n Ready for AVR board Introductio Ready for AVR Board is the best solution for fast and simple development of various microcontroller applications. It comes with ATmega16 that is placed in DIP40B socket. It is preprogrammed with UART bootloader, so you don’t have to use external programmers to program the microcontroller. Board contains doublerow IDC10 headers for all available microcontroller ports. It also contains USB-UART module, prototyping area and a power supply circuit.
System Specification power supply Via AC/DC connector 7-23V AC or 9-32V DC power consumption 50mA in idle state (when on-board modules are off) board dimensions 14 x 8,2cm (5.51 x 3.23 inch) weight ~69g (0.

1. Power supply CN7 Ready for AVR board can be powered in two ways: over USB connection, or using external power sources, such as adapters, 7-23V AC 9-32V DC POWN POWP or laboratory power supplys. USB connection can provide up to 500mA of current, which is more than enough for evey on-board module and for operation of the microcontroller. If you decide to use external power supply, you can choose bewteen AC/DC adapter connector or power screw terminals .

er ad Programming with mikroBootlo step 1 – Connecting You can program the microcontroller with bootloader which is preprogrammed into the device by default. To transfer .hex file 01 Start mikroBootloader from a PC to MCU you need bootloader software (mikroBootloader USB HID) which can be downloaded from: 02 Click the Change Settings button. 03 In Setup window, select appropriate COM port. Click OK. http://www.mikroe.com/eng/downloads/get/1652/ mikrobootloader_atmega16_v100.
step 2 - Connecting step 3 - Browsing for .hex file 02 01 Figure 5-3: Browse for HEX 01 Press reset button on Ready board. 02 Click Connect button within 5s, otherwise existing microcontroller program will execute. Figure 5-4: Browse for HEX 01 Click on Browse for HEX button.
step 4 - Browsing for .hex file step 5 - uploading .hex file 01 01 02 Figure 5-5: Locating and Selecting .hex file 01 Select .hex file via open dialog window. 02 Click on Open button. Figure 5-6: Begin uploading 01 To start .hex file uploading click on Begin uploading button.
step 6 - Finish upload 01 Figure 5-7: Progress bar 01 You can monitor .hex file uploading via progress bar. 01 Figure 5-8: Browse for HEX 01 Click OK button. 02 Press Reset button on Ready board and wait for 5 seconds. Your program will execute automaticly.
Programing with AVRProg™ programmer Ready for AVR board contains IDC10 male headers for connecting AVRprog™ external USB 2.0 programmer. When connecting, make sure to orient the programmer connector so that first pins on both male and female header connectors align. Correct connector placement is shown on Figure 5-9.

6. USB-UART Fast on-board FTDI chip allows you to communicate with a PC or other UART devices using USB-UART connection. Female USB Type-B connector (CN9) is used for connecting the USB cable. RX and TX LEDs will indicate communication status. Before connecting the board with the PC, make sure to have the appropriate FTDI drivers installed on your operating system. Drivers can be found at following URL: http://www.ftdichip.com/Drivers/VCP.
7. Port headers DATA BUS Each microcontroller pin is available for futher connections through on-board connection headers. Pins are clearly marked which makes them easier to interface. IDC10 headers are compatible with over 70 additional boards from mikroElektronika, so you can easily add new features to the base Ready for AVR board.
8. General Purpose Area General Purpose Area allows you to expand your Ready for AVR board with additional functionalities, by placing your additional components into available soldering pads. Pads are arranged in standard 100mil distance form factor. There are 12 connected lines on both halfs of the breadboard area, and each line consists of 4 soldering pads. 8x8 matrix of unconnected sol de ring pads are located in the lower section.
9. Integrating with the casing Ready for AVR can easily be integrated into the specialized white plastic casing. This feature is very conveinent for turning the board into a final product. The white plastic casing contains inner and outter screw holes. Inner are used for attaching the board to the casing, and outter are used for connecting the top part of the casing, and enclosing the board.
