[En-Nut-Discussion] Hi resolution timer isr in assembler

[en-nut-discussion-admin at egnite.de]

Hi,

for multiplexing a big LED panel I need a fast timer ISR that does that
task. I have written one in assembler but don't know how to hook it into the
main C program. Maybe someone has an example how to insert assembler code
into C and how to hook it to the timer IRQ. There should be a possibility to
use a 4kB array of characters defined in the C program with that assembler
code or vice versa.

Thank you
Thorsten
