CMD_SKETCH - Pib Hloov Hloov Tawm Skew

Apr 27, 2019

Tom qab qhov hais kom ua tiav, cov tshuab pa roj carbon monoxide ua haujlwm tsis tu ncua

inputs thiab xim cov xim pixels rau hauv ib lub tiav bitmap, raws li tus kov (x, y). Qhov no txhais tau hais tias

tus neeg siv kov inputs yog kos rau hauv cov bitmap uas tsis tas yuav siv MCU ua haujlwm. Hais kom ua

CMD_STOP nres cov txheej txheem kev kos duab.

Nco ntsoov tias tsuas yog ib qho ntawm CMD_SKETCH, CMD_SCREENSAVER, los yog CMD_SPINNER thiaj ua tau

active ntawm ib lub sij hawm.

Qhov kev hais no yog siv rau FT800 thiab FT801 cov neeg siv raug pom zoo kom siv

CMD_CSKETCH txij thaum lub optimization tau ua rau kev kov capacitive.

C daim ntawv prototype

tsis muaj dabtsis cmd_sketch (int16_t x,

int16_t y,

uint16_t w,

uint16_t h,

uint32_t ptr,

uint16_t hom ntawv);

Cov lus qhia

x

x-coordinate ntawm kos duab sab saum toj-sab laug, hauv pixels

y

y-coordinate ntawm kos duab sab saum toj-sab laug, hauv pixels

w

Dav ntawm thaj chaw sketch, hauv pixels

h

Qhov siab tshaj plaws ntawm kev kos duab, hauv pixels

ptr

Luag qhov chaw nyob ntawm kev kos duab

hom ntawv

Cov qauv ntawm kev kos duab bitmap, L1 lossis L8

Kev piav qhia

Thov nco ntsoov tias hloov tshiab zaus ntawm cov ntaub ntawv teev lus hauv cov cim xeeb ntawm cov duab hauv cov cim xeeb yog nyob ntawm

sampling zaus ntawm ADC built-in circuit ntawm FT800, uas yog txog li 1000 Hz.
