HAL_TIM_Base_Stop() and HAL_TIM_Base_Start() adds time? (trying to have a nanoseconds (100ns) control delay using a BASE TIMER)

Hello, I need to control signals in the order of nanoseconds magnitude (~ 100 ns). For this purpose, I have programmed a hardware timer in order to have an interrupt with 100 ns delay. I'm using a STM32F746VE microcontroller at 216 MHz. I'm using the...

Is it possible to write/read the state of GPIOs (HIGH/LOW) in parallel?

Hello, I'm working with a STM32F746 microcontroller and communicating with a external driver with a parallel bus of 16 bits of data and 4 bits of address. I set the data to the parallel bus doing a sequencial write of the GPIOS of the ports involved ...

Timer interconnections in RM0364 STM32F334 reference manual

In Table 24. Timer synchronization TIM2 is missing both as master and as slave.In Table 73. TIMx internal trigger connection the nonexistent TIM5 is listed instead of TIM15.Can you please forward it to the documentation team?

STMCUFinder stopped working on my system. Click on shortcut or directly running simply does nothing. Attempting to reinstall has a brief image flash, but then it is gone. Is this my crappy windows-10 system, or is it all windows 10 systems?

Are there STM32F4 and STM32L0 with automotive quality (AEC)?

I couldn't find any STM32 with automotive quality, so I would like to know if is there any?

UART in DMA cause MCU crash

hi every one i am trying to receive data with UART in DMA and Normal mode, but after about 10 times that I receive data correctly suddenly MCU stop working I checked every thing but I don't know what's wrong :sad_but_relieved_face: this is my Uart an...

What is the maximum Flash clock freqency of STM32H743?

Is it possible to drive the controller with 480 MHz and therefor the flash with 240 MHz?How many waitstates have to be set at 240 MHz?

STM32L5xx OctoSPI Read/Write to Xilinx FPGA Configuration Using SelectMAP

Hi. I want to use the OctoSPI to configure Xilinx FPGAs (e.g., Kintex-7) in the SelectMAP mode. Therefore I need 8 data bits, a chip select (CSn), a RD/nWR signal and a CLK to the FPGA. I know the OctoSPI is usually used for reading and writing to Q...
