Hello, just a quick question to see if anyone has run across this problem before. I'm working on a project using the STR9, and utilizing both UARTs. We've found that when we include the line "GPIO_InitStructure.GPIO_Alternate = GPIO_OutputAlt1" in the configuration for GPIO9, UART0 (when used on P6.6 & P6.7) becomes unresponsive. I've looked at the pinouts for any settings that might be conflicting, and come up blank.
Anyone ever had a similar situation? We are unable to move the UART to another port, so that isn't a viable option for us.
Chip: STR912FAZ44H6 Coded with uVision and the latest libraries available.
