Bukana ea Litšupiso ea PmodRS232™
E ntlafalitsoe ka la 24 Motšeanong, 2016
Bukana ena e sebetsa ho PmodRS232 rev. B
Fetileview
Digilent PmodRS232 e fetolela lipakeng tsa digital logic voltage ho fihla ho RS232 voltagmaemo a. Mojule oa RS232 o hlophisitsoe joalo ka sesebelisoa sa likhokahano tsa data (DCE). E hokahana le lisebelisoa tsa data terminal (DTE), joalo ka serial port ho PC, e sebelisa mohala o otlolohileng.
Likarolo li kenyelletsa:
- Sehokelo se tloaelehileng sa RS232 DB9
- Mesebetsi ea boikhethelo ea RTS le CTS ea ho ts'oarana ka matsoho
- PCB e nyane bakeng sa meralo e tenyetsehang 1.0" × 1.3" (2.5 cm × 3.3 cm)
- Sehokelo sa 6-pin Pmod se nang le sebopeho sa UART
- Example khoutu e fumanehang setsing sa lisebelisoa
Tlhaloso ea Ts'ebetso
PmodRS232 e sebelisa mokhoa oa ho Maxim Integrated MAX3232 transceiver ho lumella boto ea tsamaiso ho buisana le lisebelisoa tse lumellanang le UART kapa likarolo tse ling tse sebelisang sebopeho sa serial.
Ho kopana le Pmod
PmodRS232 e buisana le boto ea baeti ka protocol ea UART. Tlhophiso ea lipini ke mokhoa oa khale oa puisano oa UART kahoo ho tla hlokahala cable ea crossover haeba u kopanya Pmod ena ho e 'ngoe ea lihlooho tse inehetseng tsa UART Pmod ho boto ea tsamaiso ea Digilent.
Tafole ea litlhaloso le setšoantšo sa PmodRS232 li fanoe ka tlase:
| Pin | Letshwao | Tlhaloso |
| 1 | CTS | Hlakileng ho Romela |
| 2 | RTS | E Itokiselitse ho Romeloa |
| 3 | TXD | Fetisetsa Lintlha |
| 4 | RXD | Fumana Boitsebiso |
| 5 | GND | Sebaka sa Phepelo ea Matla |
| 6 | VCC | Phepelo ea Matla (3.3V/5V) |
Letlapa la 1. Litlhaloso tsa phini tsa Connector J1.
| JP1 | JP2 | Puisano |
| E laoletsoe | Pins 1 le 2 li khutsufalitsoe hammoho | puisano ea 3-terata |
| Pin 1 e amanang le phini ea 1 ea JP2 le pin 2 e hokahaneng le phini ea 2 ea JP2 |
Pin 1 e amanang le phini ea 1 ea JP1 le pin 2 e hokahaneng le phini ea 2 ea JP2 |
puisano ea 5-terata |
Lethathamo la 2. Litlhophiso tsa jumper block.
Ho na le li-jumper blocks tse peli ho PmodRS232; JP1 le JP2. Li-jumper blocks tsena li lumella PmodRS232 ho buisana ka ts'ebetso ea terata e 3 kapa e 5. Ha jumper block ho JP2 e laetsoe 'me thibela ho JP1 e laolloa, chip ea onboard e na le mela ea eona ea RTS le CTS e kopantsoeng hammoho, e bontšang ho MAX3232 hore e lokolohile ho fetisetsa data neng kapa neng ha e fumana leha e le efe le ho nolofalletsa puisano ea 3-wire. JP1 e tlameha ho laolloa ho tlhophiso ena ho netefatsa hore lithakhisa 1 le 2 hloohong ea Pmod ha li khutsufatsoe hammoho tse ka senyang boto ea sistimi.
Puisano ea terata e 5 e hloka hore phini ea 1 ea JP1 e hokahane le phini ea 1 ea JP2, le hore phini ea 2 ea JP1 le JP2 ka bobeli li tlameletsoe hammoho, e leng se lumellang ho ts'oarana ka matsoho ka CTS/RTS pakeng tsa hlooho ea Pmod le chip e holim'a board. . Ka bobeli terata ea bohlano tlhophisong ena le terata ea boraro puisanong ea terata e 3 ke mohala oa lets'oao la fatše.
Matla afe kapa afe a kantle a sebelisoang ho PmodRS232 a tlameha ho ba ka har'a 3V le 5.5V; leha ho le joalo, ho khothaletsoa hore Pmod e sebelisoe ho 3.3V.
Litekanyo tsa 'Mele
Lithakhisa tse hloohong ea phini li arohane ka limithara tse 100. PCB e bolelele ba lisenthimithara tse 1 ka mahlakoreng a bapileng le lithakhisa tsa hlooho ea phini le bolelele ba lisenthimithara tse 1.3 mahlakoreng a pota-potileng lithakhisa tse hloohong ea phini. Sehokelo sa DB9 se eketsa bolelele ba lisenthimithara tse 0.25 ho bolelele ba PCB bo bapileng le lithakhisa holim'a hlooho ea phini.
