Posted on August 15, 2011 at 05:52Hi,I am doing a very simple test, enable EXT11 interrupt. In the ISR, I toggle a GPIO pin. I connect the scope to both EXT11 line and the GPIO I am toggling in the ISR.They somehow do not match. It seems ISR is skip...
Posted on August 12, 2011 at 15:05I have no clock on PC12. But when PC12 is OUT mode it is work. If I run mySDInit() I will see two jump on pc12 ( out mode test ). No clock. Where is the bug?void mySDInit( void ){ uint32_t regSDIO_CLKCR; GPIO_In...
Posted on August 15, 2011 at 13:50Hello I would like to switch from the HSE oscilator to the HSI oscilator if there is a failure of the HSE oscilator. How can I do that with preserved SYSCLK (64MHz)? The HSI klock is divided på 2 så the PLL would ...
Posted on August 09, 2011 at 08:41Hello, Since the beginning of the project on the STM32F205RG, I had hard faults from time to time. These last days, I wrote a hard fault handler as described in Joseph Yiu's book to see why ... and the result was ve...

Posted on August 13, 2011 at 02:59Hi all, I am a hardware guy and a beginner to STM3220G-EVAL. I jusy bought this eval board and was trying to use the IAR evaluation to educate myself. However, from ST web, I couldn't find the source codes which I l...
Posted on August 06, 2011 at 00:00I'm using the STM32F103RCT6. I need two PWM outputs, where the period and polarity of each is the same, but one output is 180� out of phase from the other. A duty cycle change must affect both concurrently. The c...
