Programming the SPI

This page discusses a project currently under development. Please be aware that information on this page may change as the project progresses.

ADC/Temperature Sensor Integration

The ADC (AD7928) and Temperature Sensor (AD7314) communicate over very similar, SPI-like interfaces. From this arose the idea of merging the controllers for these chips into a single module in the FPGA.

---

This module aims to merge the ADC and temperature sensor modules into a single module. Both modules communicate over a shared SPI-like bus, and there are many structural and functional similarities between the two. However, this is a partially completed project. The current VHDL files (which are mostly written but need to be tested) can be found at:

• SPI Module.

The subprojects (i.e. earlier versions of the separate ADC and temperature sensor modules) can be found at:

• ADC Module
• Temperature Sensor Module
