Serial com-port communication with autoIt

This weekend I found out how to read from / write to a com port with autoIt code. I created a file with some functions that read/write single characters or lines. To communicate with a com port, I use the CreateFile function from Kernel32.dll.

Scope with PIC microcontroller and Matlab

After many trials I recently succeeded in using the serial connection for communication between my PIC experimental board (based on a PIC18F4455) and my laptop. Turned out I was configuring my UART wrong, but now it works. I’m very happy about this because it is very useful for debugging my robot controller. I wrote a script in Matlab to read out the sensorvalues from the COM port and plot them in some sort of scope-window. The result looks pretty cool!
