If you have control over (access to modify) the client, it would appear to make it easier to have a single TCP2UART and then use the content to identify the source and destination.

so the single client mentioned under 1) is opening multiple ports described under 3) eg a TCP2UART bridge with multiple TCP ports?

Just out of curiosity - if you only have a single client...

Since it appears that the Leo Bondar joystick controller is doing exactly what you need - why are you looking for an alternative?

This is what hlk-rm04 is supposed to do. it does not have DNS/DHCP, but you connect to a specific ssid and ip address and can configure the device as a WIFI <> UART bridge. And if the sticker is to...

Sorry if I was not clear. If all you want to do is to use esp8266 as an WIFI to UART bridge it is completely possible with the standard firmware. your link is referring to a webserver running on the...

If I understand you correctly you want this setup: Instrument <-serial-> Teensy 3.0 <-serial-> ESP8266. If all you need is to convert serial data to TCP or UDP packets to feed a separate web server...

Nice work. I have a few more of these coming in shortly. Not sure if CH_PD and GPIO0 is broken out, so this is helpful. Are you planning on customizing the firmware o just use it as is with Teensy?

So you have version 1 with only 3.3v, gnd, rx and tx pins active? do you mind sharing how you got this version to accept new firmware?

Based on a Google search it is likely a real person - just not a real product.. if it is possible to do a IP67 with wlan, bt and other wireless technology with 12 months battery life they should...

The hard reset works great - thanks for bringing this to the discussion. I am doing a hard reset in the setup() and got rid of the soft reset all together and it works great. Next step is to tackle...

This is a great write up and example. I solved most of my problems with a better power supply. I would not go with anything less that 500ma. I have a simple setup running T3: Touch input from ->...

Got a LM2596 voltage regulator of Ebay and using it it with an old laptop power supply. This seems to have resolved all the stability issues.

I have not tested it, but this guy seems to have created a pretty nice library. https://github.com/giannoug/ESP8266

My current power supply is supposed to 500mA. either it is not 500mA or the little thing draws more than 500mA in AP mode.

Hmm, I am getting random reboots in AP mode. My suspicion is my power source is is not sufficient. What are people using for power source for their projects? I am thinking about this one...

There appears to be so many different firmware (and maybe hardware) versions so a lot of the online examples does not work unless you have that specific version. I have hooked this up to a serial...

Thanks for the link, but I feel the same way as you - I am not going to add to the pile of boards I never use.

I realize there are some FCC complications, but i would love to see a T3.x with built-in wifi. I think there is a huge demand for some thing like this for IoT and other applications. Also support up...

Thanks. Looks like external power is needed - peaking at about 215mA. btw the firmware on mine appears to require CH_PD, RST, GPIO0 and GPIO2 needs to be pulled high to communicate over serial,...

I just got my first sample today. the firmware and documentation is pretty rough. I have not gotten it to do anything but responding with the firmware version. Can some one remind me the max mA i can...

Does anyone have a list of pin assignment between ENC28J60 and Teensy 3 using UIPEthernet?

Thanks!

Anyone successful in getting proximity sensing to work by modifying these constants? I just saw Touch board and conductive paint (http://www.bareconductive.com/) at Maker Faire and would love to do...

I was looking at the prototype of the adapter with room for a DB9. is the intention to support a single CAN bus at at time or all the data lines that normally is routed from OBDII to the DB9:

I just got a Zipit Z2. I installed OpenWRT and it is up and running and connected to my router. It should be USB host capable and does have I2C w/o any hardware changes, but I need to build a custom...

I would like to add a few items to the list:
- Haptic technology - "rumble" and other effects for home theater and games
- guitar effects

Not sure what cost implications WIFI would have, but I would take some @ $30 for projects around the the house.

I am trying to reuse steering wheel buttons in my car to control my iphone without dismantling anything. The traditional way to do this would be the CAN bus, but only the diagnostic bus is exposed on...

Agree. A lot of these spam attacks comes in bursts, so if people are willing to report multiple spam postings and waiting 60 seconds between each report, I am sure some of the more active...

If a price difference of $6 per board is determining which DEVELOPMENT board to to use, it is time for a different hobby or better business idea. :-)
From a hobby perspective i am very happy with...

The first I would try is to have the iRig powered from the microUSB while you are testing - some of these devices needs to have external power supply when used with iPod/iPhone while the iPad can...

I think your priorities are good. Just too many moving parts between T3 libraries and 1.5.2 beta IDE.
Time is much better spent on getting the USB host going ;-)

Paul, which SD card did you end up using?

I don't think anyone is suggesting anything different. Teensy will be recognized as a midi device. I believe the intent of the above breakout would add another

Teensy is great for midi as it is recognized directly as a midi device without any additional hardware. Some inspiration here. http://forum.djtechtools.com/showthread.php?t=21705 Most of these are...

Not sure what your hardware situation is, but unless you need more that 16 channels, you should be able to to run several control surfaces via a single MIDI. The teensy can act as a midi device. If...

This should do the trick and it comes with a DB9 and everything..

What do you have connected to the input pin? "poll" a is only called if there is a change to the pin value and ready is only called if poll is getting a value. If you feel confident pull should...

Since the sample code compiles fine for T3, there is really nothing we can help with unless you post your code and explain what your problem is. I do believe the interrupts are numbered after the...

Have you downloaded both Arduino http://arduino.cc/en/Main/Software and Teensyduino: http://www.pjrc.com/teensy/td_download.html

Nicely done! It would be great if you can/will share your code. A lot of people are struggling with strings and memory - especially then ones who are using an ardruino and not a teensy due to a...

Actually I wasn't thinking. the switch value has to be an enum, int or char and not a string, so it is a bit more complicated. If you post/PM the complete sketch I will take a look at it.

30ms is just an example. you need to check your specific situation to see what the scan time should be. You cannot have delays in our code if you want to use more than one trigger. You will often...

is there a way -tags or otherwise - to format attached code? If I copy and paste code in it is wrapping long lines and removing indention.

I am assuming you want velocity sensing since you are using piezos, so the digital read is no good as it is...digital eg on/off. if you don't want velocity sensing you can use a push button and a...

A lot of info here http://www.sparkfun.com/tutorials/330 , but based on your sample code, you have already been there :-) There are a couple of challenges. the Piezo signal will has a waweform and...
