Programming with mikroBootloader Microcontroller is preprogrammed with USB HID Bootloader, which can be used to upload new device firmware. To transfer firmware .HEX file from a PC to MCU you need to use mikroBootloader USB HID application, which can be downloaded from: step 1 – Connecting mikromedia http://www.mikroe.com/downloads/get/1682/ mikrobootloader_pic18f87j50_v210.
step 2 – Browsing for .HEX file step 3 – Selecting .HEX file 01 01 02 Figure 3-3: Browse for HEX Figure 3-4: Selecting HEX 01 Click the Browse for HEX button and from a pop-up window (Figure 3.4) choose the .HEX file which will be uploaded to MCU memory. 01 Select .HEX file using open dialog window. 02 Click the Open button.
step 4 – Uploading .HEX file 01 01 Figure 3-5: Begin uploading Figure 3-6: Progress bar 01 In order to upload .HEX file click the Begin uploading button. 01 .HEX file uploading can be monitored via progress bar.
step 5 – Finish upload 01 Figure 3-7: Restarting MCU Figure 3-8: mikroBootloader ready for next job 01 Click the OK button after uploading is finished. The board will be automatically reset and after 5 seconds your new program will be executed.
Programing with mikroProg™ programmer Figure 3-9: Connecting mikroProg™ to mikromedia™ The microcontroller can be programmed with mikroProg™ programmer and mikroProg Suite™ for PIC® software. The mikroProg™ programmer is connected to the development system via the CN6 connector, Figure 3-9. mikroProg™ is a fast USB 2.0 programmer with mikroICD™ hardware In-Circuit Debugger.
mikroProg Suite™ for PIC® Software mikroProg™ programmer requires special programming software called mikroProg Suite™ for PIC®. This software is used for programming of ALL Microchip® microcontroller families, including PIC10®, PIC12®, PIC16®, PIC18®, dsPIC30/33®, PIC24® and PIC32®. Software has intuitive interface and SingleClick™ programming technology. Just by downloading the latest version of mikroProg Suite™ your programmer is ready to program new devices.
Programing with ICD2® or ICD3® programmer The microcontroller can be also programmed with ICD2® or ICD3® programmer. These programmers connects with mikromedia board via ICD2 CONNECTOR BOARD. Figure 3-11: Connecting ICD2® or ICD3® programmer In order to enable the ICD2® and ICD3® programmers to be connected to the development system, it is necessary to provide the appropriate connector such as the ICD2 CONNECTOR BOARD. This connector should be first soldered on the CN5 connector.
