Posted on August 22, 2012 at 14:09The following code (TIM3 has clock enabled in RCC but otherwise is in its reset state):#define TEST_TG #ifdef TEST_TG TIM3->DIER |= TIM_DIER_TIE; // enable interrupt from trigger TRGI #else TIM3->DIER |= TIM_D...
Posted on August 21, 2012 at 11:33Hi. As i m currently working on an application running on both STM8S and STM32, i'm using firmware libraries to get a portable code. i already found several mistakes. As an example : Software NSS bit. - first mistak...
Posted on August 21, 2012 at 19:45Hi all, I use STM32F205xx for my project but I did the same results with STM32VL Discovery kit. I debug in Atollic TrueSTUDIO 2.3.0 Lite and I tried TrueSTUDIO 3.1. too. The problem is that code char a = -50; s...
Posted on August 21, 2012 at 19:34Hi, I have a problem with Timer16 of STM32F0 Discovery. I want use this timer like ''time base'' one interrupt at 1mS. It Works but this timer has a ColockDivision ? Because when I setting the ColockDivision at :1 ...
Posted on August 21, 2012 at 17:18Hi, I was wondering if someone can help me, I have managed to invoke the STM32f407 using my application firmware, I then run the Flash Loader Demonstrator and everything seems to be working fine however if I try and...
Posted on August 21, 2012 at 17:29Hello everyone, I am new to embedded programming. I was using Stm32l discovery board. I was trying to use the timer input capture mode to measure and then display the frequency. After initialization, it shows 00 fr...
Posted on August 18, 2012 at 01:26Hello everyone.., I am new to Embedded programming. I wanted to generate 2mins delay. I already want to use two timers in PWM input and Input capture mode simultaneously. Can I use RTC to generate 2mins delay? Than...
Posted on August 21, 2012 at 12:11Hello All,I have configured an user button(connected to PG15) on the evaluation board(MCBSTM32F200) to generate an interuppt when pressed. The GPIO is iniztialized and works fine however the IRQ handler is never ent...
Posted on January 23, 2012 at 16:04Hi, I want to play wav files from an SDCard with my STM32F2xx. I used SDIO example and I added FatFs support on it and it's OK. Next, I tried to use STM audio example to play audio from memory, and it's work (first...
