Hi,
I am using AFE4300 for measuring Bio-impedance using BCM channel and Weight Scale channel to measure ECG. I am able to get Bio-impedance signal using BCM channel but in I am not able to power on Weight Scale fro end and power down BCM front end. Here is my sample code. AFE_Write_Config_Reg and AFE_Read_Config_Reg functions read and write to AFE4300 registers respectively.
////////////////////////////////////////////////////////////////////////////////////
AFE_Write_Config_Reg(DEVICE_CONTROL1,0x06); // BCM power-up, Weight scale power down
__delay_cycles(50000); //delay to stabilise
AFE_Read_Config_Reg(DEVICE_CONTROL1); // Successfully returning the written value 0x06
AFE_Write_Config_Reg(DEVICE_CONTROL1,0x6005); // BCM power down, weight scale power up
__delay_cycles(50000); //delay to stabilize
AFE_Read_Config_Reg(DEVICE_CONTROL1);// returning default value 0x0000
//////////////////////////////////////////////////////////////////////////////////
Writing 0x6005 to DEVICE_CONTROL1,0x6005 also resets the ADC_CONTROL_REGISTER1 to its default value 0x01C3.
