Hi trustmiao, please check the content of your PATH environment variable. It seems that it invokes the MSYS python. The path to Python which you installed for Windows CMD must be earlier in PATH then the path pointing to the MSYS binary directory. G:\esp_vsc\.espressif\python_env\idf3.3_py3.8_env\S...

I installed idf3.3 with python 3.8. in windows CMD tested ok. and then installed "espressif idf 0.2.1" in vsc, after a successful installation. In f1 menu, "esp-idf build", "esp-idf flash" all work perfectly. However, when I try to use "esp-idf monitor", it is error : G:\esp32_apps\blink>set IDF_PAT...

We wish to save settings into nvs, but maintain a factorysettings which can be restored on requirement. Therefore, we wish we could save the factorysettings(coded in) into nvs on the first reboot after flash, and then read the nvs for settings after every other reboot. is there a way to make such a ...

FYI,

its working now, bno requires i2c clock stretching and the default value was hard coded in the i2c driver. after increasing the value, it started working.

As we are still struggling with stable i2c connection, may I ask, which value did you play with

thanks alot, problem solved, we should not i2c_cmd_link_create twice.

while we test basic i2c functions, esp32 reset around every 7000 loops. back trace point to xSemaphoreHandle new_sem = xQueueCreateMutex(mutex_type); if (!new_sem) { abort(); /* No more semaphores available or OOM */ } in locks.c here is the code, very basic i2c functions: #include <stdio.h> #includ...

through debug line by line, we are certain, it silently crashes at cmd is defined as i2c_cmd_handle_t cmd = i2c_cmd_link_create();

it continuously happend in differnt part of program but same when runing i2c_master_stop(). Any suggestion can I get?

We are writing around i2c and uart functions, which gets data from i2c and send to uart. However, it restarts, after a while, without giving any information(or maybe we don't know yet how to acquire the information). ets Jun 8 2016 00:22:57 rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) conf...

as a record, I solve the problem by adjusting
I2C[i2c_num]->timeout.tout = 200000;
in driver/i2c.c - i2c_param_config:

Though this is an old post, I wish very much to know whether/what solution did you find. I've experienced exactly the same trouble while I am trying connecting to BNO 080. I also found i2c in arduino ide, but not idf. here is the post I described my scenario, but no lock no answer. https://www.esp3...
