Introduction to MINI-32 Miniature and powerful development tool designed to work as stand alone device or as MCU card in DIP40 socket. MINI-32 is pre programmed with USB HID bootloader so it is not necessary to have external programmer. If there is need for external programmer (mikroProg) attach it to MINI-32 via pads marked with RB6 (PGC), RB7 (PGD) and MCLR. Key features 01 Connection Pads 02 USB MINI-B connector 03 32.
02 System Specification 10 power supply 01 03 3.3V via pads or 5V via USB 04 power consumption depends on MCU state (max current into 3.3V pad is 300mA) 05 board dimensions 50.8 x 17.78mm (2 x 0.7“) 06 07 08 weight ~9g (0.
1. Programming with mikroBootloader step 1 – Connecting MINI-32 You can program the microcontroller with bootloader which is pre programmed into the device by default. To transfer .hex file from a PC to MCU you need bootloader software (mikroBootloader USB HID) which can be downloaded from: http://www.mikroe.com/eng/downloads/get/1678/ mini32_bootloader_v200.zip 01 After software is downloaded unzip it to desired location and start mikroBootloader USB HID software.
step 2 – Browsing for .HEX file step 3 – Selecting .HEX file 01 01 02 Figure 1-2: Browse for HEX Figure 1-3: Selecting HEX 01 Click the ”Browse for HEX” button and from a pop-up window (Figure 1-3) 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 1-4: Begin uploading Figure 1-5: Progress bar 01 To start .HEX file bootloading click the ”Begin uploading” button. 01 You can monitor .
step 5 – Finish upload 01 Figure 1-6: Restarting MCU Figure 1-7: mikroBootloader ready for next job 01 Click the ”OK” button after uploading is finished and wait for 5 seconds. Board will automatically reset and your new program will execute.
