Posted on April 29, 2014 at 17:16[STM32F107RC]I use MCO pin for generating RMII clock.I want to activate USART1 too.(I only need RX,TX,RTS and CTS pins of USART1)USART1_CK is duplicated with MCO pin and I dont need USART1_CK.(remap is not possible)I...
Posted on January 21, 2014 at 05:59I debug my C programs in Eclipse + GDB + OpenOCD by ST-Link/V2 (SWD), it works good.In my programs printf retargeted to ITM_SendChar (Instrumentation Trace Macrocell), and I can see debug strings (printf) in Serial...
Posted on April 20, 2012 at 07:39 This Project might be interesting, is the CDC Usb Virtual Port Example - that I modified to return ADC Reading values, and provide a simple Commands Shell Example, - which allow Reading and Writing of individual...
Posted on April 29, 2014 at 02:48Hi all,I have read section 2.1.10 in the errata over and over without really getting the message.http://www.st.com/web/en/resource/technical/document/errata_sheet/DM00037591.pdfDo the fine people at ST mean that DMA2...

Posted on April 27, 2014 at 03:25The picture is the wave form of STM32F429 osc_out pin,The low level is not 0V, but is 1.24V, Why the sine wave's value of peak to peak is 1.04V. Is it correct?
Posted on April 25, 2014 at 11:00All, 1.) I took 128, 16-bit data points and created a sine wave: const uint16_t Sine12bit[128] = { 2047, 2447, 2831, 3185, 3498, 3750, 3939, 4056, 4095, 4056, 3939, 3750, 3495, 3185, 2831, 2447, 2047, 1647...
Posted on January 14, 2014 at 10:52i use lcd with fsmc and i can display any color else white color lcd_clear(0xFFFF); // 0xFFFF this is while color and this not display any thing ? 0xFFFE this is (0xFFFF - 1) this give me white color but why 0xFFF...
Posted on April 24, 2014 at 15:08Hello, I noticed a problem in the software implementation of STM32F1 's clock/calendar. If the device is switched off for a long time (>= 255 days) it will enter infinite loop inside CheckForDaysElapsed() (which is ...
Posted on April 28, 2014 at 00:04Hi everyone, I'm trying to understand how registers and memory really works in a microcontroller and how to access data in registers using C Now I can access any address in the memory and I can write any data to it...
