ARMExpress Lite ARM-7 DIP Module
Description
ARMexpress modules bring high performance processing power to the DIP24 form factor.- perfect for small volume applications where intellignece has to be added to your project. Featuring 16 TTL compatible digital I/O's and an easy-to-use serial interface, you can be up and running in no time. The BASIC compiler is easy to learn, or use a pre-configured C compiler.

Programming
ARMbasic is a 32-bit BASIC compiler for ARM processors. It was started to create a portable, alternative to hardware debuggers, but has quickly grown into a powerful programmable controller tool, already including support for asynchronous serial, I2C, SPI, PWM, timer and counter operations. It is run on ARM CPUs such as that found in the ARMexpress PCB, which is pin compatable with other DIP24 modules. ARMbasic is simple to use, and runs totally on the ARMexpress or from the PC for the ARMmite, and both can programmed from a USB/Serial port. The target applications include control functions, so performance and a powerful set of hardware routines have been included. The language has a minimum of overhead when compared to larger general purpose languages. Aside from having a syntax the most compatible possible with MS-VisualBASIC and PBASIC, ARMbasic introduces several new features such as hardware specific routines, string support, limited pointers and many others.     Simplicity Many control applications can be accomplished in a very small program ARMbasic can be installed in minutes, and be solving your control problems just as quickly While BASIC is considered a simplistic language, ARMbasic with built-in hardware functions and the speed of compiled code can be a higher performance solution than many more complex languages As it is an incremental compiler, it has the feel of an interpreter. Its quick and easy to debug its programs. Why learn a new development system, you can either enter programs directly from the console or use any text editor that you are already familiar with. BASIC Compatability ARMbasic from Coridium is not a "new" BASIC language. It is not required of you to learn anything new if you are familiar with any Microsoft-BASIC variant. Even if you don't have knowledge of the BASIC language, its constructs are easy to learn and easy to use. ARMbasic is case-insensitive; scalar variables don't need to be dimensioned or declared before use; MAIN function is not required. Syntax follows much of that of Microsoft-Visual BASIC Most of the PBASIC IO functions have been added INPUT and OUTPUT control pin direction HIGH and LOW control pin output values I2C on any of the 15 pin pairs SPI using any group of 2/3 pins HWPWM on ARMmite/ARMweb Software PWM on any pin with 256 levels FREQOUT on any pin upto 50 KHz PULSIN and PULSOUT will measure or output a pulse SHIFTIN, SHIFTOUT can be used for SPI or MicroWire devices OWIN and OWOUT support one-wire devices SERIN, SEROUT can be used for low duty cycle asynchronous serial ports on any pin upto 115Kbaud RCTIME will measure a capacitive delay Support for 32-bit variables and Strings Integer: (32-bit math) String support Automatic type conversions Arrays Static arrays supported, up to 32KB in size on the ARMexpress, 4KB on the ARMmite Memory Limits All arrays, variables and strings are allocated from a 32KB space on the ARMexpress, 4KB on the ARMmite Code will include user programs, constant strings (used in expressions or PRINT), DATA constants, and a forward reference table on the ARMexpress when using the on-module compiler. The PC compiler will resolve all references so that table is not required. On the ARMexpress 48KB is available for user programs, and an additional 8KB is available for DATA constants and constant strings. 4KB of this space (overlays DATA area) can be written into Flash and functions as non-volatile memory. Note that Flash may be written a minimum of 100K times. On the ARMmite 11KB is available for user programs, and 1KB shared for DATA constants (256 max) and constant strings.
