PmodRS232™ Reference Manual
Inasinthidwa pa Meyi 24, 2016
Bukuli likugwira ntchito ku PmodRS232 rev. B
Zathaview
Digilent PmodRS232 imatembenuka pakati pa digito logic voltage mazinga mpaka RS232 voltage nsi. Module ya RS232 imapangidwa ngati chipangizo cholumikizirana ndi data (DCE). Imalumikizana ndi zida za data terminal (DTE), monga doko la serial pa PC, pogwiritsa ntchito chingwe chowongoka.
Zina mwazo ndi:
- Cholumikizira chokhazikika cha RS232 DB9
- Zosankha za RTS ndi CTS kugwirana chanza
- Kukula kwa PCB yaying'ono pamapangidwe osinthika 1.0" × 1.3" (2.5 cm × 3.3 cm)
- 6-pin Pmod cholumikizira chokhala ndi mawonekedwe a UART
- Example code ikupezeka mu Resource Center
Kufotokozera Kwantchito
PmodRS232 imagwiritsa ntchito Maxim Integrated MAX3232 transceiver kulola gulu ladongosolo kuti lizilumikizana ndi zida zofananira za UART kapena zida zina zomwe zimagwiritsa ntchito mawonekedwe a serial.
Kulumikizana ndi Pmod
PmodRS232 imalumikizana ndi gulu lokhala nawo kudzera pa protocol ya UART. Kukonzekera kwa zikhomo ndi njira yakale yolankhulirana ya UART kotero kuti chingwe chodutsa chidzafunika ngati mutagwirizanitsa Pmod iyi ku imodzi mwa mitu yodzipatulira ya UART Pmod pa bolodi la Digilent system.
Gome lofotokozera ndi chithunzi cha PmodRS232 zaperekedwa pansipa:
| Pin | Chizindikiro | Kufotokozera |
| 1 | Zotsatira CTS | Zomveka Kutumiza |
| 2 | Zithunzi za RTS | Okonzeka Kutumiza |
| 3 | TXD | Tumizani Data |
| 4 | Mtengo RXD | Landirani Zambiri |
| 5 | GND | Malo Opangira Mphamvu |
| 6 | Chithunzi cha VCC | Magetsi (3.3V/5V) |
Table 1. Mafotokozedwe a pini a Cholumikizira J1.
| Mtengo wa JP1 | Mtengo wa JP2 | Kulankhulana |
| Zotsitsa | Pin 1 ndi 2 amafupikitsidwa pamodzi | 3-waya kulankhulana |
| Pin 1 yolumikizidwa ndi pin 1 ya JP2 ndi pini 2 yolumikizidwa ndi pin 2 ya JP2 |
Pin 1 yolumikizidwa ndi pin 1 ya JP1 ndi pini 2 yolumikizidwa ndi pin 2 ya JP2 |
5-waya kulankhulana |
Table 2. Zosintha za jumper block.
Pali ma jumper awiri pa PmodRS232; JP1 ndi JP2. Ma jumper awa amalola PmodRS232 kuti ilumikizane ndi waya wa 3 kapena 5-waya. Pamene chipika chodumphira pa JP2 chatsitsidwa ndipo chipika pa JP1 chikutsitsidwa, chipboard chip chimakhala ndi mizere yake ya RTS ndi CTS yomangirizidwa palimodzi, kusonyeza MAX3232 kuti ndi yaulere kusamutsa deta nthawi iliyonse ikalandira chilichonse ndikuthandizira 3-waya kulankhulana. JP1 iyenera kutulutsidwa mu kasinthidwe kameneka kuti zitsimikizire kuti zikhomo 1 ndi 2 pamutu wa Pmod sizifupikitsidwa palimodzi zomwe zingathe kuwononga bolodi la dongosolo.
Kuyankhulana kwa mawaya 5 kumafuna kuti pini 1 ya JP1 ilumikizidwe ku pini 1 ya JP2, ndi kuti pini 2 ya JP1 ndi JP2 zonse zimangiriridwa palimodzi, kulola kugwirana chanza kwa CTS/RTS pakati pa mutu wa Pmod ndi chip pa bolodi. . Onse waya wachisanu mu kasinthidwe uku ndi waya wachitatu mu 3-waya kulankhulana ndi mzere chizindikiro pansi.
Mphamvu iliyonse yakunja yogwiritsidwa ntchito ku PmodRS232 iyenera kukhala mkati mwa 3V ndi 5.5V; komabe, tikulimbikitsidwa kuti Pmod igwiritsidwe ntchito pa 3.3V.
Miyeso Yathupi
Mapini pamutu wa pini amatalikirana mamilimita 100. PCB ndi 1 inchi utali m'mbali kufanana ndi zikhomo pa mutu wa pini ndi 1.3 mainchesi utali kumbali perpendicular mapini pa mutu pini. Cholumikizira cha DB9 chimawonjezera mainchesi 0.25 kutalika kwa PCB yomwe ili yofanana ndi mapini pamutu wa pini.
