#136539 - hmmm.... Responding to: ???'s previous message |
i dont understand tho...if i hit reset and P1.1 is high, and in addition i have the following code fragment:
-------------------------- sbit out = P1^1; void main(void) { while(1) out = 1; } -------------------------- then why would the buzzer stop buzzing after a about 1 second? right now it seems to work fine the way i have it (using the NPN)... |
