Hi,

I Working on LPC54018-EVK . i should config spi on this Board. The first pulse of clock

Width should be high(On+Off =width of first pulse).And The Spi Ssel0 How can be enable.

In order to enable ssel0, we need:

1. config ssel0 pin in pin config tool. for example (this screenshot is from LPC55s69, but same for your device)

after generate code, new pin_mux.c will include ssel0 pin initialization code

step 2. set TXSSEL0_N FIFO write data register to select ssel0 spi device.

Hope this will help you

How did you configure the code?

Besides, how does it work if you use this solution ?
