ADC quits working program continues to run
This is the main loop, I use an Resistor network and sink current through 4 pins to drop the voltage to about 1.8V, all pins changed to input blocks current and voltage from...

Routing Traces Under SOIC8 Ok?
Thank's I am almost finished with with detaling all the parts, sizes etc , when I am ready to make boards I will shoot yu a copy to have a look at.

Capacitance/ Breadboard VS soldered board your experiance
From the original question about the capacitance of the fet gate, I have modified the circuit with the help of those posting. I hev gone from 4 levels of output to 16 levels, I...

Capacitance/ Breadboard VS soldered board your experiance
I think this could do the trick for 15 levels between 1 and 2 volts I can change resistors to make it whatever high low I need. I have 7.2mA through the 132ohm resistor at 1.01V...

Capacitance/ Breadboard VS soldered board your experiance
I have PM'ed the schematic but I may have missed one of you if you did not get it let me know.

Capacitance/ Breadboard VS soldered board your experiance
Sorry Scott, I should have made it more clear. You are correct on everything except I am measuring across the RESISTOR, as the probe pin drains the gate affecting the readings....

Capacitance/ Breadboard VS soldered board your experiance
Hi Scott, I will be a happy man when I can look at a plot like the one above and see what you see. Perhaps I should read some books on reading scope output. Yes, I am switching...

Capacitance/ Breadboard VS soldered board your experiance
Quote:100,000pF capacitor That's what I thought, a picture here shows the first peak with the 470k resistor and the second with 2 470k's in series (I added onr to the board) It...

AVR ADC Aquisition time
From 13 to 260us See page 198 starting with... By default, the successive approximation circuitry requires an input clock frequency between 50 kHz and 200 kHz to get maximum...

CrispAVR-USB from chip45.com
Yes I like programming in assembler as it helps me narrow down my thought process and I think my ADD kicks in and I get confused writing in C or Basic (Bascom) because I write too...
