When I use this code I get a respons on my SPI1 .. [testing SPI1]
Code: Select all
/*
* SPI bus contender 1.
*/
static THD_WORKING_AREA(spi_thread_1_wa, 256);
static THD_FUNCTION(spi_thread_1, p) {
(void)p;
chRegSetThreadName("SPI thread 1");
while (true) {
unsigned i;
/* Bush acquisition and SPI reprogramming.*/
spiAcquireBus(&SPID1);
spiStart(&SPID1, &hs_spicfg1);
/* Preparing data buffer and flushing cache.*/
for (i = 0; i < SPI_BUFFERS_SIZE; i++)
txbuf[i] = (uint8_t)i;
/* Slave selection and data exchange.*/
spiSelect(&SPID1);
spiExchange(&SPID1, SPI_BUFFERS_SIZE, txbuf, rxbuf);
spiUnselect(&SPID1);
#if defined(SPI_LOOPBACK)
if (memcmp(txbuf, rxbuf, SPI_BUFFERS_SIZE) != 0)
chSysHalt("loopback failure");
#endif
/* Releasing the bus.*/
spiReleaseBus(&SPID1);
}
}
But when I am not running this thread and use the code below I get nothing... the shell is working and the command tree gives back: File System not mounted
But on my logic analyzer I see no electrical respons or signals... what can be wrong? My board.h is changed to SPI1 and the pins:
PB5 [ALT.FUNC 5] = MOSI, PB4 [5] = MISO, PB3 [5] = CLS/SCK, PA15 [analog and tried AF:5] = NSS/CS
Code: Select all
