EVM430-FR6043: LCD NOT WORK

Do you mean that the code have worked properly? Are the code is the demo example for this board?

If the code is same, I would ask you to use oscilloscope to test the LCD pin directly to check if you can find wave on that pin.

Hi Eason，

We had two boards of EVM430-FR6043 and both of them the LCD DIDN'T work at beginning. One has the Originally code. Another one were loaded MSP430FR6043EVM_USS_Gas_Demo and this one the LCD worked one times by push the on board buttons "Left" "Right" "Select".But only one times it works and after that no matter how hard I try there No display at all. O.M.G.! What a coincidence ! I test all pins of LCD,there are nothing on them when LCD didn't work， no wave no voltage（include R3,R4,R5,R6). When LCD work they have wave or voltage. My feeling is the LCD didn't be driven. What can I do for this? Please help me!

THANKS

You can try this demo:https://www.ti.com/tool/download/USS-SWLIB-GAS

Then you can enable the LCD:
