Posted on May 26, 2013 at 00:35Hi, is it possible to sample GPIOA Bit7-0 into SRAM as byte and to have kind of ''Clk'' nonPWM output on other GPIO , with higher speed than 20MHz on STM32F103 72MHz ? this gives me 10MHz clk output on PC2: Buffer_pt...
Posted on May 25, 2013 at 00:12 Hello! I'm new to micro controller programming. I have been told to ''poll a pin'' and perform a specific action if this pin ''goes low''. So I wrote this code to ''poll'' a PD10 pin on my board: GPI...
Posted on May 20, 2013 at 12:17Hi guys, i use am stm32f0 microcontroller.I've a problem about the ADC channel 13 (PC3 pin) and PA3 pin.when i connect something to PA3 pin seems that the ADC PC3 pin reads the PA3 pin value.this is my ADC configuratio...
Posted on May 25, 2013 at 12:42hi 1.)i have a little confusion, if controller can differentiate between system reset and power on reset itself?mean i want to skip few lines of code on system reset but not on power on reset2.) i have a stm32f4 discov...
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...
Posted on May 09, 2013 at 22:05 I'm using the RTC on an STM32L151CB and at some point I'd like to disable both alarms and update alarm A. I'm using the following code which doesn't work: RTC_AlarmCmd(RTC_Alarm_A | RTC_Alarm_B, DISABLE); R...
