Hi, this is new for me. im working with a project that includes an STM32U575RIT6Q controlling a device through the SPI3 interface at 40MHz with 8 bits per word, SPI mode 0, and the GPIO change speed at very high. The microcontroller is running at 160...
Hi STM community,I had a recent issue arise and I'm not too sure how to resolve it. I have been learning to use STM32CubeMX as well as the IDE, currently I am trying integrate a NN onto an STM32f746G-Disco and I keep getting promoted with this:My stm...
Hello,I’m trying to use an STM32F411RE microcontroller as an ISO7816 smartcard slave rather than a reader (i.e., to emulate an actual smartcard). In this scenario, the clock would come from an external source, and the MCU would respond with an ATR an...
HII'm trying to reduce the noise of a high RPM motor with the library below. - STM32Cube function pack for acoustic echo cancellation - https://www.st.com/en/embedded-software/fp-aud-aec1.html The subject is to reduce the noise of a high RPM motor wi...
Hello,I'm currently working on a project that includes integrating a real-time operating system into the STM32F217VGT6. I created a project for the STM32F217VGT6 MCU with FreeRTOS as the middleware in the STM32CubeIDE v1.13.0. The code generated in '...
Hello to all,We encountered a strange behaviour of the ST32F7xx jpeg encoder.We feed the encoder with RGB data like 0xFF0000 which is pure red.However the resulting jgp image is green.Then we gradually reduced the intensity of red like 0xFE0000, 0xFD...
Hello,I hope everyone are doing well!I have implemented MQTT protocol in an STM32H7 microcontroller that is attached on a display. For that reason I have use the subscribe method in order to receive payloads from 6 different topics, which two of them...
Looking through the HAL for the dual core processors, its pretty easy to stop a core from itself by calling HAL_PWREx_EnterSTOPMode() or similar. However, I don't see an obvious route to, for example, stop the M4 core from code which is running in th...
Dear all,i am facing very strange problem with sprintf function .i am using sprintf function in 1ms timer interrupt routine and it works fine. for example. void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { sprintf(uDisMsg, "%.1f", 258.6...
Hi I am having the same problem as described in the old post down below.... is there a way to activate the link inside to see the fix? I am also using the external ULPI PHY, but when the USBD_Connect function executes, pin PB14 is lost. This is becas...
