ST7735

Hello all I am completely new to the community so let's start with Hello All

I have this little lovely screen made by Adafruit and I was trying to connect it to s8aw60 microcontroller.

I have set the SPI module bits that I have a specified baud rate and it looks that It can communicate with the screen, however, I have problems with making microcontroller recognizing the screen. I tried to change driver provided for Arduino and other which I found on the Internet but that failed. There is no example of using s08aw60 microcontroller. Maybe someone can give me some advice?

Thank you so much

Hi Gregory

I do not have a sample code for the S08AW but I have for the S08SH that have the same SPI module, please check the attached file, I also attached a presentation for the SPI module

I hope this will help you

Please let me know if you have more questions

have a good day.

Hi Pedro

Thank you very much for your answer. It helped me a lot :smileyhappy:

I managed to write a small program which sends bits though SPI module. I can observe the message (SPI1D) on LED bar which is mounted in my demoboard. I have a lot of problems with declaring a LCD screen. Do you have some example program for this micro controller family which links MCU and LCD screen? that would be great.

Thank you very much :smileyhappy:

Kind regards
