Hello, I have some setup variables in my app which should retained while the power is switched off. Normally I would use the dedicated Backup RAM, but the board does not have backup battery, battery socket, not a battery connector. The Backup RAM is ...
I am currently using the STM32F446ZET6 chip, which comes with 16MB of off-chip SDRAM. I have been trying to run the program in the SDRAM, but have not been successful. I would appreciate any help.
In STM32F413VGT I2C3 support Fast Mode Plus(1MHz)?I cannot find documentation
Hi!I am experiencing some confusing behaviour on an STM32H743 series chip:I am running an injected ADC channel on ADC2, with trigger from the HRTIM. The HRTIM is triggering at 8000 Hz (200 MHz clock, prescaler div-2 and period = 12500). The ADC gener...
Hello We are working on a new project with STM32H723ZGT6. I want to control S70KL1283DPBHI020 DRAM with HYPERBUS communication using OSPI1. If you access 0X900000 memory to write and read data during the current operation, the data will not be read a...
Hello,In our application there is a STM32L073CZT3 component, we use timers and DMA to generate PWM that simulates a sine wave to start a motor.We encounter a problem with the microcontroller at high temperatures (about 80 degrees Celsius and above).T...
Hello. I'm having a problem with an STM32H503. I need to use the RTC, which is running on the internal 32kHz LSI clock. The clock configuration was created with CubeMX. When I check the RTC, I see that it has only advanced by 21 seconds in 60...
It's across 'U5, 'H5, 'H7 RMs, maybe more.How did I spot that? I was text-searching for 'NMI' ... :)JW
Hello ,I want to Access QSPI drivers in STM32H7A3VIH6. However in Cubemx there is only option of OCTOSPI1 and OCTASPI. My question is there way to use QSPI api directly like HAL_QSPI_Init instead of OSPi init?Or we have use OSPI only?Secondly i am us...
