2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Tsim nyob rau xyoo 1978 los ntawm Fab Kis Kev Sib Tham, Minitel yog cov ntaub ntawv khaws cia thiab xa ntawv. Pom tau tias yog lub network muaj kev vam meej tshaj plaws ua ntej lub ntiaj teb dav web. 30 xyoo nyob rau xyoo 2008 lub network thaum kawg tau kaw. (Muaj ntau cov ntaub ntawv hais txog qhov no ntawm Wiki.) Hmo ntuj cov chaw no tau dhau mus lawm.

Suav nrog CRT lub vijtsam keyboard, modem thiab qee qhov kev hloov npe, cov "ruam" no tsis muaj peev xwm ua cov ntaub ntawv. Yog li koj tuaj yeem ua dab tsi nrog nws? Hloov nws mus rau hauv lub moos!

Kauj Ruam 1: Daim Ntawv Teev Npe Componants

Atmega 328p microprocessor nrog Arduino bootloader

16 mhz siv lead ua

22 pf capacitor x 2

10 kOhm resistor

100 uf electrolytic cap

DS3231 RTC tus qauv

header pins kom yooj yim txuas

(10kOhm & 100kOhm resistors: yeem)

qee cov xov hlau thiab cov laug

Arduino Uno pawg thawj coj saib rau kev rub tawm daim duab

Thiab, tau kawg, Minitel 1 lub davhlau ya nyob twg

Kauj ruam 2: Schematic

Schematic yog yooj yim heev. Nws yog koj qhov yooj yim Atmega328p teeb tsa nrog RTC txuas nrog analog pins 4 & 5. Minitel rx thiab tx txuas nrog digital pins 7 & 8. Qhov ntawd yog qhov pib. Hauv ib qho ntawm kuv qhov piv txwv kuv tau ntxiv ob peb tus resistors los tsim qhov faib hluav taws xob uas txuas nrog tus pin analog 3. Tam sim no minitel tuaj yeem yog DC voltmeter txog 50 volts. Koj kuj tseem tuaj yeem ntxiv lwm yam khoom siv ntxiv, xws li LDR, ntsuas cua sov, lub microphone thiab lwm yam. Cov txheej txheem uas kuv tau kos tsis muaj qhov faib hluav taws xob faib tawm qhov hluav taws xob pom. Koj tuaj yeem xav ntxiv lwm yam, qhov sib txawv lossis tso nws tawm tag nrho.

Kauj Ruam 3: Txuas Txuas

NCO NTSOOV: Ua ntej tshem lub Minitels casing, xyuas kom koj tau txiav nws los ntawm lub hwj huam hluav taws xob thiab tso cai 5 feeb rau lub tshuab hluav taws xob siab kom tau tso dej.

Muaj ntau chav nyob hauv Minitel rau koj lub Circuit Court, tab sis nco ntsoov tias nws tsis kov lwm qhov. Kuv tau ntsia kuv tus kheej rau lub vaj huam sib luag tshem tau.

Txuas RX thiab TX ntawm koj lub xov tooj mus rau TX thiab RX ntawm Minitel. saib duab thiab schematic. Yog tias koj txuas cov no tsis raug, nws tsis muaj biggie, koj tuaj yeem yooj yim pauv tus lej tus lej hauv koj tus lej. (ntau ntxiv txog qhov ntawd tom qab)

Nrhiav tus Minitels 7805 tus tswj hluav taws xob thiab txuas koj lub Circuit Court rau nws. (Nco ntsoov tias koj tau txais koj qhov kev hloov pauv kom raug. Ib txwm! Ib txwm! Ib txwm !! xyuas ob zaug ua ntej hloov nws.)

Nyob tom qab ntawm Minitel muaj lub qub Fabkis Telecom xov tooj ntsaws thiab qhov (socket). Tshem tawm thiab tshem tawm lub ntsaws thiab cov hlau lead. Tom ntej no, txuas lub qhov hluav taws xob txuas rau koj lub Circuit Court. Koj yuav tuaj yeem hloov kho thiab xa cov duab tshiab rau koj hauv Circuit los ntawm kev yooj yim txuas koj Arduino Uno board rau lub qhov rooj yam tsis tas yuav qhib thiab tshem koj lub microcontroller. Tsis tas li, koj tuaj yeem txuas koj tus lej pin sib piv rau ib qho ntawm lub davhlau ya nyob twg ntxiv rau lwm yam khoom siv, raws li tau hais hauv kauj ruam dhau los.

Kauj ruam 4: Mus thiab Khiav

Nov yog qee cov duab.

Kauj ruam 5: Txoj Cai

Txoj cai siv peb lub tsev qiv ntawv. SoftwareSerial, Minitel thiab DS3231. Txhua yam tuaj yeem rub tawm los ntawm GitHub. Kev hu xov tooj Minitel m (7, 8) teeb tsa Minitels RX & TX ntawm tus pin digital 7 & 8. (Cov no tuaj yeem hloov pauv mus rau lwm tus pin uas koj xav tau)

Tom qab ntawd muaj tag nrho cov lej thiab cov cim cim rau tus lej loj thiab qhov chaw nkag mus. teeb () pib lub sijhawm tiag tiag. (koj tuaj yeem teem sijhawm thiab hnub tim ntawm no yog tias koj xav tau.

Raws li Minitel 1 qeeb thiab muaj lub peev xwm siv duab tsawg heev, (hnub nyoog 40 xyoos) nws yog qhov tseem ceeb kom ua kom koj lub luag haujlwm luv li sai tau. Lub Loop tseem ceeb cuam tshuam nrog kev nyeem cov ntawv tseem ceeb thiab xaiv hom. Hauv cov ntawv qhia zaub mov thiab teeb tsa cov txheej txheem, tsis muaj kev nyeem RTC thiab rov ua dua tshiab ntawm cov duab yog li cov tswv yim los ntawm cov keyboard tau nyeem sai. Txawm li cas los; nyob rau hauv lub moos hom qhov tseem ceeb nias tuaj yeem siv sijhawm ob peb zaug los ua haujlwm. Ua siab ntev.

Cov piv txwv tus lej no yog rau lub tswb moos thiab tsis yog lub ntsuas hluav taws xob. Yog tias koj xav tau cov cai rau lub ntsuas hluav taws xob kuv yuav xa raws qhov kev thov.

Kuv yuav tsis tham tag nrho los ntawm txoj cai. Tej zaum koj tau hla ntu no lawm.

Kuv tus lej yog ntxhib thiab ntxaws. Kuv yeej xav tau ntxuav nws. tab sis nws ua haujlwm. Thaum kuv muaj sijhawm kuv nrog kho nws thiab tshem tawm cov tsis siv cov lej thiab cov khoom.

Ua tsaug rau koj saib. Kuv vam tias koj txoj haujlwm Minitel moos zoo.
