Six months down the line and the Teensy is still performing flawlessly!

Yes good point. Diode added.

Hi All, Why can't/shouldn't I: Cut the said solder jumper, Then add a diode across as per my crude drawing, Besides the Vf surely this would protect the USB port but still provide power to the board from the USB, when I am in the bushes and don't have a 5V supply handy.

Just to report back, I successfully locked my lockable Teensy. Thanks again!

FABULOUS thanks a mil! I'll do exactly this ta!

Herewith the beta tested version of my latest project. I used a Teensy4.1(T41) attached to my custom made board, to capture the overspeed of vehicles and then snap a picture of them. The T41: reads the vehicle speed, takes a snapshot via an instruction to a HIKVISION camera, Saves the image...

Thanks Tom, These LEDs have a single replacement capability, which in our line of work is priceless. The APA102s take too much skill for the average Joe to replace/solder. Over the years a lot of designs have been tried and they all have their drawbacks. I have built sigle LED boards with...

For context, here is a trailer I have just reconditioned , using APA102 LEDs , and it draws anywhere between 30 to 60amps! Notice the large Solar Panels and Battery Boxes needed!

Hi All, I am planning to try this. I have 200 of the new ws2811 26mm LEDS. Here is a pic of them: And I am planning to place them in a grid of 20 cols by 10 rows. as follows: What I dearly need to do is limit the amps draw. I am in the VMS sign business and power here in Africa comes...

Yes Thanks Joe, I mentioned the T41 in the heading. But I hear you on the power requirements. I did read in another thread on this forum about the power consumption on VBAT and if I recall correctly in was in the region of 40 days. Which then makes sense to use an external RTC if power is going...

Excellent suggestion. I only need a minute or so resolution so writing once a minute would be quite fine for me!

Here is a curved ball question: On my old projects, I use an MCP79410 RTC chip. One of the nice things it has is two registers to capture the time of power failure and restore. (Provided you have the VBAT active) I was just wondering, is there a neat way to do it on the Teensy or should I...

Dear webmasters, should the following code snippet on your page: https://www.pjrc.com/teensy/td_code_security.html Not be an ampersand? That code does not compile.

Fabulous ta!

Thanks Paul. And am I correct in assuming the code I posted in the original post above will retrieve that MAC? (using the QNEthernet.h)

Maybe Shawn can help me? I want to use a unique ID on the Teensy. Does the PHY chip on the T4.1 have a unique MAC address? I see one can get the MAC as follows: uint8_t mac[6]; Ethernet.macAddress(mac); // This is informative; it retrieves, not sets printf("MAC =...

Thanks Shawn. I used your QNEthernet and the Ethernet kit from PJRC, and it works a treat! I am gobsmacked at the speeds I am getting. Revolutionised my project TBH.

Just some feedback, I used the following code with the QNEthernet library char url[300]; sprintf(url, "POST /xxx.php HTTP/1.1\r\nHost: lexxatrexxa.co.za\r\nontent-Type: application/octet-stream\r\nConnection: keep-alive\r\nContent-Length: %lu\r\n\r\n", bxctr)...

Thanks a mil

And just to be sure, the QNEthernet works on the Native Ethernet port of the Teensy4.1?

AH OK, thanks a mil! I shall do so!

Hi All, I have just ventured into the TEENSY world, coming from the STM32 world. I have a sketch, that triggers a HIKVISION camera to send thru a photo. All works well. What it can do on the TEENSY4.1 so far quite successfully is: Trigger the camera using the NativeEthernet port (ISAPI and...
