Hello community,It is possible that an interrupt will be nested over itsef?I mean, I have one interrupt EXTI0_IRQHandler() and inside the interrupt I am waiting an event that requires the execution of the same interrupt. I read the PM0214 and it is s...
Hi,I am using STM32F746G_DISCOVERY board.In the QSPI_PreInitConfig example, how to put const array data to QSPI flash? I try to declare as follows, but cannot pass compiler. error: 'img2' causes a section type conflict with 'GpioToggle'. I notice th...
Hi Everybody,I'm using a nucleo board with STM32L412KB and I try to learn how to use the STOP mode. I want to put the micro in STOP mode and reactivate it whit a command via USART. I put the UASART baudrate at 115200 and use the HSI clock. (see clock...
Video;:https://streamable.com/pw1c68I tried internal and external clocks, the result did not change.
I am using the IN0 and IN1 channel of the ADC1 peripheral. 4k7 potentiometer is connected to my inputs. 1 When I turn the pot of the channel, I see a very good reading. When I turn the pot of 2 channels, it becomes 0 between 0 and 1023 even though I ...
Hi all,I'm trying to implement a class that should allow me to use the USART with the DMA. It's a learning project in which I'm trying to learn how to retrieve the correct information from the datasheet and the reference manual. I'm reading the refer...
I am working with stm32f7-custom board using 8inch touch screen(microe3902) & FT5426 capacitive touch controller FT5426 not respond properly
Do you've any idea for STM32F410RBT6 ic availablity? because we are suffer to get the IC's
I actually wrote a CAN routine to send commands from STM32MCU to some ECUs, all of which are connected to a single Bus. I noticed that during transmission If I temporarily remove the STM32 MCU from the CAN bus and put it back into the bus. It won't s...
I am new to STM32. I am porting my code from ATMega128 to STM32 for faster thru put . I have to connect W5500 to STM32F103 on SPI2. To test my understanding of SPI on STM32 after compiling , a small test code in while loop. SPI_Write(S0_CR,CR_CLOSE)...
