We are planning on using the Displaytech-128240D Graphical LCD. We bought a few LCD samples online and we were trying to interface with the MSP430 (MSP430F6659) series microcontroller.
We are using SPI 4 line interface and we are using the RAMTEX LCD stack.
We are using a 3v supply and used 5x multiplier capacitor circuit. But we are facing issues.
We observed that the LCD initially works (partially) but soon stops working within a few seconds. the SPI lines seem to be getting damaged, the microcontroller lines are also getting damaged and not usable further.
