Hi: I used the Pin 40 to test the IOs. GPIO08 in pinmux file corresponding to PBB.01 at /sys/kernel/debug/gpio " grep PBB.01 gpio-325 (PBB.01 cd /sys/class/gpio/ echo 325 >export cd PBB.01 echo out > direction …
It will generate the required high voltage the counting tubes need to operate and it will safely invert the counting impulses to a falling edge, detectable by a GPIO Pin on the PI. But it's also designed in such a universal way in order to be very hackable. Basically it can be ...
