Miniprog used to program device running at 3.3V

Questions about programming (not codeing) PSoCs and Encore II as well as freeware programming hardware and software are discussed here. This is also the place to talk about production programming. Programming means loading a HEX file in to the Flash, not, writing your program.

Miniprog used to program device running at 3.3V

Postby Borkhuis » Wed May 01, 2013 12:24 am

One of the PSoC1 devices we use is mounted on a board that only supplies 3.3V. This power supply cannot be removed to program the device. The ISSP lines and reset line are available to the programmer, but I left out the Vdd line, as the board itself supplies the power. Can I use the MiniProg device to program this device (using the Reset mode)?

I found the following article, describing a modification to the MiniProg, to allow 3.3V operation.
How to set MiniProg1 to power 3.3V?

Is this needed to when not using the Vdd to power the device?
