Any chance to have it for the AVR µCs too?

Hi,

Yes, we have in plans to implement AVR architecture in the Timer Calculator.

Filip.

timer Calculator 2.0 must have 42 MHz and 84 MHz mcu (APB, AHB) clocks option.
Thanks.

Hi,

Thank you for your suggestion, I have passed this to our developers.

Nice tool, thanks for publishing it..
How about adding prescalers for the pic32.?
Thanks
Bart

Hi,

OK, I will also pass this to our developers.

Only a pitty the CAN tool only supports 100Mhz as max clock frequency

Hi,

Thank you for noticing this, I will inform our developers to increase the max clock frequency.

While this is published in the AVR area, I would expect (also) AVR architecture, but cannot find it.
Am I missing something?

Hi,

Please, look at the one of the previous posts :

Hi,

Can you give any estimation on your time shedule?

CE Wim.

This is a great tool, but you have think to expand this at the other mcu peripheral initialization? pwm, a/d, etc.
everytime in a new mcu project this is a tedius and missing time activity in all the language

Thanks, Marco

It looks like there is a problem with the calculation of timer interrupts for PICs in v2.5. You probably need to use Fosc/4 instead of Fosc to get correct values.

For example, PIC18 @ 8MHz - Timer1:

v2.5 - 100us interrupt; preload = 64733; Prescaler 1:1
v2.0 - 100us interrupt; preload = 65333; Prescaler 1:1

According to formula, preload should be 65336, but v2.5 is off way too much (probably because timer clock should be Fosc/4). I'm not sure if this offset (-3) in v2.0 is a consequence of some rounding errors. I hope it is not because integer math is enough for the calculation.

Another bug:
PIC18 @ 8 MHZ - Timer 1: If you try to set interrupt time to 100ms, you will get a popup saying "Calculation error: Value for Interrupt Time too low"

I believe the soft is correct. Timer1 is a 16bits counter, if you are running at 8MHz it will increment every 0.5us. For 100ms it will need 200 000 tick this is over 16 bits.
