Hi,
I have a question about voltage dips in flash drive, if the voltage of an operating flash drive drops from 5V to 3V or 0V in a short time, eg: miliseconds/microseconds, is there any possibility that the operating flash drive will disconnect or lose data during data transfer with pc?
Thank you.

pic16f877a 5v lm35
Hi,
I still have some question about the calculation of LM35.
Take an example, if the output of LM35 is 0.28V, and the configuration bit of ADC is as above (ADCON1= %10001110) with AN0 as the analog input and Vref+ (Vdd = 5V) Vref- (Vss = 0V), then how does the PIC converts...

Finally I got the result that I want! hehe
I tested the circuit on breadboard and the simple program of showing temperature reading was working!
Suspected problem with pull-up resistor in programmer caused the error of ADC reading.
Now I can move further to...
pic con lm35
Hi,
I just tried the code, finally I get some decimal point. The results is 04.8 deg C, although the result after I removed the output of LM35DZ from PIC is 0.28V (28 deg C).
I'll try to build the hardware on breadboard and test later. See if I can get the result.
Thanks for the...
fire alarm circuit using lm35
Thanks leemarrow.
I don't have any schematic for this as I only connect the output of LM35DZ direct to the AN0 of the programmer board with PIC16F877 attached. I want to do the basic thing by showing the temperature on LCD before I proceed to the harder part.
So...
lm35 with pic16f877a circuit diagram
Thanks for the reply leemarrow.
Can you make it simple for me? Because after that I'll be using one reading of LM35DZ(Let's say Temp1) to compare with one or more reading of the others LM35DZ(Mayb Temp2, Temp3 and so on) instead of using reference voltage...
lm35dz circuit pic
Hi, I'm new here and new to PICBasic as well.
I'm working on a project which I was required to use several temperature sensors (LM35DZ) to measure the temperature inside each room and another temperature sensor to measure the atmospheric temperature. When there is huge...
