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...
Posted on January 09, 2014 at 17:19I have setup the USART to Tx/Rx however my application requires sending a Break. The STM32F programmer's manual refernces sending Idle and Break, provides an example and register for sending an idle character but n...
