Hello, I am using an esp32c3 super mini board. I have some external stuff connected on pins 20 and 21... Unfortunately, it looks like there is some chatter there at boot time, and/or when I connect the esp to the USB... Is there a way to disable these other peripherals using these pins (what is usin...

Hello, Yes, it is for a stepper The 2 requirements are: - The pulses duration (both 0 and 1 parts) will need to vary over time (slow, at first, getting shorter, a steady phase (short) and a slow down). - I need to "program" an exact number of pulses A typical pulse sequence might have around 640000 ...

Hello, I'll be darned! I was certain that it was a dual core :-( Ok, back to planning. What is wrong with using the SPI to send a pulse which can be of variable size? They are 3 phases to any movements. Acceleration phase, regular speed and deceleration... With a SPI speed equal to 4 times my max sp...

Hello, ok, I have tried to pin my task to core 1... But this does not seem to work! I get a crash with the following error: xTaskCreatePinnedToCore(HWTask, "HWTask", 2048, nullptr, 2, nullptr, 1); << DOES NOT WORK xTaskCreatePinnedToCore(HWTask, "HWTask", 2048, nullptr, 2, nullptr, 0); << WORK!!! I ...

Hello, With regard to creating tasks pined to core... This is something that I know prety much nothing about. Could you help me, give me some pointers? As far as I understand the usual way to work on the esp32 is for core 0 to handle the "system stuff", which includes the wifi handling while core 1 ...

Hello, > You may want to stop the timer/alarm when&while pos==dst, which may significantly reduce system load. ok, easy, can do.... > Allocating the timer+interrupt on the APP CPU may also reduce interference with WiFi. Can you help me understand this? How would I do that? How do I know what is runn...

Hello, In my project, I need to toggle an IO pin at speeds up to 20khz, while the wifi is running... I have setup a 50µs clock using a GP timer (see code bellow), and in the IRQ routine, I will set/clear the pin as needed... However, adding this in my code make the Wifi unreliable.... The IRQ code i...

Hello, Which pins are used by the Wifi? At this point in time, I am using the Arduino Wifi example which does not interract with any HW (other than Wifi), so if there is a conflict, it is not due to me :-( Note that the exact same code, compiled with the exact same options, when sent to a ESP32C3 su...

Hello, I am using one of the ESP32C3 based boards with the build in 0.42" OLED display... ( https://fr.aliexpress.com/item/1005007448048350.html ) But I am unable to get any wifi working. Using the Arduino WiFiClient example, I am able to successfully connect using a "ESP32C3 super mini board" (a bo...

Hello,

Yes, it is an IRAM_ATTR function.

I tried adding: idf_build_set_property(COMPILE_OPTIONS "-mtext-section-literals" APPEND)
in mymakefile, But it did not work...


It first seemed to work.. But then it did not compile on 2nd test!

No clue why:-(
