ADC quits working program continues to run
Doing some testing on my little LED sound project. I have code that calls the ADC filters the result and gives me a number between 0 and 15. The code can not return greater than...

Routing Traces Under SOIC8 Ok?
Trying to lay out a surface mount board without Vias Is it ok to rout some traces under the chip or will that cause a problem. I realized now it is a bit tougher to layout surface...

Capacitance/ Breadboard VS soldered board your experiance
I use a 470k resistor to bleed current from a 0.1 capacitor that holds a hexfet gate (IRLL110) When I soldered up a board I had to go to 1meg resistor to keep the same curve. I...

CrispAVR-USB from chip45.com
I bought one of these things and it works however it came with no documentation and none is available on the web site as of yet. I was able to program a tiny13V but obviously 1.8...

Trouble with INT0 Wake up Chip Interrupt
I am testing out the power down sleep mode on the tiny13. The LED just blinks telling me the interrupt is firing but when I hold PinB0 High it just keeps blinking. It should stay...

Minimum mA sleep and chicken and egg
I have my little drum trigger almost done now. I just added the velocity input using the ADC with the output of the op amp to a 470PF cap through a diode and ot works perfect. I...
