Micro-controllers ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob, vim tias lawv muaj peev xwm ua cov haujlwm hauv kev siv tshuab, tswj, ua cov duab, thiab lwm yam. Lawv siv yog loj heev. Muaj ntau tsev neeg ntawm micro-controllers, ib ntawm cov yog Microchip's PIC (Peripheral Interface Controller). PICs yog nrov heev vim tias lawv pheej yig thiab vim lawv tus yam ntxwv, piv txwv li lawv siv lub zog qis, oscillator sab hauv thiab cov cuab yeej txhim kho dawb. Nov yog qhov piv txwv ntawm qhov yooj yim heev 40 tus pin PIC programmer, nws tsuas xav tau 3 tus tiv thaiv:

Kauj ruam 1: Schematic

Raws li tau hais los saum no, tsuas muaj peb 4, 7k resistors txuas nrog ntawm DB9 txuas thiab PIC. Raws li cov txheej txheem, cov resistors no txuas nrog cov pins hauv qab no ntawm PIC: MCLR (1), PGC (39) thiab PGD (40). Tus lej naj npawb 8 los ntawm DB9 txuas tau txuas nrog PGD tus pin (40) hauv PIC. Tus programmer no ua haujlwm ntawm 5V DC. Yog li, qhov hluav taws xob sab nraud yuav tsum txuas nrog 2-pin txuas.

Kauj Ruam 2: Tsim

Peb siv KiCad software los tsim PCB, nws yog dawb xwb! Tom qab ntawd peb pib ua PCB, ua ntej peb luam tawm cov qauv ntawm daim ntawv acetate. Tom qab ntawd peb tau siv UV txoj hauv kev los hloov lub Circuit Court mus rau lub rooj tsavxwm thiab rau zaum kawg, peb txhim kho PCB nrog hlau perchlorate. Tom qab ntawd peb tau muab tag nrho cov khoom siv tso rau hauv qhov chaw: 1 - DB9 txuas; 3 - 4, 7k Resistors; 1 - 2 lub dav hlau txuas; 1 - 40 tus pin qhov (socket);

Kauj Ruam 3: Yuav Siv Li Cas

Nov yog cov kauj ruam siv tus programmer:

1. Txuas nws los ntawm kab txuas txuas mus rau lub khoos phis tawj; 2. Txuas tus PIC xav tau ntawm lub rooj tsavxwm, piv txwv li, PIC18F4550; 3. Siv tus IDE, zoo li MPLAB lossis MikroC piv txwv, sau, sau cov cai thiab tsim cov ntawv. HEX; 4. Dhau tus programmer software zoo li PICPgm, xa cov ntaub ntawv. HEX mus rau PIC.

Thiab koj mus, PIC tau npaj siv thiab koj tau txais tus programmer tshiab rau 40 tus pin PIC micro-controllers.
