A monitor system with multiple features using an Arduino Mega 2560

Short and quick readme until I have more time to go over this!

• Serial Communications (both for debugging and commands)
• Powermode features for low power usage/standby
• Read current and voltage every 100ms (readOnce, readAverage, readMin, readMax and reset stores)
• Read ambient light every 100ms (readOnce, readAverage, readMin, readMax and reset stores)
• Read sound signal every 100ms using fft (readFundamentalFrequency, readVolume, readAverageVolume, readMinVolume, readMaxVolume, readFrequencyWaveform and reset stores)
• Visual Basic program to interface with arduino

The arduino is designed to allow the automated testing of instrument cluster software.

Serial communication baud rate = 9600

Will add later, for now just look at the code and find online...

None

PM = 1

The voltage at the input pin is read every 100ms and the store values (Minimum, Maximum, Average) are updated.

The Average value is calculated by using the previous 5 scheduled read values, if less than 5 reading have been taken since power on or receipt of a "Store Reset" command then the average is calculated using only the available data. i.e. if only 3 records are available they are added together then devided by 3.

Reads the current voltage (on demand) from the input and returns the value at a resolution of 0.1v per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the current stored Average value is returned at a resolution of 0.1v per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the Minimum voltage that has been seen since the "Reset Stores" command was received (or since Power On:- PM = 1), the value at a resolution of 0.1v per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the maximum voltage that has been seen since the "Reset Stores" command was received (or since Power On:- PM = 1), the value at a resolution of 0.1v per bit in a 16bit number (xx = MSB,yy = LSB).

Resets the stored valus for minimum and maximum to zero (Voltage), returns 1 if reset was successful, 0 if not successful.

PM = 1

The current at the input pin is read every 100ms and the store values (Minimum, Maximum, Average) are updated.

The Average value is calculated by using the previous 5 scheduled read values, if less than 5 reading have been taken since power on or receipt of a "Store Reset" command then the average is calculated using only the available data. i.e. if only 3 records are available they are added together then devided by 3.

Reads the current (on demand) from the input and returns the value at a resolution of 0.1ma per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the current stored Average value is returned at a resolution of 0.1ma per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the Minimum current that has been seen since the "Reset Stores" command was received (or since Power On:- PM = 1), the value at a resolution of 0.1ma per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the maximum current that has been seen since the "Reset Stores" command was received (or since Power On:- PM = 1), the value at a resolution of 0.1ma per bit in a 16bit number (xx = MSB,yy = LSB).

Resets the stored valus for minimum and maximum to zero (Current), returns 1 if reset was successful, 0 if not successful.

PM = 1

The ambient Light at the input pin is read every 100ms and the store values (Minimum, Maximum, Average) are updated.

The Average value is calculated by using the previous 5 scheduled read values, if less than 5 reading have been taken since power on or receipt of a "Store Reset" command then the average is calculated using only the available data. i.e. if only 3 records are available they are added together then devided by 3.

Reads the ambient Light (on demand) from the input and returns the value at a resolution of 0.1ma per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the ambient Light stored Average value is returned at a resolution of 0.1ma per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the Minimum ambient Light that has been seen since the "Reset Stores" command was received (or since Power On:- PM = 1), the value at a resolution of 0.1ma per bit in a 16bit number (xx = MSB,yy = LSB).

Reads the maximum ambient Light that has been seen since the "Reset Stores" command was received (or since Power On:- PM = 1), the value at a resolution of 0.1ma per bit in a 16bit number (xx = MSB,yy = LSB).

Resets the stored valus for minimum and maximum to zero (ambient Light), returns 1 if reset was successful, 0 if not successful.

PM = 1

The Sound Signal at the input pin is read on demand and the calculated values are returned using the response message.

Every 100ms a reading of sound volume is taken and the store values (Minimum, Maximum, Average) are updated.

The Average value is calculated by using the previous 5 scheduled read values, if less than 5 reading have been taken since power on or receipt of a "Store Reset" command then the average is calculated using only the available data. i.e. if only 3 records are available they are added together then devided by 3.

Reads the fundamental frequency of the current input signal (on demand) and returns it in the response message at a resolution of xxyy = Frequency in 1hz per bit (xx = MSB,yy = LSB).

Reads the Sound Level (on demand) from the input and returns the value at a resolution of 1 ADC count per bit (xx = MSB,yy = LSB).

Reads the Sound Level stored Average value is returned at a resolution of xxyy = Frequency in 1hz per bit (xx = MSB,yy = LSB).

Reads the Minimum Sound Level that has been seen since the "Reset Stores" command was received (or since Power On:- PM = 1), the value at a resolution of xxyy = Frequency in 1hz per bit (xx = MSB,yy = LSB).

Reads the maximum Sound Level that has been seen since the "Reset Stores" command was received (or since Power On:- PM = 1), the value at a resolution of xxyy = Frequency in 1hz per bit (xx = MSB,yy = LSB).

Resets the stored valus for minimum and maximum to zero (Sound Level), returns 1 if reset was successful, 0 if not successful.

Reads the frequency and volume of the current input signal (on demand) and returns it in the response message according to the table below.
