Hey guys.I need to enable/disable the line 14 of the EXTI interrupts multiple times, using HALDo i just use the HAL_NVIC_DisableIRQ HAL_NVIC_EnableIRQ ( and HAL_NVIC_SetPriority whenever i re-enable the line?), providing the correct handle to the a...

Hello guys. I'm trying to design a custom pcb that uses an STM32h7a3zit mcu and one of the most confusing parts is clock configuration. I will mainly use the hs usb interface. I've searched a couple of online sources and from what i could find is tha...

Hey guys.I'm trying to build a custom Pcb that doesn't include the onboard st-link and be able to program it though the STDC14 connector.I found some schematics about the nucleo H7A3ZI-Q board, but i was confused about a couple of things.1) The STDC1...

Hey guys. I'm trying to learn how to use the stlink programmers and program a nucleo board, without the use of the onboard programmer.I've successfully flashed the board by using the MIPI10 interface and the stlink. The thing is that i we want to mak...

Hey guys. I'm trying to use the SPI1 interface on the aforementioned nuncleo board, but no luck whatsoever.I want to transmit 2 3Byte commands to a dac device. The first one is 48,0,0 and the second one is 55,255,255. My code is: uint8_t msg_Tec[3]...

So if got this rightT_SWDIO should go from the stlink vset to pin PA13 on the processor,T_SWCLK should go from the stlink vset to pin PA14 on the processor,T_VCC should go from the processor's power source to the stlink,T_NRST should go from the s...

1) Do i just need to connect T_SWDIO and T_SWCLK to their respective pins and provide enough power to the board, so that i can flash the program, or do i need to do something else too?2) Sorry, i was referring to it as serial wire interface.3) SO the...

I tried something like thiswhile(CDC_Transmit_HS(messageOk,sizeof(messageOk))!=USBD_OK) { }but it seems that the message is transmitted, even if the port is not open. Is there a similar approach to this ? The while loop should end only if the data a...

Is it safe to use functions like spi_transfer, or further cdc transfers inside the callback, or will the program hang ?I tried doing something like this inside the callback function :static volatile uint8_t newDataAvailable=0; static uint8_t received...

I'm currently using the usart interface, which is connected to the onboard st-link.What libraries do ia have to include in order to use the aforementioned status ?
