INTRODUCTION:
PIC-P8 board is low cost development board, which allow you to
prototype and develop code for all Microchip’s PIC microcontrollers
with 8 pins.
What you can do with PIC-P8? A lot of stuff let’s see what we have:
PIC-P8 have RS232 connector and driver, so you can interface your
PIC microcontroller to other embedded or PC with RS232. The PIC-P8
RS232 driver is made with tricky schematic to reduce the cost and the
negative RS232 level is generated using the opposite RS232 driver
negative level, thus to operate the opposite driver should be real
RS232 driver i.e. you can connect PIC-P8 to computer or other board
with RS232 driver but if you connect two PIC-P8 together they will not
talk to each other as none of them is able to produce negative voltage
levels.
PIC-P8 have also external EEPROM which could be connected to PIC
on the board via two SMD jumpers, as J2 and J3 share same pins as
the ceramic resonator if you want to use I2C you must run on internal
oscillator.
This board is so small that it have no ICSP connector i.e. to program
the PIC you should pull it from the socket and use programmer with
ZIF socket like PIC-MCP, PIC-MCP-USB, or PIC-PG2, PIC-PG3.
The power supply circuit have voltage regulator and could be powered
with +9-25VDC. The polarity is written on the silkscreen. There is
protection diode so if you connect the power supply reverse nothing
wrong will happend.
The oscillator circuit is made with 4 Mhz ceramic resonator, so you
can run your PIC at maximum performance.
GP0-GP5 are available next to prototype area and you can solder
additional circuits easy to the microcontroller.
