FreeRTOS and SMAC [Permalink]

I made SMAC compatible with FreeRTOS for the HCS08 chipset. There are two projects here:

1. The latest FreeRTOS for HCS08: FreeRTOS-3.2.4.hcs08.v3.zip
2. The new project to make SMAC work with FreeRTOS: FreeRTOS+SMAC-3.2.4.hcs08.v3.zip

The FreeRTOS + SMAC project needs to be at the same root level as the RTOS and SMAC projects. (You have to get SMAC 4.1a from Freescale.)

The sample project will use preemptive threading to send/receive a simple message between two EVBs [DIG536-2]. It should be the basis for any simple 802.15.4 project that would like to use preemptive multitasking.

It seems that FreeGeeks.net is pretty much dead, so I'm pointing the project files for FreeRTOS/HCS08 here.

Steps

1. Download and install FreeRTOS 3.2.4: FreeRTOS
2. Download this zip file: FreeRTOS-3.2.4-HCS08 Files.zip

3. Unpack it into a temporary directory.
4. Following the FreeRTOS directory structure, move the sub-folders into their correct places.
5. Open the RTOSDemo.mcp project in CW 3.1.
6. Deploy to a Freescale SARD or EVB.

FreeRTOS ported to HCS08 [Permalink]

I succeeded in providing a first (rough) port of FreeRTOS to the Freescale HCS08 8-bit MCUs. The CodeWarrior project file supports the the Freescale DIG536-2 (SARD) and the DIG528-2 (EVB) evaluation boards. These boards include an 802.15.4/Zigbee transceiver, so this is the basis for very low cost, pre-emptive multitasking wireless application.

The files are available at FreeGeeks. (Login to free account needed, then go to download-OSCookbook-HCS08.)
