I am trying to create a repeating trigger to start an SPI transfer to read 12 x 16 bit values from an external ADC.I have configured the SPI with a Rx DMA to receive the data and have created a timer to trigger a second DMA to write to the SPI->CR1 r...
I have a STM32F405 with a coin cell on VBAT and I haven't been able to get the Backup SRAM or RTC to preserve contents when removing main power. The same code works fine on another board that has a STM32F407. //Works on STM32F407 - Fails on STM32F40...
Hello,Recently I spent some time solving the problem of incorrect CPU operation. After generating the project (completely basic, only TIM6 set as TimeSource for HAL), the program diverged when trying to enter the interrupt from TIM6 (I'm guessing). K...
Hi,Does anyone know which bootloader to use for this damn board (STM32F407VEt6). I have tested several of them but it is still not recognized by Win10Thank you in advance
Hello Community, I am currently working with a stm32f302rc microcontroller, I need to configure my ADC2 to measure the reference voltage of operating amplifier 2 (Vrefopamp2) (it is internally connected to channel 17 of the ADC).I need this to check ...
Some STM32's have VDD and VDDUSB. Setting VDD to 1.8V and VDDUSB to 3.3V, the GPIOs work at 1.8 V, and USB keeps working (the USB transceiver needs 3.3V). Each time, there is a note that VDDUSB has to be the last power supply to be active when poweri...
We are using a the Microcontroller for one of our products , we are using two UARTS for communication , however when both the UARTS are enabled we are facing some difficulties in the communication, can anybody help in this ?Attached is the main file ...
Hello,I tried copying BSP and Utils folders from "Repository/STM32Cube_FW_F4_V1.27.1" into my project, I included them in "Paths and symbols" project settings too.When trying to build the code, I encountered a lot of compiler errors of symbols not be...
Hi TeamI am working on the ST provided package with TF-M Example and working on adding the smart card interface at uart3(without using cube mx setup). I have a working code with smart code with TF-M Structure(GTZC enabled) and using Cube MX. I used t...
We've developed an oceanographic profiling float that runs unattended at sea for as long as the batteries last. In normal operation, the float sits on the ocean bottom, wakes up every 6 hours and ascends to the surface acquiring data as it goes up. W...
