PICNODE board specs

Horcio FernandesJoo FortunatoLeonardo PedroTiago Pereira

Micro processor

- dsPIC30F4013

- Fcristal = 7,3728MHZ

- max clock: Fcristal * 16 / 4 = 29.4912 MIPS

Interfaces

Some interfaces are pin multiplexed

- Optical serial interface (Rx and Tx)

- CAN

- RS485 (Half Duplex)- RS232 (true RS232 from MAX232 or equivalent)

- I2C

- SPI

- RJ11 (for ICD2, a microchip programmer)

IO

Some IO features are pin multiplexed

- up to 8 power pull-down outputs (0.5A per output)

- up to 6 analog inputs

- up to 31 general purpose digital IO- up to 3 external interrupt sources


2/8

Board

- one push button for reset (SW2)

- one push button connected to general I/O pin (SW1)

- two monitoring led connected to I/O pins

Clock

- 7,3728MHZ cristal for uP clock (0% error in baud rates generation)

- 32,768KHz cristal (example applications: 1s real time clock (unix time format) or 1s period timer)

Communication speed

- optical: up to 1,8Mbaud (limited by pic clock)

- RS232 port: min 120kbps for HIN232CPZ (depends on RS232 converter)

- RS232 standard baud rates: 9600, 19200, 38400, 115200, 460800, 921600 (with appropriate

RS232 converter)

Programming

- 1st option:

. use microchip ICD2 connected to RJ connector

. work with MPLAB IDE

. programming jumpers must be in position 1

. programming switch must connect pins 1 and 2

- 2nd option:

. use serial straight through cable from PC serial port to picnode board D9 connector

. compile your code in MPLAB IDE

. use "WinPic - A PIC Programmer for Windows" to program the pic

. programming jumpers must be in position 3

. programming switch must connect pins 2 and 3 when programming

. programming switch must connect pins 1 and 2 when using the rs232 port

DIN 96 pins outputs

- Avcc: 5v used as reference for pic ADC. Maximum current out of these pins: 100mA

- Vcc_unreg: vcc voltage not regulated. Maximum current: 0.9A

- Vcc_5: 5v voltage supply to the pic. Maximum current: 0.8A

- 5V_pwr: regulated 5v output (7805). Maximum current: 1A

- Agnd: ground (0V) used as reference to the pic ADC- GND: general ground

- an0, an1, ...: inputs to the several ADC channels

- PwrDrv0 to PwrDrv7: power pulldown outputs

- canrx and cantx: can output and input directly from the pic

- can_h and can_l: differential can line from the can transceiver

- rx2 and tx2: uart output and input directly from the pic

- sdo: pic output to be used in rs485

- rs485_a and rs485_b: differential rs485 line from the rs485 transceiver

- int0, int1 and int2: pic external interrupt pins

- rc13 and rc14: pic general purpose IO
