mondo8205 0 Posted December 7, 2014 Share Posted December 7, 2014 Ok I have looked all over and can not find an example code for the following SparkFun LCD Display. I have a MP430g2452 and the following LCD Display: https://www.sparkfun.com/products/9394 It just has Vcc Gnd and Rx. I just need a very simple "Hello World" code. Can anyone point me in the right direction. Thank you! Quote Link to post Share on other sites
yosh 121 Posted December 8, 2014 Share Posted December 8, 2014 Hi, it's a 5 volts display ... The Launchpad e.g. only has 3.6 volts! Quote Link to post Share on other sites
Rei Vilo 695 Posted December 8, 2014 Share Posted December 8, 2014 ...so you need a logic level translator. Search for I Quote Link to post Share on other sites
abecedarian 330 Posted December 8, 2014 Share Posted December 8, 2014 It says "... takes a TTL serial input ...." Theoretically, MSP430 does output a TTL compatible signal, as in logic "low" is under 0.8v and logic "high" is above 2.8v... if the MSP itself operates at > 3v ... so it should work if the display itself gets 5v0 elsewhere, I would think.

mondo8205 0 Posted December 8, 2014 Author Share Posted December 8, 2014 My Vcc is 5V and my Rx is connected to the P1.1. This should still work, right? What about the hello world code for this, does anyone have a sample? Quote Link to post Share on other sites

mondo8205 0 Posted December 10, 2014 Author Share Posted December 10, 2014 Aren't those example codes for Arduino? Quote Link to post Share on other sites
yosh 121 Posted December 10, 2014 Share Posted December 10, 2014 In Energia it could/should work. You could replace SoftSerial by Serial and use the Hardware Serial. But anyway, it's still possible that 3.6V are too low for the logic ... Just give it a try. Quote Link to post Share on other sites
