PmodRS232™ Reference Manual
Yakadzokororwa Chivabvu 24, 2016
Iri bhuku rinoshanda kune PmodRS232 rev. B
Overview
Iyo Digilent PmodRS232 inoshandura pakati pedhijitari logic voltage mazinga kusvika kuRS232 voltage mazinga. Iyo RS232 module inogadziriswa sedhizaini yekutaurirana data (DCE) mudziyo. Iyo inobatanidza kune data terminal zvishandiso (DTE) zvishandiso, senge serial port paPC, uchishandisa yakatwasuka-kuburikidza netambo.
Zvimiro zvinosanganisira:
- Chibatanidza RS232 DB9
- Optional RTS uye CTS kubata maoko mabasa
- Diki PCB saizi yemagadzirirwo anochinjika 1.0" × 1.3" (2.5 cm × 3.3 cm)
- 6-pini Pmod yekubatanidza ine UART interface
- Example kodhi inowanikwa munzvimbo yekushandisa
Tsanangudzo Yekushanda
Iyo PmodRS232 inoshandisa iyo Maxim Yakabatanidzwa MAX3232 transceiver kubvumira bhodhi rehurongwa kutaurirana neUART inoenderana michina kana zvimwe zvikamu zvinoshandisa serial interface.
Kudyidzana nePmod
Iyo PmodRS232 inotaurirana nebhodhi rekugamuchira kuburikidza neUART protocol. Kurongeka kwepini ndiyo yekare UART yekutaurirana maitiro saka tambo yekuchinjika ichadikanwa kana ukabatanidza iyi Pmod kune imwe yakatsaurirwa UART Pmod misoro pane Digilent system board.
Iyo pinout tsananguro tafura uye dhayagiramu yePmodRS232 inopihwa pazasi:
| Pin | Signal | Tsanangudzo |
| 1 | CTS | Clear to Send |
| 2 | RTS | Yakagadzirira Kutumira |
| 3 | TXD | Transmit Data |
| 4 | RXD | Gamuchira Data |
| 5 | GND | Power Supply Ground |
| 6 | VCC | Kugovera Simba (3.3V/5V) |
Tafura 1. Connector J1 pini tsananguro.
| JP1 | JP2 | Kukurukurirana |
| Yakatururwa | Pini 1 ne2 dzakapfupikiswa pamwechete | 3-waya kutaurirana |
| Pini 1 yakabatana nepini 1 yeJP2 uye pini 2 yakabatana nepini 2 yeJP2 |
Pini 1 yakabatana nepini 1 yeJP1 uye pini 2 yakabatana nepini 2 yeJP2 |
5-waya kutaurirana |
Tafura 2. Jumper block settings.
Pane maviri jumper blocks paPmodRS232; JP1 uye JP2. Aya majumper block anobvumira iyo PmodRS232 kutaurirana mune angave matatu-waya kana 3-waya oparesheni. Kana iyo jumper block paJP5 inotakurwa uye bhuroka paJP2 raburitswa, iyo onboard chip ine RTS yayo uye CTS mitsetse yakasungirirwa pamwe chete, zvichiratidza kuMAX1 kuti yakasununguka kuendesa data pese painogashira chero uye inogonesa 3232-waya kutaurirana. JP3 inofanira kubudiswa mukugadzirisa uku kuti ive nechokwadi chokuti mapini 1 uye 1 pamusoro wePmod haana kupfupiswa pamwe chete izvo zvinogona kukuvadza system board.
5-waya kutaurirana kunoda kuti pini 1 yeJP1 yakabatana nepini 1 yeJP2, uye iyo pini 2 yezvose zviri zviviri JP1 neJP2 zvakasungwa pamwe chete, zvinogoneka kubvumira CTS/RTS kubata maoko pakati pemusoro wePmod uye iyo-bhodhi chip. . Ose ari maviri waya yechishanu mukugadziriswa uku uye waya yechitatu mu3-waya kutaurirana ndiyo yepasi chiratidzo mutsara.
Chero simba rekunze rinoshandiswa kuPmodRS232 rinofanira kunge riri mukati me3V uye 5.5V; zvisinei, zvinokurudzirwa kuti Pmod inoshandiswa pa 3.3V.
Muviri Dimensions
Mapini ari pamusoro wepini akapatsanurwa 100 mils apart. Iyo PCB yakareba 1 inch pamativi anoenderana nemapini ari pamusoro wepini uye 1.3 inches kureba pamativi perpendicular kumapini ari pamusoro wepini. Iyo DB9 yekubatanidza inowedzera imwe 0.25 inches pakureba kwePCB inofambirana nemapini pamusoro wepini.
