Thank you. It is working now. A 10 k resistor was too big... The 1 k resistor works. You saved our day!

A pullup resistor on bit 4 doesnt solve the problem. The weird thing is, that we have two blocks in flowcode, that both writes "enter keycode:" to the display. When the first block is executed it shows up as it is supposed to, but the second one shows up as "5nter keycode", and t...

In a school project with a PIC16F877 we have connected an LCD display, that is hd44780 compliant to port A. The display is almost working, but some of the strings are showing up wrong. The first character in some of the strings is wrong i.e. "5nter keycode:" instead of "enter keycode&...

Here comes the problem: When i simulate the program, the interrupt only occurs when the switch is pressed, and not when it is released. I've also tri...
