| Not reading the datasheet for TC74 was the source of my errors. I am using TC74A0-5.0VCT but I was copying codes written for TC74A5-5.0VCT
Everything worked when I replaced i2c_start(); i2c_w ... |

| jspencer,
Sorry about the confusion. What I meant was that if I replace if(temp==-1) statement with if(temp>0) the buzzer still beeps. That problem has been fixed with PCM Programmer's code. ... |

| Asmallri, thank you for your help.
The problem I have now is that my Temp. Sensor reads -1 Celsius when room temperature is 75 F (23.8 Celsius). i.e. the buzzer beeps when (temp==-1) when I use the ... |

Forum: General CCS C Discussion Posted: Fri Sep 01, 2006 2:40 pm Subject: update |
| Unlike PICDEM 2 PLUS DEMO BOARD, I do not have pull-up resistors connected to PIN_D5 and PIN_D6 (FP_SDA and FP_SCL signal respectively)
Is this the source of my problem? |
