SPI V1.4 problem

Hi, in the flow chart the SPI module 1.4 seems not to work as an output in projets where the old 1.1 or 1.2 version used to work fine.
Can this be a problem of my update, or maybe just a graphics one?
May I replace the 1.4 with the old one?
Thank you.

Hello Polanco
What are you trying to control via the SPI?
Which PICmicro are you using?
Which version of Flowcode are you using?

Hi Ben.
My Flowcode is 3.22 and I'm tryng to send the conversion of an analog input thru s,pi to a digital potentiometer.
Very simple and used to work fine in a Flowcode v3 demo version with a version 1.1 of spi midule.
Now i bought the software, updated to 3.22, whit 1.4 spi module and made a similar project with 16f917 or 16f877 pics.
No numbers apear at the spi output.
It can be something of my instalation.
The projet starts SPI, samples A/D, Reads A/D to a variable, Send char same variable via spi. Loop from second instruccion.

Hello Polanco
The latest version of Flowcode is 3.3.4.44. Would you mind updating to the latest version and see if the problem still remains.
Is the problem present on both the 16F877 and the 16F917?
If the problem is still there after you have updated then please could you email me your fcf file to
ben@matrixmultimedia.co.uk

Hello Polanco
Here is the link to the update.
http://www.matrixmultimedia.com/softwar ... v3.2.2.msp
It appears that the information on the Flowcode download page may be incorrect. When did you last perform the upgrade.
The easiest way to tell which version you have is to run Flowcode and then goto Help -> About Flowcode.

Thank you.
My version is 3.2.2.40 and the patch in the link you sent me gives me an error: Windows instaler service can't perform the update...ensure the version of your software is the correct.
What version must i install first to run this patch?

Hello Polanco
Sorry about that. Here is the link to the full install.

You will have to perform an uninstall of your previous version of Flowcode before installing the latest version.
You will not have to re-enter your registration details so you can skip that step at the end of the installation.

Yes, that's wright. 3.2.2.40
Sorry Ben, but I installed my Flowcode in my 3 PCs to test this, and the SPI module doesn't work.
My OS is Windows XP Spanish version, and SP 2.
The same project but in Flowcode 3.1 works fine. Strange.
I still don't have V 3.3.

V3.3 has not been released yet. Ben is one of the privileged few to be using the latest version. I hope to release this sometime before the New Year.

Is this an issue in simulation only, or does the problem happen when the program is downloaded to the PICmicro as well?

Hi Steve, is my first time with SPI so I didnΒ΄t send it to a PIC yet.
It seems to be a simulation since RS232 workes fine in both simulation and real life.
Plan B:
Can you send me a simple projet working and see what happens in my Flowcode?
