STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on December 02, 2014 at 18:10 OK, I'm interfacing with a parallel bus that gives me 8 bits on an external clock pulse. I have working code with an interrupt and manually shuffling the data into memory, but I'd like to use a DMA approach, ...
Posted on January 12, 2015 at 16:00Hello, I'm trying to do a very basic thing, emulate a USB flash drive through an Olimex P407 board. Real data is stored on a micro sd card. I used STM32CubeMX for the first time to generate the code (I used it for ...
Posted on January 14, 2015 at 15:09I have used the STM32_USB_HOST_Library V2.1.0 (19-March-2012) on STM32F105 for implement Mass Storage Host class.The file system is has been implemented with FatFs Module Source Files R0.07e. The my problem is tha...
Posted on November 26, 2014 at 19:05 I have transferred code for ADC using an interrupt from STM32F405 to STM32F302 but it seems that the interrupt is probably fired again immediatelly after return. I see it by a permanent lit of a LED and on sc...
Posted on January 16, 2015 at 06:08Hello! I need to have 16-bit audio, 4 channels (at least) input with STM32. Has anybody developed something like this? I found many ADCs on the net, but how to get ADC data without spending too much time on interru...
Posted on January 14, 2015 at 19:12Hi guys,I'm currently trying to interface http://www.wvshare.com/product/4.3inch-480x272-Touch-LCD-B.htm with the STM32F429I-Discovery board, but I don't know where to start. After lines connection (for the moment ...
Posted on January 14, 2015 at 20:51 Hi, I have the MCU run SysClk at 168MHz, and I setup the timer to capture mode, but the returned value is two times bigger than expected. I checked the waveform of the toggled LED, it is correct, just the Time...
Posted on January 15, 2015 at 22:22Hi,I have a question regarding open drain configuration for SPI communication in the STM32F030x Family of MCUs. I have successfully configured the SPI interface with open drain outputs and external pull ups (for co...
Posted on August 21, 2014 at 20:20Hi, I've been trying to use the new F4 HAL libraries for a project on the F429 Discovery board. I realise that this will involve a lot of C to C++ integration.My first issue is with the two enum typedefs in @f...
Posted on January 15, 2015 at 18:45Should this work? I have the I-Jet plugged into CN16 and am using it with IAR EWARM and running ''emuDiag 3.57.'' The STM324x9I-EVAL is powered via USB and I have modified project options to use this debugger.The t...
