Hi,we are having difficulties in order to find solution for STM32H7 Nucleo Board (NUCLEO-H743ZI2). When we are trying only toggle a pin ( interrupts are closed --> 480MHz)freq is not passing 20MHz. When i check ref documents GPIO section, it says “F...
Hello,I successfully sent data from the STM32H747 to the computer using USART1 via usb. Nonetheless, I can't find any solution to send data from the computer to the STM32. Any ideas on what communication protocol and medium I could use ?Data are comp...
Updating to CubeIDE 1.14.1 I have seen that I can choose some new STM32H7xx MCU's ( especialy the STM32H725, STM32H735 and STM32H730 ). They are very interresting for me ( 3. CAN interface and 2x OCTOSPI with hyperflash support ). Is there any roadma...
I am getting so much noise on analog pin without connecting any analog signal. I also tried by changing analog pin but still i am getting so much of noise in analog pin. I am calculating analog value for 50 Hz signal. Is there any way to calibrate S...
I have found a few tutorials about implementing a vcom port with STM32, and I could successfully programs (well, let's not exagerate let's say I merely generated programs) working for discovery F407 and F469. I could send a constant string that I rec...
In the datasheet https://nl.mouser.com/datasheet/2/389/dm00440565-1799229.pdfis stated that the uart and the SPI are part of two different alternate functions. The error message and the code will also uploaded if needed.
Hi, is there a way to slow down the DMA speed for DAC? I am using stm32F72x, and I am trying to generate a customize PWM wave from using DMA+DAC.
I get this error in several different codes. Including led blink also.
I am using an STM32L476RG and using I2C-1 and I2C-3 to connect to two different sensors. Both I2Cs have identical waveforms on the SCL and SDA lines when observed with an oscilloscope. This suggested a short to me, but the short is definitely not on ...
How can I get a snapshot from the TTL camera that is wired to the STM32F4 by pushing the user/any button? After the image has been taken, it should be transferred to a mobile device via Bluetooth. I'm newbie and don't know where to start. Looked up ...
