2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Kuv tau mus ntawm kev yoog raws kuv qhov Ripple LoRa mesh uas twb muaj lawm los nrog cov cuab yeej xa xov ib leeg uas tsis xav tau cov cuab yeej siv Android ua ke.

Cov cuab yeej no tuaj yeem siv nrog rau lwm cov khoom siv xa xov ib leeg, lossis nrog Ripple mesh cov cuab yeej uas siv Ripple Messenger app. Lawv tuaj yeem sib koom tes tau, thiab lawv tau tsim lawv tus kheej lub network sib txuas, nrog qhov kawg-rau-kawg ECC encryption. Thiab, tau kawg, lawv txhua tus tuaj yeem siv cov xov tooj cua rov ua dua tshiab kom zoo dua qub/ntseeg tau.

Khoom siv

• TTGO LoRa32 V2.1
• DS3231 RTC tus qauv
• Keyboard module
• Piezo buzzer
• 1S Lipo roj teeb

Kauj ruam 1: Pib

Koj yuav xav tau daim npav micro SD nco, uas yuav tuav koj tus ID, teeb tsa, kev sib cuag thiab kev sib tham khaws tseg. Koj yuav tsum npaj daim npav SD nrog cov ntawv teeb tsa, uas koj ib txwm tsuas yog xav tau ua ib zaug xwb.

Hauv cov neeg koj xav tsim lub network nrog, koj yuav tsum tau muab thiab muab tus lej tshwj xeeb rau txhua tus neeg, hauv thaj tsam ntawm 1 txog 254. Tsis muaj lub hauv paus server, tsis muaj internet, yog li qhov no yog koj li kev faib tawm. Hauv computer, ntxig daim npav SD, thiab tsim daim nplaub tshev hu ua 'ripple'. Hauv cov npe ntawd, tsim cov ntawv sau yooj yim hu ua 'conf.txt' (Unix format, Not MS-DOS!) Cov ntawv no yuav tsum zoo li zoo li saum toj no

Cov kab tuaj yeem yog nyob rau hauv ib qho kev txiav txim, tab sis thawj 2 tus cim yog lub npe khoom (piv txwv li. 'ID' yog koj tus lej) ua raws tus nqi, xaus nrog kab ntawv tshiab. Qhov khoom yog:

• GR - Pawg ID (tuaj yeem tawm mus li 0)
• ID - Koj tus ID tshwj xeeb (1..254)
• FQ - LoRa zaus siv
• SF - LoRa kis tau zoo los siv (10..12)
• NM - Koj lub npe tso tawm (lwm tus pom qhov no)
• TZ - Koj lub sijhawm nyob hauv feeb ua ntej ntawm GMT. (yeem)

NCO TSEG: txhua tus hauv koj pab pawg yuav tsum siv tib GR, SF, thiab FQ qhov tseem ceeb !! Thaum koj tau teeb tsa koj daim npav SD, tsuas yog ntxig rau hauv qhov sab xis, thiab txhawb nqa lub cuab yeej. 4-txoj kev qhia cov yuam sij tau siv rau kev taw qhia. Nce/nqis los xaiv kev sib cuag, Txoj cai xaiv. (Sab laug lossis ESC tau siv rov qab mus rau lub vijtsam dhau los).

NCO TSEG: Blackberry keyboard

Rau cov keyboard no kuv tau xaiv rau qhov tseem ceeb ua ke rau 4-txoj kev kev qhia:

• Up: ALT + P (tus '@' char)
• Down: ALT + ENTER
• Rov qab: ALT + $
• Xaiv: ENTER

Kauj Ruam 2: Hloov Cov Yuam Nrog Lwm Tus

Txhawm rau ntxiv lwm tus neeg siv, piv txwv li. kev sib cuag, koj yuav tsum nkag mus rau chav tshwj xeeb '-Exchange-' chav. Rau chav sib tham no, koj yuav tsum pom zoo tus lej 4-tus lej nkag nrog lwm tus, ntaus nws hauv, tom qab ntawd nyem ENTER.

Ntawm no koj xaiv cov khoom saum toj kawg nkaus '-Kuv Paub-' thiab nias ENTER tshaj tawm koj tus lej ID, npe, thiab tus yuam sij rau pej xeem encryption rau txhua tus neeg hauv chav. Thaum lwm tus ua qhov no, koj yuav pom lawv tus ID, lub npe tshwm hauv daim ntawv. Siv Up/Down yuam sij los xaiv, tom qab ntawd Txoj Cai lossis ENTER qhov tseem ceeb txhawm rau ntxiv tus neeg siv rau koj cov neeg sib cuag (khaws cia rau hauv koj daim npav SD).

Koj tuaj yeem ua qhov no txhua lub sijhawm, ntxiv lossis hloov kho cov neeg siv rau hauv koj daim ntawv teev npe.

Kauj ruam 3: Kev sib tham

Los ntawm lub vijtsam tseem ceeb, siv Up/Down cov yuam sij los xaiv kev sib cuag, tom qab ntawd Txoj cai nkag mus rau qhov kev sib tham.

Tsuas yog siv cov keyboard los ntaus cov lus koj xav xa, tom qab ntawd nyem ENTER. Cov ntawv yuav nyem rau/tawm thaum xa ntawv tseem tab tom ua. Yog tias ua tiav, cov lus xa mus rau hauv kev sib tham, txwv tsis pub yog nws ua tsis tau tiav xa nws yuav tsum nres flashing thiab nyob qis dua kab rov tav.

Kauj ruam 4: Ceeb toom

Lub vijtsam txiav tawm tom qab 15 vib nas this yog tias tsis muaj tus yuam sij raug nias. Yog tias cov lus tshiab tuaj txog, lub vijtsam tig rau pom qhov puv npo saib ua ntej ntawm cov lus thiab lub npe xa, nrog lub teeb ntsuab LED ntsais, thiab lub suab nrov nrov.

Los ntawm no, koj tuaj yeem nias sab laug lossis ESC tus yuam sij kom rov qab mus rau lub vijtsam hauv tsev, lossis Txoj Cai lossis ENTER qhov tseem ceeb nkag mus rau lub vijtsam sib tham.

Kauj Ruam 5: Kev thaiv kab

Saum toj no yog kab duab kab rau koj siv. Nws yog qhov yooj yim haum, tsuas yog koom nrog ob I2C qhev tus qauv (RTC moos, thiab cov keyboard), thiab piezo buzzer.

Kauj ruam 6: Flashing Firmware

Lub firmware yog nyob ntawm Ripple github nplooj ntawv:

NCO TSEG: tshem daim npav micro SD ua ntej sim ua kom flash firmware! Vim li cas qhov no cuam tshuam nrog USB ntu. Muaj cov lus qhia ntawm lub xaib yuav ua li cas nyem lub firmware rau ntawm TTGO ESP32 lub rooj tsavxwm.

Kauj Ruam 7: Luam Ntawv Case & Assembly

Thov saib qhov Txuas Txuas Txuas no rau cov ntaub ntawv STL. Muaj ob daim tseem ceeb, lub plhaub sab saud thiab qis. Kuj tseem muaj ob daim me me los ua kev cai rau/tawm hloov slider.

Koj yuav xav tau tus lej M2 txhawm rau txhawm rau txhawm rau TTGO lub rooj tsavxwm thiab cov keyboard rau sab saum toj ntawm daim plhaub.

Ruaj ntseg cov keyboard mus rau sab saum toj ntawm rooj plaub nrog 2x M2 ntsia liaj qhov rooj, thiab xov cov hlua kab hla los ntawm lub qhov, khoov nws rov qab thiab nyem rau hauv pawg tswj hwm uas tau ruaj ntseg rau hauv qab (saib daim duab saum toj no).

Tom qab ntawd, sib sau ua ke qhov qhib/tawm los ntawm lub qhov, tom qab ntawd kaw ob lub plhaub ua ke.

Kauj Ruam 8: Teeb RTC Moos

Txhawm rau cog RTC tus qauv, koj yuav tsum tsim cov ntawv tshwj xeeb ntawm SD daim npav nrog koj lub khoos phis tawj. Hauv 'ripple' nplaub tshev, tsim cov ntawv sau yooj yim hu ua 'clock.txt' (Unix hom ntawv, Tsis yog MS-DOS). Kho cov ntaub ntawv thiab ntxiv cov hnub hauv qab no qhov tseem ceeb ntawm cov kab sib cais, hauv qhov kev txiav txim no:

xyoo

hli (1..12)

hnub ntawm lub hlis (1..31)

teev (0..23).

feeb (0..59)

vib nas this (0..59)

Txuag cov ntawv, tshem tawm daim npav SD, tom qab ntawv xaub nws mus rau hauv lub cuab yeej. Koj yuav tsum tau rov pib dua lub cuab yeej rau nws kom siv tau. Tam sim no RTC lub moos yuav tsum tau teeb tsa, thiab lub vijtsam hauv tsev yuav tsum qhia lub sijhawm raug.

Kauj Ruam 9: Xaus

Yog tias koj pom qhov haujlwm no muaj txiaj ntsig thiab zoo li ntuav qee qhov Bitcoin kuv txoj hauv kev, Kuv yuav zoo siab heev:

Tswv yim

Thaum SHTF tshwm sim, lossis zombie apocalypse tsoo, lossis lub hnub qub, lossis xijpeem, thiab koj yuav tsum tham nrog koj tsev neeg thiab cov phooj ywg, Kuv vam tias cov khoom siv no yooj yim!:-) Tsis txhob tso cov lus tawm thiab nug kuv cov lus nug uas koj muaj.
