Posted on January 25, 2013 at 06:39Dear All, I bought any product that contained STM32F103C8T6 48-pin mcu. I try to re-program it with my own hex file using Flash Loader Demonstrator and it can be wrote and verified correctly but the application can...
Posted on January 24, 2013 at 17:42Hello, I have an issue while 2 STM32F103REY are connected through i2c, 7bits addressing. It works good in the following cases: master transmitter master receiver for 1 byte master receiver for n bytes, n >=2 Not ok...
Posted on January 24, 2013 at 21:54Hello, My problem is that I don't get the Frequency produced by Timer 16 seen on PB8. Somebody can have a look at the code and tell me what's missing or wrong. static void setup_Timer16(void) { TIM_OCInitType...
Posted on January 24, 2013 at 16:18Hello, I'am struggeling with a timer delay function, I've made a delay_us() function with help of timer14 However, when I have a delay which is close to zero I have lots of deviation. Here is my initialisation:#de...
Posted on January 25, 2013 at 01:05I have designed a custom board around STM32F407VET. I am using 8 MHz external oscillator (ABRACON ABLS-8.000MHZ-B2-T) with 22 pf load capacitors (CL) and 220 ohm REXT. When I probe OSC_IN or OSC_OUT pins using lo...
Posted on January 24, 2013 at 17:03Hello,I need to design a system which will compress a data with rate of 1000:1 minimum in the range of determined time.I want to compress data (tera bytes to gigabytes) and to save to SD card.I searched about open...
Posted on January 22, 2013 at 16:53 I am having some trouble setting up an external pulse duration measurement on a Timer. Ideally I'd like to capture the duration of just the first incidence of a pulse on the desired pin, but that could require ...
Posted on January 21, 2013 at 10:50having difficulty getting a custom bootloader working. Basically this is a MSD device bootloader, using USB MSD and SDIO Sdcard drivers and Chan FATFS. Note MSD only runs if there is not a valid binary file on disk...
Posted on September 01, 2012 at 05:25I'm running some ADC tests on a VLDiscovery board. The values returned for sampling the internal temp sensor and voltage reference seem to move around in surprising ways. Here's some data:> ADC samples: channel 1...
Posted on January 24, 2013 at 08:03Hello,I have been working with STM32F4 Discovery for a while. I haven't had any trouble before but I found some problems that I want to know why it happens. Currently, I'm trying to use external interrupt at 125kHz...
