128240D with MSP430 Not working


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.

Panel-simple Implementation

Hi All,

I am trying to implement this display to be recognized under the panel-simple.c implementation in Linux.


Here is the relevant section that I am adding to panel-simple.c

static const struct display_timing displaytech_dt070btft_timing = { .pixelclock = { 45000000, 51200000, 57000000 }, .hactive = { 1024, 1024, 1024 }, .hfront_porch = { 160, 160, 160 }, .hback_porch = { 160, 160, 160 }, .hsync_len = { 20, 20, 20 }, .vactive = { 600, 600, 600 }, .vfront_porch = { 12, 12, 12 }, .vback_porch = { 23, 23, 23 }, .vsync_len = { 3, 3,...

64128N SPI communications


I've been using an earlier version of the 64128N GC BC 3LP displays. I could communicate to the display via SPI if I shorted J1 and J3 together. However with the later versions of the display I am receiving now, there is no J1 and J3 pads to short.

Can you confirm if the later versions also have SPI capability and if the jumper is no longer needed or if there is anything else that is needed to enable SPI communications? The exact part number of the new display that I have is - Displaytech 64128N GC BC_3LP 220109... (More)
