I'm having problems reading the state of a GPIO pin.
If I use the HAL function to read the pin, it always returns that the pin is high.
But if I read it manually, then it works properly and co...
Posted on November 07, 2014 at 08:54 I'm working with an STM32F4 Discovery board, and I've been experimenting with the CubeF4 UART examples (HAL). Everything I've seen suggests that receiving takes a manual command. Example: HAL_UART_Receive(&Uart...
Posted on October 22, 2014 at 07:20For the STM32F4 Discovery board, can someone tell me exactly what pins need to be connected in order to power this externally (i.e. not via USB)? Surprisinginly, I can't find any place where this information is cle...

I have an STM32F4 Discovery board, which I am relatively new to. I'm trying to figure out how to work with GPIO's, and I haven't been able to find a good tutorial yet, so I'm trying to work it out by looking...
Posted on April 30, 2014 at 15:25I just purchased an STM32F4Discovery and I'm getting very frustrated before I've even begun working with it. All the website product pages and documentation say that there are many application firmware examples locat...
Posted on November 09, 2014 at 07:52I'm not thrilled with the HAL code either. But that's what the example projects are written in, and there isn't a good alternative, that I've found. Do you know if there's any example code out there for the type ...
Posted on October 22, 2014 at 20:04Thank you! I did look at UM1472, but I still didn't see anywhere that clearly stated how to connect the board when powering it externally. As a quick clarification, if I supply 5V in, do pins 5-6 become 3V out? If...

Posted on April 30, 2014 at 18:57Thank you all for your help. I think I figured out a big part of the problem. All the sources, if they're not giving the dead link, point to the STM32 Cube. And it's tough to figure out the difference between the ...
