The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on February 04, 2013 at 10:17 Hi , I am trying to drive a LED Driver IC with a PWM signal on button press. However , it seems that at the end of a PWM cycle the LED final state is not determinable (maybe on/off). It seem that it...
Posted on February 05, 2013 at 01:35What is the purpose of JP1? It connects to the STLINK MCU, and via two solder-jumpers on the bottom of the board (SB14,15) to PA9,10 of the 'F051 (the USART-1 pins). Can the STLINK enumerate as a CDC endpoint, a...
Posted on February 01, 2013 at 00:39I created some simple code on the STM32F05-Discovery board to write a byte of data repeatedly out USART1. However when I run this code on my target board the USART doesn't send the data. The TXE line goes low an...
Posted on February 04, 2013 at 17:30 Hi all, I trying to use the SPI and I am using uVision Keil. The clock appear with a latency that I can take off by removing while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET); But wh...
Posted on February 04, 2013 at 18:08 I want to read valuefromaccelerometer . Model 1 void GPIO_ADC1_setup() { GPIO_InitTypeDef GPIO_InitStructure; // Enable GPIOC clock RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE); // Configure PA1 as ...
Posted on February 04, 2013 at 16:50How long is the bus stalled for program Flash block erase and program operations? I would like to write to and erase Flash sectors while running an application from Flash in sectors not being modified. Reading ab...
Posted on February 04, 2013 at 16:29 Hi , as quoted from the audio implemination of stm32f4 eval : Mono audio streaming is not supported (in order to play mono audio streams, each data should be sent twice < br >on the I2S or should b...
Posted on February 01, 2013 at 12:10Hi, I have connected external flash memory to my board and using stm32f103vet6 controller. I want to drive this flash memory. So how can i drive that one? And after driving flash memory how can i make sure that fl...
Posted on February 04, 2013 at 15:44Hi, In my project, I have to measure the frequency of the input signal of an ADC. I use STM32F107 as micro and ADS1251U as ADC. is it possible? I will be grateful. Thnx for help #measure-frequency #adc-stm3...
Posted on February 02, 2013 at 20:59Hello! Just getting to know my brand new STM32F4 discovery board.Downloaded all the documentation, which is referred to throughout the site.Just thought I'd point out that athttp://www.st.com/internet/evalboard/pr...
