Arduino Nano PI Main Discussion

[Rzouga]

Thank you Marty, unfortunately none of these are available except the bc517 so I will give it a try. For the power up I wanted to see what you guys experimented and if someone tried one of those portable usb powerbanks to power up a PI metal detector.

reference table, look on right side of it

for info, this weekend, i tested the modification seen with carl, that of post 416 - 417. the result is very good. the nano with V SAT. on a very steep and very salty beach, on the dry / wet border, there is almost no buzz. Thank you carl for the help!

I?m a newbie and ordered a Nano Every. Was it the wrong thing - I should have gotten a nano 3.0 instead? Doesn?t like loading the sketch. (But I don?t really know what I?m doing) Will load a blink demo sketch though and blink.

I haven't tried a Nano Every, but it's supposed to be a pin-equivalent substitute for the Nano, and the code should still work.

Here is a clip illustrating the differences between the two boards:

Thank you guys for your answers, PCB arrived from JLCPCB yesterday, I will be very busy the coming couple of weeks and then I'll order the rest of the components and start the fun

I had installed the Every using that video as a reference. I can run the blink sketch and change timing if I want. But the nanopi sketch fails to run - I do see the listing in the editor ok. Im sending it back and ordered a 3.0 oldschool real deal card. The future is supposed to be the Every though.

What is happening when you try to upload the Sketch?

OK - here's a possible solution ->

I note that the Nano Every has a clock frequency of 20MHz, whereas the standard Nano is 16MHz. In that case you will need to change line 14 in the sketch from:
const float clockCycle = 62.5E-9; // Time for one clock cycle (1/16MHz)
to:
const float clockCycle = 50.0E-9; // Time for one clock cycle (1/20MHz)

Otherwise all the timings will be screwed up.

I Googled it and the Every has way different timers. Several people having the same issue with no fix. Don’t buy one for this project.

I had loaded that (megaAVR) from the start. I had watched the video noted above where he said to do it.

Dear folks,

I also ordered the Nano book and build the power supply accordingly (fig 2-2) but with a LT1054 instead. The voltage between TP1 and TP3 measures however -12V. The Arduino has the programm running. There are no other parts connected. Should I change some capacitors or add components like a 79L05 to get -5V?

Thanks in advance,

Richard

What voltage do you have at pin 8 of the LT1054?
