Hello. I am making a USB controller using a Teensy 2.0 and I wanted to add a buzzer to it. When you're hit, fall, or die I want the buzzer to rumble for a second and then stop. I have no idea how to do this, so any help...
I have a teensy 4.1 board here on my desk. It is my first teensy project and my first contact to the arduino frame work. I started with PlatformIO and get a blinky program successful running. Now I want to test the...
So whats the catch? Well there are two.
Firstly TeensyCam doesn’t exist YET. After years of playing around with micro based cameras I believe Ive finally come across something that should work properly. For the past...
In the Audio Library of the current Teenyduino version 1.56 i may have found a bug in the code for the Freeverb object (Stereo version).
In effect_freeverb.cpp in the function definition for...
Hi all,
I am trying to get some version control and a somewhat better IDE set up for my Teensy programming and am having a hard time getting going. I usually like to use git for version control w/ VS code. I've...
This may have been asked before but I can not find it.
In the audio library DMA is used to read blocks from the audio codec chip and then it appears that a software interrupt is triggered to process the data by the...
Hi All,
I am trying to down-clock my Teensy 4.1 to lower power consumption, and am experiencing a bizzare issue with SPI.
I am connecting an MPU-6500 IMU breakout board to the 4.1's SPI1 peripheral, and using a...
I'm trying to design a board with micromod teensy to include both a PSRAM and sd card slots so I'm in need for the pins that these things use, 42-52.
It seems that the m.2 connector's pins 60-62-64-66-68-70 are...
@mjs513 - @ khoih-prog - Something very peculiar going on. In doRetrieve() I have:
int spaceLeft = data.availableForWrite();
Did a complete grep of WiFiNINA for "availableForWrite". It was not found. Where is it...
I don't understand how this design works with LED1 (pin 3) connected to a LED tied to 3.3V. Maybe the LED's forward voltage is enough that it doesn't conduct enough at startup to overpower the weak pulldown resistor...
I'm a little confused, and I may be looking in the wrong location, but the current Teensy LC uses the MKL26Z64VFT4 (according to the schematic). According to the KL26 sub-family reference manual...
debug_tt.h looks like something written here ... it can be commented out (as in p#3) or removed.
It is not something included anywhere or that generally evolved to anything useful across the evolving MCU's in use.
Not sure what buzzer you are referring to but these are what I've used.

Just send a pwm to them of a frequency of your...
I have these three dongles and all connected.:

Ha yep, I just need to be better at the "telling" part. :)
So now that this issue is fixed for me, I’m wondering if I’m the only one that’s experiencing this? (Seems like it hasn’t been an issue for anyone since...
I bought three different dongles from the suggested ones from that particular thread. All three dongles showed connected.
After uncommenting Debug Line, message appeared...
I' very disappointed. From my point of view I freely avaibale SWD or JTAG connecter is a must have. The board has a very powerfull MCU but without a debug connector not usable for me.
little update:
Finally got it working using this driver:
https://github.com/blazer82/FT81x_Arduino_Driver
(plus a little of bitbanging on the SPI)
Since mk66fx1m0 is out of stock, we cannot assemble our own PCB...
Only a few known Bluetooth dongles tested to work well - there is a thread listing the ones used and found good.
There is a DEBUG #define commented out in the main file, enabling that will provide some feedback on...
Thanks very kindly. I wrote some code but i can't get pass a complete pairing. I modify the code below so many times that I am the point right now of guessing, which that's why I need some help. Also, when compiling the...
The MicroMod Beta thread has development with that version of Teensy. @KurtE of course and @mjs513 did lots of heavy lifting there. IIRC it was mjs513 that hooked up the Processing transfer and sketches sending that...
No there is no hardware debugging available.
However there are debugging facilities, especially using VisualMicro with VisualStudio, see here.
I use it all the time and would not be without it. It also does not suffer...
Trying to write to the flash, I had all kinds of instability issue. I finally have to relocate almost all the code to memory. The complication in my case is the use of FreeRTOS. It doesn't seem to recover properly after...
@wwatson - @ khoih-prog
Don't think its an SPI issue either since we were able to transfer files in one direction. As for using the AdvancedWebServer - not 100% sure whats going on with that. I just ran the...
@PaulSoffregen I switched to the Richard-Gemmell I2C and repointed the Audio.h libraries to that instead of Wire and this has restored I2C connectivitiy while using I2S Output
...
SysEx Dump works now. See short video.
It was a bit more complicated than I thought. First, conversion routines had to be developed for all 212 parameter values in the Jeannie, which convert 8/16-bit integer values...
This is probably best to approach as 3 smaller projects.
#1 - Get the software to send something when the event happens which you want to cause buzz. Maybe try to have it change the LEDs on your USB keyboard. This...
@mjs513 - @ khoih-prog Well did some more testing after work tonight and SPI is working with WiFiNINA and the T4.1. sendData() and getData() do not have a problem as they are also used for all other file operations with...
Was wondering if it is due to 32KB code cache? XIP or any Flash code (especially on locked/encrypted) 1062 would need to be made available/plain to run. If that code then blocks flash access during writes (also EEPROM...
