Tam sim no koj tau npaj tiav los ua txoj haujlwm. Rov qab mus rau lub ntsiab lus tseem ceeb los ntawm ob npaug nias "BYOC-I" hauv Explorer Pane. Khiav thiab Pib dua cov tswv yim yuav tsum yog "0" kom pib. Siv lub Poke Tool, xub hloov Pib dua rau "1" tom qab ntawd rov mus rau "0". Qhov no ua rau pib chaw nyob 0x0000 thiab npaj BYOC-I Circuit Court rau kev ua tiav. Tam sim no poke cov lus nkag mus rau "1" thiab qhov program yuav ua tiav. (Faj seeb: Koj lub ntsiab yuav tsum tau coj mus Tswj -K ib zaug kom pib lub Logisim moos. Qhov no yog qhov tshwj xeeb uas tso cai rau koj kom nres lub Logisim moos thiab nqis los ntawm txoj haujlwm los ntawm kev kov Control-T ntau zaus. Sim nws qee zaum!)

Lub Logisim moos tau teeb tsa rau ntau qhov ntau zaus. Raws li rub tawm nws yog 8 Hz (8 mus rau ib pliag). Txoj hauv kev BYOC-Kuv lub khoos phis tawj tau tsim, txhua qhov kev qhia yuav siv plaub teev mus los kom tiav. Yog li, los xam BYOC-Kuv nrawm, faib lub moos zaus ntawm 4. Ntawm 8 Hz, nws qhov nrawm yog 2 cov lus qhia ib pliag. Koj tuaj yeem hloov lub moos los ntawm txhaj "Simulate" ntawm lub cuab yeej bar thiab xaiv "Zis Zaus". Qhov ua tau yog 0.25 Hz txog 4100 Hz. Kev qeeb qeeb ntawm 8 Hz tau xaiv yog li koj tuaj yeem saib cov suav hauv A register.

Qhov siab tshaj plaws ntawm BYOC-Kuv simulation (~ 1000 cov lus qhia ib pliag) qeeb heev piv rau cov khoos phis tawj niaj hnub no. Kho vajtse version ntawm BYOC lub computer piav qhia hauv kuv phau ntawv ua tiav ntau dua 12 lab cov lus qhia ib pliag!

Kuv vam tias Cov Lus Qhia no tau piav qhia lub tshuab cov lus tsis zoo thiab muab kev nkag siab rau hauv yuav ua li cas khoos phis tawj ua haujlwm ntawm lawv qib pib. Txhawm rau txheeb xyuas koj qhov kev nkag siab, sim sau ob txoj haujlwm hauv qab no.

  1. Sau qhov program uas pib ntawm 5 thiab suav mus rau 0. (ANS. Count5to0.txt hauv qab no)
  2. Pib ntawm 2, suav los ntawm 3 kom txog rau tus lej ntau dua 7. Koj tuaj yeem ua tus lej lej siab me ntsis, txheeb xyuas 8 paub tias nws yuav tsaws rau ntawd ces rov pib dua. Sau koj cov haujlwm hauv ntau txoj hauv kev uas tau sim tiag tiag yog tias suav "tshaj" tus lej tshwj xeeb. Hint: Tshawb nrhiav qhov tshwm sim thaum rho tawm ua rau tus lej tsis zoo, hais 8 - 9 = -1 piv txwv. Tom qab ntawd sim nrog qhov laj thawj THIAB sim seb MSB hauv tus lej 8-ntsis yog "1". (ANS. ExcessCount.txt)

Koj puas tuaj yeem xav txog lwm yam teeb meem nyuaj rau BYOC-Kuv lub khoos phis tawj? Muab nws cov kev txwv, nws tuaj yeem ua dab tsi ntxiv? Qhia koj cov kev paub nrog kuv ntawm [email protected]. Yog tias koj xav siv coding microprocessors, txheeb xyuas kuv lub vev xaib www.whippleway.com. Muaj kuv nqa lub tshuab coding rau cov txheej txheem niaj hnub zoo li ATMEL Mega series siv hauv Arduinos.
