CCS/CC2640R2F: SSD1351 OLED Display Interfacing

Tool/software: Code Composer Studio

Hello,

I am trying to get the SSD1351 OLED display hooked up and running with the CC2640R2 development board. I have searched around and found some people who got a similar display (SSD1306) working with an MSP430 here: https://e2e.ti.com/support/microcontrollers/msp430/f/166/p/612318/2254444 so it should be possible. Comparing the code from that post to the Adafruit library.h file here: https://github.com/adafruit/Adafruit-SSD1351-library/blob/master/Adafruit_SSD1351.h , it is clear that the display commands are different values. I'm having a hard time getting this sorted out to work with the CC2640R2.

Thanks in advance,

Josh

Hi Josh,

Yes this is very much possible using the CC2640R2F's SPI driver that is documented here:

There you can see example code snippets that demonstrate read and write use cases.

To get you started, in essence what you'll need to do is port over the void Adafruit_SSD1351::begin(void) function found here: https://github.com/adafruit/Adafruit-SSD1351-library/blob/master/Adafruit_SSD1351.cpp

Specifically, you are going to want to replace those writeCommand and writeData functions with the appropriate CC2640R2F SPI API functions.

I did this and it worked great! Currently using an open source uGUI for graphics and everything is working. Thanks!
