![]() Perhaps you can try this experiment - connect a 33k resistor from the pin youre receiving crosstalk on to ground. If this is not the case, then maybe your peripheral has insufficient drive strength and a buffer amplifier might be necessary. ![]() When your GPIO pins are being driven by an input, they would have a lower impedance and be able to sinksource enough current to maintain the pin at the intended level. Generally speaking, input pins are high impedance and will basically react to environmental noise, mains hum, capacitive coupling between adjacent pins, static electricity (which can kill them) etc. Nana yaw asare adomakoma audio free downloadĪll show crosstalk between GPIO 2,3 with some being GPIO 2, 3 4. I have extended this same test to three new Pi 3B just removed from the package and get the same results. I am using the python script below substituting the pin 3 pin 5. ![]() In the GPIO 2 monitor program, when GPIO 2 is pulled low, I get a trigger event for GPIO 2 and GPIO 3.Īfter obtaining the same results across a Pi 2 Pi 3, I opened a new Pi 3B never used and got similar results. I am using GPIO.eventdetected to detect events within the programs. ![]() One program monitors GPIO 2 pin 3 and the second program monitors GPIO 3 pin 5. ![]()
