i have been working on a drone and decided to move my breadboard circuit to a protoboard. so first i had the radio receiver, IMU sensor and drone's 5V battery connected. things worked perfectly. i was able to see the radio commands the teensy was picking up from the radio transmitter and sending those signals to the motor pins.
SO THEN, i soldered the four motor wires to PWM pins on the teensy. again, i have tested this on the breadboard multiple times and it was fine. but after soldering these motor pins, i plugged my teensy into the socket, saw it turn on but then get stuck in the program. so i just reconnected it and then it DIDN'T turn on.
it is sharing the same power supply as the IMU sensor, and the IMU is turning on as in its LED shines. so i don't now what suddenly happened to the teensy. i then plugged it to my computer via the USB cable, expecting that my drone power supply soldering was probably bad, but even the usb cable did not turn the teensy on!! the LED on the teensy remained off.
the drone power supply is only 5V, and i even threw in a capacitor, so i have no idea what went wrong. only danger could have been apply a greater than 5V voltage onto a teensy pin but that would only break that particular GPIO pin.
i also held the reset button on the teensy for 14 seconds since that is the factory reset i believe and still nothing. oh yea, the arduino IDE does not recognize the teensy plugged in through the USB and im certain nothing is wrong with the USB cable.
any help is appreciated!
