The firmware is written in asm/asm30 and comes with a preconfigured MPLAB-project. The GUI is written in C#.

• open source
• small size
• doesn't need installation
• checks hex-file for code that would overwrite the bootloader
• checks hex-file for goto at 0x00
• possible to select any com-port and baudrate
• remembers your settings
• requires.net framework 2.0
• Can check for latest version

Firmware dsPIC30F
* Fixed incorrect flashsize of 50xx devices

2. Download firmware
Download the firmware to your device using your favorite programmer.

3. Prepare your application
You need to make sure there's a goto placed at location 0x00 in you application. In most cases your linker allready does this for you. To check if it does you can pick Progam Memory from the View-menu in MPLAB. It'll look something like this:

4. Download the application to the device

• Start the GUI
• Select the desired communication settings and pick your hex-file
• Press the download button
• Reset your device
• Wait until write completes and you're finished

Q: How do I get the bootloader into my device?
A: You need to use an ordinary pic programmer such as the ICD2 or any cheaper third party programmer.

Q: Why do I get "The hex-file contains code that will overwrite the bootloader"?
A: If your application is big enough it will reach the end of the flash program memory where the bootloader is stored. You need to decerease the size of your application.

Q: Why do I get "Hex-file contains more config locations than the device has"?
A: If you use export a hex-file from Mplab you might get this. Please use the outputted hex-fil from the linker or compiler.

Q: Will you add support for PIC32 devices?
A: Probably not, at the moment I don't know very much about the architecture
