RTOS and low level interrupts
Well, if a person is using C and they suddenly find the need for critical timing, then it is simple enough to say, #asm { ... } No big deal.

If they are low current, use an output port pin to power them. For the IC that I used when I did this, (if I remember, it was a mega16) the total power can't exceed 200ma for all...

Oh, that makes sense. I guess I was confused by this excerpt from the help files in Codevision. "It is important to note that bit selector access to I/O registers located in...

Well, I am not at work anymore, but I did see in the datasheet that you are supposed to read the registers low first. I figured that since these registers were SRAM that it...

I think you put me on the right track with the TCNT3 read. Since the datasheet itself says that this is how it is supposed to be done and yet CodevisionAVR doesn't have it...

Hi, I am only sending out the information in the interrupt until I get it working then I will move it to the main loop. Due to the real time nature of what I am doing, I will...

Oh, should have mentioned, I first did all of this for timer1 under interrupt 0 and had no problems at all. When I tried to do the same thing under interrupt one, using the...

Hi and thanks for the reply, I am using Codevision, and I have spent hours on what should be straightforward. The latest example of code that I am using is, interrupt [EXT_INT1...

ISP not recognized with LCD on Port D
I had a similarly odd problem though with a different IC and a different connection and found that my fuses were not set properly. It wouldn't program that Mega16 when I had the...

OT: Presence/Absence Detection -- use machine vision?
I have done some object detection investigation. Essentially if you think of the entire spectrum, from very low vibrations to sound, to radio to IR, to UV, what you are wanting...
