74hc597 v1.0
Data acquisition cog reading up to 4 74hc597's in series. A 74hc597 is an 8-bit latch/shift register. It grabs digital inputs in two stages. This cog free runs ...

This object supports the 2 channel LTC1298 sold by Parallax. Documentation and schematic is included in the source code. Best regards, Charlie

The AD7705 and AD7706 are complete 16-bit, low-cost, Sigma Delta ADCs intended for dc and low-frequency ac measurement applications.
An integrated amplifier makes it possible to measure voltages up to ...

Interface to the AD8803 Octal 8-Bit Trim DAC.

The ADC Input Driver (http://obex.parallax.com/objects/488/) does this frequency reading and a lot more. It is also faster and is compatible with more MCP3X0X ADCs.

This PASM-driven object reads values off ...

Driver for MCP3X0X ADCs. 1 to 8 channels, 8- to 16-bits. Functions include programmable input (Schmitt, high/low levels), frequency input, max/min values, averaging, and wait high or low input state.

Interfaces with National's ADC0808 analog to digital converter. Includes my debugger program and suggested connection diagram. If you're in EEE174 at CSUS you can use this code, but Dahlquist will ...
