Hi,Im trying to get CRC16 - DNP from a string array that its the next:char Message2[] = { 0x00, 0x00, 0x00, 0x29, 0x30, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x31, 0x30, 0x30, 0x30, 0x30, 0x30, 0x30, 0x30, 0x32, 0x30, 0x36, 0x33, 0x57...
Hi there i m a student working on STM32F723 the first time, I encountered an register setting example as follows: GPIOC->MODER |= ((2<<(6*2)) \ (2<<(7*2))); i konw its setting the GPIO register but whats the meaning of * and 2<< at the beginning sen...
I'm a bit confused about the necessity of clocking the SWD ports using STM32G0B1 chip.There is a I/O port clock enable register (RCC_IOPENR) that enables the functioning of each of the GPIO ports (Port A - Port F), its reset state is all zeroes, so n...
I have an app where I timestamp all the data I get from a bunch of external devices. I'm trying to come up with the fastest way to read the RTC and have 2 approaches, one using snprintf and some LL driver code that's pretty easy to read. It's not m...
Hi,Reverse bootloader, code to perform firmware update can reside in the last sectors of the STM32 Flash?I am interested in using firmware update via USB Host DFU, but the application has a dual clock speed boot, to reduce consumption when not connec...
I try to using the bare-metal programming this is my code RCC->AHB2ENR |= (1UL<<0); // Enable clock to GPIO port ARCC->AHB2ENR |= (1UL<<13); // Enable clock to ADC1,2 GPIOA->MODER |= (1UL<<0); // Set PA0 to analog modeGPIOA->MODER |= (1UL<<1);// GP...
Hi ,I am using nucleo stm32f411RE board from more than 6 month but from yesterday suddenly I getting no st link detected . here I don't think i did any thing wrong with the board.observation :1. once I shutdown laptop and open again then both RED LED...
Hi Everyone,As soon as I learned and successfully transferred data from CM7 to CM4, I bricked my H747-Disco. So, I brought the Disco home from my microscope Lab to place a solder bridge on R192. I realized reading glasses today just doesn't work for ...
I'm working on a project with an STM32F103VCT6 where I'd like to use the ADCs in combined regular/injected simultaneous mode. At a high level, I want to measure the system voltage and current simultaneously every 1ms, and then I want to periodically ...
Hi there.I'm trying to read a button status using STM32F103C6 (fake BluePill) with STM32CubeIDE 1.13.1 and/or using Labcenter Proteus to simulate. However, the reading does not work correctly. I would like some help to understand what is missing.My p...
