52 RabbitCore RCM42005.2.7 Prototyping Board Function CallsThe functions described in this section are for use with the Prototyping Board features.The source code is in the Dynamic C LIB\RCM4xxx\RCM42xx.LIB library if you needto modify it for your own board design.NOTE: The analog input function calls are supported only by the RCM4200 model sincethe RCM4210 does not have an A/D converter.The sample programs in the Dynamic C SAMPLES\RCM4200 folder illustrate the use ofthe function calls.Other generic functions applicable to all devices based on Rabbit microprocessors aredescribed in the Dynamic C Function Reference Manual.5.2.7.1 Board InitializationbrdInitvoid brdInit(void);DESCRIPTIONCall this function at the beginning of your program. This function initializes ParallelPorts A through E for use with the Prototyping Board, and on the RCM4200 modelloads the stored calibration constants for the A/D converter. This function call is intendedfor demonstration purposes only, and can be modified for your applications.Summary of Initialization1. I/O port pins are configured for Prototyping Board operation.2. Unused configurable I/O are set as tied outputs.3. RS-232 is not enabled.4. LEDs are off.5. The slave port is disabled.RETURN VALUENone.
