Re: Question about esp32.com forum

Hi rudi,

thanks but unfortunately youtube don't give me a youtube.com/user/pcbreflux for my user pcbreflux only https://www.youtube.com/c/pcbreflux.
Ok, its only cosmetic but it would be nice to enter a real URL in the setting to avoid this.

Re: [Video] ESP32 - Using displays and the U8g2 library

see u8g2_esp32_hal.h
#define I2C_MASTER_FREQ_HZ 1000000 /*!< I2C master clock frequency */

Re: [Video] ESP32 - Using displays and the U8g2 library
