Based on PIC monolithic integrated circuit’s SPWM control technology
Sunday, September 14th, 2008 at 19:33 | No commentsCategories: SCMShort Content: Introduction In electric power electronic installations and so on UPS, the control method is the core technologies. The early control method causes the output is the rectangular wave, the harmonic content is high, the filter are difficult. The SPWM technology has overcome these shortcomings well. At present the SPWM production method are many, compiles as follows. 1) uses the discrete component, uses the simulation, the digital blending electric circuit to produce the SPWM wave. This ... -
PIC monolithic integrated circuit pin interrupt routine design tactics
Friday, September 12th, 2008 at 00:55 | No commentsCategories: SCMShort Content: 1 summary All middle-grade series PIC monolithic integrated circuit, the PORTB port highest 4 pins (RB7~RB4) when supposes for the input pattern, when the input level from high to low or from low to high changes, may let the monolithic integrated circuit have the interrupt. This is the usually called pin change of state interrupt. When design pin interrupt routine, three need special attention place. First, before eliminating P0RTB interrupts flag bit RBIF, must arrange one essentially, as the ... -
