sino ang may schematic o design nito? kailangan ko lang na mapatakbo ang 20-50 characters sa matrix display. kailangan kong schematic yung walang microcontroller.
Pwedeng gawin ng walang micro ito, kaya lang sigurado sasakit ulo mo.
puwedeng puwede itong gawin... kahit walang microcontroller puwedeng puwede....BEAMer ka bA? [tanong ko lang kasi ako BEAMer din ako]... tanong ko lang:1. ilang matrix display ang gagamitin mo?2. at bakit 50 characters? ang english alphabet ay may 26 characters at numbers from 0-10... less than 50 lang ata to.. [gagamit ka ba ng special characters?]-creedcradle
tama c sir glenjoy. nkakita nako nyan nun sa school namin. d gumamit ng micro, pero yung pyesa sangkatutak, tinitingnan mo pa lang sasakit na ulo mo. pero it worked. project ata yun sa electromag kay soriano.
This can be done without a microprocessor. I was planning even to make one just to prove a point.To do this, you need an EPROM, a clock, shift registers, an address generator (CD4040 or likes), a line selector (CD4017) and some glue-logic gates. The EEPROM is pre-proprammed with the moving patterns that is pre-computed on a PC and burned in it.But using a microprocessor is much easier to do.
