4.2.2 Programming the PIC16F1509
The PIC16F1509 can be programmed via the ICSP (In-Circuit Serial Programming)
connector marked with J23, with tools such as the PICkit™ 3 or compatible
debuggers/programmers. In case there are programming issues, consult
Chapter 5. “Troubleshooting” in this document.
The source code for the PIC microcontroller can be written using MPLAB
®
X IDE and
the XC8 C compiler that are available for download at http://www.microchip.com.
Part of the code, including for the I
2
C master, can be generated automatically using the
MPLAB Code Configurator plug-in.

C SLAVE ADDRESSES
This section lists the addresses of the I
2
C slave devices that are available on the
demonstration board. The values displayed in Tabl e 4- 1 are in the 8-bit form and can
be used directly as parameters during application development when calling the
MCP2221.DLL functions.
The 8-bit equivalent (write address) of a 7-bit I
2
C address is the result of a
left-shift-once (or multiplication by 2) of the 7-bit address.
