Are there any guides or tips on making an STM32 MCU last in a high temperature (~150°C) environment? Specific voltage or clock speed tweaks?The MCU would sleep most of the time, but now and then take and store some measurements.Would certain families...
I sample a 1000Hz periodic signal twice each period. At 50us after the start of the period for samples A and after 850us for samples B with a single ADC and a single channel. I trigger the ADC with a delayed PWM (Combined PWM1 on a G431) and the res...
Currently I'm able to run ADC1 and ADC2 in interleaved mode using seperate (on purpose) DMA channels for ADC1 and ADC2. To start I'm using: SET_BIT(hadc2.Instance->CFGR, ADC_CFGR_DMAEN); //Enable DMA transfer for ADC slave (ADC12_CCR.MDMA = 0b00 -> ...
Dear community,I'm currently working on a student project where we need to analyze the performance of the FMAC unit of the STM32G4. My idea is to implement an FIR filter and measure how many clock cycles the FMAC operation takes to filter a predefine...
Hello,Can anyone suggest whether or not I need to connect external capacitors to the VREF+ pin if I plan to use VREF only for the onboard DAC?Could this be a hardware problem?STM32G431CBT6. The problem is that on the oscillogram I see oscillations wi...
Hi,We are using STM32G473CEU3 in our designWe have a situation that when MCU is powered off, 3.3V appears on one of the IO pins from an external circuit with 2mA of sourcing. Will this damage the MCU or is it ok?
I had to calculate the sine wave signal in function generator voltage and the adc value I had implemented while changing frequency the voltage and adc values are constant I had stucked in this
Currently, I try to use an quadrature encoder connected on pins PC12, PC11 and PC10. All these pins have in common that they all can use Timer 8, for channels CHN1, CHN2 and CHN3. When I try to configure Timer 8 in Encoder mode; I can't select the CH...
hi，for our project，we used firmware package was STM32CubeG4 Firmware Package V1.6.0 / 05-June-2024.IDE: MDK 5.39MCU: STM32G473MET6 EEPROM: 24LC256we already check the page write opreation, ensure the boundaries and size of each write (less than or eq...
I set the X1 buffer size to 18 and preloaded it with 18 values. HAL_FMAC_FilterPreload_DMA returned 0 indicating success.Some cycles after that, I should see X1FULL go high when the DMA transfers complete. I'm not seeing this. Instead, X1FULL stays l...
