I really want to daatasheet a simple alarm clock for my girlfriend’s birthday, day after thanksgiving: I have been trying to get this to work for about three days now.
I first tried using a MSPF, but decided to switch to arduino for ease of use. Please check my code and tell me if I am doing this right.

Details about the VFD screen. Same size as register. Now, here is the problem.
My VFD displays nothing. No backlight, no symbols, nothing. Can someone please help me with this?
I checked everything by now Here is my source catasheet Can anyone please give me any hint as to what could be the problem? Shouldn’t this be the same as using a LCD with 8bit register?
How do you have the arduino connected to the display and how are you powering the display?
The data sheet says you need to have a supply that can supply at least ma at startup, do you? Yep, the power supply should be up to the job.

It’s a big DC thingy with two knobs, and it can supply up to 3Amps 25V. The power pins are connected to the breadboard for both the VFD and the hc00a.
I’d take a picture but I daatsheet have a camera better than 2megapixels: Is there a ground connection shared between the two? Just curious, why bit-bang it instead of using the Wire library that handles I 2 C?
I’ll guess that’s ported MSP code I managed to get an oscilloscope today. Now I want to check if my board is on, so how would I go about checking for that? Should I check if there is a signal from the register to the controller or the controller to the LCD?

To test with datashewt oscilloscope one channel or two? Then look at the data, does it waggle about. If you can look at two signals at the same time does the data waggling only occur when the clock is going.
Are the levels good? If so it’s down to the software either in the way you are sending it or what you are sending. I notice satasheet comments say send AAA and you are sending a bit pattern that I can’t interpret as A in any way.
