Edit: Got it figured! Short answer; the complete definition of the callback configuration structure is: typedef struct { rmt_encode_simple_cb_t callback; /*!< Callback to call for encoding data into RMT items */ void *arg; /*!< Opaque user-supplied argument for callback */ size_t min_chunk_size; /*!...

Well all righty then! I will certainly give that a shot. Very much appreciated.

Thanks for the reply. Yes, I did check out the simple encoder though it seems that with that, options like DMA, setting the GPIO pin as open drain, etc. cannot be used as it doesn't take a user defined `rmt_tx_channel_config_t` structure. Mind, I can't find where a default structure (if any) is defi...

Hi all.

Is there a way when using the HTTPClient library to dump to the serial monitor the: actual data sent to a host via a GET raw data received in response to a GET before it is handled by the HTTPClient library? Setting the Core Debug Level to "Verbose" kind of does the second item but it is sent during...

When powered up, the ESP sends a bunch of information out to the USB port via UART0, which is connected to the Serial/USB bridge chip. On this particular board, the designers chose to put an LED on the TXD line of UART0, I suppose to let the user know when the ESP32 is sending data. This was confirm...

Thank-you for the awesome answer. Very much appreciated. Have a great one .

Can anyone explain, for the RMT peripheral, what the function:

rmt_translator_set_context()

does?

1. It is needed to transmit data using the RMT controller?
2. How does it interact with the other RMT functions and structures?

Many thanks.

Seeking clarification on which GPIO pins to use for CS lines when multiple devices are connected to an SPI bus using the SPI Master driver. From this page in the docs: https://docs.espressif.com/projects/esp-idf/en/v3.3.6/api-reference/peripherals/spi_master.html#_CPPv417spi_host_device_t It states:...
