I'm using a SparkFun-built Arduino Pro Mini 3.3V / 8MHz. One thing I need it to do is toggle the gate pin on a MOSFET, and that's not working for some reason. Getting in there with a multimeter, I see that the voltage on the pin never goes HIGH. The only thing I have running on there is the following bit of code:
void setup() {
pinMode(A7, OUTPUT);
}
void loop() {
digitalWrite(A7, HIGH);
}
Any thoughts on either configuration or electronics that could be causing this?
The pertinent part of the schematic is:
