Arduino Due + Assembler Clawson,
I included the .s file in my original post.
Why does the thumb code point to destination + 1 instead of destination? All the asm code I've wrote over...

Arduino Due + Assembler Clawson I appreciate your time with this.
The asm invocation is; -mthumb -D_SAM3X8E_ //Looks OK
void cdelay(int count)
{
80304: b480 push {r7...

The solution you have come up with will work but if I may suggest if you start time timer at...

Arduino Due Timer question You are pretty much right, the PIO configuration that doesn't need the clock is outputs. All Input lines and peripherals lines need the clock, lesson well learned.

Arduino Due Timer question Thanks clawson for you response. I finally got the code below to work, it was as you said the clock PIO clock was not being set. The data sheet is so hard to read and...

If you're just starting the project delete this one and start all over by creating a new solution.

I found http://labalec.fr/erwan/?p=497 by googling and it was not the only one.
Got my Atmel ICE yesterday and have programmed my IDuino Due and ATMega2560 with it, haven't tried to debug yet but so far am impressed.
Sounds like it may be a privileges problem on your source directory, check if read only or access privs..
