[Solved] Compatibility of ESP32-C3 TWAI bus and TCAN3413

Hello,

I'm building an app that reads data from a car CAN bus.
It uses TCAN3413DDFR ( https://www.ti.com/lit/ds/symlink/tcan3414.pdf ) connected
to an ESP32-C3 module.
The test app is built around the listen-only example of esp-idf.

The signal looks good at the output of the TCAN3413 but I receive ...

Re: Timing issue for blinky while using some gpios and bt_controler


ESP-IDF 4.4.5 on ESP32-S3
The "none of them" in previous post was about the question you modified which asked for os tick.

Re: Timing issue for blinky while using some gpios and bt_controler

Hello,

None of them.
Btw, I'm back from lunch, the board has been power cycled and it does not occur anymore!

The dark side certainly...

Thanks for your help.

Timing issue for blinky while using some gpios and bt_controler

Hello,

I have "timing related" issues while using together several IO as outputs and bt_controler.

I've built a minimal code and you'll get some explanations below:


#include <string.h>
#include <sys/stat.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_log.h"

#include ...

100 mA avg current consumption with BLE gatt client example. How to minimize?

Hello,

I'm having a try with ESP32s3 and the bluedroid gatt client example.

This device connects to a custom board which is composed of a single button and an nRF chip.

My goal is to have the esp32s3 react "instantly" (from a human point of view, 200ms should be ok).
ESP32s3 does not transmit any ...
