TinyDuino / Re: Bluetooth BLE ST shield sketch loop locks up

« Last post by Ben Rose on January 10, 2019, 01:32:08 PM »

Looking through the code, I do see a delay being used in 'moveAllServos'- hard to say exactly how long the delay is(it looks like it's 0 if the servos don't change position but may be 10s or 100s of ms on large changes), but any blocking delay like that should be avoided to keep the main loop running frequently, especially variable delays. Let us know if removing that changes what you are seeing.

Thanks,
Ben

TinyDuino / Bluetooth BLE ST shield sketch loop locks up

« Last post by jakehenry41kc on January 09, 2019, 09:28:18 AM »

I have a TinyDuino project where I am trying to operate 2 of the micro EMAX servos offered on TinyCircuits website over BLE using a smartphone app that I've developed. My problem is that if I send servo pulses to the BLE shield too fast, the entire sketch loop ceases to function and I have to hard reset the TinyDuino processor to get the sketch to run again. This issue does not appear to be related to servo libraries or attempting to move the servos. When I comment out all servo functionality inside the main loop() function the sketch still locks up if I send integers to the BLE ST shield too fast.

I am simply connecting to the BLE shield via an Android app similar to nRF UART 2.0 (nordic semi) and sending servo pulse micro second values to the BLE shield as a string, once its received in the Arduino sketch, I convert it back to an integer and write that value to the servos. The minimum sized message I send to the BLE shield from the app would be a string "510" and the max value sent would be the string "2540". I have implemented a virtual joystick in the android app I am using and if i send pulse updates to the sketch too fast the BLE comms end up freezing the whole app into a non-recoverable state. If I lower the send interval to around 10 times/sec I don't experience sketch freezes as frequently but it is still and issue. I'd like to understand the root cause of this issue so I can implement an applicable solution where I can get the highest frequency servo pulse updates possible. I want to have smooth servo operation with little to no jittering. The lower the frequency I am restricted to the more jittering I experience in the servos for smaller pulse movements.

Please advise.

Thank you.

TinyDuino / Re: Compile error when linking TinyDuino with Rockblock

« Last post by IanBZa on January 08, 2019, 01:30:14 AM »

So I have found a solution:

----
This bug is specific to the 5.4.0-atmel3.6.1-arduino2 version of avr-gcc used by Arduino AVR Boards 1.6.22 and newer. It has been reported here:
https://github.com/arduino/ArduinoCore-avr/issues/39

A workaround is described in the link above.

Here's a less desirable, but possibly easier alternative workaround:

* Tools > Board > Boards Manager
* Wait for downloads to finish.
* When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21".
* Click "Install".
* Wait for installation to finish.
* Click "Close".

Due to a bug, this alternative workaround doesn't work with Arduino IDE 1.8.6, but it will work with any other version of the Arduino IDE.

If you have File > Preferences > Check for updates on startup checked, the Arduino IDE may occasionally notify you that a new version of Arduino AVR Boards is available, you'll need to refrain from updating back to the new Arduino AVR Boards version, otherwise you'll be back to seeing the segmentation fault error again.

------
The above is taken from: https://forum.arduino.cc/index.php?topic=574020.0 - so not my solution

General Discussion / Re: Tiny Screen

« Last post by HunterHykes on January 07, 2019, 01:29:43 PM »

Hi jmontoya,

Due to the hardware setup of the TinyScreen and TinyScreen+, it is not possible to read data from the registers in the Graphic Display Data RAM via SPI. The only way to read a specific pixel's color would rely on the use of a buffer array and reference the specific index corresponding to the desired coordinate.

However, if you just chose the pixel on the center of the screen to detect the color of the entire screen, here's something you could do.

uint16_t color;

if(x < 120){
     color = TS_8b_Yellow;   
}else{
     color = TS_8b_Red;   
}

display.drawRect(0, 0, 96, 64, TSRectangleFilled, color);

if (color != TS_8b_Yellow)
  display.drawRect(0,0,96,64,TSRectangleFilled,TS_8b_Yellow);

I more or less made an assumption of what you were trying to do, but I hope this helps!

I have to change the color of the screen and the code below works:

if(x < 120){
          display.drawRect(0,0,96,64,TSRectangleFilled,TS_8b_Yellow);   
        }else{
          display.drawRect(0,0,96,64,TSRectangleFilled,TS_8b_Red);   
        }

I want to set the cursor to the middle of the screen and check the color of the screen in that position. Something like this

display.setCursor(48,32);
if (display.Color!=TS_8b_Yellow)
  display.drawRect(0,0,96,64,TSRectangleFilled,TS_8b_Yellow);   

Thanks in advance

So the art template is useful, but is there any chance you can make the dxf for the cabinet itself available?  I'd like to make a couple minor changes and have my own laser cutter.  Pretty please?

New Product Ideas / MicroPython and or CircuitPython for the TinyZero

« Last post by alpierce on January 05, 2019, 02:18:36 PM »

I'd like to get MicroPython or CircuitPython running on the TinyZero board. The first bit of info I need is about the boot loader on the TinyZero. I am hoping it is the Bossa boot loader, since I am familiar with that and already have the Bossac software for uploading binary images. I have recently started using Python a lot more and it really speeds up the development cycle. It would be a great addition to the TinyZero.

Hello,

Thank you for this post, but i'm still running into some issues.  I just recently purchased the TinyZero and WiFi Tinyshield.  After completed the steps that you wrote out here (setting baud to 250000 and setPins), I get to the point where my test connection says "The Programmer is working!" 

When I attempt to update the firmware (WINC-1501  Model B 19.5.4), I get an stack trace error that says "Error while erasing flash memory."  i'm just wondering if i'm missing anything and if you could shed some light onto some other troubleshooting ideas.

Code: [Select]

java.lang.Exception: Error while erasing flash memory.
