HiI'm trying to use an LP TIM to generate an interrupt after a time interval on an STM32U073CCT6. The interrupt will wake the processor from STOPMODE2.I haven't found any examples, and the STM32CUBE MX doesn't have a software-triggered single-shot op...
Hi, I'm trying to do an external loader according ST's MOOC and this forum https://community.st.com/t5/stm32-mcus-products/stm32h5-external-loader/td-p/601134.My code pass on all ST's tests of memory, but when I generate a stldr it does not read on c...
Been reading thru the F103 datasheet to try and figure out why my TinyUSB based code isn't working. The datasheet says.. "For mono-directional/single-buffer endpoints, a single register can be used to implement two distinct endpoints". The F103 has...
Hello community,I am new to stm32, and I need to read the temperature from the internal sensor of a stm32g4vet6.I am at the point where I have read many things and have discovered that not all stm32's internal temperature sensors must be used the sam...
There is this errata for STM32G0B12.2.10 Prefetch failure when branching across flash memory banksDescriptionIn rare cases, the code prefetch may fail upon branching and function calls across flash memory banks,regardless of the DUAL_BANK and nSWAP_B...
I am using a Nucleo-N657X0-Q board to prototype a data collection system that collects samples from an ADC connected to the SAI peripheral and places the results in RAM. If I use CPU AXI RAM0 as the destination this works correctly, but if I change t...
In my embedded software project, I need to write a bootloader. I wrote an application code for the bootloader and testing, and everything is fine so far, but the delay function in the application code is not working. I think the reason for this is th...
Hello ST experts,I have a weird experience with UART communication between two STM32G4 microcontrollers. MCU1 sends 10 bytes to MCU2 via UART. Both UARTS are configured with 9600 Baud rate with DMA in circular mode. The Problem arises when the MCU1 i...
Hello, I want to design a PCB with STM32H743VIT6 MCU. But I am not sure how can I choose crystal and capacitors properly. In STM32H743VIT6 datasheet there is one section about this topic;according to this information should I take the Cstray value as...
Hello,I have not found the maximum TRACECLK frequency of the STM32H725 in the documentation. It looks like it is generated by PLL1 with flexible division ratios and thus can attain values that are not realistic for I/Os (100 to 220 MHz for Speed 11 a...
