*** FREERTOS+TCP IS STILL IN THE LAB (mainly because the FTP and HTTP *** | |
*** demos have a dependency on FreeRTOS+FAT, which is only in the Labs *** | |
*** download): *** | |
*** *** | |
*** FreeRTOS+TCP is functional and has been used in commercial products *** | |
*** for some time. Be aware however that we are still refining its *** | |
*** design, the source code does not yet quite conform to the strict *** | |
*** coding and style standards mandated by Real Time Engineers ltd., and *** | |
*** the documentation and testing is not necessarily complete. *** | |
*** *** | |
*** PLEASE REPORT EXPERIENCES USING THE SUPPORT RESOURCES FOUND ON THE *** | |

*** the sole discretion of Real Time Engineers Ltd., be offered versions *** | |
