Firs of all thank you for your time.
I'm currently working with a LIS2DE12 for its great low power current but unfortunately I'm not able to get any useful information from the device. I tried to active an interrupt in the idea to check movement in any direction (i just want an interrupt if the device is moving). It doesn't work but worst when I read the register of the acceleration i have always the same values (exactly the same even when moving, reversed, ...). I guess I have made some mistakes in my configuration but I was not able to find where is the problem.
Just below my pseudo-code. The I2C function are working correctly (I'm able to communcate with the LIS2DE12 )
write 0xC0 ACCEL_TEMP_CFG_REG // enable the measure of the temperature
write 0x57 CTRL_REG1 // 100Hz & activate all the axes
write 0x00 CTRL_REG2 // No filter
write 0x00 CTRL_REG3 // No specific interrupt
write 0x80 CTRL_REG4 // BDU activated for the temperature
write 0x08 CTRL_REG5 // Latch interrupt
write 0x00 CTRL_REG6 // no INTERRUPT on int2
write 0b00101010 INT1_CFG // Interrupt OR when over threshold
write 0x16 INT1_THS // Set the threshold
write 0x03 INT1_DURATION // Set the duration (small one)
write 0x00 FIFO_CTRL_REG // bypass mode
check if data available ( read STATUS_REG_AUX) then
check if INT1 == 1 then
LED = 1 // to be able to see the interruption
I hope that I respected the rules of this forum.
