Problem with indexpuls on spindle ,The reading on the imput 10 GPIO 22 for the indexpuls is 0.5 volt ac and the reading on input 11 GPIO 24 is 0.2 v ac , I dont know
the settings in HAL file for this and I need help to find the right values for correkt reading in the Hal file ,i dont know the right place to play with these numers , I can read the signal on the input at the chinese breakout bord and after that the signal disepere nothing in the Halmeter or Halscope. My set up is Raspberry pi 5 and this
