- PIC16F877A on the sensor board is mounted and first led test is OK! A problem occured with the 20MHz smd XTAL. It is solved by unmounting 22pF capacitors. Why they caused a problem is unknow yet! But we have realized that two different but same part numbered XTAL has different pin out style. The pictures clearly shows this inconsistency. :S
- A simple serial communication test is also performed successfully.
- Now it is time to move on first sensor....
