Kauj Ruam 5: Lwm Cov Lus Qhia rau Lub Tsev Qiv Ntawv

Peb tau npog lub luag haujlwm tseem ceeb ntawm lub tsev qiv ntawv hauv qib dhau los, tab sis ntawm no yog qee yam ntxiv uas kuv xav tias yuav muaj txiaj ntsig kom paub

Siv Tus Txheej Txheem Sab Nraud

Nws yog qhov zoo tshaj plaws los tswj HID lub cuab yeej zoo li no siv lub zog sab nraud xws li lub pob nyem. Yog tias koj siv lub sijhawm thiab qee yam ua tsis raug nws yuav ua rau nws txawv txav mus rau kev sib txuas. Xav txog qhov yuav tsum sim kaw koj lub Bluetooth yog tias koj tau ua yuam kev nws kom nias Ctrl+Alt+Del txhua 100mS!

Hloov lub npe ntaus ntawv

Los ntawm lub neej ntawd lub cuab yeej lub npe yuav tshwm li "ESP32 BLE Keyboard", qhov no tuaj yeem hloov pauv thaum koj tab tom tsim ib qho piv txwv ntawm lub tsev qiv ntawv. Koj tuaj yeem teeb lub npe khoom, chaw tsim khoom thiab qib roj teeb pib.

BleKeyboard bleKeyboard ("Bluetooth Device Name", "Bluetooth Device Manufacturer", 100);

Teeb lub roj teeb theem (tsis ua haujlwm rau kuv tsawg kawg)

Lub tsev qiv ntawv lees tias koj tseem tuaj yeem teeb qib roj teeb tab sis nws tsis ua haujlwm rau kuv ntawm kuv lub Windows PC (nws nyob nrog qhov twg los tus nqi pib yog) thiab kuv lub xov tooj hauv xov tooj tsis qhia tag nrho nws qib. Nov yog cov lus txib rau nws yog tias nws ua haujlwm rau koj

bleKeyboard.setBatteryLevel (50)

Ntaus Compatibility

Kuv tau ua tiav qhov ua piv txwv ntawm kuv Windows 10 PC, xov tooj Android thiab kuv Mac (txawm hais tias nws tseem tab tom khiav Sierra li cas!)

Nws kuj tseem tuaj yeem txuas nrog ib lub cuab yeej ib zaug.

Troubleshooting Kev Pairing

Yog tias koj muaj qee qhov teeb meem ua ke, sim rov pib dua ESP32 thaum koj lub cuab yeej tab tom nrhiav. Kuv kuj ib zaug yuav tsum tau qhib thiab kaw kuv lub bluetooth ntawm kuv lub PC kom nws ua khub.

Kauj Ruam 6: Macro Keypad

Tam sim no peb muaj cov hauv paus tawm ntawm txoj kev, cia ua ib yam dab tsi tawm ntawm nws!

Hauv phau ntawv qhia dhau los kuv tau qhia yuav ua li cas thiaj yooj yim Macro cov keyboard tawm ntawm Arduino pro Micro thiab cov keyboard pheej yig. Rau txhua lub khawm ntawm lub keyboard nws xa sib txawv ua ke ntawm lub pob uas tuaj yeem siv los tswj cov ntawv thov, tus kheej kuv siv nws rau OBS, software kuv siv rau kaw cov vis dis aus thiab rau thaum kuv ntws. Qhov no zoo li yog txoj haujlwm zoo rau kev hla ESP32 yog li peb tuaj yeem ua lub wireless version.

Txog qhov kev tsim no kuv yuav siv Kev Ua Tsis Tau Txaus Siab TinyPICO ESP32 pawg thawj coj. Qhov laj thawj tseem ceeb rau kev xaiv nws yog pawg tswj hwm lub zog muaj txiaj ntsig zoo thiab muaj lub hauv paus rau kev khiav tawm thiab them lub roj teeb Lipo ua hauv, yog li txhua yam kuv yuav tsum tau ua yog ntsaws lub roj teeb rau hauv.

Kuv yuav dag yog tias qhov tseeb tias nws muaj kab sib nrug ib yam li Pro Micro thiab kuv tuaj yeem siv qhov uas tau ua dhau los ua pawg thawj coj uas kuv tau ua yav tas los tsis zoo txaus!

Cov keyboard yuav tsum tau 8 tus pin GPIO los ua haujlwm, thiab TinyPICO muaj 8 GPIO tus pin ua ke yog li peb yuav siv lawv. Koj tuaj yeem yooj yim txuas cov keyboard rau TinyPICO raws li qhia hauv daim duab saum toj no.

Kauj Ruam 7: Txoj Cai rau Macro Keypad

Cov cai rau Macro Keypad kos duab tuaj yeem pom ntawm kuv Github.

Ib yam li BleKeyboard lub tsev qiv ntawv uas tau teeb tsa hauv ib kauj ruam dhau los, koj tseem yuav xav tau teeb tsa lub tsev qiv ntawv rau cov keyboard, koj tuaj yeem ua qhov no los ntawm kev qhib lub chaw saib xyuas lub tsev qiv ntawv los ntawm kev mus rau Sketch -> Xws li Lub Tsev Qiv Ntawv -> Tswj Tsev Qhua

Sab hauv tus thawj tswj tsev qiv ntawv, tshawb rau "keypad" thiab teeb ib qho los ntawm Mark Stanley thiab Alexander Brevig

Ib qho kev teeb tsa uas koj yuav xav tau yog tias koj siv ESP32 sib txawv dua li TinyPICO yog tus lej khawm, lawv tau teeb tsa hauv rowPins thiab colPins array. Thaum saib ntawm lub hauv ntej ntawm cov keyboard thiab pib los ntawm sab laug, thawj 4 tus pin yog kab pins thiab thib ob 4 yog cov pins.

Thaum qhov no ua tiav, xa cov cai mus rau lub rooj tsavxwm thiab koj yuav tsum sim ntawm theem no nws ua haujlwm.

Kauj Ruam 8: Cia Peb Ua Nws Wireless

Raws li tau hais ua ntej, TinyPICO muaj kev sib txuas rau kev tuav lub Lipo ua hauv yog li txhua yam peb yuav tsum tau ua yog txuas nws. Nws los nrog JST cov khoom sib txuas uas tuaj yeem muab txuas rau hauv qab, lossis koj tuaj yeem siv Bat thiab GND pins yog tias koj xav ua nws ntawm tus pin.

Yog tias koj tab tom siv JST cov khoom sib txuas thov txheeb xyuas ob qho tib si ntawm koj lub roj teeb sib xws nrog TinyPICO, tsis muaj tus txheej txheem yuav ua li cas cov no yuav tsum tau siv kab yog li muaj lub sijhawm zoo koj lub roj teeb yuav tsis sib xws.

Txheeb xyuas qhov hluav taws xob ntawm koj lipo roj teeb ua ntej siv nws, lub roj teeb noj qab nyob zoo yuav tsum yog 3V lossis siab dua, lub roj teeb kuv pom nrog qhov raug JST txuas tau nyeem 0V!

Kuv tau siv lub xov tooj 18650 hauv tus tuav thiab muab nws txuas rau JST txuas ntawm lub roj teeb tuag.

TinyPICO txo nws lub zog siv thaum khiav lub roj teeb los ntawm tsis ua lub zog ntawm ib qho ntawm nws cov LEDs, yog li txawm tias nws tsis saib, vam tias nws yog! Kev txhim kho yav tom ntej ntawm txoj haujlwm yuav yog txhawm rau rub lub onboard dotstar LED ntawm kev pib tsuas yog qhia rau koj paub tias nws tau qhib tiag tiag thiab tej zaum ntxiv thaum nws txuas. Txog tam sim no koj tuaj yeem tshawb xyuas hauv koj lub tshuab Bluetooth cov ntawv qhia zaub mov uas nws tau qhib thiab txuas tau zoo.

Kauj Ruam 9: Xeem Nws

Cia peb sim nws, yog tias kuv qhib qhov hotkeys feem ntawm OBS Kuv tuaj yeem nyem rau ntawm qhov sib txawv los sau cov khawm ua ke uas yuav tswj nws, rau qhov no peb tuaj yeem nyem rau ntawm lub pob ntawm peb lub keyboard thiab nws yuav hloov tshiab.

Tom qab koj nyem thov, koj yuav tsum tsis tuaj yeem siv koj lub keyboard los tswj koj qhov xwm txheej hauv OBS.

Kauj Ruam 10: Ua Tsaug Rau Kev Nyeem

Vam tias koj pom Cov Lus Qhia no muaj txiaj ntsig. Kuv yuav nyiam hnov txog qhov koj yuav ua nrog hom teeb tsa no. Thov qhia rau kuv paub hauv cov lus hauv qab no, lossis koom nrog kuv thiab ib pawg ntawm lwm tus tsim ntawm kuv li Discord server, qhov uas peb tuaj yeem tham txog cov ncauj lus no lossis lwm tus tsim muaj feem cuam tshuam nrog koj muaj, tib neeg yeej muaj txiaj ntsig zoo yog li nws yog qhov chaw zoo rau dai tawm

Kuv kuj tseem xav ua tsaug ntau rau kuv Github Sponsors uas pab txhawb qhov kuv ua, Kuv yeej txaus siab rau nws. Yog tias koj tsis paub, Github sib piv cov kev txhawb nqa rau thawj xyoo, yog li yog koj ua tus txhawb nqa lawv yuav phim nws 100% rau ob peb hlis tom ntej.
