Hello There,

i'm trying to configure the LIS2DH for the free-fall detection. On the Free-Fall LIS should trigger an interrupt on INT1. My configuration looks like that:CTRL_REG1 = 0b00100111;CTRL_REG2 = 0b00000001;CTRL_REG3 = 0b01000000; CTRL_REG4 = 0b10001000;CTRL_REG5 = 0b00000000;CTRL_REG6 = 0b00000000;INT1_CFG = 0b10010101;INT1_SRC = 0b00000000; // Read Only?!INT1_TSH = 0b00011000;INT1_DUR = 0b00110010;it doesn't seem to work propperly ...can anyone help me? #lis2dh #free-fall

Hi,

I try to do the same without success ( juste a threshold) . I don't understand why int1 pin is never asserted...My config :CTRL_REG1  0x77CTRL_REG2  0x01CTRL_REG3  0x40INT1_CFG  0x2AINT1_THS 0xC8  for example
