A few people have asked about the specs of the current and planned devices. Later I will put project info and progress on the sidebar.
Current Device Specs:
cpu: at91sam7s256
speed: 55mhz
ram: 64k
flash: 256k
storage: minisd(4gb maybe HC) and 32kb eeprom
display: siemens s65 16bit color lcd
communication: bluetooth, usb, serial
audio: sterio using two pwm channels
power: 850mah li-ion battery, 500mah charger
New Device Specs:
cpu: at91sam7s256
speed: 55mhz
ram: 64k
flash: 512k
storage: minisd(4gb maybe HC) and 32kb eeprom
display: nokia 6610 12bit color lcd, adjustable backlight using pwm
communication: zigbee(MRF24J40MA), usb, serial, jtag(allow debug)
audio: sterio using two pwm channels, 3.5mm headphone, internal speaker
power: 850mah li-ion battery, 500mah charger
I might add a small expansion port with analog, digital and power pins.
The best thing about my design is that you don't have to reprogram the device every time you want to play a new game since they can be dynamically loaded from the minisd and execute in ram. The firmware will handle all the dirty work while and provide a simple interface to the hardware. The zigbee module can be used to communicate with other TGS's or other project utilizing zigbee communication. For example I'm building a quadruped robot and plan to control and monitor it with this device.

What software are you using to develop/compile the firmware?
ReplyDeleteWould you be willing, once your finished, to make these devices to sell? i would be really interested in one.

ReplyDeleteI use winarm to develop the code and Atmel provides a program called sam-ba which allows me to program the system over usb. When I finish the redesign jtag and serial can be used too.
@steven
I would like to do a small run of 25 units at first and if that goes well more would be made. If people are interested let me know.
Awesome game console on your YouTube channel!
DeleteI'd like to get started with microprocessor and microcontrollers so could you please answer my questions?
1. What is the basic working of your system
2. What hardware/software would I need to build a system which can render graphics(optionally handle input), which makes use of microprocessor, from scratch.
3. What were your learning sources, and what do you recommend for beginners to start out with?
4. Would you recommend using a development board, why (not)?
If you had financial problems, then it is time for you to smile. You only need to contact Mr. Benjamin with the amount you wish to borrow at the low rate of 2% ROI and the payment period that suits you and you will have your loan within three working days. I just benefited for the sixth time a loan of 700 thousand dollars for a period of 180 months with the possibility of paying before the expiration date. Mr Benjamin has been helping me with the loan.Make contact with him and you will see that he is a very honest man with a good heart.His email is 247officedept@gmail.com and his WhatApp phone number is + 1-989-394-3740 .
