I have a program that needs many single call on timer interrupt; what i mean is non-periodic timer interrupt. For instance, serial port 1 may need to have a...
You don't need an interrupt to determine a "no reply" status from a serial port when your timeout is 100ms. Use the MS_TIMER variable provided in rabbit BIOS....
Umm... thanks for the reply steve. I'm actually implementing cooperative multi-tasking (not costate). Non-active task would be suspended until some one...

Thanks a lot, Scott, and thank you Matt. The reply was very enlightening, I've been in firmware industry for about 2 years but there are still many things to...

You'll like this... atof can (and will) generate an LSB error of +1 or -1.This is usually below the 'saw tooth' edge in conversion to decimal so printf will...
Hi All: Currently, I met the exact same problem as Nathan did. it shows the error from CBUF.LIB, however, I have not touched the CBUF.LIB yet. I am using the...
Sooo... I dug a bit deeper and... atof is typically straight forward, multiplying fractional parts by powers... _pow() is generating the correct values, it's...
... The direction of error depends on the string length of your value to atof() try Fraction=atof("0.5"); then Fraction=atof("0.50"); Notice you now have error...

I'm aware that depending on the number of digits of the fraction the error goes back and forth by 1 bit, hence my original wording (+ or -1)... If you care,...
I sure am... You add 0.5 FOUR times and get a WRONG answer... run my test program and see... WRONG is WRONG.... So ya do a few MACS (that multiply and...

Scott, Thanks for taking the time to run the test, which by the way shows SofTools is doing the correct thing. Also as I said, it's fmul that's broken... 5*.01...
