Posted on December 31, 2012 at 16:49I will use the STM32 to drive a power supply. The input signals to the ADC do not need any gain, so I'd like to avoid using as many OPAmps as possible. The problem is that many of the potentials are negative or ...
Posted on December 29, 2012 at 01:28I've got a mixed-signal board with an LCD connected through noisy SPI lines. When the display is being updated, the analog readings are all over the place. In addition to improving the layout of the board, I'm als...
Posted on December 30, 2012 at 21:28I have been working on a program to directly transmit any character or set of characters that I transmit from the PC via UART, back to the PC immediately. This is just the first step in my project. Code (this work...
Posted on October 11, 2012 at 17:02Hi everyone I did an application board which is containing stm32f405rgt6 but I'm not programming it with stm32f4discovery. I removed the 2 jumpers on cn3 and I did what manifacturer say in ST User Manual UM1457 at ...
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...
