Posted on December 27, 2015 at 15:58Hi.
I am trying to work with STM32L051x8 MCU (IAR 7.2 IDE) with 2 USART ports in combined mode:
1) RX define and operate in Interrupt mode.
2) TX define and operate in DMA mode.
When I configure RX and TX to IRQ mode I view both RX and TX operations. But in combined mode (as described below) I don't view any activity on USART communication.
Attached very simple project with combined configuration. For start DMA transaction I set variable ''ready'' = '1'.
Can you help to find the problem: why communication does not work?
Thanks.
