It’s this simplicity that makes SPI fast. While asynchronous serial communications can run in the hundred-of-thousands of bits per second, SPI is usually good for ten megabits per second or more.

The Statistical Performance Indicators (SPI) is a framework of 5 pillars and 22 dimensions to assess the maturity of national statistical systems. The matrix below provides definitions of each pillar ...

In a 595, bits for each position in the register are sent over one at a time. Most microprocessors have an Serial Peripheral Interface, and using an SPI bus means a lot less mucking about.

Reliable, usable, high-quality statistics are vital for global prosperity and progress. The Statistical Performance Indicators (SPI) provide an open-source framework for assessing the performance of ...
