I am not getting any LP or Rp Data. Am i missing something? can anyone help me? below is my config param.
int8_t ldc1101_init()
{
uint8_t chip_id;
// chip_id = ldc1101_readByte( _LDC1101_REG_CHIP_ID );
// if( chip_id != 0xD4 )
// {
// return;// DEVICE_ERROR;
// }

while(1)
{
read data();
}
I am getting following value:-
