Salvo RTOS for HTPICC and MPLAB

[robban]

Hi!
I have arranged 6 tutorials.
Prerequisites: Salvo Pro RTOS v.3.2.3. Can be found elsewhere on this forum(search...). Install it as C:\Salvo. Replace all the files in the tut folder with the ones attached. Compiled for 16F877. What is actually happening is described in SalvoUserManual, appendix C. There are a number of interesting app.notes as well. Read them!
 
I've tried FreeRTOS as well but it's a mess... You can also try the CCS RTOS examples as well. The advantage there is that You don't have to connect any hardware to see what's happening. Just compile under MPLAB and choose MPLAB SIM for debugger. Choose Settings and select UART1 I/O tab. Pick Enable UART1 IO and choose Window for output. The new tab UART IO is now visible in the Output window. Now Run and watch! If You want to attach hardware to the CCS examples just replace the different OSTASK:s with LED blinking routines or whatever...

Forgot the attached files...

Hi robbin
have you compiled the microchip example of salvo found here
ww1.microchip.com/downloads/en/DeviceDoc/an11.pdf

i have tried but i think it has some errors
please upload the files if you did
and thanx for the tutorials

Hi mana11!
I think You supplied the wrong app.note. It doesn't contain any source code...
This app.note just explain how to optimize HT_PICC18 with Salvo.

Both HI-TECH PICC18 and MPLAB C18 report the same problem: Redefinition of OSCOMPILER and OSTARGET. I have to dig a little deeper into this before I can supply an answer....
If You installed the above mentioned compilers with preprocessor source code, have a look and compare to what salvocfg.h has to say.

Hi!
OK, after some digging I realize that this is a jungle. We can establish some facts: folder sysa belongs to HTPICC, folder syse belongs to MPLABC18 and sysf is the HTPIC18 folder. In each folder the salvocfg.h determines the behaviour of the supplied examples. With me so far? Now, since the HTPICC(sysa) folder can be compiled without too much fuzz, let's take a look at that: Nowhere in the sysa folder the file "salvocfg.h" is mentioned OSCOMPILER or OSTARGET! Nevertheless, the compiler is complaining about redefenition of these preprocessor defines. My best guess is that this Salvo edition is out of date, but what can we do since we don't pay for it. We've had it!! Some consolation for all of You: You can probably control a steel mill with just a PIC 16F877, at least when it comes to code space!! The Salvo method leaves very small footprint compared to others.
Any clever remarks?
