MCO on/off modulation, STM32F334: What's the fastest way to switch MCO between off state and a clock source.

Is there a fast way to use MCO, mux it to an internal clock souce and use a timer to realize some kind of on/off modulation of the MCO pin?I muxed it to an internal source and tried switching the GPIO between input and output. This works fine but nee...

STM32F767 ADC Multi-Channel Interrupt Mode Read

Hi. I am trying to read 4 ADC Channels sequentially in interrupt mode: ADC2_IN7, ADC2_IN14, ADC2_IN15 and ADC2_IN8. However it only reads the last rank channel every time. Please help me understand what I'm doing wrong.Compiler:          IAR Workbenc...

STM32L4 I2S configuration not working with CS4344

Hello,I am trying to implement I2S protocol for my project with STM32L433RBT6. I should play short (up to 5 seconds) .wav stereo audio samples that are with 44.1 kHz sampling rate and 16 bit audio sample. The I2S line goes into the CS4344 DAC. Thus, ...

Hi all, Is there a straight way to port NUCLEO examples to different NUCLEO boards (ie not the one it has been tested with)?

I am developping a project around a F439 MCU, so I chose the NUCLEO-F439ZI to work with.I also ordered few NUCLEO expansion boards such as MEMS, TOF modules etc... Unfortunately, none of the project/examples provided with the expansion boards are pro...

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?
