Hi all,I want to use an external reference voltage on the Vref pin but this is a problem because the powerup of the main Vdda regulator is different of the reference voltage regulator (one starts before the other), in the worst case one can give 3.3V...
7x7 datasheet on page 27 says that VOS0 and VOS1 is disabled on STM32H7x7xIT3, but at the end of the note it also says that VOS1 is disabled on industrial temperature range, not specifying any package type.Is it disabled only on IT3 ending part numbe...
Hello there.I'm using a stm32F417VGT6 to perform an IAP in Keil IDE.in the bootloader, using the Bin file on a SD card, I read executed Binary program and write it on flash memory. then i use Jump_To_Application() to start the new app. Everything wo...
Hi!I have a SPI master that communicates in the following way:CS is setStart sending data in the following format - 2 bytes of "request"2 bytes of crc for the "request"x bytes to clock out the response from the slaveCS is releasedOn the slave side (S...
Does anyone has experiment project to erase and write to Parallel flash .We connected 16 Mega Bytes Parallel FLASH Chip and we are Using FMC interface on STM32H745XI . Following driver is being used but I could not find and example project to write t...
Due to dwindling stock levels we need to migrate from a F091 to a G0B1 series microcontroller. To keep compatibility for devices in field(for future firmware upgrades) I was wondering if it was possible to run the same code binary between the two mic...
Suggest a STM32H7 running from external clock source on HSE input. CSS is enabled. HSI is disabled due to power consumption issues.What happens if HSE fails?Will CSS start the HSI oscillator before switching to HSI clock source?Thanks for your help!
Hello,I couldn't find anything about this in reference manual:I have configured TIM8 to generate a DMA request on update. When I set TIM8, register EGR, bit UG to force an update while both the timer and DMA are not enabled, what happens to the gener...
