Trying to read the PS1 values. But as im running the following code it keeps saying on "chip_stat" that its suspended.
The code im using to read the PS1 values is the following. Im reading the value 16705. Which keeps being the same on all measurements.
The value should go up and down from 0 - 32767, as it measures more or less movement.
I linked the files for the i2c communication.

Code:
main (void){
init();// Configuration initialization
si1141_init();// Si1141 sensor initialization
__delay_ms(30);// Delay to ensure Si1141 is completely booted, must be atleast 25ms
si1141_WriteToRegister(REG_IRQ_STATUS,0xFF);// Clear interrupt source
signed int status;
while(1){
WriteToI2C(0x5A<<1);// Slave addressPutByteI2C(0x30);// chip_stat
ReadFromI2C(0x5A<<1);// Slave address
if((status =GetByteI2C(0x30))==Sw_I2C_ERROR)// part_id{
returnSw_I2C_ERROR;
}
Stop_I2C();
status++;
}
