2.3.2
There are two PIC16F877 firmware programs that can be demonstrated on the demo
board. These are:
• A vending machine that allows the uploading of data and responds to the
• A 250-byte secondary device (S) to primary device (P) data transfer. This
The 250-byte Secondary device (S) to Primary device (P) data transfer program has
two options. These are:
1. Transfer data from the Host Controller (PIC16F877) to the MCP2150 while the
2. Transfer 64 bytes of data from the Host Controller (PIC16F877) to the MCP2150
Option 2 will demonstrate higher S
Typical Primary devices include Palm or Pocket PC PDAs and laptop PCs with an IrDA
standard infrared port. The embedded system acts as an IrDA standard Secondary
device.
The PIC16F877 firmware follows the flow control of the host UART interface. These are
the signals between a Host Controller and a MCP2150 device.
The details of the vending machine firmware operation are discussed in
Section 2.3.2.1 “Vending Machine Program Description”.
The details of the “250 byte Secondary Device (S) to Primary Device (P) Data Transfer”
firmware operation are discussed in Section 2.3.2.2 “250-byte Secondary Device (S)
to Primary Device Data Transfer Program Description”.
Figure 2-5 shows the program flow that occurs to select between these two programs.
The MCP215X Data Logger Demo Board LCD module will display information on the
state of the firmware execution. This information includes queries for user input.
The selection of the program is dependant on the switches (SW2 and SW3) that are
depressed (see Figure 2-4).
TABLE 2-2:
The MCP2150/MCP2155 source code of the MCP215X Data Logger Demo Board is
available for download from the Microchip web site at www.microchip.com. This board
also supports the MCP2155 device with only a change of the PIC16F877 firmware. The
MCP2140 can be supported with some hardware modifications and changes to the
PIC16F877 firmware.
