| Abstract: | The design and implementation method of the serial communication software for personal computer(PC) and digital signal process(DSP) based on MODBUS protocol is presented,which is used in the intelligent temperature monitoring system.This system takes PC as the host computer and TMS320VC33 as the lower computer,and interruption mode to receive and transmit data.The experimental results show that the software can realize the data transmission between the host and lower computer reliably. |
