TinyLily / Re: USB board getting super hot
« Last post by Ben Rose on March 18, 2019, 11:32:46 AM »
I'm not sure what happened, but it sounds like you should set that particular board aside! The board is damaged if it's hot enough to smell bad. Was it maybe plugged into the processor board the wrong way? Either way, please contact info@tinycircuits.com so we can try to figure out what happened and replace your board.

Thanks,

Hi- we've used the HX711 with a TinyDuino before. SparkFun has a great basic breakout with a very good tutorial: https://www.sparkfun.com/products/13879 Their code can be used with any Arduino including TinyDuino, and you should just need to pick two open IO pins(maybe A0 and A1, since the Matrix board uses 2 through 9). These could be connected through one of our proto boards.

Thanks,
Ben

TinyDuino / Initial serial output is lost on new TinyZero
« Last post by PSch on March 14, 2019, 01:33:07 PM »
Hi,
I just started to play with my new Tinyzero (with the accelerometer) board (impressive to get 3 or even 4 (with the RTC) boards in one now!!!).
After updating the Board manager (to get the tinyzero board option) I got my code to work. However, I noticed that with my code (written for the old t board system) as well as with the linked example code from Github (https://github.com/TinyCircuits/TinyCircuits-TinyZero-ASM2021/tree/master/examples/TinyZero_BMA250), I do never get the initial serial output from the setup section (i.e. all the initialisation messages e.g. "Initializing BMA..." in the example code). (I changed the Serial.print to SerialUSB.print, but still no success...).
The output from the main section of the code is then displayed OK.

Cheers!

PS: Could you also add an example on how to use the RTC on the new Tinyzero board? Does this work with the same libraries as for the previous RTC shield?

Tiny Arcade / CHARGING/AUDIO ISSUES?
« Last post by davecobb on March 13, 2019, 12:53:12 PM »
I have an original Kickstarter unit that now seems to be having issues.

It works when plugged into USB, but doesn't seem to charge, even when left overnight. Also, no audio comes out of the speaker, no matter what level the volume knob is at.

Thoughts?

Hello all

tinyduino is my first experience with arduino

I am looking to connect a 3 wire load cell wired up with a half bridge and a hx711 amplifier to the tinyduino with a matrix led to display the load

I would appreciate any help when it comes to how to connect the hx711 to the tinyduino while also connecting the tinyduino matrix led as well as any recommendations/sample code for getting it up and running

Thanks in advance

General Discussion / Problem Initializing BMP280 Sensor after SD Card Insertion
« Last post by wendolw on March 01, 2019, 12:49:25 PM »
I am configuring the BMP280 pressure sensor for a science project using instructions provided at Rocket Altimeter Logger[tinycircuits.com]. The instructions are well-written, and provide a direct interface with the device. First, I tested the TinyShield USB using the "blinking" sample code. Then, I uploaded the actual code for the pressure sensor. Initially, this also was successful. However, the remaining instructions do not provide a link to a serial monitor to display data output. To address this issue, I ran the program in the Arduino Sketchbook (Arduino.cc) environment. I transferred the written code for the sensor and data logger (4 programs: TinyShield BarometricPressure, BMP280.CC, BMP280.h, Altimeter_DataLogger) to the Sketchbook to monitor its output on the Serial Monitor. The board and port designations were correct. I was able to obtain sequential output (time-temp-pressure) from the device, displayed on the serial monitor. However, when I attempted to load the SD card to download the data (turning off the device before inserting the SD card), the sensor stopped working. On the serial monitor, I received an error message, "BMP Init failed". It appears that running the code in the Arduino.cc environment is compromised when the SD card is introduced to download the data, leaving definitions of the BMP280, imprecise. Please provide general feedback, or a specific recommendation for, a) code correction for the data output interface, and/or b) how to secure a link to the serial monitor on the Rocket Altimeter Logger page. Thank you.
