A question about this sentence of STM32H7 reference manual:Receive-only mode: COMM[1:0]=10In master mode, the MOSI output is disabled and may be used as GPIO. The clocksignal is generated continuously as long as the SPI is enabled and the CSTART bit ...
On page 252, "Vdda = .3 V" is written twice. With this the calculated value is incorrect. The correct value is Vdda = 3.3 Vplease fix your documentation
I think I am missing something obvious about a difference between channels 2&3 vs channel 4 in the TIM8 after staring at this for some hours now...I am using the STM32H750 discovery board, and created a project in CubeMX which configures PI2, PB14 an...
Software download issueHi, I have met the same issue like this. Should I also wait an hour until this package been prepared?
Hello,I would like to find out if it is possible to use STMG070 USART break detection circuit in non-LIN mode.Specifically, I have an application where I use a UART configured for high-speed data transfer (over a megabit) in DMA receive mode. Rather...
The data sheet isn't specific, apart from one diagram Figure 13 that shows IO's box with an arrow from VDD that then connects to a level shifter to the core domain.Please advise. A real handy feature would be to alternative voltage IO for the SPI's...

Hi, i'm using my STM32F7 nucleo 144 and i'm learning about timer encoder mode and i follow the example in the datasheet but when i check the CNT register it oscillates in the same values and if i use the A0-A1 pins the encoder works bad, can somebody...
Hello everyone, I'm trying to build a sensor device that uses stm32l452re as MCU, I need to save my data to sd card using sdmmc features to access it. i using 4bit mode and clock divide 128, but unfortunately, my sd card sometimes corrupted and i nee...
