12bit Power Supply

[ztoti]

Hi,

I've uploaded to YouTube my new project - 12bit Power Supply with matrix display, PS2 keyboard ( I wrote the subrutine for it as well ). Please take a look, any comments are welcome.

That looks fantastic. Too bad it's Proton Basic though. Thanks for sharing.

Very clever. What LCD did you use?
I have on my bench a Agilent N6705A that has many of he same functions. It only costs the price of a small car.

Hi there,
Thanks for your comment. Anyway I used 128X64 Samsung KS0108 Graphic LCD and matrix keypad which I converted to PS2, or any PS2 numeric keypad.
Cheers

Interesting project.

Are you using PID to control the output voltage?

I'm guessing from the thread title that OP is using an external DAC - so PID is not needed. The MCU's I use have a built-in (dual-channel) 12-bit DAC and I have done something similar. The DAC output is scaled to 2V full scale. An op-amp (rail-to-rail) buffer with 6x gain and a simple linear output stage gives 0-12V output with 3mV resolution.

schematic for this power supply

there is a link in the start of video but it is a dead link :/

I never downloaded the "code". But it seems to just be a sales pitch, from reading the posts: http://www.protonbasic.co.uk/archive...p/t-54946.html

thanks for your help but i need schematic for this power supply and not the code i don't have problem with the code

If you go to that link scale posted and there is a link there where you can donwload the shcematic and PCB

Edit sorry just looked and it's and old version, I did have the schematic but would have to dig deep for it

i am very interesting to this power supply? where I can download schematic of power supply
