FORENEX FES4335U1-56T Incwadi Yomsebenzisi Yokulawula Imojuli Yemephu Yenkumbulo

I-FES4335U1-56T iyindleko ephansi, ukusebenza kahle okuphezulu nokukhalipha kwemojuli yokulawula isibonisi ye-TFT-LCD engahlinzeka ngezinhlamvu noma uhlelo lokusebenza lwemifanekiso engu-2D ngaphakathi kokushumekiwe okungu-768KB kokuboniswa kwe-RAM.
I-FES4335U1-56T inikeza isikhombimsebenzisi se-serial (Uart-TT) ukuze kusungulwe ukuxhumana kwehadiwe nge-MCU yangaphandle elula (njenge-8051 njll.), kanye nokuhlinzeka “Ngethebula Lemiyalo” ukuze kushayelwe umphumela wesithombe nokwenza.
Ngokwe-“Commands Table” yama-API wezithombe, i-MCU yangaphandle idinga kuphela ukudlulisa ikhodi yomyalo ehambisanayo namapharamitha ku-FES4335U1-56T phezu kwe-serial interface. I-decoder yomyalo ngaphakathi kwe-FES4335U1-56T izohamba ukuze iqalise umsebenzi wezithombe ngokuzenzakalelayo.

I-FG875D_command_encoder.exe iwuhlelo olusetshenziswa yi-PC futhi ihlinzeka umsebenzisi ukuthi azizwele imiyalo ehlukahlukene yokusebenza kokuthi “Commands Table”.

Isofthiwe

Ukuxhumana (ukuxhawula)

Ngenxa yokuxhumana kwe-serial (Uart-TTL) lezo FES4335 ezinikeze ukusungula ukuxhumana nomsingathi wangaphandle. Umsingathi uyakwazi ukudlulisa ukusakazwa komyalo ku-FES4335 ukuze kwenziwe umsebenzi abuze.

Ngokusho komthamo wokudlulisa, ifomethi yokusakaza yomyalo ichazwa nje ngezigaba ezimbili.

I-Standard Command Stream: Lena ifomethi yokusakaza yomyalo ebalulekile yomsebenzi ngamunye esohlwini Lwethebula Lemiyalo. (Bheka Ithebula Lemiyalo Yesigaba 4-3).
I-Bulk Data Transmission Stream: Nikeza kuphela kweminye imisebenzi ezocela ukudluliswa kwedatha ngobuningi, futhi ukubuza kuqinisekisiwe ngesikhathi sokusakazwa komyalo okujwayelekiletage.
Okwamanje ngaphansi kwemisebenzi emibili kuphela ezocela iphrothokholi Yokudluliswa Kwedatha Yenqwaba.

FG875D_WriteToSerialROM (ikhodi yokusebenza 0x21).
FG875D_ Display _Block_RW (ikhodi yokusebenza 0x24).

NgokweThebula Lemiyalo, umyalo ngamunye unekhodi yokusebenza ehlukile yomsebenzi othile wokusebenza. (Bheka Ithebula Lemiyalo Yesigaba 4-3).
Ngakho-ke, uma i-FES4335 isithole okuphelele kwe-Standard Command Stream futhi iyiphi ingxenye yesheke ehlolwayo kuqala. Ngemuva kwalokho, ingxenye yekhodi yomsebenzi izokhonjwa futhi isetshenziswe kanye nengxenye yepharamitha.

Kukhona indawo yekhodi ethi 0x50~0x5F lapho izonikezela khona ukuchaza ikhodi ethile yomlayezo futhi ihlukaniswe nayo yonke ikhodi yokusebenza.

b. Ngaphandle kokudluliselwa kwedatha ngobuningi stage. I-FES4335 izobuyisela ngokuzenzakalelayo ukuxhumanisa (x,y) kokuthinta lapho kwenzeka ukuphazamiseka kokuthinta.
c. Umsingathi angakwazi futhi ukuvota inani le-coordinate (x,y) ngokuthumela ikhodi Yomsebenzi 0x03 (APIs:FG875D_Detect_Touch).

Umyalo (Sakaza / Ifomethi / iphrothokholi)

I-Standard Command Stream

Ifomethi: Le fomethi ihlanganisa ibhayithi yekhodi yokusebenza kanye namabhayithi epharamitha ambalwa kanye nebhayithi ye-checksum ikhodi.
Protocol:

Ukudluliswa Kwedatha Yenqwaba
Njengoba ikhodi yokusebenza ku-Standard Command Stream ithi (0x21) noma (0x24) ezobuza umsebenzi wokudlulisa idatha ngobuningi ngemva kokuba leyo khodi yokusebenza ikhonjwe yi-FES4335.
Kulokhu, yonke inqubo yokuxhumana izohlukaniswa ibe izigaba ezimbilitages (Standard Command Stream stage + I-Bulk Data Transmission protocol stagfuthi).

Ifomethi: Le fomethi iyatholakala ekudluliselweni kwedatha yenqwaba stage kuphela.
Ikhodi eholayo (0x55,0xAA) izongena esikhundleni sekhodi yokusebenza ukuze ibonise ukuqala kokudluliswa kwedatha eyinqwaba bese inani lisethwa libe yibhayithi yobude kuyaboniswa ukuthi ingakhi i-data byte ezovela ngokuqhubekayo. Isaziso sokusetha i-byte yobude ngenani ledatha yangempela kukhishwe u-1.
Protocol:
Umfanekiso wokukhombisa ukusakazwa komyalo ojwayelekile okucela ukubhala ukuthunyelwa kwedatha yenqwaba ku-FES4335. Umfanekiso okhombisa ukusakazwa komyalo okujwayelekile okucela ukufunda ukudluliswa kwedatha ngobuningi kusuka ku-FES4335.

Sicela, ubheke idokhumenti “FG875D_Commands Table_vx.pdf”.

Isithasiselo (Amathiphu)

Izinyathelo ezintathu zokukhombisa izithombe ezimile esikrinini ngokushesha okukhulu.

Isinyathelo1): Ukuguqula isithombe sibe .bin file:
Ngenxa ye-FES4335's Flash-ROM eyamukela kuphela i-.bin file wesithombe. Ngakho-ke, ukunikeza insiza FG875_BMP_to_Bin.exe ekwazi ukuguqula isithombe se-.BMP file ku-.BIN file.
(Bheka kudokhumenti〝FG875_BMP_to_Bin_manual.pdf〞ukuthola imininingwane).

Isinyathelo2): Iyalayisha .bin file ku-SPI-FlashROM yangaphakathi (AMIC A25LQ64).

Ukusebenzisa ikhodi yokusebenza engu-0x21 (APIs:FG875D_WriteToSerialROM) ukuze udinge i-FES4335 ukuze ingene ekudluliselweni kwedatha ngobuningitage.

Ngemuva kokuthi ikhodi yempumelelo yomyalo(0x21) ibuyiswe isuka ku-FES4335, khona-ke i-MPU yangaphandle izovunyelwa ukudlulisa izithombe ngokuya ngencazelo yephrothokholi mayelana nokudluliselwa kwedatha ngobuningi-(bhala) esigabeni 4-2-2. Bheka umfanekiso (2).
Enye indlela yokweqa ① & ②:
Ohlangothini lwe-PC, ukusebenzisa isofthiwe yokusetshenziswa (FG875D_command_encoder.exe) bese ukhetha into yokusebenza (ama-API:FG875D_WriteToSerialROM) kungxoxo yokukhetha. Ngemuva kwalokho, isoftware yokusetshenziswa izonakekela konke mayelana nephrothokholi yokuxhumana nokulayisha isithombe file ku-SPI-FlashROM.
Mayelana nokusetshenziswa kwesofthiwe yokusetshenziswa (FG875D_command_encoder.exe), sicela ubhekisele kudokhumenti ethi “FG875D_Command_Encoder-UsersMenu.pdf”.

Isinyathelo3): Kusetshenziswa ikhodi yokusebenza engu-0x22 (APIs:FG875D_SerialROM_Show_On_Panel) ukuze kudinge i-FES4335 ukuthi ibonise izithombe ukusuka ku-SPI_FlashROM yangaphakathi kuya endaweni ekhonjisiwe yephaneli.

Ngale ndlela ukukhombisa isithombe esingashesha kunokugcwalisa isibonisi sokubonisa ngebhasi elingu-8051 MCU.
