Posted on October 17, 2012 at 11:48Hi everyone!I'm new to the world of microcontrollers, these days I'm doing my first espeienze with STM324 discovery, I'm reading the various manuals and trying out the various examples, but I can not understand how...
Posted on October 18, 2012 at 08:59Hi everybody. I used SysTick timer as a counter of time in my application throug using of interruption. I found ''SysTick_Config'' function in core_cm0.h file. This function load time to reload register and switch ...
Posted on October 18, 2012 at 11:41I submit a problem with crc calculation in a spi communication with dma facilities:I receive on STm32F103 some spi frame (14 bytes with CRC included) with the attached code.At reception of the frame, the crc calcul...
Posted on October 17, 2012 at 11:38Due to an error in manufacturing we have a lot of modules with a 32khz resonator with 12.5 pF for low speed external clock and two 27pF aditional capacitor to ground. Prozessor is the STM32F103RCT6. The real time ...
Posted on October 17, 2012 at 01:49Hi All,I’m using an STM32F103x. I need to count the number of external pulses from a hardware detector, and take a snap shot of the pulse count at a precise frequency of 100,000 kHz.My current setup uses TIM5 CH...
Posted on October 16, 2012 at 22:58 hello, i am trying to learn how to use DMA for frame buffer. Idea is to manualy fill SRAM with data (10k points each 16b) and send to LCD by using DMA. FSMC_Bank1_NORSRAM2 and adress: #define B...
Posted on October 08, 2012 at 19:36Which to believe-- STM32F32x datasheet (Sept, Doc ID 022691): Page 40, Table 15, Alternate functions for port PB, shows COMP1_OUT and COMP2_OUT for AF8 on PB8 and PB9. Table 14, port PA, shows PA0/PA6/PA11 and PA2...
Posted on October 17, 2012 at 17:36Hello, I am new to ST microcontrollers, just maybe 2 weeks ago I accidentally found about this crazy chip (STM32F4) and now i am already playing with it. I am interested in the I2S hardware and audio processing, so...
