Re: Pull down button on Port B

Solved: Microchip Applacation note AN552
"The series 100Ω resistors are used for Electrostatic Discharge (ESD) protection."

OK, I think I was on the right track. In fact I was considering 100Ω...

Re: Pull down button on Port B

thanks Richard for the reply. My point is to limit the current surge when the PortB pin drops from 5v to 0v at the button push. My thinking is there is a spike of current that may damage the PortB...

Pull down button on Port B

Using weak pullups on port B of 16f1936. A button to ground will cause an interrupt on IOCBN.
Question: should I use a low value resistor in line with this pull down button?

Re: Error compiling with DT Interrupts

Hi Richard,

thank you so much for your quick reply.

And once again you are 100% correct.
How could i be so blind?

Thanks. It now compiles correctly.

Re: Error compiling with DT Interrupts

INT_Handler USART_RX_INT, _RxISR, PBP, yes

dt ints does not have an interrupt called USART_RX_INT perhaps you mean RX_INT

Error compiling with DT Interrupts

Hi guys,

i'm a bit lost with a very small and simple program which does not compile when using DT interrupt library on the 18F2580.

I was hopping someone more inteligent could help figure out...
