 |
|
Greetings.
I am upgrading operational software from at2313 to attiny861.
The Bascom compiler does not seem to accept "Config Timer1 = Timer , Prescale = 1"
The statement line does not default to TIMER1 in red capitals for attiny861 as it does for at2313.
Both programs compile without errors and the attiny861 operates well except for the LED programmed to timer1.
I would appreciate whatever assistance is given as I am heavily committed to the attiny861 upgrade.
Compiler version :2.0.7.3
Compiler build :2.0.7.3.001
IDE version :2.0.7.3
Windows OS :Windows 7 Professional
Windows SP :Service Pack 1
Thanks and cheers.
Robin. |

If one suspects a certain part of code, one usually reduces the code till only that part is left.
First step would be writing a simple program using timer1 for blinking a led.
| Code: | Tim0_isr:
If Y = 251 Then
Return |
This leads to wrong content of registers, stack overflow and disabled interrupts, as the early exit by "Return" omits restoration of saved registers and exits the ISR with a RET instead of a RETI.
You can not use "Return" within an ISR, there has to be only one "Return" and it has to be at end of ISR.

This code will not work correct on any controller type. |

Thank you very much MWS for pointing that out, I have corrected it .
However the compiler still seems to not recognise the "Config Timer1" directive, and only with the attiny861!!!
Which ever programs I load into my Bascom compiler that use timer1, on a variety of chips, it always displays as TIMER1 in red capitals.
"Config TIMER1 = (red) Timer (blue), Prescale = 1024"
For the attiny861 program it displays as "Config Timer1 = Timer , Prescale = 1" all in blue text and not capitalised as TIMER1.
Obviously this happens instantly the line is entered and well before compiling.
Thanks again.
Robin. |

Don't be so focused on that syntax highlighting thing, timer1 works as it should.
Did you do as I suggested ?

Beside that, and without wanting to be cruel, your code is a mess. The only thing sure is where it starts, but not where it ends.
I did stop thinking about how it will run, as I saw the crisscross-jumping all around, this is no proper way to write a program.
That's why I pointed out the obvious and gave you a hint in a direction how to check the basic functionality of timer1. It seems to me you did not follow that hint, instead you got stuck on how the IDE colors the word Timer1, which btw. has nothing to do with functionality of the program. |
