Ilo juon COB module driver IC eo ej jijet ion juon PCB, im board eo ekkā an bōk jikin einwot juon carrier ñan drive circuit eo. Elaplok jikin ion jen joñan an armij ro kajerbale.

Ewōr jikin ilo PCB eo

Ilo juon COB module driver IC eo ej jijet ion juon PCB, im board eo ekkā an bōk jikin einwot juon carrier ñan drive circuit eo. Lale jikin eo ej bed wot, im juon men emman emaron in walok: juon MCU emaron in likūt, ibben juon real-time clock, flash, temperature sensor, backlight driver im level shifters; meñe jet circuit ko repidodo remaroñ in fold in. Module eo ej etal jen display component ñan display control board.

Menin ejjab kobaiktok ñan an make. Jerbal in hardware ko redik rej dik wōt jikin board eo, eobrak kin BOM ko reaitok im elap assembly step ko. Jerbal in kōmman ko rej maroñ in kobaiktok ilo module eo ej kōjparok jikin board eo, wōnan component eo im juon jerbal in kobaik — juon tokjen emol ñan juon men eo edik wōnan.

Elaplok tokjen jen kobaik hardware ej firmware. Display driver, font library im command parsing remaroñ aolep burned ilo module eo, innem host eo ej aikuj in jilkintok juon instruction — kwalok character eo ilo row jilu, draw juon icon, adjust brightness eo — innem screen eo ej kwaloke. Ejelok font programming ilo host eo, ejelok frame-buffer logic, ejelok inebata kin ien scanning.

Jerbal in oktak in ej alikar ilo MCU ko redik im edik aer kōmman. Elōñ controller ko redik wōnāer rejjab maroñ in bōk juon frame buffer ilo RAM, im likit rendering ilo host side ej kōmman bwe design eo en lukkun nana.
