Very simple Python / Tkinter GUI to send selected keystrokes via serial port
Following a query from Naomi Dickerson, I was playing around with my SerialSend program, which I often use for sending arbitrary bytes or characters to a connected microcontroller circuit. Sometimes, it’s convenient to send keystrokes in real time i.e. each … Continue reading

Using a dsPIC30F4011 to generating 4 PWM signals with equal duty cycles but at 90 degree phase increments
In a recent comment on one of my blog posts, Saptarshi De posed an interesting problem: How can the dsPIC30F4011 be used to generate four PWM signals of equal (but variable) duty cycle at 90 degree phase increments? Saptarshi wants … Continue reading
