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...
Dear STM32 Community,PFA for your reference.I am working with an STM32F765 on a customized board, using STM32CubeIDE version 1.17.0. I am facing an issue related to the RCC->CSR register and processor behavior.Issue with RCC->CSR: At the beginning of...
Is it OK to use these pins as current sinks for driving LEDs ?
I am using SPI2 and SPI3 with DMA1 to write and read to/from peripheral chips. This works fine most of the time. At the same time I am using the stop mode to save power. Now in some cases just after leaving the stop mode, the next DMA transfer does n...
These problems are probably related. I'm running STM32G473 at 160 MHz. I'm attempting to erase one page followed by 34 double-word writes to the same page. The code and the target are both in bank 1, but the problem occurs if I move the target to ...
My controller uses the STM32U575 chip. I followed the recommended design for the SMPS using the same inductor and XR7 capacitors as recommended in the reference design. I built up 4 boards, the first three boards worked properly without issue. After ...
Hi all,i am currently writing a program which is supposed to write data on an sd-card. This has worked until i changed my laptop (and cubeIDE version from 1.13 to 1.17) and until i added line 127 "HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_SET);"....
