I just found a good deal on an NXP evaluation board. Hopefully it has enough I/O so I can use it to debug my Teensy programs before moving them to the Teensy.

I think this is on a lot of peoples wish lists. Debugging using printf and IO pin toggling is fine for smaller projects but once you hit a certain level of complexity you need real debug access. With a part as powerful as the teensy that lack of...

Paul - if you are planning a Teensy 5... PLEASE bring it to us with debug. I'm begging you here :).

You are so right! The two signals - SWDIO and SWDCK - are NOT CONNECTED at the Teensy. Geez, they could have mentioned that in the ad copy. That's a hundred fifty bucks down the drain. The artwork on the board is really small - probably...

Hello! Yesterday, I received a "Segger Jlink Edu Mini" debug probe. This is supposed to be compatible with all 3.3V ARM Cortex processors. It supports JTAG and SWD protocols. Or so they say... Has anybody got SWD debugging working with...

It's the ATP board. Now I need to figure out what goes where. First of all, I need SPI for my display. And, I think an I2C for touch.

It's a Unitek Y-3198 6-port USB-3.0 hub. I bought it in November of 2019. Works fine with my cell phone.

Ubuntu Linux. I did accomplish one download. Now lsusb shows nothing when I plug it in. In /etc/udev/rules.d, I see 00-teensy.rules, dated March 19, 2023. I have a Teensy 4.1 also on the desk. That one works fine. This device shows up in...

The plot sickens... Apparently it does have the boot chip. Says so right on the schematic. So have I bricked it? When I momentarily hit the "boot" switch, the "prog" light starts to blink on the Teensy card. But there is no USB device. If...

Hello! I just got one of these bad boys. A micromod Teensy card, and an "All ports brought out" micromod motherboard. Put the two boards together, plugged it into a USB C. OK, the micromod port came up in my Arduino IDE. Just to see if I...
