Tome GS Specs

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.

  1. What software are you using to develop/compile the firmware?

  2. Would you be willing, once your finished, to make these devices to sell? i would be really interested in one.

    I 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.

    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.
