Benchmarks
This is a collection of tutorials that show how to get started with MCS-51 development using free tools and various evaluation boards. The tutorials include an LED Timer, which shows a binary counter that increments exactly once per second using the board LEDs and the MCS-51 timers, RS232 output using the UART (or a software UART where no hardware UART is available), and standard benchmarks for embedded systems (both Whetstone and Dhrystone; Coremark is not included due to its license, but can easily be ported using the Whetstone and Dhrystone tutorials as examples).
The author used a Debian GNU/Linux system, but the tutorials should work for other Linux distributions, *BSD or other Unices.
All tutorials use:
- The C compiler SDCC, version 3.5.0 or later to compile C programs for the MCS-51.
