  1. MSP432 version of my Universal Graphics Library. Works with my latest Color LCD BoosterPacks, 2.2" and 2.4" (320x240) Touch support will be added in late April. ugl432.zip
  2. Hi everyone, I did a quick port of these two libraries to Energia on Stellaris. You can find them here: https://github.com/jscrane/Adafruit-ST7735-Library https://github.com/jscrane/Adafruit-GFX-Library Note that I used digitalWrite() rather than messing with port registers. The speed doesn't seem too bad all the same. At the moment, I have only tested with hardware SPI. If you inspect the changes I had to make for Energia, it might help with porting further libraries to Stellaris. Cheers, Steve
  3. I was trying to get the Tiva Launchpad TM4C123 working with the Nokia 5110 using Energia. Eventually I came across this page: http://www.clarenceho.net/2015/08/tm4c123-with-dht11-sensor.html You can follow the series of questions and answers through which Clarence Ho helped me get the combination working. You can see that he used a library originally by Rei Vilo, modified to add a contrast command. You can see also that Clarence has now added the jump-wire connections which are needed to link the Launchpad and LCD, near the top of the page. I then investigated graphics, and added Graphics com
  4. While searching for a font creator I found an interesting one here: http://www.mikrocontroller.net/topic/99701#865331 It creates fontdata that are bit aligned so was a bit tricky to render but I have managed to create code that does that. By default it generates proportional fonts (from True Type) and also includes the top bit set characters that I need for my radio library. So, here is my initial code for rendering fonts generated by this utility - please note it is cannot handle fonts higher than 24 pixes. Add as font.h or to graphics.h: #include <stdbool.h> typedef struct F
