Posted on April 22, 2013 at 15:07STM32F103 has one CAN only. I want to send and receive data using the same CAN in normal mode(For testing purpose, CAN sends and receives message itself ). I have tried loopback mode and it worked fine. But when I co...
Posted on April 25, 2013 at 11:41HiI can't find the STM32 embedded graphic library. I am supposed to find it here: http://www.st.com/stonline/stappl/resourceSelector/app?page=resourceSelectorPage&doctype=FIRMWARE&ClassID=1734 but I always get this m...
Posted on April 24, 2013 at 15:59 Hi, all. I working at ADC sampler implementation. ADCsamplerhas a next flow: Timer 1 generate sample rate at 200kHz.At every Timer 1 CC2 interrupt ADC1,ADC2,ADC3 take a sample.DMA is used to transfer s...
Posted on April 24, 2013 at 23:09Hi,i'm studying about GPIOs on STM32F4 Discovery but in the User Manual i don't understand very well how GPIOs work.Can someone helps me to understand how it works?GPIOs should be 9 ports of 16 bits that SoC uses to ...

Posted on April 24, 2013 at 13:33Hello everybody, I ever look on webside if previous post treat my problem, but they not resolve my pb. The problem is, I try to pramreter the TIM1 PWM output on STM32, but it do not work. The TIM1 counter register CN...
Posted on April 19, 2013 at 16:09Hi,I need to replace a 5V-uC by a 3.3V type and maybe it will be a STM32F0xxx. Now there is one question concerning 5V tolerance: If the 3.3V-uC drives an output that has a pullup resistor to 5V, is that any problem ...
