Re: JackAl System Preview

Hi Gilles:

The PCB will be sold separately, but with all SMD components in place. The card works with either display size.

The Teensy is Arduino compatible, so pretty much anything you learn for the Arduino is applicable to the Teensy...only is over 10x faster, and have a lot more resources for you to use (memory, I/O pins, etc.). My book, Beginning C for Arduino applies to the Teensy as well.

Hi Kack?& Al

I have two questions :

1 - Can we buy only the kit of the card?
(I already have a TFT 5 "and a Teensy 3.6).

2 - Do you know a book about Teensy to learn how to use it or have written one?

All:

As some of you know, Al Peter (AC8GY) and I have been working on a display replacement for the ?BITX for quite some time. We have a preview video that gives an overview of the JackAl system. There are some software hiccups in the preview that should be fixed soon. We just sent Rev 4.0 off to the PCB fabricator which should be the final version of the board. All SMD's are on the board. JackAl makes use of either 5" or 7" 800x480 displays ($34-$44) using the Teensy 3.6 microcontroller ($30) and its companion audio board.($14) for the DSP. The Teensy has 1Mb of flash memory and 256K of SRAM, or which we are using less than 20% and 15%, respectively. We have also brought out a dozen "empty" pins for you to experiment with so, along with the I/O pins, there plenty of resources left to play with.

BTW, pay particular attention to the ALS Tuning it uses. It really makes it so much easier to zero in on a station. Details are in the video, but if questions remain, let us know.
