jnwoofer 0 Posted March 26, 2016 Share Posted March 26, 2016 Hi all, Based on reading the 430 forum and Github Energia/Pervasive issues lists, it appears that someone has successfully setup and tested the EPD Booster with Stellaris (LM4F120). I have acquired an older 2.7 Pervasive Display (which appears to require PWM) and booster board (version 1.5). Using Energia, I can successfully directly connect using my MSP430G2553 so I know the board/display is ok. I want to connect the EPD to my Stellaris -- since there is a PWM requirement, I believe I will need to use the wireharness (instead of direct connecting) and set up a macro for PWM to connect from a Stellaris pin to pin 9 of the EPD. In the EPD_PINOUT_Energia.h under the EPD_PINOUT under sketches, I see the PWM macro for MSP430F5529 -- what is the equivalent macro and pin mapping for Stellaris? The header below it for LM4F120 in EPD_PINOUT_Energia.h simply uses Pin 9 (which is ok for the newer displays which do not require the PWM). Please advise. Thanks!

Rei Vilo 695 Posted March 26, 2016 Share Posted March 26, 2016 The trick for the MSP430F5529 was designed by a TI engineer. The LM4F120 / TM4C123 doesn't offer this feature. I see three possible solutions bluehash 1 Quote Link to post Share on other sites
jnwoofer 0 Posted March 27, 2016 Author Share Posted March 27, 2016 Ok, so I went with option 2, used the wire harness (which allows pins 2, 3, 4, 5, 16, 17 to be free) and changed from pin 9 to pin 17 (thank you PF_0!) for PWM in the header below LM4F120 in EPD_PINOUT_Energia.h.

Rei Vilo 695 Posted March 28, 2016 Share Posted March 28, 2016 Glad to know you've tinkered the BoosterPack. You're a real maker! Quote Link to post Share on other sites
