Logging stops working after i2c_new_master_bus()
Posted: Tue Jan 02, 2024 4:09 pm
I am using an ESP32-C3-DevLit-M1 and try to speak to a sensor via I2C. In order to do that I create a new I2C master bus using
imported from i2c_master.h. When I call this function the log stops working. There is one last truncated entry and nothing else is printed anymore. The program seem to work properly since it shows the correct behaviour. Nevertheless nothing is printed in the logs after that call. What am I doing wrong?
Log output:
