Project Description

---------------------------------------------------------------------------
This project provides a quick start on using ZiLOG’s ZNEO series of microcontrollers that presents a set of ready to use APIs for ZNEO’s on-chip peripheral such as such as System Clock, Timer, Multi Channel Timer, ADC, UART, ESPI (Enhanced serial Interface) and GPIO. The project also provides APIs to communicate with 4-bit I2C EEPROM (PCA8550), SPI Digital Thermometer (DS1722), and controlling the dot matrix LED displays through GPIO. The APIs provided in this project are listed below.

· To configure the ADC to measure the analog input voltage on the channel selected

· To read the ADC output value upon analog to digital conversion complete

· To configure the I2C in Master mode along with transmit, receive, checking the acknowledge, Start and Stop functionalities

· To configure ESPI peripheral to function as SPI in master mode along with transmit and receive APIs

· To configure TIMER0 in continuous mode of operation

· To configure Multi Channel Timer for PWM mode of operation

· To configure GPIO for controlling the dot matrix LEDs

· APIs for writing and reading from on board I2C EEPROM

· APIs for writing and reading from on board SPI digital thermometer

Application demonstration
---------------------------------------------------------------------------
The sample code demo is designed for use with ZNEOCTK0100KIT ZNEO Contest Kit.

Setup

NOTE: Refer to ZNEO Contest Kit Board manual (UM0197) for complete hardware details.

Connect the console port on the kit to COM port on your PC
Launch the Hyper Terminal with following settings
Baud rate 57600bps (as set in uart.h file), 8 data bits, NO parity, 1 stop bit and No flow control
Build the project in ZDSII and download the code to the device using the debug tool

(Example: USB/Serial smart cable)

On device reset, following menu is displayed on the HyperTerminal.
