Hi Leigh,

interrupt Still not triggering in software mode i put the FCD file in C:\ProgramData\MatrixTSL\FlowcodeV10\FCD\ARM,
restart and recompile to chip .

[LeighM]

Were you able to create interrupt icons for B7 (EXTI7 port B) and A3 (EXTI3 port A) and set the called macros, and compile ok?

[Alan_37]

Hi , ohh ok i thought RX int , Yes now the interrupts are being triggered
but the data is not being recived properly , I send something and it reply
with something else

[LeighM]

OK. You will need to remove the previous UART RX interrupt icons.

Leigh , Ok working was my fault i set the interrupt on rising edge

Now software mode working Fine Thanks for your help

Regards Alan

Hi Alan,
I think I've replicated your hardware UART RX interrupt issue,
so I've made some changes to the UART RX interrupt code.
Please could you try this with your earlier UART RX interrupt test ...

If this works for you, the Matrix team can validate and update the official versions.

Hi Leigh,

Sure will test tomorrow and let you know

Thanks

Hi Leigh,

I can confirm that the bug is now fixed 100%, have connected the RX of U1 and U2 together
so that the data arrives exactly the same time on the 2 UARTS.

Sent data every 200ms, tested for 20 minutes without any problems .

Kindly have a quick look to other STM Targets that maybe have same bug.

Thanks & well done !

Regards

Alan
