Posted on July 18, 2012 at 04:37 Hi there, I tried to use my STM32f4 Discovery (164MHz) to read data from OV7676 camera (No FIFO) without using DCMI module. I just used normal gpio pins to read 8-bit data from the camera along with VSYNC, HR...
Posted on July 18, 2012 at 13:41I am having some problems in that the SCLK signal for my SPI (when using either SP1 or SPI2) appears to be incorrect. Although the period is stable throughout and as I would expect, the clock pulse itself is non symme...
Posted on July 18, 2012 at 12:37 Hello, I am using the STM32L-Discovery board and try to transmit / receive data via USART1. My problem is that the controller does nor react on data sent from the PC, but if I send one byte from the contr...
Posted on July 16, 2012 at 07:23Hi all! I have two questions on how to interpret the documentation for the USB FS device macrocell in medium density devices. 1. The section on OUT transactions states that when a buffer is overrun (i.e. the data payl...
Posted on July 10, 2012 at 22:00Hello! I would like to send simple data from STM32F4Discovery to PC (''Hello World!'' every second would be perfect for beginning). I am pretty lost here. How do I create virtual COM port? When I connect PC to the bo...
Posted on July 16, 2012 at 18:14Hi,Just a very quick question - is it fairly easy or even possible to bridge or tie 2 I2C ports together using a DMA. It's just something that I'm looking to do due to a change in a requirement whereby we just want to...

Posted on July 14, 2012 at 17:09Hi all, I am developping an application on 16K RAM device and I am facing limitation of RAM size so I want to optimize the definition of the following pointer to strings and I want to know if I am well understanding ...
Posted on July 16, 2012 at 23:46I use the ICSR register inside an interrupt service routine to determine which vector was used. I use the low 9 bits to identify the currently active interrupt. I'm not clear on what happens to the ICSR if nested int...
Posted on July 11, 2012 at 15:12Good Day I am new to ARM and Atollic TrueStudio. I decided to get going by downloading and testing an existing demo project which has functionality I require and the understand it and move forward. I have a STM3220G-E...
