Abstract

This work has completed the communication between the CC2530 coordinator and the child CC2530 nodes based on the Zigbee protocol. In this system, the object is detected by the CC2530 ultrasonic nodes. The distance is calculated and the message is formed. The message is sent to the coordinator by IIC bus which includes the control instruction. The coordinator receives the control information and will issue a command to control alcohol sensor to control the motor interface. The system can control the motor forward, backward and keep the DC motor still. The system can be widely used in agriculture and other fields. DOI: http://dx.doi.org/10.11591/telkomnika.v11i1.1919

Abstract

This work show how to port μCOS-II kernel and to build the ARM cortex-m3 hardware platform. This program researches how to drive the basic external devices. This paper gives a detailed discussion that the driver programs of the underlying hardware is how to be expanded into the uC/OS_II to process the tasks from the platform. The applications can make the STM32 processor work normally by calling the functions of transplanted uC / OS_II. The system is an actual embedded real-time multi-task operating system. The speed of processing multi-tasks is faster than conventional micro-controller’s. Because this system can run the highest priority task without return to the while loop. At last, this paper gives the structure of the main framework, the code of the tasks. DOI: http://dx.doi.org/10.11591/telkomnika.v11i7.2839
