Derf jagged I've got the same requirement to allocate one core to a continuously looping task. Please could you share the code you used to create the critical task and lock it to a CPU Many thanks Sorry for the extremely late reply, I just dug this up in my open tabs. Hopefully this might help you ...

Thanks for the reply. Looking through the pages you linked (and some pages linked there), the regular wireless protocol is a bit different from the Bluetooth one; the Bluetooth one doesn't have a counter for instance and the duplicate events may be Bluetooth only. The esp_hid_host sample filters out...

Still haven't found a solution for this.

Hello! I have connected my Xbox One S controller to the ESP32 via Bluetooth and can see and parse button press and release events. However, it looks like every time I press a button on the controller, it fires three events instead of just one, and occasionally one of the three events is completely d...

In the end, after experimenting a lot with vTaskEndScheduler() and others, I found that just spawning my critical task on cpu1 and calling portENTER_CRITICAL() at the start worked so long as I turned off the Task Watchdog for cpu1. Works great, I can do GPIO manipulation in an infinite loop.

While I look into that, do you know any of the answers for the questions in the first post? It's so close to working perfectly!

You can possibly adjust the I2S parallel (LCD) mode to do that. There's no real driver in ESP-IDF for that though, although there are a fair few projects that use that mode out there. In general, what are you trying to do; what are you writing to? Hmm, I'll look into that.. My project is emulating ...

General advice: Don't bitbang GPIOs on the ESP32. The FreeRTOS tick timer isn't the only thing leading to jitter there: shared buses, RPC calls because of flashing etc, they can all influence timing. Rather, try to see if there's a hardware device that can generate the signal you need. For instance...

I have a task running on the second core that flips GPIOs on and off and takes between 900ns and 1500ns about 4 times per second. Unfortunately, the FreeRTOS scheduler preempts this task every 1ms and causes a large delay and making it take too long. Is there a way that I can either: - Disable the F...

Well, after some hours during last days studying, setting up esp-idf and using code from Mr. Weber Github repo, It seems that it works. It starts core 0 normally, and set a task to run only on core 1, it ius running an endless testing loop that does a frequency sweep on a GPIO out, I wired it up to...
