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). ...
Posted on November 07, 2015 at 18:12 hello, I'm trying to create delay of 1 second and toggle an LED. I'm using SysTick timer for this task. I have STM32F103C8T6 mcu. The following code does not work. Looks like the control never reaches the...
Posted on November 05, 2015 at 10:21helloas required in the STemwin manual i have to enable RCC AHB1 CRC clock. ''The CRC module (in RCC peripheral clock enable register) should be enabled before using the library''trying to use RCC_AHB1PeriphClockC...
Posted on November 04, 2015 at 10:46Hello there I've a question regarding the ADC conversion time on the STM32L476. According to the datasheet the fastest possible conversion time running at 80MHz is 187ns. Does this also count for the continuous co...
Posted on March 02, 2013 at 22:52Hello,In my project i need to measure the frequency of 8 external signals with the STM32F4 Discovery Board. So i begin with the first signal by using Timer 1 in Input Capture mode and it works. Now i'm trying to do t...
Posted on November 07, 2015 at 15:03I'm learning to use the ADC in an F2 device. I was looking for the ''proper'' way to calculate values rather than making any assumptions like every single tutorial or example code that I've seen so far. One useful...
