I have built a sine wave to square wave circuit and now want to measure its frequency with the STM. I can see on the oscilloscope that the circuit works, however I can detect neither a rising nor a falling edge with the chip. It is not a problem with...
Hi,MCU- STM32H7I get a busfault exception when I read bank2 flash memory. I can read bank1 with no issues. From the flash register SR2, it shows as ECC double bit error. This is new pcb and I can flash the hexfile to bank1 successfully. Even a Jlink ...
Hello,readingHello,Pristine STM32L431 PA6 turned to hard output Pristine STM32L431 PA6 turned to hard outpuI wonder why there are no fuses to turn selected bootloader devices of? Cheers
Hello,I am trying to use UART with DMA with IDLE line for unkown length data reception and I am getting the following error:request for member 'NDTR' in something not a structure or union main.cI coded a couple of years ago a HAL_UART_RxCpltCallback(...
You don't initialize sFilterConfig to zero, so sFilterConfig.FilterMaskIdLow could be a random number upon POR.
I am using a Nucleo-F429ZI with FreeRtos and LWIP. I am having an issue with LWIP when I start with a disconnected Ethernet Cable and then when I connect it back when the firmware is running.I have a thread with the following code. 1 - The gnetif str...
Hello! I am experimenting with a STM32F030F4P6. When I connect it to STM32CubeProgrammer via bootoader (UART), there is an info saying the micro has 32Kb of flash, instead of the expected 16Kb for this part.Is it possible that this microcontroller re...
Hi Comunity, I am very new to STM and got some problems on serial UART. I can get data from my serial, but my problem is if the data received is less than the length of the array, the next data received doesn't overwrite the first data. How do I fix ...
Hello all, I've recently received a dev board for STM32G030F6 microcontroller and I wanted to make a simple USART test before continuing. I've started the project using STM32 CUBE MX initializing serial port and clock, also, I've retargeted printf as...
Fault handlers that work on M4 and M7's aren't being executed on an M33. The Usage Fault I'm creating (via an undefined instruction) appears to be escalated to a Hard Fault. The Core stops executing instructions before ever reaching a handler. Is ...
