PSoC 5, 3 & 1

Anybody know if the PSoC1 Miniprog1 will have enough drive to program via opto-couplers. I have isolated all IO lines to the outside world with CNY17-4 opto's and would like to program the PSoC using the connector to the outside.

Hello Chris,

   

Firstly, Miniprog1 lines do not have enough strength to drive the diodes of opto-couplers. Secondly, the ISSP data line is bi-directional, and creating an opto-coupler wall will be difficult.
