Hello Sean,

Just wanted to say that the patch works; IRQ1 now behaves as it should. Thank you for your help.

P.S. now that you've changed your avatar from Klunk to your photo: did I see you at Elektor Live in Eindhoven?

Hello Sean, Thank you for your reply. Just to make sure I'm not making it harder for you as it already is: I don't need pin PA30 (D6) to be a GPIO as well as an interrupt. It only needs to be an interrupt, IRQ1. As for the ADC: it's fairly simple to use. You don't need any code to control it, you ju...

Hi everybody, I've built two, identical, custom devices with the AT91SAM7S321 as main microcontroller. The device's ADC didn't work as expected, so I started bugtracking (again :roll: ). The ADC pulls a signal line low when there's a new sample available. This signal line is connected to pin D6 (har...

Hello Ben, Thanks for the reply. I've read the file you mentioned and now I know why everything was mixed up: the pin mapping was indeed all wrong. I've corrected the errors and now it works as expected (but this should be fixed in the next release to avoid confusion for others). As a note to others...

Hi everybody, Recently I built a custom device with an AT91SAM7S64-microcontroller from Atmel. The schematic is based on an evaluation-kit from Olimex, this one, to be precise: http://www.olimex.com/dev/pdf/ARM/ATMEL/SAM7-P64-SCH-REV-E.pdf . Alas, the AT91SAM7S64 is insanely difficult to get; it's m...

Hello Ben, That's strange, but you're right. Today I noticed that another Flowcode program suddenly showed the right characters in the terminal program, without having changed anything significant in Flowcode. It would seem that terminal programs like Tera Term Pro and Hyperterminal sometimes automa...

Hi everybody, I'm having a rather strange problem when I try to send the contents of a string variable over RS232 to a terminal. Say I want to send the text "TEST" to a terminal display; there are a couple of ways you could do that. I've made a test program that does the following: Set a string vari...
