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 ...
Hi there,I have been struggling with the PSRAM. I bought the STM32H7S78 board to pick up the know-how to understand how I should configure the PSRAM at XSPI1 via the EXT MEM manager at my own board. My clock speed is 200MHZ XSPI. PSRAM MPN: APS6408L-...
I have a new board design that interfaces an STM32L4A6 with a uSD card using 1.8V I/O. The SD Card is powered by 3.3V and supports the LVS mode of SD. The STM32L4 does not seem take account the SD specification 6.0. There is no auto detection mecanis...
Is there a comprehensive single documentation source of the Flash layout for say, an STM32H563?The documentation I find is very opaque. Questions I have at present (From a non secure perspective):1. Where is OBK located? (0x0BF0000 to 0x0BF9FFFF ???...
