Cypress PSoC® 1 Device hacking using an Arduino

This is a fork of the original port of the code found at http://www.cypress.com/?rID=2906 (AN44168, Revision 2.30) to the Arduino platform by Dirk Petrautzki.

Besides implementing the standard commands for flashing a PSoC, it includes the following extra commands:

  • Cmnd_STK_READ_REG 0x79
  • Cmnd_STK_WRITE_REG 0x80
  • Cmnd_STK_READ_MEM 0x81
  • Cmnd_STK_WRITE_MEM 0x82
  • Cmnd_STK_EXEC_OPCODES 0x83
  • Cmnd_STK_RUN_CSUM 0x84
  • Cmnd_STK_START_CSUM 0x85
  • Cmnd_STK_READ_SECURITY 0x86

Which are very helpful to dump the protected flash of the PSoC.

Usage

Clone the code into a folder called 'arduino_hssp', run make && make_upload

Connect your PSoC 1 device as follows (can be changed in issp_defs.h):

  • SDATA_PIN -> 9
  • SCLK_PIN -> 8
  • XRES_PIN -> 4
  • TARGET_VDD -> 11

Run the code and check serial output.

Project status

Tested and working with Arduino Uno and CY8C21434.
