Hi everyone,I’m using an STM32L562 MCU and outputting LSE (32.768 kHz) to MCO for measurement.In LSE crystal mode, I see a large frequency deviation on the oscilloscope (much larger than expected ppm-level error).To rule out the crystal itself, I che...
Hey, I am using the STM32G0B0VET (16MHz HSE) with a virtual com port over USB. The virtual com port is working fine but as a backup I would love to be able to let the user reflash the device. I was thinking of using the DFU for this since then the u...
Hey guys, I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1...
Hi, I want to go to sleep/stop mode with STM32 and wake on interrupt. After last interrupt it should wait for 10sec and go back to sleep. But I see an edge case where interrupt could occur just before going to sleep/stop mode.How do I handle interrup...
Hi,i have new design that i am migrating to the STM32G071 and having issues with the SPI1 port PB3,PB4,PB5. Changing CPOL and or CPHA during init code do not seem to have any impact, when powered down and restarted.I am seeing 9 clock pulses when se...
If I am correct, the descriptions of - HRTIM_ADC2R - Bit 22 - HRTIM_ADC3R - Bit 19 - Bit 13 - HRTIM_ADC3R - Bit 22 - Bit 13 - Bit 10 - Bit 5 - Bit 4 - Bit 0are not correct in the RM.They all describe trigger event generation but th...
Dear ST Team,I am using an STM32H5 series microcontroller in my design and I am trying to understand the overall power consumption contributed by different MCU interfaces.So far, I have identified the following:The typical maximum current on VDD, in ...
Hi everyone,I am currently trying to measure the CPU temperature using the internal temperature sensor of an STM32F733.I am testing the device inside a climate chamber (oven) to verify the readings. I am fully aware that the datasheet states the sens...
Hello, i am using a stm32f103 mcu to provide rtc functionality. I am using a external crystal of 32768 hz for the rtc block.The crystal is rated at 6pf load. +/- 20ppm PN: QT1C-32.768KDZB-T Apart from this i have also implemented a external gps m...
Good Morning, I'm struggling with FDCAN Bus Recovery. The system we have to use consists of an STM32H753-based board and a 3rd party ECU, which is internally terminated via software. Our custom board is also terminated, resulting in the correct 60 ...
