there's no way to know which frame buffer is safe to draw to The order of the frame buffers to be flushed to the display is controlled by the user. Let's say you ask the driver to create 3 frame buffer and get them all in esp_lcd_rgb_panel_get_frame_buffer (fb0, fb1, fb2). By default, the LCD contr...

I would like to know when a write to MCPWM_TIMERx_PRESCALE get applied to the actual scaler New timer pre-scale value will take effect when the timer goes from STOP to START. new MCPWM_TIMER0_PERIOD < MCPWM_TIMER0_VALUE < current MCPWM_TIMER0_PERIOD Does it immediately jump to TEZ? or having alread...

Hi, recently we added a feature called "partial receive", which should fit your requirement. https://github.com/espressif/esp-idf/commit/106baac0bc14c17af055b2cdb9b2d7a2125d7384 (the feature only exists on the master branch) The idea is, to register a callback "on_recv_done", you can get notificatio...

New API available on the master branch now: https://github.com/espressif/esp-idf/co ... 2bfd341a70

We will backport that API to release/v5.0 and release/v5.1 as well.

Thanks for reporting. Yes, we will provide an API to change the period dynamically.

rmt_rx_memory_reset(RMT_CHANNEL_0) will reset the whole RMT FIFO memory. It should only be called for once in the initialization stage. Not sure what esp chips you're working with, ESP32S2? ESP32C3? But please note, ESP32-S2's RMT RX channel doesn't support ping-pong receive. The maximum RMT symbols...

We have the example for DShot protocol https://github.com/espressif/esp-idf/tr ... /dshot_esc

能描述一下你的应用为什么需要动态更改频率呢？

Thanks for reporting this. We will fix it ASAP!

Edit: Fixed for the master branch: https://github.com/espressif/esp-idf/co ... 9060d2b68e

Will backport the fix to 5.0 release soon.

Yes, moved to the component registry now, see the migration guide here: https://docs.espressif.com/projects/esp ... nents.html
