Thanks, Paul Indeed sorry for the inconvenience.

Thanks, GremlinWrangler. I have to code it for once only till there is a new update. So if I remove the bootloader after burning there won't be any resetting of controller because of some watchdog or any other issue?. Also, I'm using the same schematic as per Paul which is present in pjrc...

Hi, Paul kindly let me know if I burn the teensy 3.2 with bootloader and remove the bootloader will the controller perform or not?

Kindly let me know can I remove the bootloader once the controller is programmed?.. Means If i remove the bootloader will controller perform the same task which is burned?.. or it will not work?.

Okay let you know the result.

Hi Frank, I guess my connections are okay because sometimes it works and sometimes it don't. SF(pins)-------------Teensy 3.2(pins) 1---------------10 2---------------12 3---------------GND 4---------------GND 5---------------11 6---------------13...

kindly update on my above query.

Hey, guys I have attached a new design kindly let me know its okay or not?

hey, HWGuy Actually I was running out of jumper but I shorted the supply in the bottom. Thanks for the keen observation.

Schematic PDF.

Attached is the schematic. I Guess I only connected VOUT33 and VBAT to 3.3 v but not VREGIN. How to attach pdf?

Hi I have developed the custom teensy 3.2 with my required extra module and its not getting flashed even with specific bootloader. while burning what i saw is the programming windows just comes and goes like a flash. Kindly find the PCB images in attachment. U1 is bootloader. U3 is...

thanks, RichardFerraro... The above is working fine but need something which again not check the condition as my program can be anywhere at any time, with above I need to be precise that everytime my program should check the condition. The worst case is, if my program gets stuck and at the same...

Inside interrupt below is not getting played. for (int thisNote = 12; thisNote < 36; thisNote++) {//0; thisNote < 24; thisNote++) {// freq123 = 43-(thisNote-12); tone(9, freq123*55.2369,960); delay(6); // creates delay of 6 ms //tone(9, musicTones[thisNote], 40)...

I'm using the same above interrupt program. I have connected one button on pin23 and when I press it very much going to isr but inside isr I have written tone_melody program which should get played but its not playing. Kindly let me know is there any connection between the tone_melody program...

No, I just replace the teensy controller with the new one.

This error because in new core you have given better security solution and .hex error because earlier It was not working. Paul, 1 more concern, suppose I burn the .hex file created in Arduino 1.6.9 with new core library with default setting via SWD mode via ULINK2 debugger without using...

But Arduino 1.6.5 runnning fine and my firewall are off. The problem I'm facing with Arduino 1.6.9.

And also new cores dont work with Arduino 1.6.5

Whenever i use the new cores library I get below error for Arduino 1.6.9 or 1.6.5. Opening Teensy Loader... Unable find Teensy Loader. Is the Teensy Loader application running? Error compiling.

Can I directly copy the cores of Arduino 1.6.9 to Arduino 1.6.5?.

Hey paul, how can i update my k20dx128.c file as these files runs on Arduino 1.6.9 and with this version I'm facing problem. Kindly tell how can I update cores files for Arduino1.6.5.

For my testing purpose, I changed the teensy 3.2 controller with the same new controller.

Yes Paul I'm using the teensy3.2/3.1 board, only change I have done is I have placed a new controller in board.

When I push button nothing's happen and yes I programmed with 16Mhz with no USB and it worked before.

Hi, I have replaced the controller of teensy 3.2 with a new one and I'm getting some ZoneAlarm error. Kindly find the image to see in details.

Hey, Paul, If I burn the .hex file generated by Arduino IDE for teensy 3.2 in blank MK20DX256VLH7, Does it lock the controller or not?.

Hey, Paul, I'll let you know in detail as I have to gather points which I have to write here. Before that can you tell me is there any way to do it?.

Hi Guys, Even I'm facing the same problem, I have to record the sound through electret mic and before feeding to teensy 3.2 I have to amplify it with max 3.7v preamplifier, as I am using 3.7V Li-ion battery. Maybe the issue is because of ground loop, so kindly suggest what to do to get rid of...

Can we include the RTOS in Teensy 3.2?.

I already converted the .WAV into an array but not getting the same efficiency as .WAV file.

How can I keep my 106KB .wav file in teensy 3.2(within Microcontroller) and play via DAC? As of now, I am keeping mine .WAV in serial flash or SD card. As I am just using 7% of program storage and 9% of dynamic memory.

Hey, Paul, waiting for the contribution.

Hey, Paul, I'm eager to work with you just let me know for Audio in Teensy LC exactly which part I have to look into.

Hi Paul, Can I use PWM as audio output in LC?..As I am getting error for below code. #include <Audio.h> #include <Wire.h> #include <SPI.h> #include <SD.h> #include <SerialFlash.h> #include <Bounce.h> #include"AudioSampleTone2005.h" //AudioPlaySdWav playWav1; AudioPlayMemory...

Hi Paul, When can I able to use the audio library for Teensy LC?..

Dear Dear Dear Paul again your suggestion worked thank you so much. VBAT was the problem.

yes paul thats right but I'm trying very hard to kill my problems. Thanks for input i'll let you know the fault(If i'll find it).

what all the pins I should connect between MK20 and MKL02 through tri-state. Also, suggest some tri-state ic's which are easily available.

I Guess you have seen the schematic so based on that do I need to completely remove the bootloader or if its power off its okay. As the pull-up connection of 10K is still not working in reset line. Bootloader connections are still present though its power off.

As I can able to burn the .hex file generated by Keil in blank mk20dx256 but how to make .hex file generated by Arduino IDE working in blank mk20dx256. I have taken the .hex file of blink example and I succeeded in burning in blank mk20dx256 but the pin no 50 is not blinking. Let me know what...

Hey, paul is my approach is correct or I'm wasting my time. Also please tell me is this the default behavior of bootloader towards controller when not powered or something wrong with my circuit.

Hi Paul, I tried connecting the UC pins(25,22,24) as high impedance but the same result. Let me know my way of connecting pins as high impedance is correct or not. Also, I got you correct or not.

OK....................

Hey, paul hoping to hear from you.

I have used the same connection as Emach and can't change because I have mounted the Winbond on board kindly let me know any other solution based on same connection as I'm facing the same problem.

Hi, I am using Spansion-S25FL208K0RMFI041(8M) and I am getting "The flash chip may be left in an improper state"; "You might need to power cycle to return to normal"; error while running the Raw hardware test program. Kindly let me know what can be possible reason and solution. Even I tried...

No Paul I don't know that logic.

I understand everything Paul but I'm about to finish my project which has a huge value. If possible kindly help me to figure this out.

Hi Paul, Attached is the schematic of which i made the PCB and I only checked the blinking program and its working fine. But when I disable the bootloader by not shorting the J14 the LED stops working. Kindly tell how to remove the bootloader once the programming done. Also, when I disable...
