Yes, I was given an old copy of the whole Arduino 1.0.5 folder & Teensy 3.0 device and was given a task to make it work on Teensy 4.0. Don't worry, backup is safe on cloud and I also only made changes on files in Arduino 1.8.15 folder which I...
There may be other issues, but your spi_Write function is calling SPI.transfer(data_byte), which sends one byte, but data_byte is type uint16_t, which is two bytes. You at least need to send both bytes of the data value. You might want to rename...
Hi,
I was just typing what @joepasquariello said..
A couple of other points you might want to look at:
- have you got the right SPI_MODE? The data sheet says it clocks the data on falling edge (SPI_MODE 1 or SPI_MODE2?)
- in loop you're...
I'm using the adc .h library in an application requiring high speed 12 bit a/d conversion by interleaving the two A/Ds on a T4 or T4.1 running at 600MHz. The interrupt service is called every 2 microseconds by the timer in the Timer.lib. The bug...
The gumstick-sized Teensy 4.0 made this project possible! Fender's iconic Stratocaster's control cavity was routed to accommodate a few analog pots and a dual-pole 5-position blade switch but I've crammed the Teensy, a stereo codec, two RGB LED...

After thinking about your goal--collecting RMS voltage data, I decided to try a software aproach that relies on a single ADC channels collecting data at 50KSamples/second. Other than the ADC channel (using timer-controlled ADC collection), and...
Hopefully it is CERT trust that will build with more exposure as it is NEW - even though PJRC NAME is common from prior.
Still needed Double Keep - with EXE name change it will still be inclined to show this as 'not commonly downloaded':
Until...
I’m not sure if it helps, but the QNEthernet library can do raw Ethernet frames. I’m also making a small update so that the library can be built without any IP support (IPv4, etc., and any protocols built on top), should you not want those...
Does right click properties show it as BLOCKED - - not seen that here but downloads can get marked that way too and require flipping that switch to allow it to run.

Hello.
I have been trying to get this DAC80502-01 evaluation Board to output a signal other than zero.
https://www.digikey.co.uk/en/products/detail/texas-instruments/DAC80502-01EVM/22188397
In the the 8051 datasheet, it states that the CS pin...
Getting the hardware integrated on your board is probably the easy part, the coding is the part that is harder to accomplish.
You still may want purchase the shield as a reference for the person is doing the actual coding...

Best thing you can do while you wait for replacement hardware is extensively test your application running on the damaged board.
If it runs successfully for the rest of this week, perhaps that will be good enough to meet your deadline next week.

Maybe. There is no 100% certain answer. The power quality will be lower, but I can not predict whether the lower quality will manifest as problems in your application.
You should begin testing to answer this question for yourself, specific to...
I am using a SD card for data logging will the noise caused due to absence of C21 decoupling capacitor cause problem to the SD card or any serial, I2c protocol Or pwm signal. As I am using these. I am also using a analog voltage sensor but I can...
Yeah, I've been digging into it since yesterday and EtherCAT works a bit differently than I thought it did. The master can run on a standard ethernet port with just some software. The slaves need an EtherCAT Slave Controller or ESC. The ESC has...
R2 is used for the red LED which shows bootloader status. Teensy 4.1 can work without this LED.
C21 and C29 are 3.3V decoupling capacitors. C21 is close to the SD socket and QSPI pads. C29 is close to the ethernet chip. Teensy 4.1 can...

Had a quick look at the EasyCAT shield and related library. The shield uses a Microchip LAN9252 EtherCAT device controller, not a 'standard' Ethernet controller.
I assume that the LAN9252 chip probably takes care of the EtherCAT protocol...
Soon, i went into the latency rabbit hole trying to optimize it a bit, but it would require a new audio system.I'll leave it for now. It's perfectly usable and playable.
I think i'll add a master high pass filer, have it on my second IR cabsim...

While desoldering the teensy 4.1 i broke R2,L2,C29,C21 l2 i can short circuit but what can i do for r2,c29,c21 what if i do not place them aur short them or what is the easiest and fastest way to make the teensy work please help me there is a...
I'm guessing you're dealing with code someone else wrote on this PC?
If so, please first make sure you have backup copies of all the files. Especially if the PC you're using has the only (very old) copy of the working (with Arduino IDE 1.0.5)...
Sorry, again at least for me it is really hard to tell. The only thing that Arduino 1.0.5 tells me, was it was done a long time ago. A more meaningful indicator might be what version of Teensyduino, but not by much. The USB types are part of the...
Just a guess, but this may be a reference to a company named Real-Time Systems. Among other things, they make software tools to allow visualization of data from embedded systems.

Do you have a suggestion on how to port USB driver using the available USB type in Arduino IDE 1.8.5? I tried using Serial USB type and modified the usb_desc.c & usb_desc.h with parameter values from the "Real-time Systems" USB descriptors...
The idea is to write a firmware for a simple USB driver application on a Teensy device. The application is simply to read inputs from I/O (potentiometer or button) or writing outputs to LEDs. I am pretty sure this Real-time System option type...
Arduino IDE 1.8.5 is the oldest supported. But the IDE version probably isn't your main challenge. If you have code which was written for the Teensy 3.0 hardware, porting to Teensy 4.0 means rewriting the low-level USB code which actually...
Did a quick scan of https://www.pjrc.com/store/teensy41.html and not seeing any notes on previously discovered behavior of pins #24 and #25 during Upload where they are driven high in some fashion. Seems that and added note when using a locked...
Actually I found one that works for CAN FD that I haven't tested with the regular CAN: https://github.com/cburgess5294/Arduino-Teensy41/blob/main/TEENSY_4.1_CAN_TEST_2.ino
There are a couple ways, but the easiest is to just hard-code it:
line 209 of RS485.CPP was changed to the following
RS485(Serial5, 20, 255, 255);
In my case, I was actually using a MAX3232 (RS-232 doesn't transmit/receive on the same lines) so...

The code at that link isn't quite a Teensy-compatible library. It does show how to use the hardware to collect analog data. With a wrapper to handle the Teensy SPI transactions, it might save a lot of work. A complete library should have...
I've seen a few posts from a couple years ago but nothing with much info. I've seen some projects using an Arduino and this ethercat shield:
https://www.bausano.net/en/hardware/easycat.html
It seems like it would be a hell of alot cheaper and...
Sorry, I am pretty sure there will likely not be support to run on Arduino 1.0.5 with any version of Teensyduino that supports the Teensy 4.x boards.
Sorry. I personally have no idea what the Real Time System Custom USB is or was? Maybe others...
Pin #24 and #25 during programming receive some level of 3.3V - enough to light an LED DIM or Bright. Not seen on other edge pins.
That has been noted if not documented and needs to be considered in use of those pins.
AFAIK: This is the first...
Yes, I just got back from testing, and when pin 25 is held to ground, it cannot be programmed when the unit is locked.
I haven't yet tested to see if that will affect my application, as I am using pin 25 as an address line. Does anyone think...
Thank you for your advice, impossible to make a dividing bridge with resistors (too much parasite), I have a -40 dB attenuator but I think the level is a little loud for a microphone input (generally around -60 dB). Probably I'll enter the signal...
