MikroElektronika
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.

PIC-Ready2 Additional Board
The
PIC-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).

How to connect the board?
Power supply voltage from 8 to 16V AC/DC is supplied to the additional board via the screw connector CN7. This voltage is necessary
when the microcontroller, to be placed in one of the socket on the additional board, is programmed with the
bootloader
software,
Figure 3. This power supply voltage is also necessary when the pads are used, i.e. when additional components are placed on the
board for the purpose of simulating the operation of some device. The
PICflash
programmer is connected via a 2x5 connector CN3
which is shorted with jumpers, Figure 1.
When the process of programming is performed with the
PICFlash
programmer, it is necessary to do the following:
1. remove jumpers from the 2x5 connector CN3 (PICFlash connector) provided on the additional board.
2. connect an IDC10 connector on the
PICFlash
programmer to a 2x5 connector on the additional board, Figure 2.
3. connect the
PICFlash
programmer to a PC using a USB cable, after which the process of loading .hex code into the microcontroller may start.
When this way of programming applies, no external power supply is needed as the board is powered by a PC through the
PICFlash
programmer.
How does the board operate?
There are two ways of loading a .hex code into the microcontroller to be placed on the additional board. These are with the
PICflash
programmer and the
bootloader
software via the microcontroller’s serial UART module. In the latter case it is necessary to turn on
the appropriate switches on the DIP switch SW1. The DIP switch SW1 is used to determine microcontroller pins to be 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.

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).

The
Bootloader
software is integrated in all Mikroelektronika’s compilers. It is used to load a .hex code into the microcontroller
that already has the Bootloader .hex code loaded. In order to open the
mikroBootloader
window, it is necessary to select the
mikroBootloader
option from the
Tools
menu within the compiler’s main window. The first thing you should do after that is to select the
port to be used for connecting the additional board to a PC. One click on the
Setup Port
button causes a window with options such as
port selection, baud rate selection etc. to be open, Figure 6. Close the
Setup Port
window and click on the
Connect
button within the
mikroBootloader
window in order to establish connection between the Bootloader software and the
PIC-Ready2
additional board. To
break this connection, click on the
Disconnect
button. Use the
Open HEX file
button in order to select a .hex file to be loaded into the
microcontroller provided on the additional board. One click on the
Start bootloader
button will start up the process of .hex file loading.
This process can be ceased at any time by clicking on the
Stop bootloader
button.

bootloaders
provided with Mikroelektronika’s compilers, it is set to 9600bps
