Hello
i using ldc1101 with stm32h7 MCU. I am using 12 Mhz external oscillator at CLKIN pin and coil which is come with LDC1101 EVM.
After setting these values on register
LDC1101_WRITE(_LDC1101_REG_CFG_RP_MEASUREMENT_DYNAMIC_RANGE,0x07);
// LDC1101_WRITE(_LDC1101_REG_CFG_INTERNAL_TIME_CONSTANT_1,0x90);

// LDC1101_goTo_LHRmode(Prox1);
after setting all these parameter , i am getting LHR Data Ready Error.
can any one please tell what am i doing wrong.
