+ | ==== Firmware releases ==== | ||
+ | |||
+ | The firmware code is heavily limited by the fact that it is limited my Microchip's licensing. This means, you may | ||
+ | only "use, modify, copy and distribute" the Microchip code "when embedded on a Microchip microcontroller [...]". | ||
+ | My code however, you are free to use under a four-clause BSD license, as long as you filter the Microchip | ||
+ | code away :P | ||
+ | |||
+ | Firmware version 1.0 is available! | ||
+ | * Want to hack, or add it to your own PIC-MINI-WEB?: {{:projects:tempdude-firmware-1.0.zip}} | ||
+ | * A known bug exists: the destination port number is fixed at 13579. Config does work for IP but not port. | ||
