Yet another temperature controller
G'day Paul, I've used these temperature sensors before and with offsetting and amplifying the signal you could easily get stable readings of the mentioned 0.1°C resolution. There...

Division by 3
G'day Angelu, I thought I would add the Assembler code to show how to simplify the multiplication and avoid a 32 bit result. It's been a while since I've coded and I haven't...

ADC values variation
G'day Pedro, Can you describe the infra red light that you want to measure? Are you providing the light source? If so then you could look into modulating the light soruce...

ADC's losing calibration again and again
For my two cents worth I think that the power consumption in the resistor divider is significant. At 25V the current is 20mA. Then the 1k resistor will be consuming 0.4W which...

I am building a 450V supply from 12V
G'day paramx55, I've looked at a similar CDI ignition and have made a hobby level power supply for my testing purposes. In short it is a 12V to 400V boost converter with 80W peak...

Baswic circuit to display temprature!
G'day atroce, I'm doing the same thing (with temp & pressure) so I had a look at your code and it simulates fine. I've only quickly checked the A/D registers but they seem ok...

the division result to LCD 16x2
G'day Franfray, A simple way is to use the divide function you already have. Assuming you want to display 1 byte then the range is 0-255. So divide the number to be displayed by...
