Hi all,I am working on a STM32F103VEtx MCU. In my firmware I have redirected the printf function to a UART for debugging purposes. When I start running the code, the printf function causes the hard fault handler to hit. Please see the call stack att...
I know that it's straightforward to just try, but currently I don't have the board at hand...This doubt has arisen while I was unit testing some corner cases of my timer functions on the development machine (with mocks and so on).For the common case,...
Hello everyone, I've made a code within my STM32f405 MCU that writes SD 4 bits wide bus onto an SD card. I'm making a program where "HAL_CAN_RxFifo0MsgPendingCallback" fills a "uint32_t dataCANID[14339]" array and increments a counter. This counter v...
DMA requests are still generated if the CCR is outside the auto-reload rangeThe DMA request is is generated when CNT reaches 0 rather than being disabled.Processor is a STM32H750is this a bug or a feature - it should be documented anyway
Problem 1) current draw does not change after entering sleep mode.Problem 2) not sure if program should resume where it stopped or from the beginning of main. Also any difference between waking by NRST or by A0 set to PWR_WKUP0?Mcu is 'H747 operati...

I want to know the current level of the channel-input filter's output, marked as TIxF on the diagrams and in narrative.I know I could read the respective pin, but that's not the same - it misses the filtering aspect, i.e. a single read might inadvert...
Hi Community,I am working on deveoping applications on STM32 IoT Doscovery kit. I am interested in the lowe power design aspects as far as the sensor reading is concerned. This is my first time working with sleep modes / reducing power consumption. C...
Hi guys, I would like to connect two different MCU to each other through I2C. One MCU would be the master, and the other one the slave. How can I find the I2C addresses of these devices ?I found the device ID in the reference manuals : 0x411 for STM3...
I am working in small startup in Bangalore. I had designed the board using the STM32F103R8T6 controller now i am facing oscillator issue, oscillator is not working as i expected. thereafter i googled it for oscillator design guide and i found AN2867....
