Hello! I am currently working on sdio logging on SD card with esp32s3. I'm using platformio with : - platform = espressif32 @ 6.6.0 - framework-arduinoespressif32 @ 3.20014.231204 (2.0.14) - toolchain-xtensa-esp32s3 @ 8.4.0+2021r2-patch5 My system uses 2 buffers and one task per core for logging pur...

@idahowalker : thanks for your answer! I did that and confirm that these two lines are the cause of my pb ^^: SerialSBUS.end(); delay(10); SerialSBUS.begin(BaudRate, SERIAL_8E1, RX_Pin, TX_Pin); delay(10); I can not explain why but this is causing the wdt error if repeated, even with the delays. I n...

Hello, I ran addr2line with the firmware.elf file: xtensa-esp32-elf-addr2line -pfiaC -e firmware.elf 0x4008134c It returned: 0x4008134c: _uart_isr at esp32-hal-uart.c:? I think the problem is coming from this portion of code (because of "out of sync" uart buffer phenomenon that appears in some situa...

Hello, I'm facing this problem that happens sometimes in a no repeatable way :? . I use platformIO with arduino framework to write code for the esp32 and I am using the 2 cores. This problem occurs on CPU0 only, here is the backtrace: Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on ...

Hello,

just to give an answer if someone is facing the same problem with timerRead:

-Use timer_get_counter_value instead of timerRead, it works perfectly!

Hello, I tried to use built in 64 bits hardware timers to measure pulse width inside interrupts using following method: Pseudo code: timer = timerBegin(0, 80, true); attach interrupt RISING; rising_interrupt() { t_now = timerRead(timer); attach interrupt FALLING; } falling_interrupt() { Pulse_Width ...

Hello, thx again for your answer ESP_igrr, I tried the loop mode, it now works a lot better without the 144ms delay and with a correct delay of 6us between frames which is excellent. This is exacttly what I need for my use! I've got only one problem remaining: -With random frequency, frames longer t...

Hello, I used RMT to generate the signal and the result is strange: -Signal frames are generated precisly and correctly -> Good :D -Unexplicable 35us delay between frames -> Not good :shock: -Huge delay of 140 ms that seems like a reset or something like that... -> Not good at all :oops: Here is the...

Hi ESP_igrr,

thx for your reply! It looks like a great feature that I didn't know... perhaps because of its name^^. I'll try too investigate this way!

Hello everyone, I'm new to esp32 and I can not find simple examples that could help me to generate a dshot signal using DMA to GPIO transfers. The dshot protocol is digital protocol to comunicate with ESC used to drive quadcopter motors for example: https://www.rcgroups.com/forums/showatt.php?attach...
