STM32F407ZG Uart ( Software Mode)

Post by Marko_2001 »

Hi,

Just started playing whit STM32, I need to have a UART in software mode but
it seems that there is a bug. I am running a very simple code just init the UART and send
a char (53) @ 19200 should translate in ASCII: 5 but the output from the chip
is very strange.

STM32 is running @ 16MHZ and it works fine in channel mode so it not a frequency problem.

hello LeighM ,

I can see that this bug is also present on V7.3, I was wondering
is Flowcode 7 still supported for this type of Bugs do we still get bug fixes?

cos I can see that the cumulative update tread in flowcode 7 is quite old
Is there a link we can access to download bug fixes?

Hello Alan,

I've added Leighs fix to the v7 update zip file now.

Going forward as we add new features and overhaul functionality it becomes harder and harder to apply backward compatible fixes. So initially we do it a lot but over time as less people are using the previous older versions we start to reduce the amount of fixes until it's just the specific v7 requests that get the backwards fixes.

Hope this helps.
