Re: Send Hex Data Serial Port

I have done a live demonstration of the whole process in my youtube - this one is for Widows machine but should apply for Linux and Raspberry Pi as well. The COM5 will get replaced with /dev/ttyUSB0 etc. Check this

Raspberry Pi Zero 3 Port USB Hub - No connector

I still have a lot of inventory of HubPiWi Blue - It can be used as a three port USB Hub ( The fourth port can be left unused as the newer Pi Zero comes with in built WIfi BT). All this for $5 https://ksr-ugc.imgix.net/assets/013/397/434/7350e6e06903d9c11ab5812c430d8bc7_original.png?w=680&fit=max&v=...

Re: Using USB instead of GPIO

Check my arduinopixed project - https://www.kickstarter.com/projects/17 ... or-pi-zero

The ArduinoPixed has a 4 Port USB hub and the 4th Port connects to ATMEGA328. You then have GPIOs and A/D off ATMEGA328. Control the GPIO through USB. Works on Pi Zero.

Re: Arduino and USB Hub on Pi Zero W

IIRC, the ATMEGA328 does not have USB, so perhaps the TxD/RxD pair and single line connections are reversed in the diagram. BTW, very nice device you've designed. Hi Paul, Good point. Fixed couple of more issues in the Block Diagram. Here is updated block diagram. https://image.ibb.co/iczrUR/Block_...

Looks interesting. A couple of questions: 1) Do we buy it directly from you or from the web site? (Or are they one and the same?) 2) It looks like it is actually $9 for the first one - $6 for additionals. Are there any other hidden fees?

You are likely know doing a clean shut down. Pulling the power chord is most likely the issue. For a hardware based solution, I have discussed it here - http://referencedesigner.com/blog/raspb ... tion/6662/

A Hardware solution will consist of a SuperCap, that will have enough juice to issue a shutdown command when pull chord is detected. See my latest blog about it here - http://referencedesigner.com/blog/raspb ... tion/6662/
