Hello,
We are working on 8051 project and using Keil PK51 version 8.05; M/C is P89C52X2BN on 11.0592 Crystal.
1. If a large function is called from task A , and if the same function is called by task B while the function execution is not yet completed by task A, what will the controller do? Will it skip the function for a while / it calls the function / it treats it as reentrant? I am not taking any semaphore style measures for the function calling. I am facing some data corruption problems in my system. What should I do?
2. I need an example program on using Timer 2 interrupt alongwith the initialization of its related registers, if I need timer 2 in auto-reload mode in up-counting timer style. I had used all the related registers and initialized the timer, but it is not functioning.
Please advise
