hi guys help me on this. i have some display i want reverse engineering to matrix scrolling letter.
its 7x5 2 inc x 1. 5 inc size bi colour matrix (green, Red) hook to MM5450 chip (2 matrix to 0ne chip. manage to find Clk pin, Data Pin, power
i run test code its random come out 3 colours and overload the chip.
anyone can help me on codes to run any scroling letters or msg? thank you
there is no one work on this chip codes in internet. great help guys

For a sipo shift register why the clock is common to all d-flip flops? Shouldn't the clock signal be cascaded from 1st flipflop to 2nd to 3rd and so on. then only we can say bits are shifting one after other. If clock pos edge reaches all d-flip flops at same time output of all flip flops change at a time instead of shifting one after other? Please clarify

GreatScott! i have seen a matrix made out of normal light bulbs showing scenes from movies. it was very beautiful and wanted to recreate that ever since with. small bike lights or something. did you ever come across a project like that or would know how to start on it?

Hi,
The motor says 'biggest thrust (g/s) - 1265/4' does that mean if I use 4 motor the total thrust generated will be 1. 2kg or the one motor will generate that much thrust
I know it's not related to the video but plz help me

The D flip flop has 4 NAND gates? Um, wasn't it 2 XOR and 2 AND gates? That's how I knew it worked! (D flip flop is a more advanced version of an enable controlled RS NOR latch right)

do you have a video regarding suggested equipment for workbench? Your preference in terms of soldering iron, oscilloscope, amp probe, multi meter, capacitance meter etc etc etc?
