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...
Hello!I'm new here, so please and sorry for the request but thoroughly explain your answers thankyou.I have an STM32F103C8T6 Board and a ST-Link V2. I can send sketches from the arduino IDE just fine using ST-Link, but neither UART(Serial) nor USB(ST...
Hello.Sorry for my bad English:) I am trying to read flag on the device MLX90614. datasaheet Page 23. The format of a SMBus transaction which reads flags is: i.e i must send start->slave address->command and right away without send repeat start recei...
On the UM1725, DocID025834 Rev 5, par 57.2.1, pag. 766 A function called HAL_SAI_FlushRxFifo() is contemplated among the "SAI HAL driver additional function list".On the hal driver, this function is declared on the comments but it is not implemented....
Using the CubeMX generated code, the timer interrupt goes to HAL_TIM_IRQHandler(TIM_HandleTypeDef *htim) where the source of the interrupt is checked. It then calls the correct callback function depending on the source. Problem is that both the OC an...
Hi ST support team,I am using STM32L4 for a developing project. And I recently found that the GPIOs under DFU mode are set very randomly.That means, for most of the boards we produced, for a specific pin, it is set as LOW, but some are set as HIGH. ...
Is the ordering of simultaneous ADC interrupts deterministic and how could I find the ordering? I am triggering two ADC sample and converts simultaneously from a single timer (gave up on using "multi ADC mode" ) and need to know when the second inter...
Hi there - does anyone know if the STM32L162 is able to run Amazon freeRTOS kernel?Thank you!Philipp
Hi I like to use my small mcu system (stm32f401 with 4bit SDIO and USB-Device) in the follow way:If USB is plugged in -> the system should behave like a msd on a windows machine.If USB is not plugged in -> the system should read the files from the sd...
There is a bug to set baud-rate of uart9.If I set it to 9600, it works as 19200.I think it is a problem of driver code.The UART9 and UART10 should use PCLK2 but the code uses PLCK1.Please check below.My environment:Win 10. 1809STM32CubxMX version 5.2...
The title pretty much says it all, to me it seems to be impossible to get the CAN periephal running with the HAL codes.loopback works all night, next it crashes to first message.i can sniff my car's canbus, then i cant.is there any alternative availa...
