uCOS + LWIP limit TCP/IP to 60% of cpu power

Hello Greg,

MicroC-OS/II is a pre-emptive multi-tasking kernel. You can set the priority of the TCP and RX LWIP tasks to be lower than more important tasks. So, if you have a task which you want to run 40% of the time, leaving the remaining LWIP tasks to run during the remaining 60% time, simply create your higher priority task with a priority level above the LWIP tasks. If this higher priority 40% CPU consuming task would otherwise execute constantly, you can have that task give up CPU control by delaying for a fixed time period, thus allowing the MicroC-OS/II RTOS to schedule some time for the lower priority LWIP tasks to run.

Best regards,
