Arduino Nano PI Main Discussion

[MartinB]

Lots of useful parts, and at an inexpensive price.
I've saved that URL for future reference.

Thanks George
They are one of three local suppliers I use on a regular basis. Wherever possible I support local business because when they are gone, they are gone!

I worked out how to make a PDF in DT
the PRO-Q.

Hi 6666,
I tried one more of my batch and it worked well, I was going to do all 3 but I got side tracked building an LED clock kit. I am using version 1.8.12 of the IDE

Thanks , are there any brand names on the pcb ?
after much messing about my conclusion is my new nano is faulty in the 340 chip, I can read the 328 hex back out of the chip via icsp , so all may not be lost, but will have to order some more boards and cross fingers.
What seems to work for a nano with the 340 chip is if your IDE is 1.8.5 and up use the " 328p old boot loader" in processor,
if its under 1.8.5 use 328p, at least thats on a windows machine.

There are no brand names on the PCB. I am also using the 328P (regular) bootloader and that is using the IDE 1.8.12 along with Windows 10, so there certainly appears to be some other factors in the mix.

I'm using IDE 1.8.13 with Linux Mint.

Since you've obviously discovered a means of generating a PDF, I decided to give it another go. However, the print option does not allow me to print to a file. In the end I selected File > Preview and saved the schematic as a jpg image, and then viewed the image in a viewer and saved it as PDF. Unfortunately the result is not a clear as the one you created.

So... how did you do it?

I will try and do a write up tomorrow, its late here, it did take some manipulating.

In Windows 10:
File
Preview
Select X icon
Drag schematic onto sheet
Resize print scale to ensure schematic is captured in print area
Select Print
Select Microsoft print to PDF

Obviously I don't have "Microsoft Print to PDF" as an option in Linux, so you've made me go and use Windows 10.
Here's the PDF for the Arduino Nano PI Detector attached.
I'll also put this file in post #1.

I only recently ordered and received your Voodoo Project book which will be N/A for now because I just ordered your book for this project and really like the programmability concept and the fact that you're using a cheap Arduino board. I've always wondered why so many microcontroller-based project creators don't do the same, but it seems to be catching on. It simplifies everything including the PCB design and reduces or eliminates the need to do surface mount component soldering.

What sample ranges?

Got up early to do write up, Its seems you got it to work, there are a couple of ways to resize etc to make PDF, back to bed

It's all described in the book, but if you're referring to the main sample delay, you can actually figure out the answer to your question by looking at the Arduino software. With the current version, the delay can be adjusted from 10us to 72.5us. Obviously you can modify the code to do whatever you want.

Hi 6666 thanks for doing the pdf on the pro Q. In the past I've had to take pictures of the board and post them
now that you guys have done it I can figure it out by your posts and you guys wont have to look at bad pictures of my boards anymore
Cheers

All good GD
the trick with the pdf is to use the scale and print scale and drag to get the sch inside the square
you can also save the sch or pcb as a bitmap or jpg, on a win 10 machine
File
preview
adjust scale and print scale
click the + to drag the sch or pcb into square with mouse, then alter the scale and print scale to suit
save
save as bitmap or jpg
change to 300 DPI to get a good quality picture when zooming
name file
save
