#190847 - Small Device C Compiler 'sdcc' (free)
Responding to: Razman Ramedan's previous message
Hi Razman

The Small Device C Compiler ('sdcc') is free, and includes the 8051 as a target. According to the wikipedia page, it was used by FreeRTOS to port their RTOS to an 8051 variant.

The wiki page only shows a message "Project web is currently offline pending the final migration of its data to our new datacenter.", but the top-level page is available on the Wayback Machine at, so you may be able to find documents there, and any other related pages that are missing. (The Wayback Machine last took a snapshot of the wiki page on Jan. 15th, at which date the above placeholder message was not present.)

I didn't see a C tutorial, but there is a Tutorials page (1) with links to other sites' tutorials, such as a LED-toggle exercise targeted at multiple 8051 dev boards (2): (1) (2)

Project web is currently offline pending the final migration of its data to our new datacenter.
