Error during compilation with SPI protocole on PIC 18F6***

[WalkOver]

Hello the Flowcode community !

I have lots of errors when I compiling program with SPI protocol on PIC 18F6*** and PIC 18F8*** ( I use PIC 18F6527 an 6622 ). When i compil the same program on pic 18F2*** or 18F4***, it works very well. I made a simple test program who just send an octet in SPI and i have the same problem with the last flowcode revision :

Please can you tell me what I can do to fix this problem ?

Thank you very much for your help !

Hello

The problem arises because these chips have 2 synchronous serial ports and therefore the registers are named slightly different to the other devices.

Please can you check which version of Flowcode 3 you are using. It is probable that this problem has been fixed in the latest releases of Flowcode (3.4.7).

If you want a quick fix then you can goto Edit -> Supplementary code and then copy the following lines of text into the defines section.

Code: Select all

#define sspbuf ssp1buf
#define sspcon1 ssp1con1
#define sspstat ssp1stat

Your program should now compile correctly.

Thank you for your Help.

I have the last Flowcode version ( 3.4.7.48 )

Nevertheless, I try to put your code into a define section and i still have this problem

If you use a SPI communication on a 18F6622, can you compile correctly ?

[Steve]

I've just tried this and it looks like the latest FCD file is incorrect - I'll ask Ben to fix this.

But I also tried Ben's workaround and this worked fine - the code compiled without error.

[WalkOver]

Can you send me your file please ? I could see the tips.
I really can't compile with this method. I should probably do something wrong.

[Steve]

It is attached. If it contains some wierd text, don't worry - I'm currently creating a Turkish version of Flowcode.

Thank you very much,

I realized my mistake. I used the AddDefines icon instead of the edit menu.

It compiles very well now !

Thank you Benj and steve.
