BASCOM TV short review
This is a photo of the TV display function working on a flat panel LCD TV set
The actual display is perfectly straight, some distortion is seen here caused by the camera optics.
Company licence (unlimited copies for company use) now available for commercial use. Includes built &
tested board, pre-programmed sample IC, TV generation software module
including all pixel data which can be edited, plus full support from the
developer by phone and e-mail.
TV Code Features:
* Generates a 55 column color TV character display from an AVR MPU without any extra ICs
* Connects via a standard SCART socket giving a sharp RGB output signal (not composite video)
* Flexible RAM use - display RAM can be as large or small as needed
* Completely interrupt driven software - transparent to user
* Character pixel data can be edited or replaced by the user to allow custom characters
TV software can be customized to special user requirements (e.g.
differing character sizes) but is time critical machine code.
code is for the ATMega 48/88/168/328 ICs. A PCB is available for
testing and / or production. The code can be ported to other ATMega AVR
ICs which have 512 bytes or more RAM, and a clock of 16-20 MHz.
When using the company licence (which allows as many copies as you need) you
will also require a registered copy of BASCOM to allow
sufficient Flash program memory for most projects, as the binary
include file for the TV output code is 2.5K, leaving only 1.5K of
available space for your program out of the 4K maximum space allowed in
the demo version of BASCOM.
The software and hardware is made by Eximia Projects.
Your order will be shipped from the UK, directly from the manufacturer.
You will receive a binary include file.
will also receive a free development board PCB. This board is used in
production and does not has an ISP connector. But it has a tested
processor and all other components. All you need is to connect 5V and a
TV and it will show a demo.

Support is included in the cost of
the development package. You can be assured that this support will
smooth your way to producing a product with a TV output - you will not
be left to struggle on your own.
Before purchasing the package you
might want to E-mail to check if the TV software will be compatible with
your planned product, for example if there are many interrupts running
or a heavy CPU load.
If you want to use a different Atmel AT Mega
IC to the one the software is designed for (AT Mega 48 / 88 / 168 /
328) the first step to take is to contact Eximia Projects and let me
know what your design requires. I can then let you know what extra
steps you will need to take (if any) to get the TV software to work with
any specific hardware. You can contact Graham Carnell at email@example.com
How to use BASCOM with the TV software module
The TV display is very simple to use from a programming point of view.
it runs entirely within the ATMega chip, it uses internal RAM to hold
the display data. This means that all you have to do to write to the
display is write bytes to the RAM which is allocated to the TV screen
