I am user stm32G070 with spi connect to bme688, and find the data not correct Sample, TimeStamp(ms), Temperature(deg C), Pressure(Pa), Humidity(%), Gas resistance(ohm), Status 1, 46829, 106.39, -21015.71, 0.00, 82643128.00, 0x80 2, 49471, 106.39, -21015.71, 0.00, 82643128.00, 0x80 3, 52113, 106.39, -21015.71, 0.00, 82643128.00, 0x80 4, 54755, 106.39, -21015.71, 0.00, 82643128.00, 0x80 5, 57397, 106.39, -21015.71, 0.00, 82643128.00, 0x80 6, 60039, 106.39, -21015.71, 0.00, 82643128.00, 0x80 7, 62681, 106.39, -21015.71, 0.00, 82643128.00, 0x80 8, 65323, 106.39, -21015.71, 0.00, 82643128.00, 0x80 9, 67965, 106.39, -21015.71, 0.00, 82643128.00, 0x80 10, 70607, 106.39, -21015.71, 0.00, 82643128.00, 0x80 then run the self test check code, and got fail result: API name [bme68x_selftest_check] Error [-5] : Self test error Self-test failed and I found that data[0].idac == 0, it mean that no heater, so write the reg 0x5A for a value , and then read it out, the register 0x5A is still 0x00 the timing waveform is correct, so what can I do?
