I use teensy 3.2 with yun shield from dragino and CLI is provided in yun firmware. Hw signal from the yun is provided to trig prog pin. I also use arduino adapter shield from sparkfun for easy...

Hello,

I am user of teensy 3.2 and i have some install with yun shield (dragino).
I would like to change the way I linked the program signal to yun, because it is always triggered at power on....

I suspected first yun extension or power monitor chip with I2C interface. Thinking one of them blocking at initialisation step. I build similar setup to investigate more (the other is in other...

The teensy_loader_cli tool seems working correctly but the teensy program seems not running after that. Reboot the host does not help.
Disabling Yun Brigde feature in the sketch seems work around...

I have a remote teensy using Yun and find the following error:

Aug 2 15:21:19 dragino-16c830 kern.info kernel: [ 1590.970000] usb 1-1.3: USB disconnect, device number 44

Good tips. Thanks.
I used this initialisation :
Wire1.begin(I2C_MASTER, 0x0, I2C_PINS_29_30, I2C_PULLUP_INT, 100000); // address ignored for Master mode ; I did not add external pull up for...

Ok, I understand now I need to use i2c_t3 lib.
Can I found somewhere a "port" to Wire1 for Adafruit_INA219 lib?
I am starting the job.

Hello,

Using teensy 3.2 and trying to use SCL1/SDA1 (pins 29/30), I believed to find 29 and 30 in the part of code discussed. Anybody can me explain how it works for this second i2c bus? regards

I think I am in the same case as here : https://plus.google.com/116805762836780776401/posts/gUDqDhdLf5W

Hello,

Few month ago, I used the prop shield to drive an APA102 matrix.

I have not any more a prop shield and I use an other driver.

I do not remenber if I updated my fastled lib but the...

Hello,

You may be already see an other topic Understand-Prog-pin-in-Teensy3-1. This lastest concerns more the hardware interfacing.

Yun 2.4 seems more sensitive than 1.6. Problem appear with minimum of sensor, leds... not with basic configuration on the desk.

Hello,
I have an issue with my teensy, that seems blocked. Watchdog enabled and does not help.
I think it receive noise on the prog pin and then waiting for a sketch from teensy loader.
Is there a...

I finally use the reset pin (gpio20) without any resistor.
Just change /usr/bin/reset-mcu script to disable change of value for gpio20.
Use following script when you need to update your sketch :...

I see WS2812 seems more used here than APA102. Is the answer easier if I have WS2812 ?
Is one chip more reliable ?
Thanx

Hello,
I start a project using an APA102 8x32 led matrix +teensy and prop shield.
I would like to display some text.
I started with a library from adafruit and would like something faster.

Finally, I confirm my doubt concerning pin to use to lower prog pin. I use pin4_MOSI of the ICSP connector of the yun board (instead of the MISO like in the tutorial Dragino).

Also I updated the...

I suppose he used commands of this kind : echo 0 > /sys/class/gpio/gpio22/value with ssh connexion at yun board (see dragino script below).

I have the dragino yun shield v1.1.6 and I am afraid...

Hello,

Thanks all for your feedback.

Storbeck, I use load cell to trig notes for (musical) instruments on the floor.

May be I should present me in the appropriate section but I am not a spammer ;)
I am currently use load cell with complex hardware for finally only toggle inputs not for precise measurement, that...

Hello Storbeck, I am curious of your feedback. Can you give me some results of your experience? Regards,
