Posted on November 12, 2012 at 11:23HI, Is where any makefile or ready project to build STM322xG_EVAL FW with yagarto or GNUARM? I have downloaded STM32F2-F4_Demonstration_Builder_V1.0.1 but it has no plain Makefile for GCC. I wonder if someone can...
Posted on November 29, 2012 at 18:44I've been experimenting with the CPAL I2C library and as a test I'm sending a short string of bytes to an external device. I'm the only one on the I2C bus and I'm configured as an I2C master. Does anybody know why...
Posted on November 29, 2012 at 09:45I am trying to use DMA1 Stream 1 Channel 4 in the STM32F205ZE (IAR Embedded Workbench IDE). Attempts to configure the DMA (using the Std Peripherals library) result in no change in the register values (all val...

Posted on November 28, 2012 at 22:36I'm trying to upload a ChibiOS demo to the STM32F3 Discovery board. The project builds fine under IAR and appears to connect & program correctly over the onboard ST-LINK. However, when I change the code (i.e. comm...
Posted on November 28, 2012 at 14:34hello everyone, i`m working on an academic project.i`m trying to read sensor values and needs to send the readings after calculation to PC via USB or Serial port Does initializing and sending data to USART1 requir...
Posted on November 29, 2012 at 09:38Hello everybody,I have a problem. I'm using STM32f103rbt6. I'm using SysTick and USART interrupts. They are working independently. SysTick is used for Delay operation. But in a case, I must use this Delay function...
