Chapter Iii Software Development And Examples - Embest EB-SAM3U User Manual

NandFlash Read and write to external NANDFLASH according SMC.
SRAM Test the external SRAM. Read and write it. If success,D2 lights,else D3 lights.
TIM This procedure mainly tests TC module of the board. Configure TC working in
Waveform Mode. RA=0x1000. It will generate interrupt and turn on LED light
when generating Comparing matchs.
HSMCI This procedure tests the HSMCI interface by using a SD card with FAT32 file
system. It can format the SD card, write in a bin file, read it and compare its
contents with the contents writen in previously.
SSC This sample can play the WAV file, related Information can display in
HyperTerminal.The WAV file must be 48KHz samplerate，Two-channel stereo,
and Previously stored in the SD card. SSC interface connected to WM8731,can
send audio data to WM8731,which decode simply and play. You can hear the
music by using a headphone.
SPI Achieve the communication between SPI interface and touch-screen controller.
Touch-screen controller can receive the commands sent from SPI interface and
Feedback the corresponding data to SPI.
Touchscreen The main function of this routine is to obtain the coordinates of the touch-point
on the touch screen, and print it in the serial port and LCD screen.
LCD LCD display routines. It can display characters, text, graphics and so on.
TWI This procedure test Temp.Sensor according TWI. It can read the values of the
sensor internal registers, access to the current configuration, and get the current
temperature value.
UDPHS This is a USB mass-storage test case.There are two DISK sample in this project,
one for Extended SRAM addressed from 0x60000000(size: 512KB),one for SD
Card inserting on the SD/MMC socket of the board.
USB_CDC This procedure achieves the USB Communication Device class(CDC) serial
communication test.
RTX_Traffic BLINKY test case based on RTX operating system. It simulates the changes of
traffic lights at a crossroads.
Chapter Ⅲ Software development and
examples
Example operation sequence（take ADC character display for example）
1. Open ADC folder, Enter ADC folder, double-click adc.Uv2 project file， then will open this
project file.
2. Project file include StartUp Code （storage area of startup codes） , Source Code （storage
area of main source program codes）, System Code（program library source files）and
Documentation（program document description）folders.
3. Connect the power line and emulator wire to the board (between ULINK2 and JTAG）.
