Hi, this is already an known issue. Somehow the VSPI define is not defined under ESP32-c3 and it seems now that it does not for the esp32-s2 as well.

on my github page at https://github.com/nielsnl68/switchplate i have added a temporary fix for it.

you can load it by adding:

external_components:
  - source: github://nielsnl68/SwitchPlate
    components: [ spi ]

the only thing it does is replacing VSPI with 3. And that seems to work.

I can't get the above to work on a T-Display S3 with an esp32s3. It say's spi component not found. Here's my current config

esphome:
  name: s3

spi:
  clk_pin: GPIO12
  mosi_pin: GPIO11

esp32:
  board: esp32-s3-devkitc-1
  variant: esp32s3
  framework:
    type: arduino
    version: 2.0.4
    platform_version: 5.1.1

The ESP32-C3, like the ESP32-S3, does not have a dedicated VSPI peripheral. Instead, it has two general-purpose SPI peripherals, SPI2 and SPI3.

Suggestion: Update VSPI code to use SPI2_HOST or SPI3_HOST.
