Great! After playing around with it I am able to read the program on the flash simply by reading a variable pointed to the flash address, I thought I would need a special function to read from the...

Thanks for the clarification and all your work on this, this should work perfectly for my needs I just need to send the file over ethernet. Assuming I verify the program with either a CRC or sending...

No worries, in my case I am not using LittleFS, I just wanted to use the flash space between the program and EEPROM for buffering the new program. With the default offsets I was having the issues...

I came across the same issue as @ipaq3115 when testing this, I also use the EEPROM in my program and when trying to flash I get "buffer = 0K FLASH (601FC000 - 601FC000)". I decided to use a ram...

I have an application where I am communicating between a teensy and PC, I was originally connecting a Teensy 4 to the PC using an RS-485 bus in anticipation of a long distance run but have since...

Nice work! Glad to see someone else take on the challenge, it sure is satisfying when you get it working. My setup is VSCode issuing commands to Arduino_debug.exe to build and JLink.exe to upload.

You should be able to establish a J-Tag connection as long as you connect everything between the Teensy and the MKL02 except TDO, TCK, TMS, TDI. Pins 6, 8, 5, 7 respectively and connect those along...

Paul sells 3x2 pins and sockets and they work great for custom boards. No clearance issues on my end. I just used this footprint in KiCad https://github.com/XenGi/teensy.pretty
You can see an...

Nice to see someone else giving this a shot. I have come a long way since my last post, I will share here shortly. One of the issues I had was that the pads were so close together there wasn't much...

Arduino CLI 0.19.0 was just released with support for pluggable discovery. This is good news, I assume Arduino CLI and Arduino IDE 2.0 Beta are finally ready for Teensy support.
...

That is a problem. Pin 10 should be pulled high by the MKL02. If this is LOW, I believe pin 9 will also be low which is your power on reset. This means the processor is being held in reset and it...

Are you powering it with a LiPo? I remember reading that the ESC has regenerative braking and it could damage a power supply so you had to use a LiPo to power it. If so disregard, I just remember...

You could try his code before going ahead and buying one although he explains how he only could get it to work with a KISS ESC, not sure the reason. It should work on either of your Teensy versions,...

Are you using a KISS ESC? If so, Give this a shot.

Did you try pin 4? It looks like ESC 1 should be on pin 4 according to the readme on github.

Sorry for the simple question, I will try and look deeper into it tomorrow.
Which version...

How far did you get with attempting to use the teensyshot library? At first glance it looks as if once you load the program on to the Teensy you need to write a program on the pc which sends data to...

This may do what you need but it is $199. https://www.pemicro.com/products/product_viewDetails.cfm?product_id=15320138&productTab=1
Only other thing I could find is this article....

It's normal. If you do not have a cable connected it will hang forever.

You can see it on line 293. I believe it was left that way to be consistent with the original Ethernet library but you can...

First thing I found was this. Not sure if this is related but it's worth a shot either disabling the timer before calling parsePacket then re-enabling it. Alternatively call noInterrupts() and...

You can usually put multiple slaves on one SPI bus and the CS pin will tell the slaves when they are being communicated with. I believe you should be able to get rid of one of your spi lines and set...

You could use IntervalTimer if you plan to run these at a fixed interval. This is what I have used to acquire data from SPI and pass data to the main loop....

No problem, hopefully that's the issue. I'm not even sure if UDP_TX_PACKET_MAX_SIZE does anything inside of the library, I quickly searched for it but I didn't get any hits. I would assume it's just...

I noticed you are running outside of the leds array, the length is 14 and you are accessing up to packetSize which is 24,24,27. It could be causing your problem. The garbage data in your third...

I have a project in which I am powering a Teensy 4.0 with 5V directly from a power supply and I have the trace cut so I can still use the USB for acquiring data over serial. I noticed recently that...

I will probably upload the files and/or post it on OSHPark. It requires hot air, good soldering skills and flux.



I would love if they did this. I feel as if they are waiting until they make...

I have been working on a Teensy 4.1 debugger mod for a month or so now and I figured it was in a good place to share my progress. This project started by de-soldering the MKL02 chip, soldering magnet...

That's great Paul! I will be sure to use these for my board. Is there a recommended footprint for the header? I'm sure I could use a similar part's footprint and it would be fine but just to be safe....

No problem. Hope it is really as easy as swapping out a part rather than needing another pcb manufactured. I have been fine so far with user libraries, but it is always good to double check them for...

Thanks for the suggestion, this is what I am after for sure. I have not gotten around to making the next revision of my board yet but I will definitely consider these. Since I have posted this I...

Looking at the J0011D01BNL datasheet, it looks like the pinout is different between the J0011 and the J1B1211CCD that PJRC uses?
Here is the J0011

and J1B1211CCD

I am making an addon pcb for the teensy 4.1 which will need to passthrough the 48 outer teensy pins along with the 6 ethernet pins. I will use two of the 24x1 Sockets on the pjrc store to pass...
