Introduction Once again I am playing around with PIC microcontrollers. Now I finished a complete demo that does this: drive a 4-wire fan, in my case a Noctua NF-S12A using PWM read the fan’s tachometer output to determine its speed … Continue reading
Here is the documentation of my next step: driving the LED display. The design and the C code were not really difficult; the steps to put the results here were. As I noted before I use a PIC 16F887, but … Continue reading
This is what my breadboard now looks like. It is full and it does what I want it to do for now. Time for a bit of a code cleanup and then I can show what I have achieved so … Continue reading
Even though I use a big 40 pin PIC for my experiments I decided to try how sharing output pins for multiple purposes works. To do that I use two 74HCT573 (PDF) octal latches. The goal is to drive 16 … Continue reading
