Bridgetek BT81X (815/6) Cov Yeeb Yaj Suab Yuam Txiag (Video Embedded Video Engine)

May 08, 2019

Cov BT81X Series yog ib qho yooj yim los siv nraaj controllers tsom rau ntawm daim ntaub ntawv kos npe los ua kom muaj kev zoo siab tib neeg tshuab Interfaces (HMIs). Nws muaj cov nram qab no nta:


 Advanced Embedded Video Engine (TSWVYIM) nrog high school graphics thiab video playback

 BT815 / 6 functionality muaj xws li kev tswj nraaj, kev tswj lub suab, thiab kev tswj xyuas kov tau.

 Txhawb ntau yam khoom siv los tsim kev tsim qauv siv yooj yim

 Cov txheej txheem ua kom tiav rau cov neeg siv cov txuj ci tsawg los tsim cov kev qhia zoo

 Kev them nyiaj yug Adaptive Scalable Texture Compression (ASTC) kom txuag tau ntau qhov chaw nco rau cov duab loj dua thiab cov duab kos duab

 Txhawb lwm QSPI NOR flash rau 2Gbit khaws thiab nqa duab nruas (duab, font,

widget thiab lwm yam)

 Txhawb 4-xaim xauv npo (BT816)

 Kev them nyiaj yug capacitive screen nrog 5 nti tes taw qhia txog qhov tseeb (BT815)

 Cov cuab yeej hluav taws xob tuaj yeem paub txog cov cim npe kov thiab khiav ntawm lub zog. Muab kev ceeb toom txog li 255 tus cim npe.

 Txhim kho cov txuj ci sketch

 Built-in 12MHz siv lead ua oscillator nrog PLL muab cov khoom siv lub moos mus txog 72MHz

 Txhawb kom siv crystal-tsawg ua haujlwm nrog kev siv lub moos ua kom zoo

 Video RGB cov zis khiav tawm; configurable los txhawb PCLK txog 72MHz thiab R / G / B cov khoom tso tawm ntawm 1 mus rau 8 khoom

 Lub sijhawm cuam tshuam los kho HSYNC thiab VSYNC sijhawm, ua haujlwm rau ntau tus neeg

qhia

 Kev them nyiaj yug rau LCD zaub nrog daws teeb meem mus txog SVGA (800 x 600) thiab cov ntaub ntawv nrog cov ntaub ntawv siv tau (DE) hom los yog hom VSYNC / HSYNC

 Txhawb cov toj roob hauv pes thiab cov kev taw qhia txog portrait

 Cov khoom tso cai tso zis rau cov lus qhia hauv LCD

 Integrated 1MByte graphics RAM, tsis muaj duab ntab RAM xav tau

 Txhawb kev ua si ntawm kev ua si-JPEG encoded AVI yeeb yaj duab

 Mono audio channel tso tawm nrog Sigma-delta tes taws los piav

 Built-in suab synthesizer

 Qhov yoj playback rau mono 8-ntsis linear PCM, 4-ntsis ADPCM thiab μ-Txoj Cai Code coding hom ntawm cov zauv frequencies ntawm 8 kHz mus txog 48 kHz.

 Cov xim uas siv hluav taws xob los ua kom lub cev tsim tsis yooj yim ntawm kev lim dej

 PWM cov khoom tso tawm rau kev teeb pom kev nrig

 Txheej txheem cwj pwm zoo tuaj yeem ua tus nqi qis rau MPU / MCU uas yog siv tus qauv siv SPI interfaces

 Txhawb SPI cov ntaub ntawv nyob hauv ib zaug, hom plaub lossis plaub zaug; SPI moos mus txog 30MHz


 Lub hwj chim tswj kev tswj tau tso cai rau tus ntiv taw muab tso rau hauv fais fab, pw tsaug zog thiab standby lub xeev

 Txhawb nqa I / O voltage ntawm 1.8V rau 3.3V

 Sab hauv qhov ntsuas hluav taws xob khoom 1.2V rau cov tub ntxhais uas muaj digital

 Ua qhov Power-on-reset Circuit
