Hi,
I have a problem with connecting the TFT screen to Pro Micro. I will thankful for any help.
I'm not any specialist in Arduino. This is one of my first projects, so please explain very simply :).
I created a program code compile and load onto Arduino Uno. Everything was fine, program worked properly. But due to problem with place I decided to buy a Pro Micro and now its a problem because the program doesn't work and I do not have any idea whats is wrong. If somebody can help my, provide my some ideas I will thankful.
Chosen device on IDE: Arduino Leonardo (according to instruction)
Arduino ProMicro TFT screen 1.44
pin 8 ---> DC
pin 10 ---> TCS
pin 16 ---> MOSI
pin 14 ---> RESET
pin 15 ---> SCK
