Hi, I have used Keil to complete a ADuc836(8051 core) product development. Now I am looking at another product with RTOS, by searching "8051 Chips Supported By Keil", I find only very few choice is available. (1) Is anyone in the forum know how to use Keil and RTOS on 8051 ? Is any successful story ? (2) Take CMX-RTX as an example. CMX-RTX says every task takes 28 bytes RAM, 8051 only have 128 bytes, how many tasks can create ? (3) Take CMX-RTX as an example. We know Keil employ call tree to deal with function pointer, programmer has to manually tell Keil compiler the actually called function, If this is your code, you can do that, However, if function pointer used by CMX-RTX (actually it does)? How do I modify call tree for RTOS ? Do I have to do that ? Thanks Daniel
The problems I have seen with using an RTOS is that most that use them consider it an excuse not to care about timing (a valid thing when programs run under windows). It is absolutely true that someone that can write quality code for the '51 without a RTOS can use the '51 with a RTOS. Ever so many that "demand" a RTOS have no idea what it means to program a '51 they state "C is C, why should I care" which is about as obscene as any expression can be. Erik
