The on-board ICSP connector allow you to program the PIC on the
board without pulling it of the socket, by ICSP programmer like PIC-
MCP, PIC-MCP-USB, PIC-PG1, PIC-PG2, PIC-PG3, PIC-PG4 or to
program and debug it with PIC-ICD2, PIC-ICD2-POCKET or PIC-ICD2-
TINY.
IMPORTANT: all programmers provide power supply through
ICSP connector during the programming PIC-P28-USB should not be
connected to USB. Of course PIC-ICD2 have option to not power the
target circuit and this option should be used when you debug your
application while connected to USB.
The oscillator circuit is made with 20 Mhz crystal oscillator, so you
can run your PIC at maximum performance.
The RESET circuit is made with simple RC circuit. Note that RESET
button should not be pressed while you program or debug the PIC!
PIC-P28-USB have user button for user input connected to PIC
microcontroller’s RA5 port. When RA5 port is initialized as INPUT you
will read “0” when the button is pressed and “1” when it is depressed.
Status LED is connected via jumper to PIC microcontroller’s RA0 port.
When your RA0 port is initialized as OUTPUT and set to “0” LED will
go ON, when RA0 port is set to “1” LED will go OFF.
PIC-P28-USB have handy GND pin for connection to oscilloscope.
All modem signals from FT232 are provided and could be used.
PIC-P28-USB have socket for I2C EEPROM which are connected to
RC4-SDA and RC3-SCL
