Hi Benj,

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

thank you,

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

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(Flowcode...

Hi Martin,

I didn't know that is possible to go back so easily.
With the original file compiles ok.

thanks for the tip.

After today update i have the bellow compiling error: Microchip MPLAB XC8 C Compiler (Free Mode) V1.45 Build date: Nov 15 2017 Part Support Version: 1.45 Copyright (C) 2017 Microchip Technology Inc.

I still have a problem, i read only "0" value from RE3 (with hardware pull-up added). The conclusion regarding RE3 pin of PIC18F26K80 (28-pin) is this: "Note: PORTE is unavailable on 28-pin devices" quote from data sheet, page 181. I found an errata where is clearly stated: if MCLR pin is off, input...

Because i want to understand more about this subject, from where did you get the info?
It is useful for future similar issues, maybe i'll be able to solve them faster.

Hi Martin,

Your solution solved my problem.
I compared the existing header file with your uploaded header file and "trisE" register declarations are missing.
This was the reason for the error.

thank you

Hi, I try to read the state of PortE 3 (input only) but i get the bellow message from the compiler. I have no issue with the other Ports. { Control module v1.0.c: 33: __config("__PROG_CONFIG", "pic18", 0x2, 0x74FE); ^ (1386) unable to determine the semantics of the configuration setting "WDTPS" for ...

Ok Ben,

I understand were the problem is.
I already found a replacement (18f26K80).
Thank you for explanations.

The error code list is shorter but still there. If i can help in another way, besides compiling and posting error messages, just let me know. TMR0 was used for interrupt. Flowcode1.c: main() 98: T0CONbits.T0CS = 0; ^ (192) undefined identifier "T0CONbits" ^ (196) struct/union required 99: T0CONbits....

Hi Benj, I copied the file. Without using the interrupt the code is compiled successfully. With TMR0 interrupt activated error message is: Flowcode1.c: main() 102: T0CONbits.T0CS = 0; ^ (192) undefined identifier "T0CONbits" ^ (196) struct/union required 103: T0CONbits.T0SE = 1; ^ (196) struct/union...

Hi Benj, I tried your suggestion and the result is below: http://www.matrixtsl.com Launching the compiler...

Your suggestion worked. But, the predefined eeprom data are always written from address 8, not from address 0, as expected. 00 FF FF FF FF FF FF FF 2D B6 0A 64 2D B6 0A 64 2D B6 0A 64 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF...

Hi, I have to predefine 2 constant values in the internal eeprom of a PIC18F25K50. For this i used supplementary code, definition and functions declarations where i wrote: #pragma DATA _EEPROM, 45, 182, 28, 45 The problem is at compiling: Ver3.1.c: 442: #pragma DATA _EEPROM, 45, 182, 28, 45 ^ (335) ...
