| Abstract: | A two-processor control system was designed based on TMS320F240 and 80C196KC. TMS320F240 was used to sample welding parameters and to carry out, real-time control algorithm. 80C196KC was used to accomplish man-machine interaction, including keyboard, display and communication. Liquid crystal display was adopted as man-machine interface. The key of this system was the communication between DSP and MCU, dual port RAM was adopted. CPLD was used to complete digital pulse width modulation and logic controlling. All of these indicated that the system could realize fully digital controlling. |
