I was trying to use a RMT sync manager on the ESP32-D0WD-V3 (Version 3.1). However, trying to use rmt_new_sync_manager() returns ESP_ERR_NOT_SUPPORTED with the following message:
␛[0;31mE (560) rmt: rmt_new_sync_manager(331): sync manager not supported␛[0m ESP_ERROR_CHECK failed: esp_err_t 0x106 (ESP_ERR_NOT_SUPPORTED) at 0x400d2681
This leads me to believe that the ESP32-D0WD-V3 does not support any RMT sync managers. So far, I have not tried with other controllers.
