Hi ,

I'm using ST7540 Eval Board and i want to send to my Micrcontroller via SPI , 24 bits

all at once

. The spi i use is 8 bit.

Here is an

excerpt

of my code :

volatile uint8_t i=3;

while(i>0){

i--;

SPI1->DR=data[i];

/* Control Register Write */

REG_DATA_1;

RxTx_0;

NSS1_LOW;

}

/* Wait for SPI transfer to have fully completed */

while(!(SPI1->SR & SPI_I2S_FLAG_TXE));

while(SPI1->SR & SPI_I2S_FLAG_BSY);

NSS1_HIGHT;

.....
