Kev piav qhia dav dav
FES4335U1-56T yog tus nqi qis, kev ua haujlwm siab thiab ntse ntawm TFT-LCD zaub tswj module uas tuaj yeem muab cov cim lossis 2D daim ntawv thov hauv ib qho 768KB ntawm RAM.
FES4335U1-56T muaj serial interface (Uart-TT) los tsim kev sib txuas lus kho vajtse nrog ib qho yooj yim MCU sab nraud (xws li 8051 thiab lwm yam), thiab muab "Cov lus txib" rau kev hu xov tooj thiab ua tiav.
Raws li "Commands Table" ntawm cov duab APIs, sab nraud MCU tsuas yog yuav tsum tau xa cov lus txib sib txuas nrog cov kev txwv rau hauv FES4335U1-56T dhau qhov sib txuas sib txuas. Cov lus txib decoder sab hauv ntawm FES4335U1-56T yuav mus siv cov duab ua haujlwm los ntawm kev ua haujlwm.
FG875D_command_encoder.exe yog PC's software utility thiab muab rau cov neeg siv kom paub txog ntau yam haujlwm commands hauv "Commands Table".

Kev sib txuas lus (kev sib koom tes)
Vim yog cov serial interfaces (Uart-TTL) cov FES4335 tau muab los tsim kev sib txuas lus nrog tus tswv tsev sab nraud. Tus tswv tsev muaj peev xwm xa cov kwj mus rau FES4335 rau kev thov ua haujlwm.
Raws li lub peev xwm ntawm kev sib kis, cov lus txib kwj hom tsuas yog txhais ua ob pawg.
- Standard Command Stream: Qhov no yog ib qho tseem ceeb hais kom ua kwj hom rau txhua txoj haujlwm uas tau teev tseg hauv Cov Lus txib. (Saib Tshooj 4-3 Cov Lus txib).
- Bulk Data Transmission Stream: Tsuas yog muab rau qee txoj haujlwm yuav nug kom xa cov ntaub ntawv ntau, thiab qhov kev nug tau lees paub thaum lub sijhawm tus qauv hais kom ua kwj.tage.
Tam sim no tsuas yog hauv qab ob txoj haujlwm uas yuav thov rau Bulk Data Transmission raws tu qauv.
- FG875D_WriteToSerialROM (ua haujlwm code 0x21).
- FG875D_ Zaub _Block_RW (function code 0x24).
Raws li cov lus txib, txhua qhov hais kom ua muaj cov lej ua haujlwm tshwj xeeb rau kev ua haujlwm tshwj xeeb. (Saib Tshooj 4-3 Cov Lus txib).
Yog li ntawd, ib zaug FES4335 tau txais kev ua tiav ntawm Standard Command Stream thiab qhov twg ntawm checksum raug kuaj ua ntej. Tom qab ntawd, lub luag haujlwm code ib feem yuav raug txheeb xyuas thiab siv nrog rau ntu ntu.
Muaj qhov tshwj xeeb code cheeb tsam 0x50 ~ 0x5F qhov twg yuav mob siab rau txhais qee cov lus code thiab tseem raug cais tawm ntawm tag nrho cov haujlwm code.
| Rov qab cov lus code | ASCII | xis hex | Kev piav qhia |
| Tsis yog code | “X” | 0 x 58 | Checksum yuam kev |
| Tos code | “W” | 0 x 57 | FES4335 tsis khoom |
| Npaj code | "S" | 0 x 53 | FES4335 yog npaj txhij |
| Timeout code | “T” | 0 x 54 | Txais Timeout |
| Kov Interrupt code | “P” | 0 x 50 | Kov vaj huam sib luag tau kov |

- Ib txoj cai tshwj xeeb los qhia txog kev cuam tshuam kov tau tshwm sim thiab tseem yuav rov qab qhov kev sib koom tes (x, y) tus nqi ntawm lub vaj huam sib luag tau txais.
- Rov qab kov cuam tshuam code (0x50) nrog kev tswj hwm (x,y) tus nqi zoo li hauv qab no,
- a. Nyob rau hauv ib tug tej ntaub ntawv kis tau tus mob stage, FES4335 yuav ua haujlwm ib ntus kom tsis txhob kov lub luag haujlwm thiab nres rov qab qhov kev sib koom tes (x, y) ntawm kov.
- b. Tawm ntawm cov ntaub ntawv ntau kis stage. FES4335 yuav cia li xa rov qab qhov kev sib koom tes (x, y) ntawm kev kov thaum muaj kev cuam tshuam kov tau tshwm sim.
- c. Tus tswv tsev kuj tseem tuaj yeem xaiv qhov kev sib koom tes (x, y) tus nqi los ntawm kev xa Function code 0x03 (APIs: FG875D_Detect_Touch).
Hais kom ua (kwj / hom / raws tu qauv)
Standard Command Stream
- Hom ntawv: Hom ntawv no sib txuas ua ke ib byte ntawm cov lej ua haujlwm thiab ob peb qhov kev ntsuas bytes thiab ib byte ntawm checksum code.
- Raws tu qauv:
Kev xa cov ntaub ntawv ntau
Txij li cov lej ua haujlwm hauv Standard Command Stream yog (0x21) lossis (0x24) uas yuav nug ntau cov ntaub ntawv xa mus ua haujlwm tom qab cov lej ua haujlwm tau txheeb xyuas los ntawm FES4335.
Hauv qhov no, tag nrho cov txheej txheem kev sib txuas lus yuav raug muab cais ua ob stages (Standard Command Stream stage + Bulk Data Transmission raws tu qauv stagthiab).
- Hom ntawv: Hom ntawv no yog muaj rau tej ntaub ntawv kis tau tus mob stage xwb.
Tus lej code (0x55,0xAA) yuav hloov cov lej ua haujlwm los qhia txog Bulk Data Transmission pib thiab tom qab ntawd tus nqi yuav raug teeb tsa mus rau qhov ntev byte yog qhia tias pes tsawg cov ntaub ntawv byte yuav los mus tas li.

Appendix (Cov Lus Qhia)
Peb kauj ruam los ua kom pom cov duab tseem ntawm qhov screen sai dua.
Kauj ruam 1): Hloov cov duab rau .bin file:
Vim yog FES4335's Flash-ROM uas tsuas yog txais .bin file ntawm duab. Yog li ntawd, muab cov khoom siv hluav taws xob FG875_BMP_to_Bin.exe uas muaj peev xwm hloov tau .BMP duab file hauv .BIN file.
(Saib rau cov ntaub ntawv 〝FG875_BMP_to_Bin_manual.pdf〞 kom nthuav dav).
Kauj ruam 2): Loading .bin file mus rau sab hauv SPI-FlashROM (AMIC A25LQ64).
- Siv cov lej ua haujlwm 0x21 (APIs: FG875D_WriteToSerialROM) kom xav tau FES4335 mus rau hauv cov ntaub ntawv xa tawm ntau.tage.
- Tom qab hais kom ua tiav txoj cai (0x21) rov qab los ntawm FES4335, tom qab ntawd MPU sab nraud raug tso cai xa cov duab raws li cov txheej txheem piav qhia txog cov ntaub ntawv ntau-(sau) xa mus rau ntu 4-2-2. Saib daim duab (2).
- Lwm txoj hauv kev hla ① & ②:
Ntawm PC sab, kom ua tiav cov khoom siv hluav taws xob (FG875D_command_encoder.exe) thiab xaiv cov khoom ua haujlwm (APIs: FG875D_WriteToSerialROM) hauv kev xaiv dialog. Tom qab ntawd, tus nqi hluav taws xob software yuav saib xyuas txhua yam ntawm kev sib txuas lus raws tu qauv thiab upload duab file mus rau SPI-FlashROM.
Hais txog kev siv cov khoom siv hluav taws xob (FG875D_command_encoder.exe), thov mus saib cov ntaub ntawv "FG875D_Command_Encoder-UsersMenu.pdf".
Kauj ruam 3): Siv cov lej ua haujlwm 0x22 (APIs: FG875D_SerialROM_Show_On_Panel) kom xav tau FES4335 los tso saib cov duab sab hauv SPI_FlashROM mus rau qhov chaw qhia ntawm lub vaj huam sib luag.
Los ntawm txoj kev no los qhia cov duab uas yuav nrawm dua li sau cov duab tsis pom los ntawm 8051 MCU tsheb npav.
