Lub kov npo GPIO chaw nres nkoj yog txhais hauv touch.h file raws li qhia hauv qab no (siv lub

(STM32F103RCT6 test program as an example)

Yog tias koj siv IO simulation test program, koj tuaj yeem hloov kho qhov tseem ceeb hauv cov kab lus. Txhua tus pin txhais tau hloov pauv thiab tuaj yeem txhais tau tias yog lwm yam GPIO dawb.

Parallel chaw nres nkoj kev sib txuas lus code siv

A. Arduino xeem qhov kev pab cuam thaum uas tig mus chaw nres nkoj kev sib txuas lus code siv

Yog hais tias tus 8-ntsis hom hais txog cov cai siv nyob rau hauv lub mcu_8bit_magic.h file ntawm lub tsev qiv ntawv LCDWIKI_KBV, raws li qhia hauv qab no:

Yog hais tias tus 16-ntsis hom hais txog cov cai siv nyob rau hauv lub mcu_16bit_magic.h file ntawm

LCDWIKI_KBV lub tsev qiv ntawv, raws li qhia hauv qab no:

B. C51 xeem qhov kev pab cuam thaum uas tig mus chaw nres nkoj kev sib txuas lus code siv

Cov cai uas cuam tshuam tau siv rau hauv LCD.c file raws li qhia hauv qab no:

Siv 8-ntsis thiab 16-ntsis cov lus txib thiab 8-ntsis thiab 16-ntsis cov ntaub ntawv sau thiab nyeem

C. STM32 xeem qhov kev pab cuam thaum uas tig mus chaw nres nkoj kev sib txuas lus code siv

Qhov kev xeem STM32 qhov kev sib txuas ntawm qhov chaw sib txuas lus yog siv nyob rau hauv

LCD. file.Lub IO simulation xeem qhov kev pab cuam yog siv raws li qhia hauv qab no:

Ob qho tib si 8 thiab 16-ntsis cov lus txib thiab 8, 16-ntsis cov ntaub ntawv hloov tsheb raug siv.

4. kov npo calibration cov lus qhia

A. Arduino test program touch screen calibration cov lus qhia
Arduino kov npo calibration yuav tsum tau khiav lub touch_screen_ calibration program ua ntej, thiab ces calibrate raws li cov lus qhia. Tom qab calibration dhau lawm, cov calibration tsis tso tawm rau ntawm qhov screen yuav tsum tau sau rau hauv lub cali_ para.h file ntawm lub tsev qiv ntawv LCDWIKI_TOUCH, raws li qhia hauv qab no:

B. C51 xeem qhov kev pab cuam kov npo calibration cov lus qhia
Lub C51 kov npo calibration yuav tsum tau ua rau Touch_ Kho cov khoom xeem (tsuas yog muaj nyob rau hauv qhov kev xeem STC12C5A60S2), raws li qhia hauv qab no:

Tom qab kov calibration dhau lawm, koj yuav tsum tau txuag lub calibration tsis
tso tawm rau ntawm qhov screen hauv touch.c file, raws li qhia hauv qab no:

C. STM32 qhov kev sim ntsuas qhov screen kov cov lus qhia calibration
STM32 touch screen calibration program cia li paub seb puas yuav tsum tau calibration los yog manually nkag calibration los ntawm nias lub pob.

Nws tau suav nrog hauv cov khoom siv tshuaj ntsuam kov. Cov cim calibration thiab calibration tsis tau txais kev cawmdim hauv AT24C02 flash. Yog tias tsim nyog, nyeem los ntawm lub flash. Cov txheej txheem calibration yog raws li qhia hauv qab no:

Common software

Cov txheej txheem xeem no examples xav tau cov zaub ntawm Suav thiab Askiv, cov cim thiab cov duab, yog li siv cov software modulo. Muaj ob hom modulo software:

Cov PCtoLCD2002 modulo software nqis yog raws li nram no:

Dot matrix hom xaiv Tsaus code
xaiv hom modulo hom kev nce qib
Coj tus qauv los xaiv qhov taw qhia (siab txoj hauj lwm ua ntej)
Output tooj system xaiv tus lej hexadecimal
Custom format xaiv C51 hom

Txoj kev teeb tsa tshwj xeeb yog raws li hauv qab no:
