STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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%.
Hiall,Working with the OpAmp4, in the CubeIDE, it seems like it is poossible to connect the DAC_OUT1 to INP, internally. I tested in some ways, and its appears the signal form DAC_OUT1 dont reach INP of the OpAmp.Reading the RM0316, page 112, the tab...
Hi, I’m trying to establish TLS communication with my local mosquitto broker.The handshake always fails, the broker does not accept the hello client and I cannot understand why …Below the decoded messages that pass over the network.Messages are captu...
I have found something which is unexpected behaviour / errata in the STM32G071's DAC. In summary, once the DAC channel is enabled (in this case I'm using CH2) then the pin cannot be used as a normal GPIO output, even if the DAC's output buffer is dis...
