Hloov Kho Lub Yim Hli 2018-Saib Cov Lus Qhia Tshiab:

Hloov kho 28 Lub Plaub Hlis 2016: Tam sim no 16 qhov kev tawm / cov ntsiab lus tswj lub peev xwm rau Chaw Nres Nkoj. Kev tawm mus T1 - T8 muaj nyob ntawm 'B' qhov tseem ceeb qhov kev tawm mus T9 - T16 muaj nyob ntawm 'C' qhov tseem ceeb

Hloov kho lub Peb Hlis 10, 2016:

Tam sim no ntxiv 8 qhov kev tawm mus / cov ntsiab lus tswj lub peev xwm rau Chaw Nres Nkoj. Tus lej Arduino tau hloov kho raws li siv NMRA tus qauv txheej txheem rau kev tawm mus (tseem raws li kev tshawb fawb ntawm Lenz / Atlas Compact cov ntaub ntawv pob rau kev tswj hwm kev tawm mus).

Kev tawm mus T1 - T8 muaj nyob ntawm 'B' qhov tseem ceeb

Saib cov lus qhia ntawm cov ntaub ntawv pob ntawv tau txais Circuit siv thiab Arduino code xav tau.

Hloov kho 18 Lub Ib Hlis 2016:

Kuv tau ntxiv qhov kev nkag siab tam sim no resistor (1k5 ohm) thiab capacitor (10 uf) rau hauv Circuit Court thiab hloov kho Arduino code kom txiav lub zog thaum lub ncov tam sim no ntawm> 3200 mAmps raug kuaj pom. H-choj tshwj xeeb hais txog qhov kev nkag siab tam sim no ntawm 377 uA rau 1 Amp hauv kev thauj khoom.

1.5 k ohm resistor yuav xa 0.565 volts rau Amp ntawm tus pin analog 6. Nrog 1023 cov kauj ruam ntawm cov lus sib piv, qhov no muab 0.565 * 1023 /5 = 116 rau Amp load.

A = 100 * (analogRead (AN_CURRENT)) / 116; A = A * 10; (muab cov txiaj ntsig hauv milliamps)

Cov load tam sim no hauv milliamps tau tshwm rau ntawm TFT

Tag nrho 4x4 cov keyboard suav nrog F1 rau F8 ua haujlwm thiab lwm 10 thaj chaw (1-19) los ntawm qhov '#' qhov tseem ceeb (ntxiv 10 rau tus lej zauv pib los ntawm loco 10).

Tus lej arduino suav nrog NMRA tus qauv rau kev qhia bytes.

Saib qhov txuas

www.nmra.org/sites/default/files/s-9.2.1_20…

(nplooj 6 yog qhov tseem ceeb tshwj xeeb)

Cov pob ntawv tau teeb tsa raws li tus lej ntawm cov kauj ruam nrawm, ntev / luv qhov chaw nyob thiab Kev Ua Haujlwm Pab Pawg cov lus qhia.

Txhua qhov kev qhia bytes tau ua ntej los ntawm kev hais ua ntej ntawm '1' khoom 11111111 (lossis pob ntawv tsis ua haujlwm) tom qab ntawd;

xws li 4 chaw nyob byte 0 00000011 0 00111111 0 10000011 0 10111111

sib npaug rau loco 3, 128 cov kauj ruam nrawm, mus rau tom ntej thiab nrawm 3 (qhov kawg byte yog qhov yuam kev tshawb xyuas XOR)

eg A 3 byte chaw nyob 0 00000011 0 10010000 0 10110011

sib npaug rau loco 3, ua haujlwm pab pawg 1, FL teeb ntawm ntxiv rau XOR byte (a '0' ntsis cais txhua byte)

Saib cov vis dis aus nthuav tawm rau thaj tsam 12.

Cov haujlwm F1 - F8 muaj nyob ntawm 'A' qhov tseem ceeb, DIR ('*' qhov tseem ceeb = kev qhia) FL ('0' qhov tseem ceeb = teeb) thiab qhov tseem ceeb '#' muab thaj tsam 10 txog 19 ntawm tus lej lej. Tam sim no tus 'D' tus yuam sij siv rau 'NTSHUAB NTSHAV'.

Ua tsaug rau ntau tus muab kev pabcuam hauv lub vev xaib rau cov peev txheej ntawm DCC cov ntaub ntawv thiab Arduino code.

Tshwj xeeb, txoj haujlwm no tau tshoov siab los ntawm Michael Blank thiab nws 'Yooj Yim DCC - lub chaw hais kom ua'

[Nco tseg: Nws muaj peev xwm ntxiv daim npav nco rau TFT zaub thiab hloov kho cov duab kom pom cov duab ntawm cov tshuab uas tau xaiv, txawm hais tias lub tsev qiv ntawv cov lej yuav tsum tau kho dua kom tsim kev nco ntau ntxiv rau daim duab. Kev kos duab tam sim no yog qhov siab tshaj plaws rau TFT Arduino Nano]

Thawj tus lej Arduino los ntawm Michael Blank yog rau ib lub cav, rau pem hauv ntej / thim rov qab nkaus xwb uas tsis muaj kev tswj hwm kev ua haujlwm, tsis muaj cov keyboard thiab tsis muaj zaub.

Kuv tau hloov kho cov cai kom suav nrog 1 - 19 lub cav, lub vijtsam tso saib, qhia, teeb, 8 lub zog, nres thaum muaj xwm ceev thiab pib txwv tam sim no.

LMD18200T tus choj tuaj yeem nqa txog 3 amps uas ua rau nws haum rau txhua qhov suav nrog G-scale (tsheb ciav hlau vaj). Lub hwj chim tseem ceeb thiab cov khoom siv hluav taws xob tsim nyog rau siv sab hauv tsev tsuas yog koj tsis tuaj yeem ua txhua yam huab cua pov thawj. Kuv muaj lub chaw nres tsheb hais kom ua nyob hauv tsev lub caij ntuj sov nrog kev tsheb nqaj hlau txuas xov hlau hla ntawm phab ntsa mus rau txoj kev taug.

Kauj Ruam 1: Arduino Code - Chaw Nres Nkoj Nrog Keypad

Kuv ua tsaug rau tvantenna2759 rau kev taw qhia tawm 2 qhov ua yuam kev hauv daim duab qhia chaw uas Arduino code tsis sib haum rau cov xov hlau, tam sim no hloov kho tshiab (21 Oct 2017).

Tam sim no ntxiv 16 qhov kev tawm mus rau Chaw Nres Nkoj. Saib cov lus qhia ntawm cov phiaj xwm phiaj xwm phiaj xwm phiaj xwm phiaj xwm siv Arduino Mini Pro module.

Kauj Ruam 2: Arduino Code - TFT Zaub

Cov duab hluav taws xob tseem zoo ib yam nrog cov cai hloov pauv los qhia qhov xwm txheej ntawm 16 qhov kev tawm. Nco tseg: Lub tsev qiv ntawv cov lej yuav luag tag nrho cov duab kos cim xeeb tawm hauv chav me me rau cov yam ntxwv tshiab. Yog tias leej twg muaj cov ntaub ntawv qiv ntawv zoo dua qub rau TFT siv ntawm no, thov qhia rau kuv paub.
