Hello, I was experiencing this weird thing lately with my STM32 Blue Pill board's COM Port.I'm using STM32duino (Blue Pill) with Arduino IDE. I've Already flashed the bootloader and installed the drivers for it. when i connect the board with my PC us...
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...
On NUCLEO-H563ZI board I put 3KHz square wave on LPTIM2_ETR (PC4). I want LPTIM2 to continuously count. However the count never increases. LPTIM2 setup...AndClock looks likeMX_LPTIM2_Init() looks likestatic void MX_LPTIM2_Init(void) { /* USER CODE ...
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...
