//I am using adxl345 with ESP32 in MDF for update value every 1 second of x, y, z axis in xmin, xmax, ymin, ymax, zmin, zmax and //send data after 5 minutes. so when I read data for x, y, z it is fine but when I want to compare and update the value in xmin and //xmax is not update properly. my code snippet is below kindly help me with this. thanks in advance.

Code: Untitled.asm Select all

// Read data of x, y and z with this code

//Read ADXL345 DATA

#define ADXL345_CAL_AX 0x32

#define ADXL345_CAL_AY 0x34

#define ADXL345_CAL_AZ 0x36
