USART Control Bug

Posted by fireb1423r on May 27, 2015

Hi, I'm try to write some code to do the control of USART on my SAM3. So I am using freertosusartwritepacket(); and wait for ist return. I set USETXACCESSMUTEX | USERXACCESSMUTEX|WAITTXCOMPLETE. The funktion comes back with STATUSOK and I toogel a gpio pin after that.

But now my problem. the funktion comes back before tx is finisched! So the pin gets toggelt before the tx is finished. I selected 125k Baud. What did i do worng?

Where did the function freertosusartwrite_packet() come from? I don't believe it is something we have supplied, but could be wrong.

Regards.
