Dual LCD Chess Clock

[a4c8 0]

I'm new into the world of microcomputers and my first idea was to use an Arduino Nano, but then I found out that MSP430 can be programmed in a similar way (Energia) consuming less power while being equipped with an LCD controller.

My question is now which series/model fits my needs. I want to drive 2 LCDs (6 digits each either this [https://www.mouser.de/datasheet/2/244/LCD-S601C71TR-1132196.pdf] or this [https://www.mouser.de/datasheet/2/244/LCD-S601C71TF-1133344.pdf] model) and use some buttons (max 10).

According to Wikipedia I could either use MSP430x1xx, MSP430x3xx, MSP430x4xx, MSP430x6xx or RF SoC (CC430). Which would be the most affordable and least power consuming board?

Have a look at the LaunchPad MSP430FR4133 and MSP430FR6989 with built-in segmented LCD.

The LCD is supported by the native library LCD_Launchpad.

Thanks fot your reply. Your link doesn't seem to work.

But I need to drive two LCDs and according to that picture it's only 1 built-in.

You can combine the LaunchPad with LCD with a second LCD. 

The MSP-EXP430FR4133 with LCD goes for USD14 while the MSP-EXP430FR2433 is USD10.

The larger MSP-EXP430FR6989 with LCD is USD18 vs. USD16 for the MSP-EXP430FR5969.

If power consumption is critical, why not consider an e-ink screen? Pervasive Displays have a wide range of displays, B&W and also tri-colours with red. All are supported with an Energia library.

At this state, we need to know more about your project.

And no need to double post your question at Which MSP430 to pick? Advice please. This is against netiquette: see Netiquette for Newbies.

There is no need to double post your question at Hello from good old Germany.

This is against netiquette and confuses possible answerers. Please see Netiquette for Newbies.

The problem is that not everybody is reading the hello-section, that's why I opened a new thread in the appropriate MSP430 forum.

@Mod: Can you move this thread to MSP430  and rename it to "Which MSP430 can drive two LCDs?" Thanks!

I want to build a chess clock, that's why I need two identical displays. And I want to read the clocks immediately, that's why they have to be bigger. And I can't benefit from e-ink,  because i need to refresh the screens regularly.

Ok, so please change the title of your post for e.g. Dual LCD Chess Clock.

Sorry for the late reply, I've been quite busy recently.

My question is whether (and how) I could use the embedded/integrated LCD controller of MSP430x1xx, MSP430x3xx, MSP430x4xx, MSP430x6xx or RF SoC (CC430) to drive two external LCDs and which specific model would suit my needs best.

Or do I need to use shift registers to achieve what I want? In that case which MSP430 would be best?

Thanks in advance.

Or is there a which-MSP430-to-chose-page? I couldn't find any.
