Senza amabhodi amaningi anezintambo ezifakiwe, imvamisa amakhasimende azodinga nje ukufaka i-PCBA yethu ngezintambo emabhokisini awo, bese umkhiqizo ophelile usuqedile.

Ucwaningo lwesigameko:

Ikhasimende: IBrail

Ibhodi: PWREII

Umsebenzi weBhodi: amabhodi wokuxhumana.

Ikhasimende lisebenzisa amabhodi ethu ukuthi afakwe emshinini omkhulu. senze amabhodi anezintambo zonke ezifakiwe. Izintambo eziyi-14 ebhodini ngalinye. ikhasimende lingafaka kalula emshinini, lilondoloze imizamo eminingi ohlangothini lwamakhasimende.

Izintambo kuma-PCBA, anama-LED.

Izintambo eziyi-14 zidayiswa kwi-PCBA ngayinye.

Ngakho-ke, ungazihlalisa kanjani zonke izintambo eziyi-14 kahle nangempumelelo. Ekuqaleni izintambo zazidayiswa ngesandla kepha yayihamba kancane. Onjiniyela beFumax baklame isici esikhethekile esizovumela izintambo ukuthi zidayiswe ngemishini yokufaka amagagasi. ikhasimende lijabule kakhulu ngemiphumela.

Izinqubo zokuhlolwa kwamabhodi:

1. Okufingqiwe

Lo mbhalo uhlose ukulinganisa ukuhlolwa lapho kwenziwa i-PWREII.

Qaphela: Izintambo ezingenazo izixhumi kufanele zifakwe ku-1cm ukuze kwenziwe izivivinyo futhi ngemuva kokuhlolwa, kufanele zinqunywe ukuze ikhebuli lihlukaniswe.

2. Amajumpers Ukucushwa

I-JP1 (1 no-2) inika amandla ukubonisa 1

I-JP3 (1 no-2) zibalwa ngazo zombili izindlela.

I-JP2 (1 no-2) isetha kabusha ukubala.

3. Ukukhanya kwe-firmware

3.1. Faka ifayela “sttoolset_pack39.exe”, elitholakala ku-https: //drive.google.com/open?id=0B9h988nhTd8oYUFib05ZbVBVWHc.

3.1. Xhuma i-ST-Link / v2 programmer ku-PC.

3.2. Ngamandla okucisha xhuma ichweba le-STM8 lohlelo echwebeni le-ICP1 le-PWREII.

Wire Harness3
Wire Harness4

Naka i-pin 1 yohlelo no-pin webhodi 1.

Wire Harness5

Ukubheka ngemuva (lapho izintambo ziza kusixhumi).

3.3. Nika amandla idivayisi

3.4. Qalisa uhlelo lokusebenza lwe-ST Visual Programmer.

Wire Harness6

3.5. Lungiselela njengesithombe esilandelayo:

Wire Harness7

3.6. Chofoza kufayela, vula

3.7. Khetha ingobo yomlando ye- “PWREII_V104.s19”

Wire Harness8

3.8. Chofoza kuhlelo, Wonke amathebhu

Wire Harness9

3.9. Bheka ukuthi i-Firmware ihlelwe kahle yini:

3.10. Nika amandla i-PWRE II ngaphambi kokunqamula unjiniyela.

4.     Ukubala usebenzisa ibhodi le-PWSH (IHOLO Inzwa yomphumela)

4.1. Passando-se o imã da direita para a esquerda verifique que o display incrementa a contagem na direção saída.

4.2. Passando-se o imã da esquerda para a direita verifique que o display incrementa a contagem na direção de entrada.

5.     RS485 Ukuhlolwa Kwezokuxhumana

QAPHELA: Uzodinga isiguquli se-RS485 to USB

5.1. Landa bese ufaka umshayeli wokuguqula.

5.2. Kumenyu yokuqala -> Amadivayisi namaphrinta

5.3. Bheka izakhiwo zedivayisi inombolo yetheku lakhe le-COM

5.4. Esimweni sethu COM4.

5.5. Vula uhlelo lokuhlola lwe-PWRE II olutholakala ku- “https://drive.google.com/open?id=0B9h988nhTd8oS1FhSnFrUUN6bW8”

5.6. Faka inombolo ye-serial port bese uchofoza ku- “abrir porta”.

5.7. Faka idatha yezinombolo (amadijithi angu-6 ngebhokisi ngalinye) ebhokisini lemibhalo eliseduze kwenkinobho “escreve contadores”. Chofoza kule nkinobho bese ubona ukuthi lezi zinombolo bezithunyelwa kwikhawunta.

5.8. Qhafaza ku- “Le Contadores”, uqinisekise ukuthi izinombolo ezikuma-counter ware zidluliselwe ebhokisini lombhalo eliseduze nale nkinobho.

QAPHELA: Uma lokhu kuhlolwa kuphumelele kusho ukuthi zombili ukuxhumana kwe-RS485 ne-TTL kuyasebenza.

6.     RS232 Ukuhlolwa kokuxhumana

6.1. Izinto ezidingekayo:

6.1.1. 1 DB9 isixhumi sesifazane

6.1.2. Intambo engu-1 AWG 22 enezintambo ezi-4

6.1.3. 1 PC enembobo ye-serial

6.2. Hlanganisa isixhumi njengesithombe esilandelayo:

Wire Harness13

6.3. Xhuma olunye uhlangothi lwentambo kuzintambo ze-PWREII's RS232.

Wire Harness14

QAPHELA: Uma une-RS232 to USB adapter awudingi ukuhlanganisa le ntambo.

6.4. Landela imiyalo kusukela ngo-5.1 kuqhubeke.

7.     Ukuhlolwa kohlelo lweshaja yebhethri

7.1. Ukuze wenze lokhu kuhlolwa, kufanele uvule ucingo olubomvu lwebhethri.

7.2. Faka i-multimeter ochungechungeni ngocingo olubomvu bese ukhetha isikali se-mA.

7.3. Xhuma uphenyo oluqondile ocingweni oluvela ku-PWREII kanye ne-probe ye-negaive ocingweni oluya ebhethri.

7.4. Bheka inani kusikrini se-multimeter:

Wire Harness15

Inani elifanele libonisa ukuthi ibheja liyashaja.

QAPHELA: Lapho ibhethri lingenalutho ngokuphelele ukuphakama kwamanje kufinyelela ku-150mA.

7.5. Gcina lokhu kuxhuma bese uvala ugesi.
