NXP LPC1768 Pūnaehana Hoʻomohala Pūnaehana Manual
ʻŌnaehana Overview
ʻO ka LPC1768 Industrial Reference Design (IRD) kahi kahua i manaʻo ʻia i nā ʻōnaehana i hoʻopili ʻia ma RTOS. Hoʻolālā ʻia e pili ana i kahi manaʻo maʻalahi "Core" a me "Base" Printed Circuit Board (PCB), e hōʻike ana i ka nui o nā hana ʻōnaehana a me nā protocol kamaʻilio uea i loaʻa i nā noi i hoʻopili ʻia i kēia lā. Hiki i ka hoʻolālā maʻalahi ke hoʻololi i nā papa kumu a me nā papa kumu, nā hōʻike, a me nā kī kī e like me ka mea e pono ai ka noi i manaʻo ʻia. Hoʻohana ʻia ke kahua e kahi lako mana 5VDC waho a hāʻawi i ka circuitry e ana i ka hoʻohana ʻana o 3.3VDC i kēia manawa i ka wā e hana ana i ka paepae ma nā ʻano ʻano like ʻole. Hoʻokō ʻia ka hoʻomohala polokalamu a me ka debugging me ka hoʻohana ʻana i kahi JTAG ka pilina a me ke kaiapuni hoʻomohala Keil IDE. Hoʻohui ʻia ka ʻoihana circuitry e hoʻomaʻamaʻa i ka In-System-Programming (ISP), e ʻae ana i ka hoʻouka maʻalahi o nā polokalamu a hōʻike ʻia ma ka paepae.
Nā hiʻohiʻona o ka mana 1.3 kit:
- NXP-hoʻolālā (PCB ʻōmaʻomaʻo) LPC1768 papa kumu
- NXP-hoʻolālā papa (PCB ʻōmaʻomaʻo).
- He papa kī kī kelepona
- He modula LCD 20X4
Hāʻawi ka paepae i nā polokalamu hōʻike e hana i nā hoʻokolohua hana o nā hiʻohiʻona microcontroller, e like me Ethernet, USB Devices, UART, I²C, ADC, a me nā awa GPIO. I ka wā e hiki mai ana, e kākoʻo ka paepae i ka Micrium μC/OS-II Real-Time Operating System (RTOS), a hāʻawi i ke kākoʻo polokalamu no 10/100Base Ethernet, USB Host/Device, CAN, RS-232, a me I2C nā kuʻina kamaʻilio uea. Eia kekahi, hāʻawi ka paepae i nā interface maʻalahi no:
- Nā Hōʻike Hōʻike Hōʻikeʻo Vacuum Fluorescent (VFD) a i ʻole Liquid Crystal Displays (LCD)
- Hoʻonui UART
- Hoʻonui I2C
- ʻO nā lako polokalamu pili pono ma o nā poʻomanaʻo pili ma ka papa papa
Ka houluulu ana i ka Lako
Papa Hoʻopili
Aia ka pahu IRD i kēia mau mea:
- LPC1768 "Papa Papa Hana Hana"
- NXP Industrial Reference Design (IRD) "Baseboard", version 1.3
- Hōʻike LCD Lumex kumu hoʻohālike # LCM-S02004DSR
- He kaula lipine hōʻike (i hui ʻia ma ka Hōʻike LCD/VFD)
- NXP I2C papa kī, mana 1
- ʻIke wela o waho (2N3906-type ʻulaʻula/keʻokeʻo ʻike wela wela)

E hoʻokaʻaʻike i kāu mea hoʻolako inā nalo nā ʻāpana. Hiki i ka pahu ke hoʻokomo i nā ʻāpana ʻē aʻe e like me ka NXP pūʻolo i kēia pahu me nā paepae kuhikuhi ʻē aʻe (e laʻa me CAN Board, DALI Solid State Lighting Board, etc.). Inā hoʻokomo ʻia nā ʻāpana ʻē aʻe, e ʻike i ke alakaʻi e pili ana i kēlā paepae. Hiki ke loaʻa ke alakaʻi ma ka CD i hoʻokomo ʻia.
ʻAha ʻ Kitlelo Kit
E ʻoluʻolu e heluhelu pono i kēia mau ʻōlelo aʻoaʻo hui. ʻO ka hahai ʻole ʻana i kēia mau ʻōlelo aʻoaʻo hiki ke hana pono ka paepae. Pili nā ʻōlelo aʻo i ka paepae IRD wale nō. ʻO ka code hōʻike hōʻike IRD i hoʻolālā ʻia i loko o ka LPC1768 MCU e hiki ai iā GPIO LED "Blinky" a hāʻawi i kahi kumu no nā mea kūʻai aku e hoʻomaka i kā lākou LCP17xx hoʻomohala.
E hoʻohui i nā papa ma lalo nei e like me ka hōʻike ʻana ma ka Figure 1 (ʻaoʻao aʻe):
- Hōʻike LCD: Hoʻohui ʻia iā J_VFD
- I2C Keypad: Hoʻohui ʻia iā J_KEYPAD
- ʻIke wela o waho: Hoʻohui ʻia iā J_TEMP (Uila ʻulaʻula iā D+, Keʻokeʻo iā D-)
E hōʻoia i ka paʻa ʻana o nā mea lele ma lalo nei
| Kaʻa lele | Hoʻohui Paʻamau | wehewehe |
| JP2 | Hoʻopili ʻia ka mea lele | Hoʻohana ʻia no ICC ana ma ka paepae IRD ke hemo |
| JP18 | Hoʻohui ʻia nā pine 1&2 | Hiki iā 3.3VDC mai luna hoʻoponopono |
| JP19 | Hoʻohui ʻia nā pine 1&2 | Hiki iā 5.0VDC mai waho mai ka mana o Condor. |
| J_VDISP | Hoʻohui ʻia ka Pin 2&3 | Hāʻawi iā 5.0VDC i ka hōʻike LCD |
| VREF | Hoʻopili ʻia ka mea lele | Hāʻawi i ka pilina ADC/DAC VREF i ka microcontroller |
Ma mua o ka neʻe ʻana i ka ʻanuʻu 3, e hōʻoia i ka hahai pono ʻana o nā ʻōlelo aʻoaʻo a pau i wehewehe ʻia ma ka ʻanuʻu 1, nā pilina paʻa, a me ka hoʻonohonoho Jumper Step 2. ʻO ka hahai ʻole ʻana i kēia mau ʻōlelo aʻoaʻo hiki ke hana pono ka paepae
- Hoʻohui i ka lako mana Condor 5VDC waho i JPWR (2.5mm plug)
- E kali i kekahi mau kekona no ka mana o ka ʻōnaehana a nānā i nā LED ʻehā ma ka ʻaoʻao hema o lalo o ka baseboard ma luna o nā hoʻololi pihi 4. Pono lākou e kukuli ON mai ka hema a i ka ʻākau a laila OFF mai ka hema a i ka ʻākau. Ma ka hoʻoponopono ʻana iā AD0 (VR1), hiki iā ʻoe ke hoʻololi i ka nui o nā kukui uila.
- ʻO ka Heartbeat LED (ke kihi ʻākau lalo o ka base PCB) pono ke kukuli i ka 1Hz.
Pono nā LED e ON
- 5VPWR (Hula ʻulaʻula aia ma ka waena waena o ka Papa Base)
- 3V3_PWR (Ke kukui ʻulaʻula aia ma lalo waena o ka Papa Base)
- USB_PWR (Ke kukui ʻōmaʻomaʻo aia ma lalo o ka Papa Base)
Hoʻoponopono pilikia
ʻO kekahi mau pilikia maʻamau i hiki ke loaʻa i ka wā e hana ana i ka IRD:
Nā pilikia pili i nā lako
- Pono e hoʻopili ponoʻia ka papa kī a me ka LCD i ka "Baseboard". E nānā i ka ʻāpana o kēia manual no ka ʻike hou aku
- Pono e hoʻonohonoho ʻia nā mea lele a pau e like me ka pauku 2.2 o kēia manual
- ʻAʻole e pane ka papa kī inā wehe ka mea hoʻohana a hoʻopaʻa hou iā ia i ka wā e paʻa ana ka IRD. Ke hana ʻia kēia, e hoʻohaʻahaʻa i ka papa a hoʻāla hou
ʻIke a me nā palapala ma nā CD
Palapala
Aia i loko o ka pahu kahi kope o kēia QuickStartQuickStart Guide. Schematics, Bill of Material, Gerber files no ka Baseboard, IRD User Interface html web ʻaoʻao, a me nā modula aʻo no nā hana nui o ka paepae IRD hiki ke loaʻa ma ka NXP webkahua: http://www.standardics.nxp.com/support/boards/ird/
Pūnaehana – Keil
Ua hoʻomohala ʻia ka polokalamu kit IRD LPC1768 me ka hoʻohana ʻana i KEIL uVision3 version 3.5. Hāʻawi ʻo Keil i kahi mana hoʻāʻo 60-lā, 256kB no nā mea kūʻai aku e hoʻohana ana i ka pahu IRD.
No ka hoʻouka ʻana i ka Keil IDE e hele i: https://www.keil.com/demo/eval/arm.htm
- E hahai i nā kuhikuhi ma ka pukaaniani Auto-Installer.
- I ka wā o ke kaʻina hana, pono e hoʻopaʻa inoa i ka huahana me Keil e loaʻa ai ke kī laikini no ka IDE. E noi ʻia ʻoe e hoʻokomo i ka helu PSN i hāʻawi ʻia i loko o kēia kit (lepili me kahi helu serial 15-helu) e hoʻopaʻa inoa i ka mana hoʻāʻo o uVision.
- A laila e loaʻa iā ʻoe ke kī laikini no ka mea hana ma o ka leka uila. He 24 hola paha kēia e hana ai.
Pūnaehana – ULINK-ME Debugger
ʻO ka ULINK-ME Debugger i hoʻokomo ʻia i loko o ka pahu IRD e ʻae i ka hoʻopiʻi code a me ka hoʻonohonoho ʻana o ka microcontroller LPC1768 Cortex-M3.
- Hoʻohui i ka ULINK-ME i kahi awa USB PC
- Hoʻohui i ka JTAG mea hoʻohui i ka JTAG awa ma ka IRD Base Board
Nā Mea Hou a me nā Palapala
