Trundle firmware almost ready
A few weeks back I craked getting Visual C++ to read joystick data and send it down a serial stream. Today I’ve run first tests with the Explorer 16 board using the PIC24 device to receive and parse that data from one of the UARTs, apply a differential steering equation, then use the calculated value as the duty cycle of tow channels of PWM ready to be connected to the motor controllers.
So far, I’m on course to achieve my first goal of having a joystick connected to a PC controlling the wheelchair rather than the dedicated controller, hopefully in the first couple of weeks in January. All that’s stopping me now is wiring, mechanics, and whatever gremlins I’ve not anticipated.
