AN44168 - PSoC® 1 Device Programming using External Microcontroller (HSSP)

AN44168 shows you how to implement PSoC® 1 device programming with an external microcontroller by using modular C code. In this process, called Host Sourced Serial Programming (HSSP), the host microcontroller programs PSoC 1 through the In-System Serial Programming (ISSP) interface. The C code is written so that it can be ported to any microcontroller with minimal changes, speeding up HSSP application development for PSoC 1. The code is built based on the programming procedure explained in the PSoC 1 ISSP Programming Specifications.
