Yeah, this chip really wants a well tuned reflow soldering oven! I'm trying again... this time with 8 resistors. Looks weird, but I can visually inspect every pin.

Happy to report SD listfiles example does see the chip and shows the 5 files I copied onto it with the card reader. If anyone wants to reproduce this test, see msg #10 for link to the Zetta-to-SD adapter PCB.

Glad it worked. :) Yes, please do add project info if you can share. I believe the blog queue currently has a few months of pending articles, so please understand anything "new" today which isn't a special time sensitive event will likely...

Paul, First: thank you!!! It's been a busy spring and start to summer, but I finally pre-tinned the pads on a new Zetta, hit it with hot air on the PCBA, and she started working right away. I really appreciate the insight. I'm still getting...

Hello, I've had code running on qty 2 Teensy 4 and then 4.1 for quite a few years detecting the bits on a serial stream with a Tamagawa (qty 4) 23 bit absolute encoder. The PCB I am using has serial 3 and 4 and the bit stream is 2.5 mbs, and...

It's been awhile but try this code: // This sets the system time (NOT the Teensy RTC Clock) setTime(tt); // seting the System Time Library only here. // now we can use the system time to update the Teensy's RTC bits // This sets the RTC...

This is the code which implements Serial.availableForWrite() on Teensy 3.6. https://github.com/PaulStoffregen/cores/blob/master/teensy3/usb_serial.c#L240 To briefly explain, it first checks whether a packet buffer is allocated, and if not it...

Just want to confirm I'm planning to merge this in 1.62 or 1.63. Immediate plan is to wrap up 1.61 sometime next week. My immediate plan for 1.62 is upgrading the gcc toolchain from 11.3 to 15.2. First beta for 1.62 will have the new toolchain...

Hello Teensy Warriors, @bk40, I can relate to broken devices and code. Hardware is incredibly unforgiving, and requires money, time, and patience. I've been at this for a long time and I've failed to finalize many designs. I'm hoping my momentum...

So for one final test, I reconnected to wire to Teensy 4.0 to see if it survives abuse with this circuit having only 330 + 22 ohms. I'm happy to report Teensy is working fine. The voltage while high is 3.409, not too bad. But you see Teensy...
