Configuring the Chip

The chip can be configured from within 'Project Options' on the 'Build' menu.

Please note that it is important to check the configuration before downloading to a chip.

Please ensure that the chip type and oscillator type are correct for your program as these are the main source of user problems.

Configuring the chip for PICmicros

Clicking on the Configure button from within the Project Options calls up the Configuration page.

The configuration page can be used to:

Specify the chip being used

Set the oscillator type required

Enable/disable timers

Set which version of Matrix development board you are using (the options button at the bottom)

If you are using Flowcode for the very first time, or have changed development boards, you may need to check the options to set which board you are using.

Other options are also available (see the help file for details).

More information can be found in the help file, which can be accessed from the '?' help button in the lower left of the screen.

Manually configuring the chip for PICmicros

Click here for help with switching off the default configuration options that use PPP.

Once you have disabled the default configuration options you can enter your own configuration data. For the PICmicro this data will be sent to the chip every time you perform a compile to chip operation.

An example configuration word for the PIC16 series is

0x2007, 0x3FFC

The 0x2007 is the location in memory of the configuration word and the 0x3FFC is the configuration word itself.

An example set of configuration words for the PIC18 series is

0x300000, 0x00

0x300001, 0x22

0x300002, 0x0D

0x300003, 0x0E

0x300004, 0x00

0x300005, 0x00

0x300006, 0x80

0x300007, 0x00

0x300008, 0x0F

0x300009, 0xC0

0x30000A, 0x0F

0x30000B, 0xE0

0x30000C, 0x0F

0x30000D, 0x40

Configuring the Chip for AVRs

The chip can be configured from the Configure option in the chip menu.

Please note that it is important to check the configuration before downloading to a chip.

Configuration settings for individual devices may be represented by 1, 2 or 3 bytes

The function of many of the individual configuration bits are also device dependent.

The data sheet for the relevant target device should be consulted before sending configuration data.

The default setting is configured to send the hex value 0xdf (223 decimal) to parameter location 0

The parameter locations are:

0 = Fuse High Byte (hfuse)

1 = Fuse Low byte (lfuse)

2 = Extended fuse Byte (efuse)

An example of 3 bytes of configuration data is shown below

OK and Send

Save the configuration data and send to the target device

OK

Confirm the configuration data but do not send to the target device

Note: Configuration memory might have a lower endurance than program memory. Only send configuration data when changes are required.
