Question on focus of the Hydra
T&E Engineer
Posts: 1,396
I have been using Parallax products for about a year and a half now starting with a BOEBOT (BS2 microcontroller hobby projects mainly) and then on to the SX-28 (SX/B)·with a Profesional Development Board (PDB). Last July I bought the Propeller Stick to try it out. However, learning SPIN was a bit tricky to follow and forget Assembly as I have not quite learned it for the SX-28 nor Propellor. I tried for a couple of months and lost interest. I would like to get back to my hobby projects again and perhaps even get involved on game writing using the Hydra.
When I heard of the Hydra, I was excited but concerned about the difficulty level involved to write games in SPIN and Assembler. I recently read that a TINY Basic was out (knowing it would not do much - but felt more comfortable with this). I later read that another BASIC was in the works for Hydra from Andre. If this is the case, I would love to use the Hydra as my comfort level has gone up.
What is the primary focus behind the Hydra? What can users expect to do with it? Is is strictly game writing? If so, that is cool and I would love to get involved. However, the introduction on the Parallax website for the Hydra sounds encouraging as anyone with some BASIC programing or similar language writing experience should be ok with the Hydra.
Can someone comment on this?
Thanks again.

The biggest difference is the manual. The Hydra manual, in addition to going into detail on the in's and out's of the chip itself, discusses each of the types of I/O (keyboard, mouse, video, network, game controller) in detail and discusses graphics, particularly from the game creation standpoint, in depth. The included CD has a great many sample game programs which can be used as is or used as the basis for some other game. Some of them really push the capabilities of the Propeller chip.
With the exception of those that use the game controllers, most of the software on the CD can be easily adapted to the Demo Board or any other Propeller setup with a TV video and PS/2 keyboard/mouse.
I've been working on getting the basic fully functional . Now that they released the asset management software , I have a plan of what to do to get it to save and load . There is a version that Mike Green wrote in spin (femento basic) that will work on the hydra. If you look at the propeller forum you can download a copy. There are cheaper ways to learn how to program the propeller than the hydra, but once you start reading Andre's book you'll know why you want him on your side ( I know you can just buy the book,but to me the extra money is worth it to be on the same playing field).I really believe that we have only seen the tip of the iceberg of what Andre' has up his sleeve for the hydra. I hope at least I answered some of your questions.

Get the hydra, I guarantee I can teach you to write games for it. Also, in addition to what mike mentioned about the similarities of the hydra and demo board, they are both a propeller chip, the hydra has many more interfaces including, the game ports, expansion port, RJ11 port for networking (serial bit banging). But, the most important of these is the expansion port which lets you make add on boards, plug them into the system. They can be as simple as game cards with EEPROMS on them, or add on processors, or SRAM (which is coming out soon).
But, the HYDRA is a complete game dev/propeller learning/hacking edutainment package. If you can survive reading all 800 pages of the book, you will definitely be able to write games on the hydra in SPIN and have a good grasp on how to write kernal level graphics engines in ASM.

Thanks again.

but the book is EXCELLENT
Andre, excellent writeup on sprites. Reminded me of programming my Atari 400XL YEARS ago!

I am very much looking forward to all of the wonderfull things that AndreL and other Hydra owners have been raving about.
I don't have a SVGA screen nearby (NTSC TV video and laptop only) - hopefully this will be ok.
Anyway, I am excited and have 2nd day UPS shipping.
Thanks to all for your enthusiasm.

Thanks again for the good words of excitement!
