Solution for NesC ADC Reading Program in TinyOS

Issues  &  Solution

Configuraton for the TinyOS-2.1.1[Solution for the Reading data from ADC ]

Same configuration we can apply to lower Versions of TinyOS If Following error occurs while doing the Programs

1. SensirionSht11C.nc Component not found.

/opt/tinyos-2.1.1/tos/sensorboards/mda300/SensirionSht11C.nc:53: component SensirionSht11ReaderP not found

In file included from /opt/tinyos-2.1.1/tos/sensorboards/mda300/SensirionSht11C.nc:60,

from /opt/tinyos-2.1.1/tos/sensorboards/mda300/SensorMDA300CA.nc:94,

Status :Issues Solved

By Adding the Sensiron Component from /chips/sh11/ in to the /sensorboard/mda300/ Sensor Directory

2. Cannot Find Int3_interrupt

In component `HplSensirionSht11C':

/opt/tinyos-2.1.1/tos/sensorboards/mda300/HplSensirionSht11C.nc:69: cannot find `Int3_Interrupt'

In component `MDA3XXDigOutputC':

/opt/tinyos-2.1.1/tos/sensorboards/mda300/MDA3XXDigOutputC.nc:63: cannot find `Int0_Interrupt'

Satus:Issues Solved

Edit the DIOP.nc file by comment the the signal readDone event [ It will disable the implicit the signal raise for I2C by enabling the digital pin connected to Atmega 128 Microcontroller to MDA 300 CA Data Aqusition Board]

By adding the 1 KOhm Resistance to the VCC - CLK and VCC to Data will enable the I2C on the Board
