Arduino mixed up with a Pi? How does that work?

have you installed teensyduino into the arduino IDE?

I didn't have to remove HOSTPORT on mine.  I just followed the original instructions to use pitncparams utilities from the old TNC-x website.
Manual showing all of it is here: http://tnc-x.com/TNCPi.pdf
work just fine with the TNC-Pi9k6.  just went downstairs to verify.  Also you'll want i2ckiss as well.  it maps a pseudo com port to the i2c address

No, the TNC can use i2c for communication, but you have to configure it in the firmware, you can't change it with pitnc_setparams.

To enable i2c remove HOSTPORT from TeensyConfigPacket.h. You can change the i2c address by changing the #define I2CSLAVEADDR

Ok, happy to be wrong.  Looks like an easy enough change.

Blue tooth and SD cards? #bluetooth

Jay Lijoi
 

Good afternoon,

Scenario: I use SD cards in my PI for different applications (nothing new here). One has HamPI on it and another Manjaro, etc. I want to use my blue tooth mouse and keyboard to reduce desktop cables and preserve usb ports for other uses.

First I paired the mouse and keyboard while running HamPi. Then when rebooting with Manjaro SD I had to go through the process of pairing again. Now when I switch back to the HamPI SD it doesn't recognize the mouse or keyboard, it says they are there, but won't connect. So I have to pair again, and then I loose the pairing when I again when I change to a different SD card. 

Is this normal?
Is there some kind of randomness to pairing?
Is there a way facilitate using the same mouse and keyboard accross different SD cards withour the need to pair every time?  
Or, am I just being oblique and missing something simple? (I didn't want to say stupid.)

You might consider something like this. Closer to a signalink but less expensive, and as I evaluated it, a better design.  They make several versions at different price points.  No connection to the company, just a satisfied user:

But it’s for video. I got a Soundblaster on ebay a few years back for SDR (I, Q). It works great. Cost was around $30. 73

I use the MoPi2 Hot-Swap Mobile Power. It fits with other hats. It has two 6-24V inputs and a charge input. In my case, I run 12V into the main power input and a small battery pack on the other the charge input keeps the battery pack charged. It can go to a small solar panel or whatever.

It has a push button to start and shut down the RPi so you don't have to pull and reconnect power.

It also has a switched 5V to operate external equipment.

It can be configured for various input types and voltages. If the primary input drops below a preset voltage, it switches instantly to the backup input. Depending on programming, you can have it perform a graceful shutdown on loss of primary power.

In my personal case, it is used on my APRS installation in my vehicle. Primary power is vehicle primary power. I push a button to boot up, which operates a relay providing power to the radio. My APRS starts up automatically on boot. When leaving the truck, I hold the button for five seconds and it closes the applications, gracefully shuts down the RPi, and releases the relay shutting down the radio.

Available from DigiKey and others. Read about it at https://projects-raspberry.com/mopi-is-mobile-hot-swap-and-247-power-for-the-raspberry-pi/

Re: Pi Goodies #raspberrypi

Dean;
Allan is fine.  Thank you for asking.
I do like the idea of having one battery pack (with appropriate dc/dc buck or boost) to run the rig, Pi, and any other items.  That is an option that I am also looking at.
Again, I am so very new to using a Pi (and even digital modes in general), and am just slowly returning to being a Ham again after "life" got in the way for some years.
I guess I need to consider the pros and cons of a single battery as a power source for all versus separate batteries/sources for the radio, the Pi, and any other items.
These little "backup" style batteries just seem kind of cool in a way but I did not know if they have really been used much in the real world.  Or if they are just gadgets more or less.
Thank you so much for your thoughts and input, and I always enjoy hearing how others approach things.
I am very much in the learning phase at this time.

Re: Pi Goodies #raspberrypi

Dean K5MPG
 

Lloyd or Allan (which do you prefer)?
I don't have feedback on those items.
I run a dc/dc converter that works well so I can run off the same battery as the rig. I can use the dc/ dc converter power the pi or to charge my ipad or the power brick and, also have tested powering the pi with an Anker "power brick" and that ran the pi for about 14hours (results may vary for you).
I believe  the anker power brick is a 20000mAh. 
my battery is then charged either by commercial mains OR by solar panel from Renogy.

I have a Soundblaster 7.1 with SP/DIF optical available, the Sabrent is all I need. It has no issue with consumer line level (-10 dBV) audio on my pi400. 73
