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.
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
-> 9SCLK_PIN
-> 8XRES_PIN
-> 4TARGET_VDD
-> 11
Run the code and check serial output.
Tested and working with Arduino Uno and CY8C21434.
