——I tiritiri mai i a DWIN Froum

Ma te whakamahi i te maramara DWIN T5L1 hei matua mana o te miihini katoa, ka whiwhi me te tukatuka i te pa, te hoko ADC, nga korero whakahaere PWM, me te taraiwa i te mata LCD 3.5-inihi hei whakaatu i te ahuatanga o naianei i te waa.Tautokohia te whakarereketanga pa mamao o te rama rama rama rama na roto i te waahanga WiFi, me te tautoko i te whakaoho reo.

Ngā āhuatanga o te hōtaka:

1. Adopt T5L chip to run at high frequency, AD sampling analog is stable, and the error is small;

2. Tautoko TYPE C hono tika ki te PC mo te patuiro me te tahu hōtaka;

3. Tautoko nui-tere OS matua atanga, 16bit tauranga whakarara;UI tauranga PWM matua, tauranga AD arahi atu, hoahoa tono iti-utu, kahore he take ki te tāpiri atu MCU;

4. Tautoko WiFi, mana mamao Nihokikorangi;

5. Tautoko 5 ~ 12V DC ngaohiko whanui me te whakauru whanui

Whakamarama whakataki:

（1）Hoahoa ara iahiko taputapu

1.4 T5L48320C035 hoahoa iahiko

1. MCU arorau mana supply 3.3V: C18, C26, C27, C28, C29, C31, C32, C33;

2. MCU matua supply mana 1.25V: C23, C24;

3. MCU tairitenga mana supply 3.3V: C35 Ko te supply mana tairitenga mo MCU.A, no te momotuhi, ka taea te whakakotahi te papa 1.25V matua me te papa arorau, engari me wehe te papa tairitenga.Ko te whenua tairitenga me te whenua matihiko me kohia ki te pou kino o te putanga LDO punga nui, me kohia ano hoki te pou pai tairitenga ki te pou pai o te LDO puri nui, kia iti ai te haruru AD sampling.

4. Ara iahiko whiwhi tohu tairitenga AD: Ko te CP1 te AD tairitenga taapiri tātari puritanga.Hei whakaiti i te hapa tauira, ka wehe motuhake te papa tairitenga me te papa mamati o te MCU.Ko te pou kino o te CP1 me hono ki te whenua tairitenga o te MCU me te iti o te impedance, a ka hono nga puritanga whakarara e rua o te oscillator karaihe ki te whenua tairitenga o te MCU.

5. Iaiawhio Buzzer: Ko C25 te punga hiko mo te buzzer.Ko te buzzer he taputapu arataki, a, ka puta he naianei teitei i te wa e mahi ana.Hei whakaiti i te tihi, he mea tika ki te whakaheke i te taraiwa MOS o te buzzer ki te mahi i te ngongo MOS i roto i te rohe raina, me te hoahoa i te waahi ki te mahi i roto i te aratau whakawhiti.Kia maumahara me hono whakarara te R18 ki nga pito e rua o te buzzer ki te whakatika i te kounga oro o te buzzer kia pai ai te tangi o te buzzer kia pai, kia pai hoki.

6. WiFi ara iahiko: WiFi maramara sampling ESP32-C, with WiFi+Bluetooth+BLE.I runga i te waea, ka wehea te whenua mana RF me te whenua tohu.

1.5 hoahoa ara iahiko WiFi

I roto i te ahua o runga ake nei, ko te waahanga o runga o te paninga parahi ko te hiko whenua mana.Me whai waahi nui te waahi whakaata antenna WiFi ki te papa hiko, me te waahi kohinga o te papa hiko ko te pou kino o C6.Me whakarato he ohanga whakaata i waenga i te papa hiko me te antenna WiFi, na me whai paninga parahi i raro i te antenna WiFi.Ko te roa o te paninga parahi ka nui ake i te roa o te toronga o te antenna WiFi, a, ko te toronga ka nui ake te aro o te WiFi;tohu ki te pou toraro o C2.Ka taea e te waahi nui o te parahi te whakamarumaru i te haruru i puta mai i te radiation antenna WiFi.Ko nga papa parahi e 2 ka wehea ki te paparanga o raro ka kohia ki te papa waenga o ESP32-C ma roto i te vias.Ko te whenua hiko RF e hiahia ana kia iti ake te impedance atu i te porowhita whenua tohu, no reira e 6 nga vias mai i te papa hiko ki te papa maramara kia pai ai te iti o te impedance.Kaore e taea e te kopae whenua o te oscillator tioata te mana RF e rere ana i roto, ki te kore ka whakaputahia e te oscillator tioata te jitter auau, a ka kore e taea e te taapiri WiFi te tuku me te whiwhi raraunga.

7. Maramarama arataki hiko hiko: SOT23-6LED tauira maramara taraiwa.Ko te tuku hiko DC/DC ki te LED ka hanga takitahi i te kohanga, ka hono te whenua DC/DC ki te whenua 3.3V LOD.I te mea he mea motuhake te tauranga PWM2, ka puta he tohu 600K PWM, ka taapirihia he RC hei whakamahi i te putanga PWM hei mana ON/OFF.

8. Te awhe whakauru ngaohiko: e rua nga hikohiko DC/DC i hangaia.Kia mahara ko nga parenga R13 me R17 i roto i te iahiko DC/DC e kore e taea te waiho.Ko nga maramara DC/DC e rua e tautoko ana ki te whakauru 18V, he pai mo te tuku hiko o waho.

9. USB TYPE C tauranga patuiro: Momo C ka taea te mono me te wete i mua me te whakamuri.Ko te whakauru whakamua ka korero ki te maramara WIFI ESP32-C ki te whakarite i te maramara WIFI;Ko te whakauru whakamuri ka korero ki te XR21V1410IL16 ki te whakarite i te T5L.E tautoko ana a MOMO C i te tuku hiko 5V.

10. Whakawhitiwhiti tauranga whakarara: T5L OS matua he maha nga tauranga IO kore utu, a ka taea te hoahoa tauranga tauranga whakarara 16bit.Ka honoa ki te kawa tauranga whakarara a ST ARM FMC, ka tautokohia te panui me te tuhi tukutahi.

11. LCM RGB hoahoa atanga tere-tere: Ko te putanga T5L RGB e hono tika ana ki te LCM RGB, ka taapirihia te parenga parepare ki waenganui hei whakaiti i te pokanoa ripple wai LCM.I te wa e waeahia ana, whakaitihia te roa o te hononga atanga RGB, ina koa te tohu PCLK, me te whakanui ake i nga tohu whakamatautau RGB PCLK, HS, VS, DE;te tauranga SPI o te mata e hono ana ki nga tauranga P2.4 ~ P2.7 o te T5L, he pai mo te hoahoa i te taraiwa mata.Arataki atu i nga tohu whakamatautau RST, nCS, SDA, SCI kia pai ai te whakawhanaketanga o te raupaparorohiko.
