I want to use the external clock mode 2 but it dose not work ,configure the PA12 that connect to TIM1-ETR AND make push button pull down to send pulses to that pin(PA12) to detect high edge and make up count to the variable "upCount" in the code ,i t...
I am trying to read capacitance and temperature from the AD7746 capacitance-to-digital converter, using STM32F103 and HAL I2C library (SDA and SCL pulled up with 2k and Vcc = 3.3 V). I did it before using AVR (using Codevision) and it worked fine, bu...
I am using STM32F103C8T6 with libopencm3 and FreeRTOS. Some programs I have can only flash once, even though the code function properly. The second time I flash it will say something like "unknown chip id! 0x3748. Failed to connect to target". I have...
When i used a bootloader to make user program run from QSPI Nor Flash in MemoryMappedMode, it worked well.But now i want to run user program from FMC SDRAM.So firstly i plan to initialized both QSPI Nor Flash(MemoryMappedMode) and FMC SDRAM,then copy...
Hi, my application needs to handle CAN message input, Updating the screen through UART, constant buffered LOG file writing to MicroSD card. I was wondering what kind of flow I could use?For CAN messages I could use interrupts and update variables (th...
The code below was implemented using a PsoC device. Maybe someone here can help me understand it and do the same in a STM32 device. AFAIK, the code is intended to build a quad buffer, but I don't understand how this is being implemented within a sin...
Hello, the STM32H7 (dual core) has two dedicated memory protection units. If I configure one MPU to make a memory region only accessable as readonly, does the memory protection unit from the other core inherit those configuration or is it bypassing ...
Hello! If I write less than 12KB #MSD works fine. If I write more than 12KB, Windows7 will ask me to format the drive. If the MSD is not reconnected to the PC, everything works fine. Everything breaks down if Ireconnect the device to the PC. Please t...
Hello,For STM32G4 Rev Y:Errata 2.7.3Wrong ADC result if conversion done late after calibration or previous conversion DescriptionThe result of an ADC conversion done more than 1 ms later than the previous ADC conversion or ADC calibration might be in...
