How to use ROHM LB202VL (on BP-006LH-GC board) with Arduino?

Using Arduino Displays

Hi,

I got this 8-unit, 7-segment, 2-digit display board with 24 pins and I am wondering how I can interface with this from my Arduino Uno.

The board is labeled ROHM BP-006LH-GC and it has 8 units of the LB202VL LED display. Please see these photos of the board:

I found the datasheet for the LB202VL unit and I have been trying to make an independent unit on the board to work but I haven't been successful in setting its display.

The datasheet for the LB202VL unit can be found here: http://pdf.datasheetarchive.com/datasheetsmain/Datasheets-27/DSA-525461.pdf

Can anybody help me explain how I can work with this and set the display from my Arduino? After having attempted a few times I feel a little lost with this so any help would be greatly appreciated!

Hi Sebastian,
I got the BP-006LH-GC up and running with the arduino. This post got me started:

The code is a bit confusing. The trick is to set the the segments (using the solder points on the back of the board, common for all digits) then light up one digit (using the pins on the edge of the board).

Get in touch if you need more info :slight_smile:
