rmt_transmit(tx_channels[0], copy_encoder, your_raw_rmt_symbols, sizeof (your_raw_rmt_symbols), &tx_config)


Seems like you want to transmit "items", not "your_raw_rmt_symbols", here.


Thanks for reply.
It was the typo.
I am transmiting "items".
And the result remains the same.

Hi
I am trying to use RMT to generate signal.
Below is my code:
void RMT1 () {
rmt_channel_handle_t tx_channels[2] = {NULL};
int tx_gpio_number[2] = {4, 4};

rmt_copy_encoder_config_t copy_config = {};
rmt_encoder_handle_t copy_encoder = NULL;
ESP_ERROR_CHECK(rmt_new_copy_encoder(&copy_config ...
