Hi everyone, I'm Jacob Cheng from China, working in an electronic instrument manufacturer, and this is not a promotion content, I'm here asking for help.
As a freshman of marketing promotion in the electronic instrument, I have no idea about what topic will engineers interested in. So, I'm here today to ask for a little (...)

Nobody is going to do your homework for you.
If you have a specific question then ask that question, instead of asking someone to help you.

Running LCD parallel interface through ribbon cable means asking for trouble. Connecting LCD ground or display frame to chassis metal must be absolutely avoided, it might help to place a small capacitor between E pins and ground at the display. You can also verify command and data register writes by read-back and reinitialize the display in (...)

You are writing to the display controller with all the processing power you have.
Maybe 100000 times per second.
It's like I'm asking you 100000 questions in a second, but don't give you time to think about my question and give you no time to respond....
And what's the idea behind writing the same values in a loop?

Please help me to provide GDSII file of simple inverter that will contain at least one transistor.
Why is it so difficult to build one for yourself rather than asking around and waiting?
It is just a simple inverter after all...
Assumption: You have access to the relevant tools!

Yes, that is correct but there may be a more fundamental problem here.
You are asking for Caller Identification, the designs so far are DTMF decoders, if you are looking to find out where a call originated from (the callers number via landline), a different protocol is used and it is also different from one Telco to another.

Oh, Digikey has some that cost over $100.00US each.

There's also a lack of specification. You are asking for 7.5 kW motor inverter but showing a three-phase bridge with 300 V bus voltage in your first post. This would refer to a 230V (actually only 210V) motor which is rarely made up to 7.5 kW power.

Are you asking us for help to read the specification of your instrument?
It's specified with < 1.5 ms "response time" (10/90% rise time). Technically, it's a switched mode power supply with recuperation, so it surely involves output inductors and filter capacitors. If you want considerable faster rise/fall time, use a purely analog (...)
