PIC16F18426 Compiler error.

[DirkB]

Hello,

I ported a project from PIC16F1825 to PIC16F18426. PIC16F18426 does not have MIDI component and DAC component functions. If I create a project with only these two components, I get an error message.

new project:

• https://www.flowcode.co.uk
  Error creating C source code:
  test-18426.c : 208 : error : Syntax error

Hello Dirk,

Thanks for letting us know, investigating for you now.

[BenR]

This should be fully resolved for you now in both v10 and v11.

Simply go to Help -> Library Updates to get the latest definition files.

Let us know if you come across any further issues.

Hi Ben,

The ported project now compiles without errors, thank you for that. Here is a very small program. It runs without errors in the simulation, but produces an error message during compilation. What have I overlooked?

• Error creating C source code:

thank you

Hello Dirk,

Great glad that solved the problem for you.

In your MIDI component properties there is no RX remap pin assigned which is causing your compilation error.

grrrh!!!

thanks ;o)
