Hi ;
I have worked with STM32F429i to generate square signal with various frequency. The value of frequency can be shown on OLED SSD1306. I configured I2C1 to connect with this display.
When I connect just Rotary encoder, i can see the change of frequency on oscilloscope, but when I connect OLED , I can get numbers on it. Unfortunately, I can not see the change of frequency when change the position of encoder shaft.
is there any advice to work simultaneously.
