Development Board, it is first necessary to have a 1. Plug In Module PIM installed on the male headers U1. A. A PIM is always required, as the microcontroller U1. PIM area is part of the PICkit On Board programmerdebugger circuit, and is therefore not intended for running application related code. A list of available 1. PIMs which are compatible with the Explorer 1. Explorer 1. 6 Development Board can be found at http www. To begin development and programming the PIM microcontroller and using the hardware of the Explorer 1. Development board, it is recommended to obtain the MPLAB Integrated Development Environment IDE and a suitable C compiler supporting your desired target PIM microcontroller. MPLAB X IDE and MPLAB C compilers can be found at http www. Microchip provides a wide variety of free example firmware projects and libraries, which are compatible with the Explorer 1. Development Board. Some initial out of box demo projects are available from http www. Explorer. 16. 32. These demos exercise and demonstrate the basic functionality of the Explorer 1. Development Board and the microcontroller e. ADC data to the LCD module. Details on the usage of the example projects can be found in the documentation accompanying the projects. Application and microcontroller peripheral interface code can be generated using the MPLAB Code Configurator MCC http www. Additional reference projectslibraries compatible with the Explorer 1. Development Board can be found in the Microchip Libraries for Applications MLA and Harmony packages http www. Harmony. Tips for Reading the Schematics. The net names of signals connecting to the PIM microcontroller headers U1. A follow a naming convention where each net except power and ground is prefixed with Pxx where xx is a number 1 1. The Pxx number corresponds with the U1. A male PIM header pin number associated with the net. Nets that are also connected to one or more dedicated hardware features on the Explorer 1. Development Board have net names with underscores and suffixes denoting their associated features. For example, the net P2. TEMP is the electrical signal attached to the U1. A male PIM header pin 2. TC1. 04. 7A temperature sensor U4 on the Explorer 1. Development Board. Similarly, the net P9. S5LED1. 0 represents the signal attached to U1. A male PIM header pin 9. S5, as well as LED D1. Explorer 1. 63. 2 Development Board. Java Access Jdbc Driver Download Oracle 11G For Mac. It is important to note that the U1. A male PIM header pin numbers usually do NOT correspond 1 1 with the pin numbers of the microcontroller mounted on the PIM PCB. For example, the PIC2. FJ2. 56. GA7. 05 PIM MA2. TQFP 4. 8 microcontroller, which does not have enough total IO pins to connect to and control all 1. PIM pins independently especially in a 1 1 fashion. Therefore, the PIM PCB maps microcontroller pins to PIM header pins on a functional basis ex PIM pin 2. P2. 1TEMP is connected to an AD input channel pin RA1AN1 on the microcontroller, which is TQFP 4. We recommend you refer to both the PIM schematics as well as the Explorer 1. Development Board schematics when tracing signals between the microcontroller IO pins and the connected hardware. In addition to the above conventions, the signal names for dedicated signals connecting to the mikro. BUS interfaces end in A or B. For example, the net P1. SCKA connects to U1. A male PIM header pin 1. SPI interface SCK pin on the mikro. BUS interface A. Meanwhile, the P5. SCKB net connects to the U1. A PIM header pin 5. SPI interface SCK pin on the mikro. BUS interface B. The P5. SCL and P5. 6SDA nets are, however, associated with a shared I2. C bus that is connected to both mikro. BUS A and mikro. BUS B interfaces. Consequently, these special signals do not end in A or B, unlike the dedicated mikro.
