I need to interface with 3.3V incoming signals on 5V system, so I'm going to move my 16F628 design to 16F819 to use the A/D. I found only one JAL example for...

hi, i do use a max232 and i do see the starting message sent to the serial port - but this is consistent - the output pins on the pic seem to work fine (i'm...
I want to do something with the 16C765 for USB data transfer. Any change of support by Jal. Or can I use another chip? Is there any code available? Harrie...

... Now I see it. This is silly. ... Most PIC pins are TTL inputs, which are fine with a high level of 3.3V. Check page 138 and 45 of the PIC628a datasheet:...
