Posted on December 29, 2013 at 21:25I'm currently using a ST-LINK/V2 to develop code for STM32F205/7, but am wondering if I would be better off with a Segger J-LINK. What's the difference in capabilities between these two? I using the Atollic IDE/co...
Posted on December 28, 2013 at 14:27I would like to know if there exists a sample code on which I can elaborate to do the following:Transfer data stored in a variable on the microcontroller to computer software such as MATLAB through the USB OTG int...
Posted on December 28, 2013 at 15:22what is the difference betwee TIM2_CH1_ETR and TIM2_ETR? I'v only found TIM2 has the TIM2_CH1_ETR, all other TIMs, such as TIM1, TIM3, TIM8, only have TIMx_ETR. I'v also found the problem that only TIM2 can be tri...
Posted on September 12, 2013 at 17:12Guys, Does anyone of you have experience on interfacing VS1003 with STM32? Any ideas or links will be appreciated, Thanks #interface-anything-to-anything
Posted on December 17, 2013 at 00:05We're using a UART to pass control information between two STM32 parts. The bit rate is 500Kbaud which gives us about 20us per byte. The aim is to use DMA to receive the byte stream in the background and process...
Posted on December 27, 2013 at 03:00Hi, I'm posting for the first time here. Does STM32L100RC have opamps? I'm asking this because I am finding conflicting information: When I go to: http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1295 and click...
Posted on December 17, 2013 at 10:26Hi My product is based on stm32f407, the Ethernet works well normally, except that, sometimes(10% possibility) after the MCU powered up or hot rebooted, the mac can transmit packets, but can NOT receive. When thi...
Posted on September 12, 2013 at 04:07 Hello, I have paired up an STM32F4Discovery board with an FT2232H part from FTDI. The purpose of this is to use the CPU-FIFO mode of the FTDI part for faster USB data transfer. I made the necessary mo...
Posted on December 27, 2013 at 13:07Hi I have downloaded the STM32_USB-Host-Device _lib_V2.0 library for USB Mass storage Application.I have taken the mass storage example and compiled for my board(STM32f217). But when I connect my pendrive to the ...
Posted on January 04, 2012 at 14:56PROBLEM: Timer interrupt is entered immediately in the beginning and not in the desired timing period. The objective is to enter a service routing of TIM4 with a timing of every 10 sec, clock is 72Mhz: TIM_TimeBa...
