As the subject line indicates, i have a rather special 7-Seg display module that has 4 digits, a time " : ", and 10 additional LEDs (5 top, and bottom)
I would like help with altering the library to use with this module. I'm currently using an ICM7228A in conjunction with an arduino pro-mini, but because of the oddities of the module, getting it to function correctly is a bit beyond my scope of knowledge.
Any help would be much appreciated!!
Additional Information:
As i don't have access to a datasheet (i've tried googling the part number HXDF-4047BHG-01 printed on the side, but have had no luck)
I mapped out each pin to each LED, and have included an image that shows front and back image of the module, as well as an image depicting the pin-to-segment mapping, and polarity (it's common anode)
Hello Andy. I am trying to use your library to work with ICM7228C chip connected to 5 positions 7 segments LED. Unfortunately cannot make it work. Hardware connected with Aquino Uno and I tested it without any library sending digits directly . It works fine so I am pretty sure that HW is OK. When I am employing library it does not make any effect.
Would you, please, suggest any troubleshooting steps.
