Hello,

Im trying to communicate via UART (USART1 stm32l100) ,...Implemented own Hardware Flow (Software way to assert and dessert ,.RTS,CTS,HRDY , according to the requirement of my application,...)

Now need to send and receive data through Software Interrupt ( Kind of Global Interrupts which can be enabled or disabled through software),...How do i achieve this ,..?

Regards,

Sanil

I think my debugger was interfering, when I ran my code with the register window closed it ran successfully.

Yes, and that's why I mentioned it here, and your [DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32Discovery/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32Discovery/USARTx-DR%20not%20getting%20updated&FolderCTID=0x01200200770978C69A1141439FE559EB459D75800084C20D8867EAD444A5987D47BE638E0F&TopicsView=https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Discovery/AllItems.aspx&currentviews=33]original/other thread. The debugger doesn't have a magic way of looking at the peripheral registers, and is often more invasive than the typical user understands.

I'm glad you resolved the issue, and thanks for providing a status update.
