No Spyware, No Adware

We hate spyware as much as you do. The Lite Edition of the Proton Development Suite does not, and never will include any spyware or adware of any form. Ever.

Features

Of course, because it's a Lite Edition, there are some limitations over the Full Edition — The Lite Edition supports the following devices:

12C508
The 8-pin, 12-bit 12C508 device is arguably the best-selling microcontroller of all-time, but has now been superceded by the 14-bit 12Fxxx range.
12F675
The 8-pin, 14-bit 12F675 is one of the new breed of PICmicros® that incorporates advantages such as ADC, comparators, on-chip EEPROM and of course Flash re-programmability.
16F628A
The 18-pin, 14-bit 16F628A is the sucessor to the ever popular, but now very outdated, 16F84 device. The 16F628A offers 2KBytes of code space, 128Bytes of RAM, on-chip EEPROM, comparators, USART and hardware PWM.
16F877
The 40-pin, 14-bit 16F877 is the Rolls-Royce of the 14-bit core devices and contains 8KBytes of code space, 368Bytes of RAM, 256Bytes of on-chip EEPROM and more on-chip features than you can shake a stick at - such a USART, HPWM, etc, and is the obvious choice for any new design.

The Lite Edition also has a restriction of 50 lines of valid BASIC code. This does not include; comments, lines containing only a label, or empty lines. This, we hope, should be enough to give you a feel of just how powerful the Development Suite really is!

Because of the 50 line limit, the INCLUDE directive has also been disabled.

The choice of crystal frequencies is also limited to 4MHz and 20MHz, as opposed to 3.58MHz, 4MHz, 8MHz, 10MHz, 12MHz, 14.32MHz, 16MHz, 20MHz, 24MHz, 32MHz and 40MHz available with the Full Retail version of the Proton Development Suite.

The Lite Edition download also contains the full Proton Development Suite's manual in PDF format.
