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-P40-USB have user button for user input connected to PIC microcontroller’s RE2 port.
When RE2 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 RE1 port. When your RE1 port
is initialized as OUTPUT and set to “0” LED will go ON, when RE1 port is set to “1” LED
will go OFF.
PIC-P40-USB have handy GND pin for connection to oscilloscope.
All modem signals from FT232 are provided and could be used.
PIC-P40-USB have socket for I2C EEPROM which are connected to RC4-SDA and RC3-
SCL
On the schematic you will see PGM_SEL jumper, this is necessary because some PICs use
RB3 for ICSP-PGM signal others RB5, this is done by smd jumper on the back side of the
board which is soldered in position RB3 by default (PIC18F877 which is used for the demo
code), if your PIC use RB5 you should connect this jumper properly.
