TDC1000: Only able to read CONFIG_0 register but not able to read other registers.

Hello Alihussain,

Thanks for posting to the PS forum! Do you mind sharing a logic analyzer capture of what your SPI read packets reading CONFIG_0 and another CONFIG register may look like?

All registers on TDC1000 will only require you to read 1 byte of data, there are no registers larger than that on this device.

Thanks Issac for replying,

I don't have setup of logic analyzer with me. If you can help out me without that it will be helpful.

Following is my SPI read function:

uint16_t tdc1000_read(uint8_t reg) {
HAL_GPIO_WritePin(SPI_NSS_GPIO_Port, SPI_NSS_Pin, GPIO_PIN_RESET);
HAL_SPI_Transmit(&hspi1, reg, 1, 100);
HAL_SPI_Receive(&hspi1, spiData, 2, 100);
HAL_GPIO_WritePin(SPI_NSS_GPIO_Port, SPI_NSS_Pin, GPIO_PIN_SET);

return spiData[1];
}

Hello Alihussain,

Glad to hear you were able to figure it out. Please feel free to start another post if you need help with anything else!

Best,

Isaac
