In reading the manuals and datasheets, it seems like it should be possible to simultaneously use all 3 channels (DAC1 Channel 1, DAC1 Channel 2, and DAC2 Channel 1) of the onboard DACs at once, emitting separate values on each. However, no matter wha...
Hello,I am trying to manage data transfer between the 2 core of the STM32H747.My problem is all hardware semaphore are locked just at the initialisation phase ( MASTERID 0X03 , Core M7) After Hal_Init(); & SystemClock_Config(); all is free.after __HA...
Hi,I am considering upgrade from STM32F4 series to STM32F7 or STM32H7(single core) series. However, the H7 embedded memory is not enough for the requirement. I would like to run simple RTOS scheduler. So there is need for external memory.-QuadSPI int...
I'm having an issue configuring the OCTOSPI for accessing an external HyperRAM (Cypress S27KL0643) connected to OCTOSPI1.My basic issue is that the STM32 doesn't provide a chip select or clock when I attempt to access the chip.I'm suspect I'm misconf...
Can i replace the stm32f427vit6 with the f429vit6, f437vit6 or 439vit6 without changing code, and are they completely pin compatible?
I am running CAN1 on a STM32F415 processor to communicate with an ECU and several other 415's on the bus. I have the SCE handler set up to store last error codes (LEC). I don't seem to be having any problems with the receive but the transmit side is ...
Hello everyone,For over a year I've been involved in a project using the STM32H753VIT microcontroller. The firmware has been in development for quite a while and has subsequently been growing.Currently, the compiled binary is at the point where it is...
I think I've set up everything sensibly via STM32CubeMX to get HAL control of the LSE, but the external oscillator appears to be not operable. In particular, there is essentially no voltage on the 32kHz crystal pins, so of course it will not oscillat...
I've been a month trying to get connected to Truphone and have gotten nowhere. I have not found any AT command documentation on this site, where is it?So many questions but running out of time...
Please help me with operation of the FMC module in STM32F407VE. It is necessary to connect external RAM memory; since FMC module in this microcontroller uses the address bus and data bus in muxed mode, its need to demultiplex this signals. For this p...
