Kauj Ruam 2: Tsim Cov Duab Dub thiab Dawb

Koj tuaj yeem tsim cov duab kom pom los ntawm kev siv vector duab (piv txwv li InkScape) lossis pixel duab (piv txwv li GIMP) cov haujlwm, tab sis qhov tso tawm zaum kawg yuav tsum yog 296 x 128 pixel dub thiab dawb bmp-file.

Yog li, rau cov duab xim kom pom ntawm daim ntawv e-ntawv nws yuav tsum hloov pauv mus ua cov duab dub thiab dawb.

Koj tuaj yeem siv cov duab bmp los ntawm kev sau (cov kauj ruam kawg), lossis koj tsim qee yam ntawm koj tus kheej. raws li tau piav qhia hauv qab no. Tej zaum yuav muaj ntau txoj hauv kev kom mus txog lub hom phiaj, tab sis kuv tau siv cov txheej txheem yooj yim heev thiab ncaj qha siv GIMP:

1. Tsuas yog tau txais daim duab-ntawv nrog lub qhov ncauj ua ntu me me tsawg kawg 296 pixel dav 128 pixel siab. Qhov no yuav xav tau lub ntsej muag zoo nkauj pem hauv ntej.
2. Xaiv ib cheeb tsam uas muaj qhov dav rau qhov siab sib piv li ntawm 2.32 rau 1 thiab siv Duab - Txo kom xaiv*
3. Tom qab ntawd, siv Duab - Nplai duab* kom nqes mus rau 296 pixel dav (lossis 128 pixel siab).
4. Raws li txuas ntxiv, xaiv thaj tsam 296 x 128 pixel loj thiab txiav cov duab kom xaiv raws li saum toj no.
5. Raws li qhov loj me yuav tsum yog 296x128 pixel, siv Duab-Kho Canvas Loj* los kho yog tias xav tau
6. Tam sim no hloov cov duab rau grayscale siv Duab - Hom - Grayscale. Cov kauj ruam no tsis yog qhov tsim nyog nruj me ntsis, tab sis tuaj yeem muaj txiaj ntsig zoo rau kev hloov kho thiab ua kom zoo dua (saib qib 9).
7. Tom qab ntawd hloov mus rau hauv b & w bitmap siv Duab - Hom - Indexed* nrog kev xaiv "1 ntsis" thiab "Floyd -Steinberg" dithering
8. Thaum kawg, xa cov bitmap li BMP rau daim nplaub tshev tsim nyog
9. Koj tuaj yeem sim ua kom zoo dua qhov txiaj ntsig los ntawm kev hloov kho qhov tsis sib xws lossis qhov ci ntawm cov duab grey-scale. Xim- Cheeb Tsam- Tshem tawm cov khoom-RGB ntsuab channel yog qhov kev xaiv yooj yim txhawm rau txhim kho cov duab thiab txhim kho cov xim liab raws li lub qhov ncauj. Rov qab mus rau kauj ruam 7.
10. Txog qhov "ua yeeb yaj kiab GIF" zoo li cov yeeb yaj kiab, koj tuaj yeem npaj tus lej sib law liag raws li saum toj no thiab lub npe thiab tus lej BMPs raws li qhov tseeb. Tom qab ntawd koj tuaj yeem tso lawv ib qho tom qab ib qho ntawm cov zaub.
11. Muab cov ntaub ntawv tso rau hauv daim duab-subfolder tawm ntawm e-ntawv piv txwv nplaub tshev, yog tias xav tau hloov npe lawv (piv txwv li image_1.bmp, …)
12. Hloov cov npe bmp-cov ntaub ntawv muab hauv cov piv txwv tsab ntawv nrog cov uas ntawm koj cov ntaub ntawv.

Lus Cim:

• Kuv tsis paub tseeb tias kuv tau txais cov npe lus Askiv ntawm txhua qhov GIMP cov lus hais kom raug, zoo li kuv tab tom siv lus German.
• Rau qee qhov piv txwv cov duab xaiv cov duab coj los ntawm internet tau siv, yog li cov no yuav tsis siv hauv kev tshaj tawm lossis rau lub hom phiaj kev lag luam.

Kauj Ruam 3: Cov Khoom Siv Hluav Taws Xob thiab Kev Sib Ntsib

Kev sib dhos ntawm cov khoom siv hluav taws xob yog qhov yooj yim. Lub khawm shim, yog siv ncaj qha txuas rau RPi, yuav tsum tau muab muag rau RPi's GPIO raws li qhia hauv cov khw muag khoom qhia. Raws li qhov shim yog nyias heev, HAT tuaj yeem tso rau ntawm GPIO nrog shim txuas. Siv cov tshuaj txhuam me me li sai tau thiab sim tsis txhob kis kab mob GPIO pins saum toj ntawm thaj chaw shim, desolder yog xav tau. Ua ke nrog WaveShare e-Paper HAT koj kuj tseem tuaj yeem ntxiv Pimoroni ZeroLiPo shim rau GPIO ntxiv rau khawm shim, uas tuaj yeem tso cai siv LiPo me me ua lub zog siv. Tom qab ntawd muab e-Paper HAT rau GPIO siv qhov sawv ntsug tawm nrog HAT.

Txuas cov ntawv e-ntawv thiab txuas kab txuas ncaj qha rau e-paper adapter thiab tom qab ntawd mus rau e-paper HAT raws li tau piav qhia los ntawm cov chaw tsim khoom (cov neeg tsim xiav tom kawg ntawm FFC cable sab-sab). Teeb ob lub hloov pauv ntawm HAT raws li qhov xav tau ntawm cov zaub siv, rau qhov hloov pauv tau 2.9 '' zaub rau "A" thiab "0".

Nco ntsoov tias koj tau teeb tsa txhua qhov xav tau software thiab tsev qiv ntawv teeb tsa.

Koj yuav xub xub siv cov ntawv sau piv txwv muab los ntawm Pimoroni thiab WaveShare los tshuaj xyuas kev ua haujlwm ntawm cov khoom, tom qab ntawv sim cov phiaj xwm tshwj xeeb (qhia hauv cov kauj ruam tom ntej).

Muab qhov nyuaj- thiab software ua haujlwm, tam sim no koj tuaj yeem txuas cov zaub thiab e-Paper adapter rau lub hnab ntawv lossis lub npog ntsej muag. Kuv yuav hais kom kho cov zaub thiab hloov pauv ntawm qee qhov hloov pauv tab sis txaus txhav thim rov qab, Kuv siv daim ntawv yas nyias thiab daim kab xev ob sab. Tam sim no daim ntawv thim rov qab tuaj yeem siv los kho cov zaub rau koj daim npog ntsej muag lossis rau lub hnab ntawv tiv thaiv loj dua, piv txwv. los ntawm kev xaws lossis siv ob daim kab xev, daim ntawv tso cai los yog cov hlau nplaum me.

Raws li FFC cable txuas RPI thiab zaub tsuas yog 20 cm ntev, Kuv tau siv hlua hlua hlua qhwv ncig HAT sawv ntsug-ua kom Raspberry Pi hnav tau ze rau ntawm lub ntsej muag. Raws li tau tham, ntev cable lossis txuas txuas cable yuav yooj yim dua.

Txog qhov qauv kuv tau siv lub hnab yas zoo li lub hnab yas (20x9.5 cm), qhov tseeb yog qee cov khoom ntim uas tau nyob ntawm tes. Tom qab ntawd kuv txiav lub qhov rau cov zaub thiab kho cov zaub / thaub qab phaj nyob ntawd. Tom qab ntawd kuv txuas plaub daim yas yas ntawm lub ces kaum, saib cov duab. Txhawm rau tuav tag nrho txhua qhov chaw ntawm lub ntsej muag Kuv tau siv ob txoj hlua roj hmab txhais nrog cov nuv los ntawm cov khoom siv khiab mis kho. Yog li lawv mus nyob ib puag ncig koj lub taub hau thiab kho qhov ntev yog yooj yim heev.

Kauj ruam 4: Tsab Ntawv

Cov piv txwv tsab ntawv yog kev sib koom ua ke ntawm cov ntawv sau qhia los ntawm WaveShare rau cov zaub HAT (saib Github ntawm no) thiab los ntawm Pimoroni rau khawm Shim (saib ntawm no). Ib qho kev qhuas mus rau lawv, Kuv yuav ua qhov txhaum. Txhua cov lus hais thiab cov lus pom zoo rau kev ua kom zoo siab txais tos.

Tsab ntawv WaveShare xav tau ntau lub tsev qiv ntawv los teeb tsa, raws li qhia hauv cov ntaub ntawv ntawm GitHub. Yog li Pimoroni tsab ntawv, tab sis ntawm no muaj cov cuab yeej los ua txoj haujlwm rau koj.

Qhov zoo tshaj plaws siv daim npav SD tshiab tshiab nrog Raspian, tom qab ntawd ntxiv Pimoroni cov cuab yeej siv

sudo apt-tau nruab pimoroni

thiab siv nws los teeb tsa khawm shim cov lej (pom hauv qab "lwm tus") thiab kev vam khom.

Rau WaveShare ib feem, theej lawv cov tsav tsheb thiab cov piv txwv pob los ntawm GitHub nplooj ntawv thiab teeb tsa nws thiab ib qho kev vam khom raws li tau piav qhia muaj (!). Feem ntau kev vam khom yuav tau ua tiav.

Muab cov ntawv sau rau hauv cov nab npawb piv txwv ntawm WaveShare tso saib software thiab luam cov bmp-cov ntaub ntawv rau hauv pic subfolder.

Siv tsab ntawv yog qhov yooj yim. Hauv qhov xwm txheej, hloov cov npe ntawm bmp-cov ntaub ntawv hauv BMPs cov npe rau cov uas koj xav pom. Koj tuaj yeem npaj cov npe khaws tseg thiab tsuas yog hloov qhov uas xav tau hauv cov npe nquag los ntawm kev luam hauv.

Khiav tsab ntawv. Txheeb xyuas yog tias txhua yam ua haujlwm tau zoo. Tom qab ntawd koj tuaj yeem tshem tawm HDMI thiab USB hloov pauv (nrog qee lub USB-hubs, tshem tawm yuav txwv tsis pub RPi) thiab tso daim npog ntsej muag ntawm koj lub ntsej muag thiab hlua hlua nyob ib puag ncig koj lub caj dab. Saib hauv daim iav thiab ua si los xyuas seb txhua yam ua haujlwm tau zoo.

Cov ntawv tau raug txaij mus rau qhov tsawg kawg uas yuav tsum tau nyeem cov nyees khawm thiab tso saib bmps. Yog li yog tias koj xav pom cov ntawv, kab lossis cov duab geometric, thov ntxiv cov ntsiab lus xav tau los ntawm 2in9d piv txwv tsab ntawv.

Cov duab, uas yuav tsum tau nyob hauv "pic" nplaub tshev, tau teev nyob rau hauv cov npe "BMPs", uas suav nrog 5 daim ntawv teev npe nrog lub npe ntawm 5 daim duab txhua, lossis 25 daim duab tag nrho. Thawj daim duab hauv txhua daim ntawv teev npe txuas nrog khawm A, qhov thib ob rau khawm B, thiab ntxiv rau. Cov npe tuaj yeem xaiv los ntawm kev nias ntev ntawm cov nyees khawm A txog E, piv txwv li vaj huam sib luag 1 raug xaiv siv khawm A, vaj huam sib luag 2 los ntawm khawm B thiab lwm yam. tsis ntev los yog tuav ntev dua 2 vib nas this, ua rau muaj kev hloov pauv ntawm tus chij hloov pauv. Lub voj ntawm txoj haujlwm tseem ceeb tsuas yog kuaj pom yog tias lub pob raug nias/tuav nyeem cov chij button_was_held thiab button_was_pressed, thiab cov chij twg (panel_flag, button_flag) tau raug tsa. Tom qab ntawd nws teeb tsa qhov sib txawv sib txawv (vaj huam sib luag lossis duab) raws li. Thaum kawg cov duab sib xws rau “BMPs [vaj huam sib luag] [duab]” raug xaiv los ntawm cov npe thiab sau rau cov zaub. Tom qab ntawd chij tau rov pib dua rau lawv cov av hauv av "tsis muaj" lossis "Tsis tseeb".

Tus so ntawm tsab ntawv feem ntau yog hais txog teeb tsa kev hloov pauv, pib ntawm cov zaub thiab qee qhov ua yuam kev. Koj tuaj yeem khiav tsab ntawv los ntawm IDE, lossis los ntawm lub console siv "python3 Button_shim_2in9_1.py". Xwb, koj yuav muaj tsab ntawv khiav ncaj qha tom qab khau raj.

Tsab ntawv tseem tab tom txhim kho qhov zoo, yog li thov txheeb xyuas qhov hloov tshiab.

Qhov hloov tshiab kawg (2020-Tsib Hlis -10) muaj lub luag haujlwm los tso saib cov duab hauv cov npe BMPs, display_gallery (), thiab ib qho los tso saib cov ntawd hauv cov npe sau _x, display_collections (). Tsis suav nrog hauv cov npe hauv qab no, saib cov ntawv txuas nrog.

Thov nco ntsoov tias, kom zam "dab", lwv ib daim duab yog tias cov duab tsis siv rau ob peb hnub.

Ib zaug ntxiv: qee cov duab lossis cov cim (piv txwv li Raspberry, Apple, Instructables) tej zaum yuav raug txwv txoj cai thiab yuav tsum tsis siv rau kev lag luam.

Kauj Ruam 9: Lwm Txoj Hauv Kev: Adafruit Feather thiab E-paper Display

Kuv paub hnub no (21-Tsib Hlis-2020) tias Adafruit tseem muab cov ntawv e-ntawv hloov pauv tau ntawm qhov loj me thiab qhov ntev (https://www.adafruit.com/product/4262, 27 US $) ntxiv rau 25 cm 24 tus pin 0.5mm suab txuas txuas txuas txuas (https://www.adafruit.com/product/4230, 1.5 US $) thiab txuas txuas (https://www.adafruit.com/product/4524).

Lawv muaj tus tsav tsheb e-ntawv rau lawv tsev neeg Feather board (Adafruit eInk Feather Friend nrog 32KB SRAM, https://www.adafruit.com/product/4446, 9 US $) uas los nrog daim npav SD tuav kom tuav tag nrho cov no duab

Kuv xav tias qhov no yuav tso cai rau teeb tsa ntau dua thiab siv hluav taws xob ntau dua li Raspberry Zero version tau piav qhia hauv no, thiab yuav yog kev daws teeb meem zoo tshaj yog tias koj xav siv STM32F405, 32u4 lossis nRF52840 platform. Hmoov tsis zoo, nws zoo li tsis tseem ceeb los ua ke Adafruit's eInk Feather Friends thiab WaveShare qhia.

Kuv yeej nyiam pom ib qho version nrog BLE thiab app los tswj cov duab uas tau tshwm.

WaveShare tab tom muab Arduino tso saib daim thaiv tsav tsheb thiab ESP3266 raws cov tsav tsheb, yog tias koj nyiam cov no.
