Yes, it might be a hardware issue. yes its a different pcb.
I am sure now that the logic analyser is reading and writing the correct values. It seems that the NRF is not being setup correctly for channel etc. The IRQ line is floating, but tying it high or low makes no difference. However, I can...
Hi,
Using a PIC18F26K40 to run a NRF24L01 over SPI. Works as expected.
Trying to use PIC16F18326 to run a NRF24L01 over SPI. Doesn't work.
I am using pretty much the same code as the 18F. It is generated by MCC. The main differences are the microcontroller, and the pins that are being mapped...
Hi,
I am looking at a MAX4910 audio switch

There is a copper pad underneath it. Should that be soldered to ground or somewhere else?
Hi,
I would like to make a guitar signal level, audio switching circuit. I was thinking a 4066 or 4053, but I don't know how these might degrade the signal. Are they ok, or are there some specifically designed ICs that are better. thanks
No job, just wondering. Can they be purchased with driver circuitry already included so that a DC voltage is all that is required.
freq range, hmmm how about between 25KHz and 40KHz. perhaps something powerful enough to be felt, if that's possible.
take this for example...
Are ultrasonic transducers available with built in circuitry so that only need a DC voltage is needed to operate it?
How do I consider safety/ear damage, when using one?
What would be the best way to have an ultrasonic output with variable frequency?
Why is it that when the frequency of of musical note is changed by electronic methods, it doesn't sound good? The further the note is changed the worse it sounds. Changes in lower notes are better than changes in higher notes.
For example, playing a note on a guitar sounds ok, and playing one...
clamping 5volts to 3.3 is ok. Just trying to stop a blow up rather than incorrect functioning.
Yes both effects will be working at the same time. that's the point of the circuit.
A user might use two 3.3volt units, two 5 volts units, or a 3.3 and 5 volt in any order.
why the change? because Klaus the forum administrator, in his infinite wisdom, issued a warning and combined the posts.
don't want to clamp 5v to 3.3. why not?
How can i do this?
I want a simple expression pedal splitter where one expression pedal can be used to control two effects units.
However, one effects unit uses 5volts and the other uses 3.3volts. I thought some Schottkey clipping diodes like in the schematic would do the trick, but it seems...
don't know why this has been moved. Situation is different. The previous circuits were one's I had designed that had nothing more in them than a direct connection to an A/D input and direct connections to the rail.
I don't know what is inside the effects units exactly. Though I have a...
Power supplies in parallel
what happens on the wiper when two power supplies are put in parallel across a pot.
The scenario is two guitar effects units each with an expression jack. The jack outputs 5volts and is supposed to go across a potentiometer and the wiper voltage is fed back to the...
Clearly obvious. So, the question is ......
- - - Updated - - -
The circuit is a uC, a digital pot that interfaces to an external 5 Volt source, schottky protection diodes on the pot, and a power-on LED. uC is rated for 2.3 - 5.5 volts. I will be running it on 3 x AA's.
The load, whatever the...
