Thanks for sharing your project with us. Could you give more details on the control board?

I am attaching a Troubleshooting FAQ’s I found for this power supply. It summarizes the 150 pages of an old thread into a single document. Hope this helps get some questions answered.

You will have to open the Eagle schematic with the software and then you will see that the values are linked to the reference number of the parts. This way it will be easy to identify.

This is the basic connection of BMS charger circuit. Do you need the scheme for the charger it self maybe?

Thanks for sharing this project. I just edited it a bit, so code would look better.

You may check this blog for a revised version of the popular 0-30V PSU: http://www.paulvdiyblogs.net/2015/05/tuning-030v-dc-with-03a-psu-diy-kit.html

Here are two SPICE models found online that will simulate the main IC functions including:- a) bar/dot mode selection, dot mode carry for cascaded ICs, c) resistor-programmed hi/lo reference voltages, d) output current selection, e) non-grounded V- and divider ladder, f) independent V+ and Vled, g) leakage current of outputs, h) segment overlap and i) supply current variation with V+ and Vref output load.
This model is build by user "alec_t" at electro-tech-online.com forum.

How many digital IO lines do you have on your microcontroller? and how many LEDs do you want to drive?

Maybe you can consider casting soft plastic or silicon, i think this would be ideal.

You need to be more specific about your project, so we can help.

yes its looks more better
