Waveshare ESP32 P4

[ITstreet1]

I just noticed that Waveshare made a few P4 boards that look promising.

I wonder if this could be programmed by just selecting the ESP32-P4 board?

If they used the same pins for the C6 WiFi module, then yes. Custom pin selection will come in 3.3.0

Thank you. I missed that.

Hi,

I ordered Waveshare ESP32-P4-Module-DEV-KIT in which ESP32-P4 extends its WIFI functionality by connecting to an ESP32-C6 module via SDIO (ESP32-C6 acts as a slave for ESP32-P4 as host).

Could you please advise (or share a piece of Arduino IDE code) how to program this combo to connect to and use WiFi?

For VSCode they say to add two components to make things done (https://www.waveshare.com/wiki/ESP32-P4-Module-DEV-KIT-StartPage#WIFI_Networking_Demo):

// In a WIFI project, add the following two components through the ESP-IDF component management tool
idf.py add-dependency "espressif/esp_wifi_remote"
idf.py add-dependency "espressif/esp_hosted"

PS. I am on ver. 3.3.0-Alpha1

Not easy. Needs custom board definition to specify the pins used for the C6. You can have a look at the one for our P4 board

Do you mean this definition in ...\Arduino15\packages\esp32\hardware\esp32\3.3.0-alpha1\variants\esp32p4\pins_arduino.h ?

//WIFI - ESP32C6
#define BOARD_HAS_SDIO_ESP_HOSTED
#define BOARD_SDIO_ESP_HOSTED_CLK   18
#define BOARD_SDIO_ESP_HOSTED_CMD   19
#define BOARD_SDIO_ESP_HOSTED_D0    14
#define BOARD_SDIO_ESP_HOSTED_D1    15
#define BOARD_SDIO_ESP_HOSTED_D2    16
#define BOARD_SDIO_ESP_HOSTED_D3    17
#define BOARD_SDIO_ESP_HOSTED_RESET 54

No additional libraries are needed?

[me-no-dev]

yes, but keep in mind this will be overwritten next time you install new core
