Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
here i generate pulse using pwm generation.. where i need to stop at n th pulse.. so i use RCR register to stop it..where my mcu handle only 8 bit data to the RCR register.. so i split the data into array "RCR_Data" and stores as source destinationi ...
STM32H7S78-DKlinker error occured.estimated minimum size of 0x1'3456 bytes ...Using IAR EWARM 9.60.2.What should I do?
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...
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...
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...
Is there any effort underway to develop a package to support gRPC on embedded systems or more specifically STM32 ?
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,...
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 ...
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...
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...
