JDI LPM027M128C display interfacing with Nrf52840

Hi,

I have been working on the display from JDI LPM027M128C with the nrf52840 development kit. By consulting the datasheet of the display, it seems to work with the spi but after a lot of tries and trying different spi examples from nrf52 SDK, I am not able to start the display correctly. It gives some blinks of LCD when we start and burn the code into the nrf52 controller and connect the display via spi.

Any kind of input or help will be appreciated.

Thanks in Advance,

Parents

Hello,

You need to get a logic analyzer trace to check the data on SPI (CSN, CLOCK, MISO and MOSI), then compare with the datasheet of the JDI display to check if the order of data is correct. Make sure that GND is connected between the boards, and that VDD is the same or close to the same voltage.
