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.
The source code provided can be easily ported to any microntroller used as the host in the system. However, the application note does not describe the programming protocol. For details on programming protocol, please refer to the following documents:
- PSoC1 – Device programming specifications (AN2026A) – ISSP programming specifications for following device families: CY8C21x23, CY8C21x34, CY8C23x33, CY8C24x23A, CY8C27x43, CY8CTMG110, CY8CTST110
- PSoC1 – Device programming specifications (AN2026B) – ISSP programming specifications for following device families: CY8C21x45, CY8C22x45, CY8C24x94, CY8C28xxx, CY8C29x66, CY8CTST120, CY8CTMA120, CY8CTMG120, CY7C64215
