Hello, it's me again =) I have a Problem (What else?):
First of all: uVision3 with an ARM7TDMI-S on LPC2148, ARMC-Compiler V3.1...
I'm using Nested Interrupts from KEIL: http://www.keil.com/support/docs/3353.htm
They worked fine. But now, I try to fit them into the USB-IAP-Bootloader. (From KEIL too =) This mix crashs!
My Diagnostics: The Bootloader uses Registers I use for nesting my Interrupts.
My Solution: None! =(
So, could anybody help me again? It would be great!
Thanks for all Replys!
Best Regards, Adrian
Can't you measure the time with capture registers, so you just read out the exact value (with 100ns or better resolution)? The timers can do more than just busy-run.
