Hello! I'm creating a basic UART project (using an STM32WB55 development board) to communicate with an external piece of hardware where I'm trying to send 9 bytes of data across and receive data back with an interrupt. It would appear I AM receivin...

Hello everyone!I'm trying to setup a very basic application and currently have my LPUART Tx and Rx pins tied together. I'm able to run the following code without any issues (well, this is the core of the code with all the initializations stripped out...

I tried importing a project using STM32CubeIDE V1.4 and got the following error: I tried doing package updates and everything I could think of but I wasn't able to figure out how to resolve this (tried googling/forum searching it but no luck). Anywa...

I went ahead and went back through the datasheet and came across the ORE flag, which I remembered I had cleared in another application I had (as well as the NE flag, for whatever reason). I added them both and the code appears to send the data across...

Ok, looks like I'm back with more info!I went ahead and hooked up a scope and, as I suspected, the data was being sent out and received correctly (which is a fun bit of news!). Unfortunately, the microcontroller seems to be catching the interrupt bu...

Yeah, I just have a few functions that need to send 9 and a few that need to send 10, so I setup a global array of 10. I did specify that both Tx and Rx are sending and receiving 9 bytes so, assuming I'm not trying to send sizeof(UART_txBuffer), I t...

Heh, yeah, I was actually kinda expecting this and should've just uploaded everything initially. I actually did have the inits in there, it's just not in the code above as I reduced it to make it easier to read (at the cost of having all the pertine...

Yeah, that's actually one of the things I had tried as well but it didn't seem to work for me either, oddly enough (had seen it in someone else's example project).Here's what I tried: uint8_t temp_Char = 0x01; HAL_UART_Receive_IT(&hlpuart1, &temp_Ch...

Troubleshooting UART comms issue (I think I'm really close but I'm missing something obvious)

Really basic question about HAL_USART_RxCpltCallback function

Anyone know how to resolve a "fail to get required stm32cube firmware package" error when importing a new project?
