I want to run MCU with VDD 1.8V (in order to have all I/O-signals as 1.8V). I changed to use a LQFP64 package which provides a dedicated pin for VDDUSB.I power VDDUSB with 3.3V (for sure not below 2.7V) but all other VDDs on MCU are 1.8V:USB functio...
Hello, I am using STM32F042K6T7 microcontroller for doing some start-up configuration for some Ethernet PHYs by SMI, it is working well at room temperature, and cold (-40°C), but when I increase temperature max (+74°C) the microcontroller it seems is...
if I configure the USART and use HAL_UART_Transmit. The UART to USB bridge is taken care of by the ST-Link chip.Could i use the VCP on the board is on PA9/PA10(pin D14 and pin D15 to rx and tx to arduino) and use digital.read on arduino to get the in...
I have configured the M7 clock to 480 MHz and the M4 clock to 240 MHz using the HSI as input. In SystemClock_Config routine the statement__HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);is crashing the STLINK-V3 with the error messageEr...
I'm trying to update a transmitter called a wfly et16s. They have downloads on their site to upgrade their radio to expresslrs which is just a newer protocol. I installed the stm32 driver and it shows its working, I can connect to stm32cubeprogramme...
Hello,I'm using a STM32U5A5VJTXQ MCU and I need to use the 2K BKPSRAM located @0x40036400.I can read and write without problem the BKPSRAM after power up, but a power cycle corrupt all the content. Strangely, the RTC content: time and registers, are ...
Hi,I am at the beginning of my STM32F756VGH6 register programming journey. I have already setup everything, and now I am at the led blink (using a logic analyzer for measuring the time intervals). I decided to make a simple blocking delay function ou...
Hello,I've got a setup where I put the STM32 into STOP mode, with wake-up on ADDR match on I2C.SYSCLK is PLL 32 MHz.APB = 32MHz.I've configured I2C to use HSI, and enabled STOP_WUCK.(The I2C uses DMA).If I enable HSI16KERON then the device responds a...
I was wondering if an stm32h7 could run open source calculator Firmware epsilon, i would need to rewrite an interface layer, and don't want to work for days so i can find out that the stm32 is not strong enough.
