Mar 17, 5. Pin 3 of the IC is connected to the junction between If you have to use this you need to use the resistors as in the AN, you need to write a bit bang SPI taking care of timing requirements! Mar 22, If not then more drastic measures will be required including a “vampire” connector that taps into the existing circuitry or desoldering and isolating the chip so that you can get to the signal lines without interference.
