ua PCBA + Hlau Harness - Shenzhen Fumax Technology Co., Ltd.

Peb ua ntau lub rooj tsavxwm nrog cov xaim teeb tsa, feem ntau cov neeg siv khoom tsuas yog xav tau nruab peb lub PCBA nrog cov xov hlau ntawm lawv lub thawv, tom qab ntawd ua tiav cov khoom tiav.

Case Study:

Cov neeg siv khoom: Brail

Board: PWREII

Board muaj nuj nqi: kev sib txuas lus boards.

Cov neeg siv khoom siv peb cov boards los nruab rau ntawm lub tshuab loj.peb tau ua boards nrog tag nrho cov xaim ntsia.14 kab ntawm txhua lub rooj tsavxwm.tus neeg siv khoom tuaj yeem yooj yim nruab rau ntawm lub tshuab, txuag kev siv zog ntau ntawm cov neeg siv khoom.

Hluav taws xob ntawm PCBAs, nrog LEDs.

14 xov hlau yog soldered ntawm txhua PCBA.

Yog li, yuav ua li cas solder tag nrho 14 xov hlau zoo thiab siv tau.Thaum xub thawj cov xov hlau tau soldered manually tab sis nws qeeb.Fumax engineers tsim cov khoom tshwj xeeb uas yuav tso cai rau cov xov hlau los ntawm cov tshuab yoj soldering.cov neeg siv khoom zoo siab heev nrog cov txiaj ntsig.

Cov txheej txheem kuaj Boards:

1. Abstract

Cov ntaub ntawv no yog tsim los tsim cov qauv kev xeem hauv kev tsim PWREII.

Nco tseg: Cables uas tsis muaj connectors yuav tsum tau pickled nyob rau hauv 1cm rau cov kev ntsuam xyuas yuav tsum tau nqa tawm thiab tom qab kev xeem, lawv yuav tsum tau txiav tawm kom lub cable yog cais.

2. JumpersKev teeb tsa

JP1 (1 thiab 2) enables zaub 1

JP3 (1 thiab 2) suav rau ob txoj hauv kev.

JP2 (1 thiab 2) rov pib suav.

3. Flashing lub firmware

3.1.Nruab cov ntaub ntawv "sttoolset_pack39.exe", muaj nyob rau hauv https://drive.google.com/open?id=0B9h988nhTd8oYUFib05ZbVBVWHc.

3.1.Txuas tus ST-Link/v2 programmer hauv PC.

3.2.Nrog lub hwj chim tawm txuas tus programmer's STM8 chaw nres nkoj ntawm PWREII's ICP1 chaw nres nkoj.

Hlau hlua 3
Hlau hlua 4

Ua tib zoo saib tus pin 1 ntawm tus programmer thiab lub rooj tsavxwm tus pin 1.

Hlau hlua 5

Saib tom qab (qhov twg cov xaim tuaj rau qhov txuas).

3.3.Fais fab lub cuab yeej rau

3.4.Khiav lub ST Visual Programmer app.

Hlau hlua 6

3.5.Configure zoo li daim duab hauv qab no:

Hlau hlua 7

3.6.Nyem rau hauv Cov Ntaub Ntawv, Qhib

3.7.Xaiv qhov "PWREII_V104.s19" archive

Hlau hlua 8

3.8.Nyem rau hauv Program, Txhua tab

Hlau hlua 9

3.9.Txheeb xyuas tias Firmware tau programmed kom raug:

3.10.Fais fab lub PWRE II tawm ua ntej disconnect tus programmer.

4.suav nrog PWSH pawg thawj coj saib(HLOCov nyhuv sensor)

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 uaKev Sib Txuas Lus

Nco tseg: Koj yuav xav tau RS485 rau USB converter

5.1.Download tau thiab nruab lub converter tsav tsheb.

5.2.Hauv Start menu -> Devices thiab printers

5.3.Kos rau hauv cov cuab yeej cuab yeej tus lej ntawm nws qhov chaw nres nkoj COM

5.4.Hauv peb qhov xwm txheej COM4.

5.5.Qhib qhov kev xeem PWRE II muaj nyob rau hauv “https://drive.google.com/open?id=0B9h988nhTd8oS1FhSnFrUUN6bW8”

5.6.Muab tus lej Serial chaw nres nkoj thiab nyem rau hauv "abrir porta".

5.7.Sau cov ntaub ntawv tus lej (6 tus lej rau ib lub thawv) hauv cov ntawv sau ib sab ntawm lub pob "escreve contadores".Nyem rau ntawm lub pob no thiab pom tias cov lej no raug xa mus rau lub txee.
