INTRODUCTION
This section answers some frequently asked questions concerning the configuration of
the MCP2515 to assist those who are new to the device.
FAQS
1. Why doesn’t the development tool successfully communicate on an
external bus?
There are several possible reasons why this is the case. The following are the
most common problems:
TABLE B-1:
COMMON BUS COMMUNICATION PROBLEMS
Condition
The MCP2515 is off the bus
(not in Normal mode).
The LPT port is not configured
correctly.
The bus rate is not set to match the
bus.
Fix
Basic template – Go on Bus button in the
“Bus Status” window.
Make sure LPT address is correct ( Options >
MCP2515 . ).
Basic template – Set the bus rate in the Bus
Status window.
Register template – change CNF registers.
Oscillator frequency not set to match Set the oscillator frequency
hardware (F OSC is required in bit rate ( Options > MCP2515... ).
formula).
Board is not connected to the
external bus.
Connect to the external bus using the DB9
labeled CAN.
Pinouts: CANH – pin 7, CANL – pin 2.
2. The node is acknowledging messages in the Basic template but not
displaying them.
The MCP2515 filters are not matching the incoming messages. This can occur
because the Reset MCP2515 on Open is deselected, causing the old register
contents (masks and filters) to remain unchanged when switching templates.
Press reset, or select the Reset MCP2515 on Open box and reopen the
template.
