Microchip PIM modules from the 8 bit PIC16Cxx family through to the 16bit dsPIC family and the new 32bit PIC32 family The PIM modules are available to order directly from the RS website and are separately listed in the catalogue from the RS EDP platform The adapter board is configured as a Command Module The Command Module in a system dictates whether the whole system is a 3 3V one or a 5 0V one The module has a link option which decides which of the two voltages is used within the system The Vcc CM line is set to this level by the link option on this adapter module This Vcc CM is used as a reference by the other modules such as the analogue module for example The daughter board remaps the 1 0 of the PIM module on to the backplane of the RS EDP system As the RS EDP system has a similar concept to the PIM module system from Microchip you will find most of the PIM modules will correctly map out to the RS EDP backplane During the development of this board several devices were chosen for trial fits to the RS EDP system These included the dsPIC33FJ256MC710 the dsPIC33FJ256GP710 and the PIC32Mx4xxFxxxL devices 2 Mapping 2 1 MCU Pin Allocation The MCU pins have been allocated to the backplane as follows dsPIC33FJ256MC710 RS EDP BASE BOARD Pin Name Comment Name 1 RG15 2 link options GPIO5 125 TX WS 2 link options GPIO9 125 RX WS 2 Vdd 3 PWM3H RE5 MOTORP2H
