Embedded/dsPIC 썸네일형 리스트형 dsPIC Programming Notes - Debugging Startup Code Microchip dsPIC Programming Notes Microchip has provided very good documentation and tutorial on their website, you can get yourself started with the resources. Here I'd like to present a few notes from my experience of programming with MPLAB IDE and dsPIC30F family chips to save your time. 1. Startup Function If you use the Project Wizard in MPLAB to create a project, you need to supply a main .. 더보기 dsPIC CNC servo Project Open source Project Description This project was developed as an inexpensive way to drive small dc brushed motors as positioning servos for use on a desktop sized CNC machine. The board is interfaced to the PC through 2 pins of a parallel port. The drive signal on these pins is known as quadrature drive. The power stage consists of a power op amp driven in constant current mode. The internal PIC processor (.. 더보기 MPLab C30 printf 사용하기 write()함수를 오버라이딩. #include 추가하고 아래 write()함수를 추가해 주면 된다. int write(int handle, void *buffer, unsigned int len) { int i; for (i = len; i; --i) { char c = *(char*)buffer++; U1TXREG = c; while(!U1STAbits.TRMT); } return(len); } 그리고 PIC은 Heap영역을 따로 할당해 주어야 한다. MPLAB Project Builder Option에서 힙영역을 할당해 주면 된다. 물론 printf를 사용하면 20%정도 오버헤드가 걸린다. printf 사용하지 않았을 경우 section address length (PC units) length (.. 더보기 이전 1 다음
