... C8051F930-DK 3.7. Keil µVision2 and µVision3 Silicon Laboratories Drivers As an alternative to the Silicon Laboratories IDE, the µVision debug driver allows the Keil µVision2 and µVision3 IDEs to communicate with Silicon Laboratories’ on-chip debug logic. In-system Flash memory programming integrated into the driver allows for rapid updating of target code. The µVision2 and µVision3 IDEs can be used to start and stop program execution, set breakpoints, check variables, inspect and modify memory contents, and single-step through programs running on the actual target hardware. For more information, refer to the µ ...
