delay_us error

[PDeGr]

How can this be solved? By setting the clock speed to 20MHz?

Error: Unable to successfully create 'delay_us' for target with clock freq 19660800 Hz
Error: Unavailable timing functions used!

Hello Patrick,

I think you can solve this by using a 20MHz frequency instead.

The linker with BoostC will only produce microsecond delays if it can do them exactly. The older C2C compiler always made microsecond delay code, even if it was not accurate.

By the way, is this in your own code or is the "delay_us" call in the code for one of Flowcode's components? I thought I removed all "us" calls.

BoostC has an equivalent "delay_10us()" call which seems to compile with all clock settings - perhaps you could use this instead?

Hi,

The "delay_10us() works fine with a clock freq of 19660800 Hz.
The example I used was PhoneExamples_02.zip

Thanks,
Patrick

Hello Patrick,

I'm happy this problem is solved.

We updated the files for the mobile phone solution earlier this year and you may have old copies. If you want new files, please contact Ben on our support email address (support@matrixmultimedia.co.uk) and he will send the new files to you.

Hi steve,

It is not an old copy, it's a download from last week!

Best regards,
Patrick

It looks like the CD has changed but we have forgotten to update the download files. I will ask Ben to update these files sometime today.

Thanks for letting me know!
