"SPIx_Init_Advanced" for Stellaris M3, MikroPascal

[Orionsem]

Hi everybody,
I am using a Mikromedia M3 ARM board with a TI Stellaris LM3S9B95. But when I initialize module SPI0 connected to port bits PA2, PA4, PA5, the board locks up, using this command:

-> SPI0_Init_Advanced(400000, _SPI_MASTER, _SPI_16_BIT OR _SPI_CLK_IDLE_HIGH, _SPI_FIRST_CLK_EDGE_TRANSITION);

when I initialize using SPI0_Init, the board works normally.

I need to use the Advanced mode because I have 14 bits DACs connected to this SPI.

Can anybody help me please? thank you in advance!

Please try this and see if it works, it worked for me

Code: Select all

void main() {
 
 SPI0_Init_Advanced(2000000, _SPI_MASTER, _SPI_8_BIT | _SPI_CLK_IDLE_HIGH, &_GPIO_MODULE_SPI0_A245);
 
 while(1){
 SPI0_write(0x0F);
          }
 }

Best regards,
Aleksa
