Hi,

I build a system which is using an i2c graphical display and 6 x MCP23017 on the same i2c bus.
For each expander i build a macro. First five expanders are working fine.
When i initialized the sixth one, i got the bellow error message:

0: (499) undefined symbol:
_FC_CAL_I2C_Master_Init_7(Flowcode1.obj)
(908) exit status = 1
(908) exit status = 1

C:\Program Files (x86)\Microchip\xc8\v2.05\bin\xc8.exe reported error code 1

Autoclose turned off

I checked the component setup for each expander and there is no error.
I build a small test program, i got the same error.
Any idea is welcomed.

best regards,

Tiberiu

I solved the problem by creating my own component to control six MCP23017, via 12c bus.
But the Flowcode component still, has a problem with controlling more than 5 expanders.
And...would be nice to solve this issue.

best regards,

Tiberiu

Can you please say what have you changed in your component?
Was it the i2c address problem in FC8?

Hello,

The problem is caused by the CAL layer, currently we only allow 6 x SPI or 6 x I2C channels.

I have now increased this limitation to 10 via the update system.

Hi Benj,

As usual very helpful.
Update done, tested and functional.

thank you,
