Kufotokozera Kwambiri
FES4335U1-56T ndi yotsika mtengo, yogwira ntchito kwambiri komanso yanzeru ya gawo lowongolera la TFT-LCD lomwe limatha kupereka zilembo kapena zojambula za 2D mkati mwa 768KB yophatikizidwa ya RAM.
FES4335U1-56T imapereka mawonekedwe a serial (Uart-TT) kuti akhazikitse kulumikizana kwa Hardware ndi MCU yosavuta yakunja (monga 8051 etc.), ndikupereka "Commands Table" pakuyimba ndi kuchita.
Malinga ndi "Commands Table" ya zithunzi za APIs, MCU yakunja imangofunika kutumiza malamulo ogwirizana ndi magawo mu FES4335U1-56T pa mawonekedwe a serial. Chotsitsa cholamula mkati mwa FES4335U1-56T chimapita kukakhazikitsa ntchito yojambulira yokha.
FG875D_command_encoder.exe ndi pulogalamu yogwiritsira ntchito pa PC ndipo imapatsa wogwiritsa ntchito kuti azitsatira malamulo osiyanasiyana mu "Commands Table".

Table ya Malamulo
Chonde, onani chikalata “FG875D_Commands Table_vx.pdf”.
Zowonjezera (Malangizo)
Masitepe atatu kuti muwonetse chithunzi chokhazikika pazenera mwachangu kwambiri.
Gawo 1): Kutembenuza chithunzi kukhala .bin file:
Chifukwa cha FES4335's Flash-ROM yomwe imavomereza .bin yokha file cha chithunzi. Chifukwa chake, kupereka zofunikira FG875_BMP_to_Bin.exe zomwe zimatha kusintha chithunzi cha .BMP file mu .BIN file.
(Onani zolembedwa〝FG875_BMP_to_Bin_manual.pdf〞kuti mumve zambiri).
Gawo 2): Kutsegula .bin file ku SPI-FlashROM yamkati (AMIC A25LQ64).
- Pogwiritsa ntchito khodi ya ntchito 0x21 (APIs:FG875D_WriteToSerialROM) kuti mufunike FES4335 kuti ipite kuzinthu zambiri zotumizira deta.tage.
- Pambuyo pobwezeretsa Command code (0x21) kuchokera ku FES4335, ndiye MPU yakunja imaloledwa kutumiza zithunzi molingana ndi kufotokozera kwa protocol ya kuchuluka kwa data-(kulemba) kufalitsa pa gawo 4-2-2. Onani chithunzi (2).
- Njira ina yodumpha ① & ②:
Kumbali ya PC, kuti mugwiritse ntchito pulogalamu yothandiza (FG875D_command_encoder.exe) ndikusankha ntchito (APIs:FG875D_WriteToSerialROM) posankha. Pambuyo pake, pulogalamu yogwiritsira ntchito idzasamalira zonse zokhudzana ndi kulumikizana ndi kuyika chithunzi file mu SPI-FlashROM.
Pankhani ya kugwiritsa ntchito mapulogalamu amtundu (FG875D_command_encoder.exe), chonde onani chikalata “FG875D_Command_Encoder-UsersMenu.pdf”.
Gawo 3): Pogwiritsa ntchito khodi ya ntchito 0x22 (APIs:FG875D_SerialROM_Show_On_Panel) kuti FES4335 iwonetse zithunzi kuchokera mkati mwa SPI_FlashROM kupita kumalo osonyezedwa.
Mwanjira iyi kuwonetsa chithunzi chomwe chingakhale chachangu kuposa kudzaza buffer yowonetsera ndi basi 8051 MCU.
