First of all , thanks for your attention . I have a problem with the communication with 16407 (SPI) . I cannot seem to receive any kind of data . I think i am taking all the timing of the SPI from the datasheet in consideration , but i cannot retrieve any data . DOUT from the sensor is always at high level . DIO1 (that should make a pulse every time data is ready) is always at high level too . Anyone knows what's going on? Any kind of help would be appreciated! Thanks in advance!
