I wonder where I can find a list of all defined constants? When I look into the reference (https://energia.nu/reference/) I can only see the following: Constants Floating Point Constants Integer Constants HIGH | LOW INPUT | OUTPUT | INPUT_PULLUP LED_BUILTIN true | false But when I have a look at the examples (https://energia.nu/guide/tutorials/digital/tutorial_button/) I can find PUSH2, GREEN_LED for instance. Where are those constants defined?

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.

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.

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/datas heet/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?

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.

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).
