Hello everybody, I've been working for a long time with the RCM3700 in a somewhat complex application. Now I'm thinking on moving to the RCM6700, because I'm...

I can't offer advice on moving to another platform, but I can provide details on the serial flash of the RCM6700. The flash is shared between code and data,...

It seems when compiling for the RCM6700, by default the majority of the 32K BBRAM (20K) is allocated for FAT file system buffers - even if you don't use the...

It appears that you only have a single tcp/ip socket to work with. My suggestion is to create several sockets, perhaps 4-6, and use a switch statement to build...

Might want to move that ETH_MAXBUFS up a bit. I think the default is 10. Why are you moving it to 3? I'd remove that and test again....

Hi guys, In RCM3000, I'm using the frame drivers in gap mode for one serial port on an rs485 bus. However, it appears that transmission is always the priority....

If you are using RS485, there can only be one transmitter at a time as the line is half duplex. Most RS485 systems specify a master slave configuration with...

Hi Thanks for the feedback... Actually, the system design is a bit different from normal. The "master" control, which im working on (rcm3k), is supposed to be...

I have a reference system where this design works. The sensors are to check the bus if free, then wait for a predefined interval, recheck the bus again, then...

Hi Alex, The problem you will have is that in general, the RS485 drivers are destructive if you try to have 2 transmit at the same time. The drivers are ...

If you are using the 6750 or 6760, the best solution is to use _xalloc(&pAllocSize, 1, XALLOC_BB) for your persistent data. The full 1M of (BB) static RAM is...
