Subject: Re: More I2C fun

Hi Dave,

I was very impressed with your design for a 16 knob programmer for the PSIM using I2C
chips.

I think others in this group could benefit from this.

I will start a survey:

How many people would like a dedicated 16 knob programmer for the PSIM?

If there is enough interest, perhaps it may be worth spinning a PC board. Please note this
is not Wiard related, my interest is as a part of the user group.

Thank you again for all your hard work and talented engineering.
