uart_write() strange behaviour

[Kct@vt]

Hi,

I'm using uart_write() to send a 7 byte array out the serial port (mikroBUS 1) every second.

uart_write(&uart, frame, 7);

I have the uart library set for blocking operation (mikroSDK 2.0).

hardware: EasyMxPro v7, STM32F107VC

The 1st write sends out 9 bytes, and subsequent writes send out typically 1 or 2 bytes.
After a while, it does send out 7 bytes but not starting at the right location and sometimes it sends out values of 0 (which are not in my array).

It appears that the ring buffer code of the uart isn't working correctly?

Hello,

Would it be possible for you zip and attach your project, so we could take a look at it?
