Hi there,I have an FTDI USB-Serial cable connected to a NUCLEO F413ZH. I am running the UART_Printf example from STM32CUBE_FW_F4_V1.18.0 in Keil but am not getting any output in my serial terminal (PuTTy).I have connected the USB-Serial cable to the ...
Hi,I want to ensure SPI communication between STM32F407VG board and Eval-STPM34 metrology board , i am trying to read just a register of the Eval-STPM34 but i always fail , i used these pins to ensure the SPI communication :STM32 -----> EVAL-STPM34MO...
Hello everyone,I am working on RTC of STM32F042C6. But I have a calibration problem. This is my measurement mechanism:For example: I’m measuring a +23,2 ppm error. I’m writing the value 24 (+23,2 ppm / 0,954 = 24 clocks) for the CALM bits of the CALR...
I cannot find any schematics, what kind of crystal. I want to connect 20 MHz. It seems it is as high as it can go. The datasheet does not say exactly what o connect.Some of the STM have two pins to connect extearnal oscillator but this one has just o...
Hello, dear collegues!Please help me with I2C!I use I2C to transfer data between 2 controllers: STM32F051C8T6 and STM32F100RB.When I use laboratory power supply, it works without some problems. But when I use external power supply based on the pulse ...
Trying to send over USART1 at 19200 bit/s.USART is resting in receive mode (RE==1, TE==0).After switching to transmit mode (TE:=1, RE:=0), we observe a ~500 us delay between storing and transmitting of first character. Subsequent chars are transmitt...
I'm developing a bootloader for an STM32L0 MCU that will jump to one of two or more application partitions in flash. I'm using IAR 8.22.2.To make the application binaries position-independent, I've compiled them with the -ropi option. I've also modif...
Hello,I would like to freeze the functionality of the IWDG while the microcontroller is in STOP mode, because I want stop time greater than 32 seconds. I read the documentation and I built the following code: FLASH_OBProgramInitTypeDef pOBInit; pOB...
I am working on stm32f103c8 using its SPI 2peripheral to communicate to slave device which is also stm32f103c8 using SPL library . master unable to transmit 8 bit data stuck on txe flage which is remain reset mode.
I'm involved in the developmentof a project where I will use STM MCU that has the capability of multiprocessor communication ("Multiprocessor communication").This type of communication allows multiple USARTs to be connected on the same network and on...
