Simple blink example for RGB Led on Esp32 C6 #384

Closed franxois closed 6 months ago

franxois commented 9 months ago

Hi,

I try to use the rmt_neopixel example on my esp32-c6 board with onboard rgb led but it doesn't work. My board is a nanoESP32-C6 (clone?). I only change gpio2 to 8 but the led don't blink.

On the other hand, the example on https://github.com/espressif/esp-idf/tree/release/v5.2/examples/get-started/blink/main works out of the box.

I also tried with the blinky example, I notice a diff with the gpio8 init in the monitor log : working : gpio: GPIO[8]| InputEn: 0| OutputEn: 1| OpenDrain: 0| Pullup: 1| Pulldown: 0| Intr:0 non working : gpio: GPIO[8]| InputEn: 0| OutputEn: 0| OpenDrain: 0| Pullup: 0| Pulldown: 0| Intr:0

How to achieve the same init in the blinky.rs code ? Is there another thing I should change to make the led blink in rust ?

I choosed to not reopen the similar issue https://github.com/esp-rs/esp-idf-hal/issues/249

I had the same problem as @franxois here... but after building with a version that has #402 in it, the problem went away! So I'm pretty sure this can be closed now that #402 is in.

(Oh, although I might be misunderstanding the OP here: I was trying to use the RMT on the RGB LED on the stock espressif ESP32c6 dev kit. The "blinky" example is not relevant to that because blink is only for single-color LEDs that are tied directly to the GPIO. But @franxois, if you indeed meant you're trying to get a ws2812-style RGB-LED working, then it makes sense that rmt_neopixel was broken, but now has nbeen fixed due to #402)

Both classical blinky and RGB Leds should work on any boards with the current master branch. If its still doesn't work for OP please reopen it with a short code snippet of what you are doing.

Hello, thx for the update.

I confirm that the rmt_neopixel example works now on my board
