  • I have tried to use serial output to send trace to monitor. My usual approach is to do a setup and trace. I am getting no output and no lights on TX and RX. It appears that serial is going to null.

    void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(LED_BUILTIN, OUTPUT); Serial.begin(115200); Serial.println("Blink Startup"); }

    // the loop function runs over and over again forever void loop() { digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second Serial.println("Blink"); }

    But then I discovered I am not up-to-date on serial (amazing we are still innovating in this old stuff) and now have it working:

    // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin LED_BUILTIN as an output. pinMode(LED_BUILTIN, OUTPUT); SerialUSB.begin(115200); SerialUSB.println("Blink Startup"); }

    // the loop function runs over and over again forever void loop() { digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second SerialUSB.println("Blink"); }

    Left comment here for anyone that makes the same mistake...

  • I cannot get the board even to be seen by Arduino IDE. Not sure if my board is defective...I can use the same cable and version to talk to STEM. So so a bit frustrated by this board.

  • Issue fixed and IDE works now. Thanks!

  • I needed this to run on AdaFruit's CircuitPython. I like the 3.3V instead of having to add hardware to convert 5V. I also needed it to run I2C as I wanted the GPS to be on the serial pins for my new Express based project. I got it all to work after some effort--mostly having to read the directions. I have the combined code from both Sparkfun, AdaFruit and me here: https://github.com/alohawild/Maven/blob/master/OpenLCD.py. Harvest the code. I have tried to document it and make it clear and include Sparkfun's notes on how to use the OpenLCD based code.

  • Thank you for the information, and I love the view of your first tariff! I think the cost of checking and rechecking costing is going to be hard on all importers. The cost of a mistake is just too high and then passing on an invalid expense of tariffs to the customer is going to damage your relationship--it is much more ugly than folks understand. Now it will be too easy to send work out of the USA and then import a finished good without tariff--the tariff avoidance process will make the existing value chain more inefficient. That is why we did not have them before, but that should be in a letter to someone else--stepping off the soapbox. Thank you for all you do and know we will be buying for you--even with tariffs! (Commenting as myself and not in anyway for my employer).

  • I have no idea what I would ever do with this, but it is great to have something this edgy available to us makers. Thank you again for looking for things I do not even know I needed.

  • I do not plan to do this but it was interesting to see a bit of insanity and science at the same time. I have wondered about combining chargers like this. Very interesting. I think it would be wild to split this and do 1/2 in serial and the other in parallel. Thanks again for doing this.

  • Ok. I will try to make that work.

  • Or maybe just nine as that is more standard level.

  • I would rather have 7 volts as the regulators often drop the power too much on my projects. I find 5V hard to use. Thoughts?

No public wish lists :(
