N00b using mega48 ADC
Quote:I cannot use internal 1.1V as Vref because that will overflow the ADCH/L register. Sure you can. Put a resistor divider from VCC to a switched common. Scale the resistor...

reading values from lm35 using atmega 8
Try a twisted pair cable (2 twisted pairs). One pair would have your temperature Signal and Common. The second pair will have your VCC and Common. Put a small capacitor (0.1uF) as...

Attiny 44 PWM power transistor overheated
I would put an ohmmeter across your bulb(s) and measure the resistance. You will find that it is nearly a short. When driving the bulb with 12V, the bulb element will not heat up...

ADC TMP36 Problem
If you're interested in experiments, try this one on for size. Give integer math a try. Here's what we know. The TMP36 has a gain of 10mV/C with an offset voltage of 500mV. The...

best choice for new design
Are the 4 output compares for one 16 bit timer for your PWM ? If so, are you sure that you need 16 bit PWM resolution ? Since you mentioned that you need deadband control, we...

best choice for new design
Counting up your I/O it looks like you need a maximum of 31 I/O lines. 11 max for 8 bit LCD interface 4 A/D 4 PWM 4 GPIO 8 Switch I/O -------- 31 Total (max) An Atmel ATMEGA164...

digital oscilloscope for begginer
David brings up some good points. Think of your world divided up into two domains - analog and digital. In the analog world, you will be looking at analog signals that are output...

digital oscilloscope for begginer
If you have the money, I'd go with the DS1102E (100MHZ version). In no time at all, you will wish you had the extra bandwidth. Nice looking entry level scope. However, it only has...

1 - WIRE or 2 - WIRE, SPI ?
Nothing seems difficult once you understand it. You will need to study, practice,and gain confidence in what you do. This problem is no different. If you haven't already...
