ADC16bit ADS111x component

A Precision Low power 16Bit I2C ADC 4 channes device with a Programmable comparator

Detailed description

No detailed description exists yet for this component

Examples

Simple example file to generate a two column CSV file that can be loaded into Microsoft Excel or LibreOffice Math.

The CSV Read/Write component is for simulation or App Developer.

For an embedded CSV read write see the File component

CSV Component used with App Developer -> File component: CSV Test AD

The component requires linking to a File component to provide access to the file system for simulation and runtime, this could be the File SD, File RPI or File AppDeveloper components.

Macro reference

Initialise

	Initialise
Sets up the I2C bus ready for communications with the device. Returned value: 0 = Success
- BYTE	Return

SampleSglRaw

	SampleSglRaw

Property reference

	Properties
	Connections
	Device Address
ADDR connects either to the GDN, VDD, SDA or SCL to determing the address of the ADC.
	Channel
Channel selection
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	RDY/ALRT

	Configuation
	Samples Per Sec

	Simulation
	Gain A0
Gain is for simulation only. The hardware ADC gain is set within the function parameter.
	Gain A1
Gain is for simulation only. The hardware ADC gain is set within the function parameter.
	Gain A2
Gain is for simulation only. The hardware ADC gain is set within the function parameter.
	Gain A3
Gain is for simulation only. The hardware ADC gain is set within the function parameter.
	Simulate Comms
Allows the communications to be simulated overriding the value on the panel slider controls.
