RE: Connect LCD (LS013B7DH03) to nRF52840 through SPI

Hi Elsa

Have you tried connecting a logic analyzer to the pins in question to check if they indeed controlled as expected? Some of the pins you refer to may used by other peripherals for instance, so please make sure that they're not.

Are you testing with a DK or a custom board?

Questions:

1. Yes. A good explanation on how you can toggle the SS pin can be seen in this case.

2. The SPIM is a SPI master instance with EasyDMA while the SPI is an SPI master instance without.

3. You need to enable the peripheral you'd like to use (SPI or SPIM) as well as what instance of the you'd like to use.

Best regards,

Simon
