Dear TI,
I'm struggling for days now to get the asynchronous serial mode working. For some reason i dont receive anything on my 433.92 Mhz receiver.
This i've tested right now:
- settings the CC1101 config and read it back to make sure the config in the cc1101 is set
- testing if there is a signal on the gdo0 pin
- Testing SPI communication with logic analyzer. (i've received data anyway)
- Tested the receiver with a 433.92Mhz remote controller
this is the driver im using:
The main code:
static struct sCC1101 gCC1101Settings = {
0x0B, // IOCFG2 GDO2 Output Pin Configuration
0x2E, // IOCFG1 GDO1 Output Pin Configuration
0x2E, // IOCFG0 GDO0 Output Pin Configuration

};
struct sCC1101PhyInfo gPhyInfo;
struct sCC1101Spi gSpi = { SpiInit, SpiRead, SpiWrite };
uint8_t gPaTable[8] = { 0x60, 0xC0, 0xC0, 0xC0, 0xC0, 0xC0, 0xC0, 0xC0 };
int main(void) {
// mcu init
sysclk_init();
board_init();
udc_start();
kk_init();
// cc1101 init
CC1101SpiInit(&gPhyInfo, &gSpi, NULL);
//CC1101Reset(&gPhyInfo);
CC1101WriteRegisters(&gPhyInfo, CC1101_PATABLE, gPaTable, 8);
CC1101Configure(&gPhyInfo, &gCC1101Settings );
CC1101Transmit(&gPhyInfo);
kaku_send(13,14,1,0); // send a signal to GDO0
Please help me to fix t his, because it really drives me crazy.
