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.
