Hello I don't understand why I get value aroung 1.3 Gauss ?
LIS3_CTRL_REG2 = 0x00; // Full scale +/- 4 G
LIS3_CTRL_REG1 = 0x1C; // ODR=80Hz, XY LowPower
LIS3_CTRL_REG4 = 0x00; // Z LowPower
LIS3_CTRL_REG3 = 0x00; // Continuous-conversion mode
LIS3_CTRL_REG5 = 0x40; // BDU = 1
and I receive :
LIS3_OUT_X_L = 0xEB
LIS3_OUT_X_H = 0xEE
=> MagX = 0xEEEB = -4373
LIS3_OUT_Y_L = 0x94
LIS3_OUT_Y_H = 0x07
=> MagY = 0x0794 = 1940
LIS3_OUT_Z_L = 0x4A
LIS3_OUT_Z_H = 0x1E
=> MagZ = 0x1E4A = 7754
Magnetic calculation : Mg = sqrt ( MagX*MagX + MagY*MagY + MagZ*MagZ ) / 6842 = sqrt ( 83011245) / 6842
Mg = 9111,05 / 6842 = 1.33 Gauss ????
I get this value with 2 Lis3mdl and same code.
This result seems to be wrong ? Normaly I should get something around 0.5 Gauss isn't it ?
Is there anything bad in my logic ?
Thx for your help
