We have run into a problem where a new run of boards with STM32F429ZIT MCU's have been losing a byte (always loses a single byte which seems odd) from the UART communications that are sent to DMA.We send packets of UART data to the MCU and the data i...
I've bought some new STM32F777BIT devices with datecode 145 marked with a new revision code 1.All my older STM32F777 was marked with revision Z and current errata sheet ES0334 Rev 7 mentions only revisions A and Z.What are the differences between rev...
The only part I am not familiar with is all the registers, is there something that may have been corrupted, and I should set back to some values ???
Hi everyone,I am having issues getting One Shot Mode enable when using the TIM15. I am currently using the STM32H743ZI as the MCU.When setting the OPM bit in the TIM15_CR1 register the CEN bit in same register no longer can be enabled for whatever re...
Hi,I would like to have SPI2_CLK signal available on the CN2 connector (STMod+ interface) on the STWINKT1B eval board. Based on the schematic, looks like one can activate SPI2_CLK signal on STMOD4 via the 3-4SEL pin on the STG3692 digital switch. But...
when performed NVM operations (write on page and erase page), i lost some recieved bytes in my LPUART Rx line.when i uncomment the part of writing on the nvm, the lpuart works fine.can any one please tell me if there is a way to use this modules toge...
I was using stm32f4 on my project but now I want to use the h7 products. I am reading referance manual and watching some videos about the arm cortex m7, but I didnt understand completely about the CPU things. How can I learn the most basic way to und...
Hello i am trying to use I2C interrupt communication between my STM32L4 and an NFC module, however when i try to visualize the signal i have nthg. I feel like i have forgotten sth, but i can't figure out what is it. Can you please help?This is what i...
G071 is different from F429. When F4 is idle, MOSI is high level and MISO is low level. However, when G0 is idle, MOSI and MISO are both low level, which seem to be incompatible with my external device
Hello team, please find below my code for receiving the dat from the tera term and after flashing the code could see the rx_data is properly initialized and after pressing the resume option in the debugging environment the first byte of the rx_data i...
