Posted on July 18, 2012 at 16:55I like the STM32F4 Discovery for deveopment before hardware arrives. It brings out many of the processor pins, and most of those pins are not ''hard wired'' to a function on the board. This accomadates developing f...
Posted on July 19, 2012 at 17:50 Hi, Another small littleconundrumI am hoping someone out there might help me solve. I have got an i2c master and slave talking to each other, I'm fairly sure the Master code is good as it's been wor...
Posted on July 02, 2012 at 10:03Hello everyone! I want to create a new topic for incremental learning with usb for beginners. I've started to learn usb library, seen examples, but I have many questions. First of all, I can't undestand, how to conf...

Posted on July 18, 2012 at 19:47Hello,I'm wondering how to create a parallel interface on the STM32F4Discovery Board, if possible. As far as the application, I would like to connect the Discovery to an external ADC evaluation module from TI (ADS855x...
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...
