Below i have attached a code which enables the PLL freq of 72MHz using HSI of 16MHz. The issue is if I give a Timer pre-scaler of 36000-1 (I am using timer2, which in case of STM32F401RE is on APB1 bus so using a pre-scaler of 2 for APB1 which makes ...
Using Nucleo-U575ZI-Q (rev X) board I try to do a PoC - a very simple UCPD source app providing default USB 5V and 0.5A max. With undocumented onboard SB8-10 shorten this probably can be accomplished. I know this board does not provide output current...
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 ...
