HiIn the STM32L151RCT6 Datasheet (August 2017, DocID022799 Rev 13) it is specified that the PC0 to PC10 GPIO pins are 5V tolerant except the PC3, that should have a standard 3V3 IO structure. We have measured these GPIOs and have found that the PC3 h...
Hello!I'm using some of the string conversion functions, who's declarations are present in the "stdint.h" file. at present I'm using "strtol" and "strtod". According to the library "the value of the macro ERANGE is stored in errno, If the correct val...
We are seeing around 400mV of ULPI clock noise (60MHz) on the remaining DAC output with an STM32F427. The data sheet suggests to use the I/O compensation cell when using 100MHz outputs (like all the ULPI interface signals), but information about how ...
I am trying to flash a data to `EEPROM` of `STM32L051K8` with HAL library. This functions keeps returning `HAL_ERROR`. With debug i found the problem. In HAL Flash library before writing data to `EEPROM` it checks for error flags with `FLASH_WaitForL...
Hi,we have custom stm32f7 board with debugger connected and we are configuring UART RX in interrupt mode. In main function code is like below and uart rx interrupt is working fine for only once.uint8_t aRxBuffer[15];if(HAL_UART_Receive_IT(&UartHandle...
Hi all,I'm using uart5 of stm32f03rct6 with Std lib but it's not working. However, when i use cubemx with HAL, It works perfectly. Anyone can help me check my code :( USART_InitTypeDef USART_InitStructure; NVIC_InitTypeDef NVIC_InitStructure; GPIO_In...
Hello everybody,I try to implement work with the Stop1 mode but sadly my clock reinitialization routine seems to be not working correctly. When I put the MC in Stop1 mode it shall be woken up via LPTIM2 ISR on ARR match. So far this works. But since ...
IPC-A-610 revision G page 8-93 indicates that you can have a 30% void in your solder ball. We recently had a STM32F417IGH6 device over heat. Upon X-ray, we discovered that about 80% of the solder balls had voids near 30%.
