Re: Using esp-idf framework for ESP8266?

I tried solving this by (trying to ?) disabling all irq's, which improves things. But still timing tends to be off sometimes.
Details and issue here: https://github.com/espressif/ESP8266_RT ... issues/680 :)

Re: RMT based NeoPixels (WS2812B) flickers when WiFi is used

Hi! I don't know if it will help, but be mindful that with this line: xTaskCreate(rainbow, "ws2812 rainbow demo", 4096, NULL, 10, NULL); The rainbow task might still run on any/either core. So I'd recommend using: xTaskCreatePinnedToCore(rainbow, "ws2812 rainbow demo", 4096, NULL, 10, NULL, 1); inst...

Re: flash-programming using rfc2217

[quote=kolban post_id=14184 time=1505616872 user_id=105] I think we can "chain" a solution together to do this with sftp, ssh, node.js or a variety of other tools without wandering into "old fashioned" (opinion) telnet based stories.

Re: flash-programming using rfc2217

This works for me using rfc2217_server.py, with some caveats: - The latest version of esptool that works is 2.4.1, after that they set a timeout, which is not supported by the python rfc2217 client library used. - Actually getting the board in flash mode does not work, so I manually need to press th...

Re: RMT based NeoPixels (WS2812B) flickers when WiFi is used

Right, I think I actually fixed my problem.. I created the interrupt handler (rmt_driver_install for RMT, digitalLeds_initStrands for the WS2812 library) from the main task (app_main), which apparently defaults to being on core 0. This also makes the interrupt handler being handled on core 0 (as doc...

Re: RMT based NeoPixels (WS2812B) flickers when WiFi is used

Did this ever get resolved? I see the same issue, when sending MQTT, starting the sending just before, or during sending of RMT sequence (to drive ws2812 leds). Waiting while sending the RMT sequence (e.g. rmt_write_items(..,..,..,..,wait =TRUE)) and then sending MQTT after shows no issues, so it se...
