Posted on May 20, 2013 at 19:28 I am using TIM3 as an event timer to trigger external ADC conversions. I am having an issue where the timer interrupt fires too early and causes an out of range conversion result from the ADC. I notice that when t...
Posted on May 25, 2013 at 00:54Hi.Please help. I write simple app using restricted KEIL to operate with AD5292 via SPI for my academic research project. To achive this I wrote the following code:int main(void){ /*!< At this stage the microcontroller...
Posted on May 24, 2013 at 11:53Hello,I have configure Timer 4 in Compare mode with interrupt enable on STM32f103RB.I set the compare register to 500ms (72MHz System Clock).I have notice that TIM4 CCP1 Interrupt fire in 0.23ms (as measure with logic ...
Posted on May 20, 2013 at 12:22Hello,I'm currently designing my own schematic based on the STM32F4DISCOVERY board with a STM32F407.The quartz implanted on this demo board is a 8MHz. But there is a possibility to put a 25Mhz quartz. What is the diffe...
Posted on May 24, 2013 at 17:08Background: I have a lot of experience with Atmel processors (Arduino) and some experience with M68332 processors. Both have widely available examples and forums that help new user get started. With a running example...
