Hi all, Wondering about teensy 3.6 ethernet lib status at this point. Earlier February comment was 2018. looking for an update if possible? I have an older T3.2 sketch I'd like to bring up. thanks in advance, tim

thanks for the quick response Markonian, I am using Paul's adapter and the recommended GPIO dance. swapped wiz850 out for a wiz820, page came right up. maybe it's just a bad adapter. agree? I'll look around and see if I have another 850. I've also been using wiz820 for over a year with...

Hi guys, I'm just coming back to a project now that used to work over ethernet with 820IO. However, after installing the new versions of IDE and teensyduino noted above does not put out a web page with 850IO. The serial monitor says the page is requested, but no page is served up in the...

Hi, I'm coming back to a teensy 3.2 sketch that worked fine on teensyduino 1.35, but no longer works in 1.36 regarding the adc conversions. Using arduino IDE 1.8.1. This is a data acquisition application using 12 adc inputs with external adc reference and pushes the conversions out to a web...

I read on another thread an issue with malloc sometimes corrupting the stack. Does the fix for this anomaly appear in 1.36?

Hey hyperdine, in your investigation did you by chance look critically at the reset signal? I was wondering that, if the flash was programmed but the reset signal was not robust, this possible "poor reset" might produce a symptom similar to a corrupted flash.

Thanks for the feedback. I'll continue to look as well and let you know if I have any breakthroughs. Happy hunting. Tim

Hyperdyne, did you ever figure out what was going on in your case? I seem to have a similar symptom that this morning seemed to point to flash corruption. I've been chasing it for months, initially pursuing different ethernet adapters and more recently additional filtering on the input of the...

I had mismatch teensyduino on the two machines. My bad.

Paul, I have been using two machines, one is the main one at it has teensyduino 1.35. However, I was doing builds on a different test only machine and it had teensyduino 1.30. I upgraded both arduino IDE and teensyduino on test machine, with public available 1.35. 850 works fine on both...

On my first setup, both 850s went into same socket. The change to 850 and rebuild/download was the sequence, got 0.0.0.0. Then back to 820, rebuild, worked fine. Same process on second setup, only changed 820 to 850 and IP address, rebuild/download and test. I'll upgrade tools and report...

Hey Paul, Thanks for taking the time. I bought two 850s, only tried one. Tried other on on that setup, same result. I have a second setup that has been running 820io for a while. Tried 850, recompiled, same 0.0.0.0 result. My 850s are yellow boards as well. I'm running teensyduino 1.35...

Yeah, I read that too. Added 2 sec delay, no joy.

Received and installed 850io adapters, upgraded from 820io; adapter only replacement. Oddly I get IP init of 0.0.0.0 with the same sketch. Added some increased delays, same result. Replaced with 820io again, works fine. Any ideas? Thanks,

I have the spare adapters, been using them for parallel testing at home. I haven't sped up this testing yet though. Thought that should be the next step. The app is a pull application, so there are no regular packets going out, only data collection. I did add a reinit to the Ethernet...

Paul, I have added code to periodically reinit the Ethernet but it didn't help. This code did the stuff you mention on the 820io web page. I was hoping that someone might comment on possible improvement of 850io over 820io. That is, if in a busy environment that the 820io might get...

I have a small teensy 3.2 application using 820io attached. Overall, this application gathers data from an off line solar and wind system, system voltage, several currents, turbine RPM and some other stuff. It runs a long time at my home with little network traffic. In the end...

Hi, I have a small application running on teensy and 820io that pushes out a webpage on a static IP address. I'm looking for an example sketch that creates a json output for ultimate import to a database. could anyone point me to such an example? thanks, tim

Could you post a pic of the wiz850io and teensy 3.6 together? Thanks, Tim

Thanks for the timeframe estimate Paul. It's always helpful to have a realistic expectation Have a good one Tim

I needed a web server

Thanks Paul, I didn't realize. Is there a reasonable lib I can use now on a preliminary basis? I thought I saw several benchmarked Ethernet examples for 3.6

pics below. the first two are in the big stack with the power stuff as well and an adapter board I made up. the third is teensy and eth alone, same symptom in both settings, pic also included. I can update this teensy fine by changing blink duty cycle, so that board alone is good. I am...

3,3v is on the board but no leds. I reduced cpu speed to 96Mhz, no help. Added 1 sec delay per following, no joy. would the SD card deselect affect this? pinMode(9, OUTPUT); digitalWrite(9, LOW); // reset the WIZ820io pinMode(10, OUTPUT); digitalWrite(10, HIGH); // de-select...

so, my ethernet init is working reliably now on teensy 3.2, but still have issue with 3.6. code attached. suggestions? apologies for not cutting down code size at this point. all I did was recompile for 3.6, no other changes. I get init ip of 255.255.255.255 instead of my fixed ip.

Hi Paul, that could be. how can I confirm I'm pulling 5200 stuff?

Hi, I'm using W5200 chip from Saelig on 820io adapter and teensy 3.2. oddly, my build only picks up w5100.h which it says is a cached selection. I am using teensyduino 1.35 and sort of expected the build to pick this up automatically. how can I get the build to pick up the correct lib?

Macaba, I did get this going, my issue was a very dumb one. While I did include Paul's code, I left off the last line which deasserts the reset line. so, of course the part could not init, as I was holding reset asserted. shame on me. thanks for your help, tim

Thanks guys, I'll give it a go Tim

Hi, Been using teensy 3.2 for a while, have always had intermittant ethernet init issues. An annoying issue is that 820io inits properly for a while, then doesn't, giving 0.0.0.0 instead of my fixed IP address. I have a couple 3.6 boards with newer ethernet, thought I would try that. With...

Thanks Paul. Happy holidays

the lib is setup to return a value only if there is an input frequency. sounds reasonable, but I'm trying to make a graph of RPM over time, so the lack of a response is troublesome. Is there an easy way to configure the lib to ensure I always get a reading, even if the reading is zero?

thanks KurtE, I was just wondering as to current status and if it had been validated. I have teensyduino v 1.31-beta2 installed and didn't see any reference to teensy 3.6. What version do you have installed? Your uncommented #define is identical to the one listed under teensy 3.1 in my...

a couple of questions. As background I have thus running and it works well on teensy 3.2. 1. Is FreqMeasure currently supported on teensy 3.6? 2. What teensy 3.6 pin is used for freq input? thanks, tim

pin3 works, I just missed it. thanks.

I also hooked the square wave to pin 10, verified it went to teensy. same result, that is sum = 0

Hi, Trying to get this to work but having trouble. I'm hoping to use pin 2 on teensy 3.2 (just next to the TX and RX pins), and have a good square wave input (see waveform pic attached, lower trace). The upper trace is a signal earlier in the circuit which is input to a comparator, then to...

wow, that is some skinny traces on the supply lines, not something I would build knowingly. Has anyone done power consumption measurements on the combo teensy 3.6 and ethernet? I'd like to see if I can move to a regulator smaller than that giant TO-220.

ok, pic attached. does this look right to you guys? I just want to make sure before applying power. The lowest board is an adapter I did that directly accepts teensy 3.2 to interface to arduino form factor. Been using it for a while now.

I've built a few of the ethernet boards from oshpark for teensy 3.6. I seem to recall reading that the pins need to be offset to connect to the teensy, but I cannot seem to now find that reference. so, can someone point me to a picture of both boards together? thanks, tim

sorry paul, thought the question was adequately generic to not need code. here is my current sketch.

I've added some "beep codes" on the led at various points in my sketch. it seems that things go awry when I disconnect the usb connector. is there some remedy for this? thanks, tim

Thanks Paul, encouraging on the flash reliability. I've fought similar issues over the years needing to do things a little differently with a cold boot vs debug mode, typically there is some guidance on where the sensitivities are. On the C++ front, I haven't overtly used any as I am so...

Oddly, sometimes I need to program teensy 3.2 more than once to get the program to "stick" through a power cycle. other times it works for a while then stops, but a reprogram regains expected functionality. usually the function stopping is with a power cycle, but not always. are these...

Tested this way as well, same 0.0.0.0 I think you're right, the wiz820io has seen better days. I was concerned if the USB port could provide enough power for this configuration, but guess it can. I have spare wiz and adapter boards, short a teensy just now. More in a week or so with an...

I substituted an old WRT54GL set for a DHCP server for the switch I was using, .didn't get anything in the serial window at all. moved back to the switch, get 0.0.0.0. unplugged ethernet cable, same. since my code is obviously running, could I be doing anything to other teensy pins that...

Thanks for checking Paul. Do you have a router on your system? I've found my router but not the power supply at this point to try it.

I'll try 2 things Teensy stack alone Add router Then report back Shortly Thanks guys Tim
