Re: ESP32 S3 video buffer filling

1. I noticed the third parameter in a callback function is user data: dma_callback(gdma_channel_handle_t dma_chan, gdma_event_data_t *event_data, void *user_data) how do I send this parameter? Setting a callback doesn't mention any parameters: gdma_tx_event_callbacks_t tx_cbs = { .on_trans_eof = dm...

Re: ESP32 S3 internal RAM test

There is not. It would A. be kinda tricky, as when your program is loaded, it already occupies some of the RAM, and B not really necessary as external RAM is mostly tested to catch issues with connection and signal integrity, which are not a problem with on-chip RAM.

Re: esp32s3 Cache and DMA

DMA doesn't have examples as DMA is not seen as a public API. You're supposed to use drivers, which will use DMA whenever it's relevant. Async memory copy API is public, but it's likely that it never got an example as it's a fairly trivial API, and the bits of code in the documentation should be eno...

Re: ESP32-C3FN4 12,13 GPIO

The pins are still connected to the flash, and putting random levels on these pins may still affect what the flash does.

Re: ESP32 S3 video buffer filling

It's not milliseconds, that's not what it is on any uC, it's microseconds at worst. For an EOF interrupt example, you could look at esp_lcd_panel_rgb in ESP-IDF, especially in bounce buffer mode it closely matches what you're trying to do.

Re: [ESP32C3] Application Not Running and Debugging Issues

There's only one log file attached to your post, so I can't see that log.

Re: ESP01 last firmware version for MQTT AT commands

You probably want to look at the repository where ESP-AT is maintained. Also, you seem to accidentally have had caps lock on while typing the title, I've taken the liberty to fix that.

Re: ESP32 S3 video buffer filling

I don't know Bitluni's code, but each DMA descriptor has an 'EOF' flag. You can set this flag; while it does not affect the data flow to the peripheral in any way, you can set up a DMA interrupt that triggers every time the DMA channel reads a descriptor with that flag set. You could use this to imp...
