This article is about the use of an 8-bit PIC family of PIC microcontrollers PIC18F458 and PIC16F877 which are RISC type microcontrollers like AVR family microcontrollers and we have published a book on PIC using BASIC language (or order from Shoppee). This article, will be in C language and the board used as shown in Figures 1 and 2, but for the laboratory of the Faculty of Information Technology Phetchaburi Rajabhat University, choose a board for learning in the course of computer architecture as shown in Figure 2, and use a set of chip programs as shown in Figure 3. Article part 1 (Board CP-PIC V3/458 or CP-PIC V3/877), is an introduction to the features of the microcontroller and appearance of the laboratory test board. The use of the different parts of the PIC will be discussed in the next article.
