Arduino_DMXWirte example compilation error

[Jibeji]

Hi,
Trying to get the example working on an ESP32 Dev Module board with Arduino IDE 1.8.9 and the latest Espressif definitions, I have this error:

C:\Users\JB\Documents\Arduino\libraries\esp_dmx\src\dmx\hal\uart.c: In function 'dmx_uart_init': C:\Users\JB\Documents\Arduino\libraries\esp_dmx\src\dmx\hal\uart.c:330:51: error: 'uart_signal_conn_t' has no member named 'module' 330 | periph_module_enable(uart_periph_signal[dmx_num].module);

Same issue here. It seems going to esp32 3.0.4 in boards manager and 4.0.0 of this library makes the error disappear. But I haven't checked that it actually works properly yet as I don't have my scope handy.

What a royal pain! I also ran into this problem and of course, natually assumed that it was caused by problems with my code or how the compiler was set up.

I rolled the ESP32 Core back to 3.0.4 but left the ESP_DMX library at 4.1.0. Yes, it does compile and work, at least it did for me.

Gave it a run up with 4.1.0 of this library myself and confirm this combo works here too.

Rolling back the esp32 BM version is a better idea than patching this library, unless your usecase uses IDF functionality in later versions of the esp32 boards library.

As soon as you start patching libraries you risk losing your patches in a future upgrade, and you will then have to keep re-patching until it is fixed.
