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 January 07, 2014 at 06:07hi there, I am running an issue about using DMA to transfer data bytes from ports to internal RAM at 12MHZ. I have succeeded in doing so, but I loose first few hundred of data bytes in doing so. Can this could be a...
Posted on January 10, 2014 at 10:46 Hi, I use STM32 vl-discovery in my project. I've connected and configured USART1 + DMA1 with informations and code from this forum. Application almost works, but all data in DMA memory receive buffer...
Posted on January 10, 2014 at 14:38In general, how do I go about getting a program I write which runs on the Discovery board to communicate with a PC over one of the USB links? Anyone got a pointer to reference material or examples?Dirk
Posted on January 10, 2014 at 03:32when i try to write data into a file use SD_WriteMultiBlocks function then some blocks didnt fill the data i want, the block looks filled with old deleted file data and all this blocks start with XXXXXe00 end with ...
Posted on January 09, 2014 at 09:56I have a board with an STM32F100 and a quadrature encoder connected to TIM1 channels 1 and 2 PA8 and PA9, the index output is connected to GPIO pin. I have checked the input from the encoder and it is generating th...
Posted on January 05, 2014 at 19:36Hello, the STM32F105 Device share USART1-TX and VBUS for USB on Port PA9. I need the USART1 for communication and for the internal Bootloader (only USART1 on my used 64pin Devices possible), if the firmware corrupt...
Posted on January 08, 2014 at 16:06HiI'm working on a project where I use a interrupt from the RTC. This is the one second interrupt. I also use a couple of other interrupts, for example timer 3. The RTC interrup can have the lowest interrupt possib...
Posted on January 10, 2014 at 06:05Hello all, hopefully someone can see the error of my ways? I have a some hardware with a couple of rf modules IO lines connected to Port D pins 10, 11, 12, 13. All is well except for pin 13 which is always providin...
Posted on January 09, 2014 at 20:19Is there some way I can programmatically turn off the LCD Backlight on the STM32F429i-Discovery when I don't need it?Tx
Posted on January 08, 2014 at 21:05I have a legacy system that uses a STM32F103RE device and I would like to connect to it via JTAG (or any other on board option) and view the code on the device to verify it's version (and possibly update). It seem...
