Programming
The microcontroller can be programmed in two ways:
- Using USB HID mikroBootloader,
- Using external mikroProg™ for FT90x programmer.
Programming with mikroBootloader
You can program the microcontroller with a bootloader which is preprogrammed 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/mikromedia-4-ft90x
After the mikroBootloader software is downloaded, unzip it to desired location and start it.
step 1 – Connecting mikromedia plus for FT90x
To start, connect the USB cable, or if already connected press the Reset button on your mikromedia plus for FT90x. Click the Connect button within 5s to enter the bootloader mode, otherwise existing microcontroller program will execute.
step 2 – Browsing for .HEX file
Click the Browse for HEX button and from a pop-up window choose the .HEX file which will be uploaded to MCU memory.
step 3 – Selecting .HEX file
Select .HEX file using open dialog window.
Click the Open button.
step 4 – Uploading .HEX file
To start .HEX file bootloading click the Begin uploading button.
Progress bar enables you to monitor .HEX file uploading.
step 5 – Finish upload
Click OK button after the uploading process is finished. Press Reset button on mikromedia plus for FT90x board and wait for 5 seconds. Your program will run automatically.
Programming with mikroProg™ programmer
The microcontroller can be programmed with external mikroProg™ for FT90x programmer and mikroProg Suite™ for FT90x software. The external programmer is connected to the development system via 2x5 JTAG connector.
mikroProg™ is a fast USB 2.0 programmer with hardware debugger support. Outstanding performance, easy operation and elegant design are its key features.
mikroProg Suite™ for FT90x has an intuitive interface and programming technology. First, download the software from MikroElektronika's webpage.
After downloading, extract the package and double click the executable setup file, to start the installation.
Click the Detect MCU button in order to recognize the device ID. Click the Read button to read the entire microcontroller memory. You can click the Save button to save it to the target HEX file.
If you want to write the HEX file into the microcontroller, first make sure to load the target HEX file using the Load button. Then click the Write button to begin programming. Click the Erase button to clear the microcontroller memory.
