Hello,
the last time i work with a Atmel AVR (AT90CAN) and now i want to start to program with a ARM AT91SAM7X(C).
So i'm searching for some examples and documents to use this microcontroller with µvision3 (16K Testversion).
Especially i'm searching documents and examples for the Interrupthandling with this controller and Keil. How can i use Interrupts and where can i find the namens of the interrupts? Have i to modify the SAM7.s File?
My intention is to use the USART and the CAN interface with interrupt handling (both).
I hope you can help me to get a good start with KEIL and this microcontroller.
Yours faithfully Jens
hmmm i have searched by the examples at the support link. But i haven't found a really good one with a documentation.
the examples i found has no documentation and i don't know why they do all the things in the code.
i'm searching for a step by step getting started document to learn how i use the keil development tool with a sam7x.
the first step is to "include" (i'm clicking yes at the question, if KEIL should generate this file) the Startup file, right? Did i have to modify this file in any case?
then i include the libs: #include "AT91SAM7X256.h" #include "lib_AT91SAM7X256.h" #include "AT91SAM7X_EK.h"
right???
and then i can use the functions from the lib_AT91SAM7X256.h file? Is there a documentation for this function? online help, pdf or something?
but after this step i still don't know how i can use a interrupt and how to include it.
in the examples i dont't find a good one with documentation :/
so please help me.
