I need someone to write a 8051 program for me to use on a DS89C450 based microcontroller trainer board manucactured by Digilent Inc.([url removed, login to view],396,607&Prod=MDE8051)
I will use 8 DS18B20 temperature sensors for monitoring up to 8 different temperatures and a nokia 3310 lcd in SPI mode to display the temperatures.
to select the individual sensors,i will make use of the 8 switches built in the board and use the leds to to indicate which sensor is in use.
1 You will be free to select the i/o pins to be used.
2 1-wire device switching will be done in software and the sensors will be on the same 1-wire bus.
the lcd display will need to show which channel (0-7) is being displayed and display the temperature in an 12Bit resolution.
contact me for any questions.
