Hi Abhi,

Sorry for saying so, but you're more or less.... asking for a tire, without mentioning what car you drive. :slight_smile:

I haven't encountered much 12x16 displays, they may be available/buildable, countless different displays exist though and it probably is easier to get an answer to your question if you give the reader a bit more info.

Did you buy it and if so, could you provide some links with more info ?
If you built it yourself, could you give more info / a schematic ?

Geez, I created a schematic for you yesterday. Have you tried writing any code yourself yet?

Dear Sir,

I will write the code and let you know.

Thanks,
Abhi

hi everyone,

i am new on this forum...i am working on 24*16 RGB LED matrix with HT1632C display driver.... designed my PCB and populated with componets... i want to ask about pin connection between Arduino Mega and HT1632C...any help please? thanks in advance

Arduino ht1632c

SDA connects to DATA on ht1632c
SCL connects to ?
? connects to WR on ht1632c
? connects to RD on ht1632c
? connects to CS on ht1632c

Hi and welcome.

You should start a new thread for your question. Asking your question on someone else's thread is considered a little rude.

I do not think the ht1632c chip has an i2c interface, so using SDA abd SCL is not correct. The SDA and SCL pins are also general purpose i/o pins (20 and 21 on the Mega I think) so you could use them for this, but you would then not be able to connect any i2c devices to your circuit such as an rtc (real time clock).

Here is a tutorial that should help with the wiring.

Well, not so much "rude", as it makes no sense to say people "own" threads or are being importuned in any way and indeed not infrequently the discussion becomes diverted in all sorts of ways in any case, not necessarily unprofitably. :grinning:

What the problem is, is that you have appended to the wrong thread, asking about a 24 by 16 matrix with a HT1632C, when the OP titled this for a 16 by 12 which would anticipate different drivers, so you are not so readily going to get the answers most applicable to your particular situation. It is in this regard, inappropriate.
