Posted on August 29, 2012 at 02:18 I wanted to explore the SYSCLK on the STM32F0DISCOVERY board so I wrote a quick program to route SYSCLK to the MCO pin. I connected a logic analyzer to the pin and I see a ~200Hz clock with lots and lots of noi...
Posted on August 28, 2012 at 18:08 Hi, I have several questions concerning STM32 timer configured in PWM input. First, I need to capture 3 PWM signals.Each signal to measure needs two timer channels in order to capture Period and D...
Posted on August 28, 2012 at 12:14Hi, I'm beginner with stm32 (and other microcontroller), I read datasheet of stm32 discovery, but i don't understand how to do a simple counter. I understand how to initialize counter, but not how to use it. I searc...
Posted on August 28, 2012 at 11:27Hello, I'm suspecting my interrupts to trigger a lot more than necessary ... What is the less intrusive and quickest way to monitor interrupt triggers with only SWD (no SWO) ? Thomas.
Posted on August 27, 2012 at 22:25Hi, I used uint8_t CSD_Tab[16] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}; to initialize an array. But when I use IAR EWARM to watch the content in this array, the value is always unchanged. Any ideas? Thank you
Posted on August 11, 2012 at 09:46About 45 minutes into playing with my new VLDiscovery board, I seem to have bricked it. I downloaded a ''bad'' program onto the thing and now it's telling me that the device is protected and resists all my attempts ...
Posted on August 27, 2012 at 15:40Hi, I am working on read,write to a SD card using SPI method on board STM32152L-Discovery board. Now I can create a folder, create a file, and read, write. But when I want to get the capacity of the SD card, no matt...
Posted on August 03, 2012 at 04:44i am using the F0 DISCOVERY, after down load my build, when i want to down load again,the ST-LINK reports 'no target connected ', i reinstalld the driver, but it is not useful, what should i do
Posted on August 26, 2012 at 13:35The device has a fixed pullup on D+ (1.8k resistor to 3V). In software I am switching back and forth between a USB DFU bootloader and a non-USB application. My problem is that after returning to the bootloader, it i...
Posted on April 22, 2012 at 20:52Hi, working with the STM32F103 processor, I`m searching for a solution to sychronize a STM32 timer to an external input signal. This signal has a constant frequency of e.g. 24Hz or 30Hz. Using a input capture timer...
