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...
Hello,I am trying to output the reference voltage for the DAC in a Nucleo L4R5ZI, I am doing so with the Vref Buffer. I am using STM32CubeIDE.After creating a default project I just disabled all the communication I wasn't going to need and I configur...
Hi I am working on getting and processing raw serial data on a STM32F303RT8 MCU. The interrupt is firing but I am not able to properly read data from the Serial interface.Every time the ISR fires, the value of "sr" is 216 except for the first time w...
I'm working on a STM32L072, and I tried to configure the PVD to rising an IT when the supply voltage is below 2.7V.It appears that the IT is always rise even the voltage is always above 3V. __HAL_RCC_PWR_CLK_ENABLE(); __HAL_PWR_VOLTAGESCALING_...
I want to write my own custom bootloader program so I want to communicate with MCU using SWD data & clk pins but how can I use this pins?
Hi I use UART very rarely and I would like to disable gpio:void Disable_Not_Used_Pins(void) { /* Disable UART pins*/ GPIO_InitTypeDef GPIO_InitStruct = {0}; GPIO_InitStruct.Pin = GPIO_PIN_2|GPIO_PIN_3; GPIO_InitStruct.Mode = GPIO_MODE_ANALOG; GP...
Hello,I am using ST-LINK/V2 (STM32 Nucleo-64) to debug a custom board, which the custom board use STM32F105VC MCU.The HW connections are as follow: SWD, Custom Board3.3V, 3.3VSWCLK, PA14GND, GNDSWDIO, PA13NRST, PB4 (NJTRST)SWO, Not useMaybe E1 (NRST)...
After the Write-Enable command has been executed, the "HAL_OSPI_AutoPolling()" function will be called but, at the line of :status = OSPI_WaitFlagStateUntilTimeout(hospi, HAL_OSPI_FLAG_SM, SET, tickstart, Timeout);time out event will be accrued and s...
I have written 0x96 in an external flash at 0th address for 256 lengths and while reading it back the first byte had 0x16 and the rest of the bytes had 0x96 and this issue is observed occasionally.Settings:MCU: STM32L433SPI: SPI 1 in DMABit rate: 24M...
Hi guys,I have a short question regarding the STM32L552ZET6 power domaines. Can I use 1v8 to power the chip and connect a 3v3 power supply on the VDDIO2 which I will power on from time to time(when I need to use those pins)? And another thing if I do...
