know thyself because what else is there to know


« on: May 14, 2011, 09:12:30 21:12 »

Dear Friends,

I spent whole my day to compile even a single small multitasking project with microchip c18 compiler & freertos. But result is nothing. I checked every documents on the web and tried to find the reasons why I receive error messages. But I think there will always be problems with freertos. Because it is not easy to use and there are many files to place in several directories.

god, my head is spinning.   

Any suggestions related to that kind of situation?

Best Regards, sughoi

Yes you need to program a "Hello World" as a first step, Find a simple  freertos example and follow it till you can understand it.
Make is simple and post any code, you get stuck on.

I already tried that but I think it need more configuration changes. Also I found ready compiled files and apply the same configuration as explained but result is the same. I am so confused.

I need an experienced person who made programming several times before.

I haven't seen that kind of difficult library files.

Demos targeting Microchip products
PIC32

PIC32 (MIPS M4K) MPLAB GCC
Port and demo application for the MIPS M4K based PIC32 from Microchip. The demo utilises the C32 compiler, MPLAB and the Explorer16 development board.
Microchip also have an application note showing how to integrate their libraries and stacks with FreeRTOS - with full source code being provided too.

PIC24

Microchip PIC24 and dsPIC® DSC MPLAB
Ports and demo applications for Microchip 16bit MCU's and DSC's. Both demos are targeted at the Explorer 16 evaluation board and use the MPLAB® C30 compiler.

PIC18
Please note that the segmented memory on the PIC18 makes it a less than ideal candidate for use with an RTOS.

Microchip PIC18 MPLAB
The demo is pre-configured to run on the 40 pin PICmicro prototyping board from Forest Electronic Developments, with a PIC18F452 microcontroller. This is a very low cost platform that has an in system programming capability. The MPLAB development tools are also utilised, comprising of the MPLAB IDE and the MPLAB C18 compiler.

Microchip PIC18 wizC
The port is created using the wizC Integrated Development Environment from Forest Electronic Developments. The port can also be used with the FED C-compiler, also from Forest Electronic Developments.
* do not under any circumstance use the Wizcoder/Wizdecoder found in sonsivri archives
Why not try to use the Explorer16 development board, in Proteus. easy to use as demos are already done for you.

You may also have a look a the Microchip Master's Conference 2009 (India).
There is a class on FreeRTOS and 16-bit and 32 PIC MCUs. That could help you.
Here is the abstract of that class:
"Free RTOS on Microchip’s 16/32-bit Microcontrollers     
Abstract   
Complex applications often demand the use of multiple software libraries and stacks. However, integrating those software elements together is often difficult. This class discusses the problems and demonstrates how a Real Time Operating System can be used to simplify the task. Using the Free RTOS kernel, attendees will focus on integrating the Graphics Library with other software elements and explore the optimizations that can be made. The presentation is complemented by practical application development and attendees will be challenged to develop a complex application that interoperates with software from their classmates. "

dear PCROBOTICS

Could you please upload the file to another site? The file is unavailable on 4shared. If you are able to upload please use rapidshare or hotfile etc.
