inDART-STX is a powerful entry-level tool for STMicroelectronics ST FIVE- and ST7-based systems. inDART-STX takes advantage of the ISP (In-System Programming) feature to program the FLASH memory of the target microcontrollers. inDART-STX seamlessly integrates into your favorite development environment: STMicroelectronics STVD7 and Metrowerks CodeWarrior for ST7 (if you are working with ST7 devices) or STMicroelectronics Visual FIVE and Raisonance RKit-ST5 (if you are working with FIVE devices). STVD7, Visual FIVE and RKit-ST5 are conveniently included with inDART-STX, thus providing you with everything you need to quick-start your projects: you can write, compile, download (program), in-circuit emulate and debug your code right out of the box. The debugger/programmer unit is connected to the host PC through a USB port, while the 10-pin connector of the product fits into the targets ISP connector. On Design Kit packages, a full-featured experiment board for a specific microcontroller is also included.
Contrariwise to traditional in-circuit emulation (where the target application is executed and emulated inside the emulator), inDART-STX uses the very same target microcontroller to carry on in-circuit execution. This means that all microcontrollers peripherals (timers, A/D converters, I/O pins, etc.) are not reconstructed or simulated by an external device, but are the very same target microcontrollers peripherals. Moreover, the inDART-STX debugging approach ensures that the target microcontrollers electrical characteristics (pull-ups, low-voltage operations, I/O thresholds, etc.) are 100% guaranteed.
The ISP feature allows you to update the content of the FLASH program memory while the chip is still plugged in the application board. ISP programming uses a serial protocol to interface a programming tool like inDART-STX. The ISP interface can be implemented with a minumum number of added components and board area impact. inDART-STX uses the standard, 10-pin ISP connector to program and in-circuit emulate the target device. The diagrams below show typical ISP interfaces for both ST FIVE and ST7 devices.

On Design Kit packages, a full-featured, microcontroller-specific evaluation board is also included. Evaluation boards feature a socketed microcontroller, DIP-switches, jumpers, LEDs, push-buttons, potentiometers, prototyping area and an ISP connector and can be used for evaluation/experiments in the absence of a target application board.
