Posted on November 08, 2015 at 16:59Hello all, Data is coming from uart in chunks of 30 bytes via uart. I want to get these incoming chunks of 30 bytes and store them in a circular buffer of size 240 bytes by using DMA. I want to configure the DMA s...
Posted on July 09, 2014 at 18:51Hello,I have a working SDIO FATFS project on an STM32F4 Discovery PCB.This project works nicely at system clock frequencies down to 24 MHz.When I try running the project at system clocks of 16 MHz and 8MHz, the SDIO C...
Posted on November 07, 2015 at 11:42Hi. I'm fairly new to the concepts of ADC and currently, I'm using STM32F4 Discovery. For ADC, I have these settings for my ADC settings in my ADC_init() (source codes from an author online). ADC_CommonInitStruct....
Posted on November 06, 2015 at 08:35I have the following Problem: I have two input signals. The frequency of the signals is equal, but there is a delay between this signals. I have to measure the delay between the rising edge of the first input and ...
Posted on November 02, 2015 at 05:35 Hi all, I have just started learning ARM and have picked up the STM3F4 discovery board. Below is my first code to light up all the 4 user leds on board (connected to GPIOD 12to 15). ...
