alvieboy Posted January 30, 2016 Report Share Posted January 30, 2016 Finally at home.So I took some minutes to assemble one of my new wings - a very simple design for ESP8266, so you can use it with Papilio and ZPUino. Software and specialized hardware will be prepared in meantime. If we feel comfortable about this design we will share with you all details.For now, just a bunch of photos: Quote Link to comment Share on other sites More sharing options...
alvieboy Posted January 30, 2016 Author Report Share Posted January 30, 2016 And before any one asks, yes, I have not yet removed the resistor to the chip antenna. Quote Link to comment Share on other sites More sharing options...

alvieboy Posted January 31, 2016 Author Report Share Posted January 31, 2016 beautiful work, alvieboy let us know how it works out. Still to decide whether to use ESP as SPI master or SPI slave.... Quote Link to comment Share on other sites More sharing options...
Jack Gassett Posted February 1, 2016 Report Share Posted February 1, 2016 I can't wait to check it out! Jack. Quote Link to comment Share on other sites More sharing options...
Felix Posted February 2, 2016 Report Share Posted February 2, 2016 Still to decide whether to use ESP as SPI master or SPI slave.... what is the advantage/disadvantage to each? i have only ever used SPI master and that was for reading a tiny eeprom from a cable label cartridge Quote Link to comment Share on other sites More sharing options...
alvieboy Posted February 3, 2016 Author Report Share Posted February 3, 2016 The main difference between SPI master/slave relates to who triggers communication. Also slaves must make sure they can feed all data in a timed manner, otherwise you may get a buffer underflow.Note that my idea is to pass TCP/UDP packets to and from ZPUino - these can be quite large.

alvieboy Posted February 3, 2016 Author Report Share Posted February 3, 2016 Ok first tests done with new wing: ESP reset - PASSESP reset into programming mode - PASSESP reset into "normal" mode - PASSESP programming through ZPUino - PASSSPI data also seems to be there, so I think no issues will arise.

Felix Posted February 3, 2016 Report Share Posted February 3, 2016 the more i look at that ESP8266 the more i want to source a few to play with what kind of throughput are you expecting/seeing? Quote Link to comment Share on other sites More sharing options...
alvieboy Posted February 3, 2016 Author Report Share Posted February 3, 2016 Not necessarly worried about throughput, rather connectivity and reliability.But with an IO speed of 80MHz and a very efficient processor at 160MHz you can eventually do interesting things with it.The "biggest" data flow I ever used it for is actually OTA upgrade (using my own method). It's rather quick.What do you have in mind ? I can ship you one of these for a very interesting price, since they are prototypes as of now.
