Hi: I read a article named "RTX51 TINY: DIFFERENCE BETWEEN INTERVAL AND TIMEOUT" , but I still can not clarify the difference between interval and timeout . I hope that who can give me some simple and clarity examples to illustrate the difference between them. also who can give me a forum that discuss detailedly the RTX51 TINY.
That, of course, was because we needed to repeat ourselves out of desparation of the possibility that we were not hearing each other.
#include "rtx51tny.h" #include "REG935.H"
const unsigned char table[]={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80 ,0x40,0x20,0x10,0x08,0x04,0x02,0x01,0xFF,0x00};
int counter0; int counter1; int counter2; int counter3;
const unsigned char table[]={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80};
void LED0 (void) _task_ 0 { int i; os_create_task(1); os_create_task(2); while(1) {
for (i = 0; i < 15; i++) {
P1 = table[i]; os_wait(K_TMO,30,0);
} os_send_signal(1); os_wait(K_SIG,0,0); counter0++; } }
void LED1 (void) _task_ 1 { int i; while(1) { os_wait(K_SIG,0,0);
for (i = 0; i < 3; i++) { P1 = table[15];
os_wait(K_TMO,30,0);
P1 = table[16];
os_wait(K_TMO,30,0); } os_send_signal(2);
counter1++; } }
void LED2 (void) _task_ 2 { int i; while(1) { os_wait(K_SIG,0,0);
for (i = 0; i < 8; i++) { P1 = table[i] | table[i+7]; os_wait(K_TMO,30,0); }
os_send_signal(0); counter2++; } }
Here is my programe, you can emulate it by the KEIL. Opening the "peripheral"-->"I/O port"-->"P1".you will see the movement of the P1.
Now I want to use the os_wait(K_IVL,0,0) instead of the os_wait(K_TMO,0,0) to see the differnce between them.But I can not see the difference.So who can help me to modify the programe to show the difference clearly.
