1. PiC Ready2 Manual All Mikroelektronika s development systems feature a large number of peripheral modules expanding microcontroller s range of application and making the process of program testing easier In addition to these modules it is also possible to use numerous additional modules linked to the development system through the I O port connectors Some of these additional modules can operate as stand alone devices without being connected to the microcontroller ElMikroHektronika SOFTWARE AND HARDWARE SOLUTIONS FOR EMBEDDED WORLD waking ik siw ple PIC Ready2 Additional Board The P C Ready2 additional board enables a hex code to be quickly and easily loaded into PIC microcontrollers by using the PICFlash programmer or the bootloader software The additional board is supplied with two sockets for microcontrollers in DIP18 package 2x5 connectors connected to the microcontroller pins pads srew terminal for power supply USB connector and reset button Key features Programming microcontrollers with the bootloader software and PICflash programmer Power supply voltage in the range between 8 and 16V AC DC and Pads PROTO board DEVELOPMENT TOOL PIC Readu2 BY MIKROELEKTRONIKA Y REMOVE ON 4 PO Figure 1 2 additional board How to connect the board Power supply voltage from 8 to 16V AC DC is supplied to the additional board via the screw2.

3. used for the UART communication The position of these switches depends on the arrangement of the microcontroller pins connected to the UART module In order to perform programming with the bootloader software it is necessary to use microcontroller which already has the bootloader hex code loaded into it You can load the bootloader hex into the microcotroller using the PICFlash programmer This should be done only once and after that you can program your microcontroller with the bootloader software via the USB connector Some microcontrollers get the bootloader hex file in the Example folder along with other examples for PIC compilers for example C Program Files Mikroelektronika mikroC PRO for PIC Examples Other Bootloader When the hex code loading is complete it is necessary to reset the microcontroller by pressing the Reset button MikroElektronika In addition to the hex code loading with the bootloader software the USB connector supplied on the additional board can also be used to enable connection between the microcontroller and other devices that use serial UART communication When using the USB connector for the UART communication it is necessary to turn on the appropriate switches on the DIP switch SW1 2x5 connectors placed on the right side of the additional board enable easy access to the microcontroller pins Each connector is linked to one microcontroller port PORTA and PORTB 7227 Pm 2212
