txoj cai ua haujlwm
Taw qhia rau SH1107 Controller
SH1107 yog OLED / PLED maub los uas txhawb nqa qhov kev daws teeb meem siab tshaj plaws ntawm 128 * 128 thiab 2048-byte GRAM. Kev them nyiaj yug 8-ntsis 6800 thiab 8-ntsis 8080 parallel chaw nres nkoj cov ntaub ntawv tsheb npav, kuj txhawb nqa 3-xaim thiab 4-xaim SPI serial tsheb npav thiab I2C tsheb npav. Txij li thaum tswj kev sib txuas yuav tsum muaj ntau qhov chaw nres nkoj IO, feem ntau siv yog SPI serial tsheb npav thiab I2C tsheb npav. Nws txhawb nqa ntsug scrolling thiab tuaj yeem siv rau hauv cov khoom siv me me xws li xov tooj ntawm tes, MP3 players thiab ntau dua. SH1107 maub los siv 1 me ntsis los tswj cov pixel zaub, yog li txhua pixel tuaj yeem tso saib dub thiab dawb lossis dub thiab xiav. Cov duab RAM tau muab faib ua 16 nplooj ntawv, nrog 8 kab ib nplooj ntawv thiab 128 pixels ib kab. Thaum teeb tsa pixel cov ntaub ntawv, koj yuav tsum tau qhia cov nplooj ntawv chaw nyob ua ntej, thiab tom qab ntawd qhia cov kab qis qhov chaw nyob thiab kab qhov siab qhov chaw nyob raws, yog li teem 8 pixels nyob rau hauv txoj kab ntsug tib lub sijhawm. Txhawm rau kom muaj peev xwm tswj tau cov ntsiab lus pixel ntawm txhua txoj haujlwm, software thawj zaug teeb tsa lub ntiaj teb ib-dimensional array ntawm qhov loj tib yam li cov duab RAM, thawj daim duab qhia cov pixel taw tes cov ntaub ntawv mus rau lub ntiaj teb array, thiab cov txheej txheem siv lub LOSSIS lossis kev ua haujlwm los xyuas kom meej tias lub ntiaj teb array tau sau ua ntej. Cov ntaub ntawv tsis yog corrupted, thiab cov ntaub ntawv ntawm lub ntiaj teb no array yog ces sau mus rau lub GRAM kom nws yuav tsum tau tso tawm los ntawm OLED.
Introduction to IIC Communication Protocol
Cov txheej txheem ntawm kev sau cov ntaub ntawv ntawm lub tsheb npav IIC tau qhia hauv daim duab hauv qab no:
Tom qab lub tsheb npav IIC pib ua haujlwm, qhov chaw nyob tus qhev raug xa mus ua ntej. Tom qab tau txais cov lus teb ntawm qhev, nws mam li xa ib qho kev tswj xyuas los qhia rau tus qhev ntaus ntawv seb cov ntaub ntawv txuas mus ntxiv yog xa mus rau IC sau npe lossis sau. Cov ntaub ntawv RAM, tom qab tau txais cov lus teb tus qhev, ces xa tus nqi ntawm ntau bytes kom txog thaum kev sib kis tiav thiab IIC tsheb npav nres.
ntawm lawv:
C0 = 0: Qhov no yog qhov kawg tswj byte, thiab tag nrho cov ntaub ntawv bytes xa hauv qab no yog tag nrho cov ntaub ntawv bytes.
- C0 = 1: Qhov thib ob bytes xa mus yog cov ntaub ntawv byte thiab lwm tus byte tswj.
- D/C(——)=0: yog tus sau npe hais kom ua haujlwm byte
- D/C(——)=1: ua hauj lwm byte rau RAM cov ntaub ntawv
Daim duab IIC pib thiab nres lub sijhawm yog raws li nram no:
Thaum cov ntaub ntawv kab thiab kab moos ntawm IIC ob qho tib si khaws cia nyob rau theem siab, IIC nyob rau hauv lub xeev tsis ua haujlwm. Lub sijhawm no, cov ntaub ntawv kab hloov pauv los ntawm qib siab mus rau theem qis, thiab cov kab moos tseem nyob rau theem siab, thiab IIC tsheb npav pib xa cov ntaub ntawv. Thaum cov kab moos tuav tau siab, cov ntaub ntawv kab hloov ntawm qis mus rau siab, thiab IIC tsheb npav nres cov ntaub ntawv xa mus.
Daim duab lub sijhawm rau IIC xa cov ntaub ntawv me ntsis yog raws li hauv qab no:
Txhua lub moos pulse (tus txheej txheem ntawm rub siab thiab rub qis) xa 1 me ntsis ntawm cov ntaub ntawv. Thaum lub moos kab siab, cov kab ntawv cov ntaub ntawv yuav tsum nyob ruaj khov, thiab cov ntaub ntawv kab raug tso cai hloov thaum lub moos kab qis.
ACK kis tau tus mob lub sij hawm daim duab yog raws li nram no:
Thaum tus tswv tos ACK ntawm tus qhev, nws yuav tsum ua kom lub moos siab. Thaum tus qhev xa ACK, khaws cov ntaub ntawv qis.

Ncaj qha hloov IIC_SLAVE_ADDR(default yog 0x3C (xws li 0x78)). Rau example, hloov mus rau 0x3D, ces qhov chaw nyob IIC qhev yog 0x3D (xws li 0x7A);
- STM32 thiab C51 xeem qhov kev pab cuam IIC hloov los ntawm qhov chaw nyob ntaus ntawv
Tus qhev ntaus ntawv chaw nyob ntawm STM32 thiab C51 qhov kev xeem IIC yog txhais hauv iic.h file, raws li qhia hauv daim duab hauv qab no:
Ncaj qha hloov IIC_SLAVE_ADDR (default yog 0x78).For example, hloov mus rau 0x7A, ces qhov chaw nyob IIC qhev yog 0x7A.

C51 xeem qhov kev pab cuam IIC kev sib txuas lus code yog siv nyob rau hauv iic.c, raws li qhia hauv qab no:
Common software
Cov txheej txheem xeem no examples yuav tsum tso saib Suav thiab Askiv, cov cim thiab cov duab, yog li PCtoLCD2002 modulo software siv. Ntawm no, qhov teeb tsa ntawm modulo software yog piav qhia tsuas yog rau qhov kev sim ntsuas. PCtoLCD2002 modulo software nqis yog raws li hauv qab no: Dot matrix hom xaiv Tsaus code lub modulo hom xaiv qhov kev vam meej (C51 qhov kev pab cuam yuav tsum tau xaiv determinant) Coj tus qauv xaiv cov kev taw qhia (qhov siab ua ntej) (C51 qhov kev xeem yuav tsum xaiv thim rov qab (tsawg txoj hauj lwm ua ntej)) Cov lej tso zis xaiv tus lej hexadecimal Kev cai xaiv hom C51 hom Kev teeb tsa tshwj xeeb yog raws li hauv qab no:
