10+
11+ These examples are designed to demonstrate the use of libopencm3
12+ with the STM32F4Discovery-DISCO board. This board has a 2.2"
13+ TFT LCD touchscreen on it, a MEMS gyroscope, and 8MB of SDRAM.
14+
15+ If you move through the examples in this order, the code from
16+ the previous example will be used in the next example:
17+
18+ 0 . miniblink - verify that you can build a program, link it, and download it to
19+ the board. Blinks the GREEN LED at about 2Hz
20+
21+ 1 . tick\_ blink - Clock setup, Systick setup, LED GPIO setup and blinking.
22+
23+ 2 . usart\_ console - Program a USART on the board as a console (requires
24+ clonsing jumpers on your discovery board connecting USART1 to the
25+ programmer)
26+
27+ 3 . usart\_ irq\_ console - Program a USART on the board as a console with an
28+ interrupt driven receive routine. This allows you to interrupt execution
29+ with ^C as you can on a Linux process.
30+
31+ 4 . sdram - SDRAM setup, using the usb port as a console, which sets up the
32+ SDRAM
33+
34+ 5 . spi - Serial Peripheral Interface example which talks to the MEMS gyroscope
35+ on the DISCO board.
36+
37+ 6 . lcd-serial - Activates the TFT using the SPI port (serial) and holds a frame
38+ buffer in the SDRAM area.
39+
40+ 7 . lcd - Now uses the new LCD "driver" peripheral to refresh the contents with
41+ what is in memory, very fast, write in memory and it appears on screen.
42+
43+ 8 . dma2d - The 2D graphics accelerator device which displays various animations
44+ on the LCD using code from all of the previous examples.
