RAM test method for X-CUBE-STL
Hi,I am reviewing the Safety Manual to utilize the Self-Test Library provided by ST, and I have questions about the RAM Test method.It is mentioned that STL provides RAM Test using the March C-algorithm, and its verified diagnostic coverage can satis...
HAL_Delay() Not Working Before OS Kernel Start.
Hi,I need to initialize a display by calling my function in main.c. This function uses the I2C4 channel and requires implementing some delays.Since it uses I2C4, it must be placed after the CubeMX Init functions, specifically in /* USER CODE 2 */. Do...
H7 USB devices Errata
Hello, I would like to get more info on Errata ES0392 Rev 13 - section 2.25.3:the errata states:I'm confused with the wording of this errata. Can someone from ST describe the meaning of this errata?I currently have USB0 connected to the USB Hub dire...
gRPC on STM32
Is there any effort underway to develop a package to support gRPC on embedded systems or more specifically STM32 ?
Resolved! HAL_UARTEx_ReceiveToIdle_DMA return HAL_ERROR when stm32's partner restart
Hello, ST experts HAL_UARTEx_ReceiveToIdle_DMA works well in our project, it can get idle interrupt or uart data stream interrupt. But when STM32's partner power down and up again, I think that means UART_RX line to STM32 goes low during this period,...
AZURE RTOS Support H7S3
I have started looking at using the Azure RTOS package for my project but see it has since become Eclipse RTOS? Is STM supporting this RTOS anymore as I see the H7S3 Azure RTOS package was only updated seven months ago whereas the H7 branch as update...
Atomic variable for scheduler question
I traditionally use a volatile type for my schedulers. Very simple like so volatile uint8_t myflag; uint8_t ticks; void Func(void){ ++ticks; if(!(ticks % 5)){ myflag = true; } } void User(void){ if(myflag) { myflag = false; //DO ...
Resolved! TIM still running in STOP
I am using TIM2 to create PWMs for LEDs. When I enter STOP mode I expect the PWM to stop. Yet it does not. From the manual TIM do not have wakeup capability from stop mode. So they should not be requesting the HSI to operate.What could possibly cause...
Resolved! 2 STM32F407 sending data to each other using DMA
I have 2 STM32F407 Discovery boards sending data back and forth to each other using usart2. Usart3 on one is just a monitor so I can see the output on a USB comm port. I'm using DMA on the receive for both and the HAL_UART_RxCpltCallback for both jus...
