SPI Master with Signal Path Delay Compensation Reference Design
Texas Instruments
The Programmable Real-time Unit within the Industrial Communication Subsystem (PRU-ICSS) enables you to support real-time critical applications without using FPGAs: CPLDs or ASICs.This reference design describes the implementation of the SPI master protocol with signal path delay compensation on PRU-ICSS. It supports the 32-bit communication protocol of ADS8688 with a SPI clock frequency of up to 16.7 MHz.
Features
- SPI master protocol with adjustable signal path delay compensation (not requiring external hardware for signal path delay compensation)Up to 16.7-MHz SPI clockSupports ADS8688 SPI-communication protocolAutomatic measurement of signal path delay for known secondary responseThis PRU-ICSS firmware has been validated with TIDA-00164 (ADS8688 and ISO7141CC) and contains firmware source code: implementation description and getting started instructions.
Applications
- Analog input module
- Desktop POS
- ATMs (Automated Teller Machines)
- Single board computer
- Mixed module (AI
- AO
- DI
- DO)
- Robot I/O module
- Computer on module
- Condition monitoring module
