Hello Everyone, So, I am trying to configure the SPI1 to work with DMA so I can fill in a buffer from my sensor for every occurring interrupt, so when the buffer is full and I can send it to my client server. I used CubeMX to configure SPI1 and DMA2 ...
How to use STM32F100 to measure a sinwave's frequency by input cature mode of TIM3 ? I would like to measure sinewaves of three frequency, 39Khz�?40Khz and 41Khz.Voltage level (0V-3V)The 39khz period is 25.64us.The 40khz period is 25us.The 41khz pe...
I'm having a lot of trouble finding documentation. This board sold by ST exposes a connector that is intended to house an ESP8266 WiFi device. But the ST documentation says nothing about how that connector is wired on the board. I assume it's tied to...
Hello ! I really need your help , im working on a project and its a game of luck , random numbers will appear on 4 x 7 Segments , so i must multiplex , i understood the principe but i can't reach some good results , i don't know why ...only the commo...
Hello everyone,I am working on following application.I need to measure average of samples read by ADC1 (Differential mode). It starts reading values when interrupt from pin PC13 (Rising edge) is detected. It stops reading values and display the resul...
Can anyone give me an example for an I2C-Slave at STM32F401RE?The delivered example I didnt understand...I can send Text from Mater to Slave Board, but then i dont know how to go further...I'm sitting hours at this...thanks,Christoph
Hello there!I'm trying to build an external loader for STM32H7, so I can use a NOR FLASH in XiP mode, but following the AN and the examples in CubeProgrammer folder, I'm getting the message:STM32CubeProgrammer API v1.4.0External loader : SectorErase ...
Hi all!I am using STM32F427 with HAL. I have to communicate with other devices using communication protocol over RS-232 interface (USART). The protocol is using 7 data bits, odd parity. I am struggling to make it work. There is a setting for WordLeng...
I have a custom board based on STM32H753. It has SDRAM, SD card slot, a couple of I2C peripherals, some GPIOs going to LEDs and a handful more that go to CPLDs which interface to another part of the system.I am not using generated HAL code or CubeMX ...
Still struggling with this so hopefully somebody can help me. As far as I can work out the STM32(H7s if it matters) need three pins (TCK, TMS & NRST) plus a common ground to be programmed from another MCU. I can't dedicate three pins on the master ...
