Hello,What is the best way to multiplex an output pin to 12 output signals? I currently have 1 output sourcing 3.3v through a 1k resistor which works well, but need it multiplexed to 12 identical outputs. I see the STM32F373 has a max rating of 15m...
Hello everybody! I have a sine-wave array, that I throw to the DAC, triggering it by TIM6. When the TIM6 interrupt routine is responsible for supplying samples - everything works fine, but when I try to use DMA nothing works. The DMA keeps spitting t...
Hi, I want to make communication between stm32h563zit6(Nucleo-H563zi) via USB communication, i have tried configuring various UART/USARTS but not able not make communication.I had verified it by sending some data from stm32 ,and tried to see it on ...
我用板子A：STM32H743VIT6，HAL库开发，版本v1.9.0HSE=20M，主频480M串口1使能，DMA发送，IDLE+DMA接收数据。发送使用1ms定时器进行DMA串口发送，发送间隔1ms，发送数据长度18字节。板子B：STM32F405RGT6，HAL库开发，版本v1.27.0HSE=8M，主频168M串口2使能，DMA发送，IDLE+DMA接收数据。数据发送使用1ms定时器，10ms间隔通过DMA发送数据，发送数据长度18字节。连线板子A的Tx-板子B的Rx。板子A的Rx-板子...
Hello,I am new to dual core controllers and I had a question on how the internal ST bootloader works for STM32H755, till now I have used STM32F4 and STM32F7 series with single core and i have loaded User code using UART and ST Flash Loader, as I unde...
Is it possible to switch VREFBUF clock off after configuration for power save? So the clock is off and the buffer is providing Vref.In DS there is no mention about it (e.g OPAMP has this note).
Hi All,I’m new to using the STM32H563 solution. To send SPI data using DMA, I referred to the sample code from the SPI DMA sample of the H533RE project.I'm not sure when exactly the SPI is start to transfer the data by DMA.The following is a part of ...
On my custom board based on the STM32G071CBT6 mcu I use ADC multichannel DMA conversions, DMA continuous requests, triggered by TIMER2 out event and driven with HAL library (STM32G0 firmware package V1.6.2). I get ADC conversion results by the conver...
Hello,I have a question regarding doing a firmware update via the USART-pins and IO-Link.Would it be possible to use a IO-link master module to sent an update to the L6362A which translates it to 3.3V UART for the STM32G0B1KEU6 we are using in our cu...
We have a new revision that has a significant population of boards with this intermittent power issue. steps to reproducepress power buttonpower applied to the MCU the MCU only prints a single debug message, then haltspress reset: device works normal...
