Akwụkwọ ntuziaka a na-emetụta PmodRS232 rev. B
gafereview
Digilent PmodRS232 na-atụgharị n'etiti mgbagha dijitalụ voltage n'ogo ruo RS232 voltage etoju. A haziri modul RS232 ka ngwaọrụ nkwukọrịta data (DCE). Ọ na-ejikọ na ngwaọrụ ọdụ data (DTE), dị ka ọdụ ụgbọ mmiri na PC, na-eji eriri kwụ ọtọ.
Atụmatụ gụnyere:
- Standard RS232 DB9 njikọ
- Nhọrọ RTS na CTS ọrụ aka aka
- Obere PCB maka atụmatụ mgbanwe 1.0" × 1.3" (2.5 cm × 3.3 cm)
- 6-pin Pmod njikọ na UART interface
- Example koodu dị na resource center
Nkọwa ọrụ
PmodRS232 na-eji ya Maxim Integrated MAX3232 transceiver iji kwe ka bọọdụ sistemụ na-ekwurịta okwu na ngwaọrụ dakọtara UART ma ọ bụ ihe ndị ọzọ na-eji interface serial.
Mmekọrịta na Pmod
PmodRS232 na-ekwurịta okwu na bọọdụ nnabata site na protocol UART. Nhazi nke atụdo bụ ụdị nkwurịta okwu UART ochie ka a ga-achọ eriri crossover ma ọ bụrụ na ị na-ejikọta Pmod a na otu n'ime ndị isi UART Pmod raara onwe ya nye na bọọdụ usoro Digilent.
Enyere tebụl nkọwa na eserese maka PmodRS232 n'okpuru:
| Ntụtụ | Signal | Nkọwa |
| 1 | CTS | Kpochapụ izipu |
| 2 | RTS | Dị njikere iziga |
| 3 | TXD | Nyefee data |
| 4 | RXD | Nweta data |
| 5 | GND | Ala Na-enye Ike |
| 6 | VCC | Nkwanye ike (3.3V/5V) |
Isiokwu 1. Njikọ njikọ J1 nkowa pin.
| JP1 | JP2 | Nkwukọrịta |
| Ebupụrụ | Ntụtụ 1 na 2 na-agbakọta ọnụ | 3-waya nzikọrịta ozi |
| Ntụtụ 1 jikọọ na pin 1 nke JP2 na pin 2 ejikọrọ na pin 2 nke JP2 |
Ntụtụ 1 jikọọ na pin 1 nke JP1 na pin 2 ejikọrọ na pin 2 nke JP2 |
5-waya nzikọrịta ozi |
Isiokwu 2. Ntọala ngọngọ jumper.
Enwere ngọngọ jumper abụọ na PmodRS232; JP1 na JP2. Ihe mgbochi jumper ndị a na-enye ohere ka PmodRS232 na-ekwurịta okwu na ọrụ 3-waya ma ọ bụ 5. Mgbe a na-ebufe ihe mgbochi jumper na JP2 ma budata ngọngọ na JP1, mgbawa onboard nwere ahịrị RTS na CTS jikọtara ọnụ, na-egosi MAX3232 na ọ nweere onwe ya ịnyefe data mgbe ọ bụla ọ natara ma mee ka nkwurịta okwu 3-waya nwee ike. Ekwesịrị ibutu JP1 na nhazi a iji hụ na atụdo 1 na 2 na nkụnye eji isi mee Pmod adịghị mkpụmkpụ ọnụ nke nwere ike imebi bọọdụ sistemụ.
Nkwurịta okwu 5-waya chọrọ ka ejikọta pin 1 nke JP1 na pin 1 nke JP2, na pin 2 nke ma JP1 na JP2 jikọtara ọnụ, na-enye ohere nke ọma maka CTS / RTS aka aka n'etiti Pmod nkụnye eji isi mee na mgbawa on-board. . Ma waya nke ise na nhazi a na waya nke atọ na nkwurịta okwu 3-waya bụ akara akara ala.
Ike mpụga ọ bụla etinyere na PmodRS232 ga-abụrịrị n'ime 3V na 5.5V; Otú ọ dị, a na-atụ aro na a na-arụ ọrụ Pmod na 3.3V.
Akụkụ anụ ahụ
A na-ekewa ntụtụ ndị dị na nkụnye eji isi mee ihe 100 mil iche. PCB dị 1 inch n'ogologo n'akụkụ ya na ntụtụ dị na nkụnye eji isi mee na 1.3 inch n'ogologo n'akụkụ ya kwụ ọtọ na ntụtụ na nkụnye eji isi mee. Njikọ DB9 na-agbakwunye 0.25 inch ọzọ n'ogologo PCB nke kwekọrọ na ntụtụ na nkụnye eji isi mee.
