stk 500

its a good IDE for beginners, it can support almost all of the AVR's and has onboard LED's and Switches for real time monitoring and control. its also got a max202 ready for you.

jump to main() inside ISR

In codevision 1.23, how does one jump from the interrupt subroutine to main()? I'd like to a code that will uses a timer to time 2 seconds after a certain event in main() occurs. when s secs is seen in the interrupt subroutine, it executes some code lines then if should go back to a certain line in the main code other than the point where the interrupt routine goes...

I was thinking of a forced jump instruction... any ideas?

RTC on codevision

Has anyone tried using the RTC embedded in the atmegas?

Does codevision support RTC? (are there functions for this?)

Is there an external circuit (like a crytal oscillator) needed when using the RTC? If so, do the STK500 have this circuit?

Thanks a lot!

Ground Point for ESD protection

Hi all,

Does anybody know, how to "create" an earthground point for the purpose of using it as an Electrostatic Discharge Damage (ESD) protection? This office doesnt have a third terminal (ground) in the mains where i could access ground point so that i could discharge electrostatics (I need to connect my ground strap to earth ground)

Any help will do

Thanks in advance

software UART on mega16/32

Hi everyone,

Atmel's website offers application note AVR304 (interrupt driven software UART) and it has an included C code implementing the appnote. However, the example code does not use codevision, i've been trying to "convert" it to codevision syntax but i found i could not continue because the header files used are not for codevision. Does anyone have a software UART code written for codevison?

Im a begginer so i need to a code to start from.

Any help will do. Thanks in advance.
