Hi Vasile ... If the flag is not cleared and you execute a retfie the ISR will reccur inifinitely. Its the flag that forces the program counter to the...
Hi all, ... This is not correct at all. Not all interrupt flags must be cleared by software i.e. usart module: "Flag bit TXIF is set when enable bit TXEN is...
Does anybody have the JAL-syntax file for Kate (KDE editor)? I remember I once downloaded it from the internet but I can't find it anymore. It should end in...
Hi, Shawn, thaks for your reply. I got the picture now. But I still have a doubt: How can I join the two bytes to make the calculation? ex. 128/1023, if the 01...
Hi all. I have run into another nasty jal bug (actually a familiar one). I know my code is good because merely moving around the order of the includes fixes...
Hey Marcelo, That's where things get a little bit more complicated but it is still pretty easy. The way you handle the 16-bit arithmetic depends on how...
... The "working" jal 4.60 version is more than 15000 lines, where would I begin? Am I the only one to notice this size "issue"? Am I the only one to try...
Hi Javi I didn't say clear the flag by software, I just said the flag had to be cleared. In this case the interrupt flag is cleared by loading the register. ...
... The path-setting is OK, but in stead of executing 'XWisp2' you should execute 'XWisp2W'. But if you want Xwisp2w to do something useful, you'll need to...
Thanks Rob, I'll give it a try. bill ... From: "Rob Hamerling" <r.hamerling@...> To: <jallist@yahoogroups.com> Sent: Friday, April 01, 2005 12:18 PM ...
indeed an interesting discussion, ... ... I use interrupts in more then half of my projects, so I should be aware of all the problems, but still keep falling...
Hi Bill, ... Assuming you are not familiar with the commandline interface, the following should be done (to be adjusted for your directory and file names!) ...
Stef, This is a great list! This would be a valuable addition to the faq. I use isr's often to increment or decrement counters in a timely rate. I don't handle...
hi Joep, ... thanks. ... Yes, I that's also a good example. And of course you reload the timer through addition ? (16) ! and I forgot 17- take care (disable...
Thanks Rob, for the great support. You're right, I'm not at all familiar with command line interface. I've been trying to get this going by using a Dos 6.1x...
Good evening everybody, I would like to ask if you people could help with a little problem. I am trying to get the analog value, using the AD conversion. I...

... Rob, For 8 bit A/D use the library f877_modules.jal written by Javi. Should be available at www.japus.org , but there appears to be a problem with his site...
... I just assign the value, but I hardly ever disable interrupts, so the 'drift' will be pretty constant. How do you achieve (16) without (13) and (15)?...
... Thanks. They do look interesting. But I guess I better just stick with the simple, but perhaps ugly, method that does not require a multi-tasker. If I...
... It would be very difficult to 'save the context' without cooperation from the compiler. It is basically the same problem as calling a procedure from both...
... Using a (software) stack to store local var's (like C does) would solve this. Why did you choose for the current sollution and not for the stack-based...
