Hi,I am working with STM32G491RE in my project. I have to transmit data through UART and I need to calculate CRC for that data.in my application:txdata[0] = 0x78;txdata[1] = 0x04;txdata[2] = 0x11;txdata[3] = 0x01; I have to calculate CRC16 for txdata...
Hi,I've created a PCB with an STM32L4x6 microcontroller and several peripherals, mainly I2C. I want to sample data at 512Hz using the internal ADC. The original plan was to configure the ADC with DMA and a timer, I'd put the MCU into other low-power...
I'm working on a bootloader with an STM32F072 device. At the end of the programming process, I followed the steps in the link below to switch to the user application:https://community.st.com/s/question/0D53W00000trgpiSAA/how-to-boot-to-random-address...
While I could not find a maximum RTC input clock limit in the datasheet, I believe the underlined phrases should say "max.1MHz". As it is phrased now, it appears to call for exactly 1MHz which I doubt is mandatory.JW
This is not true, according to RM, HSE is divided by RCC_CFGR.RTCPRE which ranges from HSE/2 to HSE/31.JW
Hello,I'm using an STM32F205 chip with custom bootloader. I am facing an issue, that when main application is loaded through the bootloader some of the uart's (USART6 and UART4) interrupt transmit (HAL_UART_Transmit_IT()) causes the stm32 to crash. O...
I am going to have an external high speed signal as input to the MCU. I want to use a 32-bit timer to count the number of cycles on that input. Will a regular timer keep counting even in CSLEEP or CSTOP modes? Or do I need to use an LPTIMER. The LPTI...

Hello,In appnote AN3156 (Rev 14) [USB DFU protocol used in the STM32 bootloader] it saysThe bootloader version is returned in the device descriptor in the MSB of the bcd devicefield (example: 0x2000 = version 2.0).In appnote AN2606 (Rev 59) [STM32 mi...
Hello, I have a question for you, does the ST company have a program for the Rust language?
