I was thinking about new qi-avt2 features, specially power consumption and
SDRAM memory size.
1. The current design qi-avt2 use a keyboard that use a whole layer, We will
use this space if we use a capacitive keyboard with a cypress controller, In
the past we use , with our ARM board and we program the cypress chip with
the processor GPIOs. Whit this, we have enough space to place another SDRAM
chip on qi-avt2, and we will have up to 128MB of SDRAM, enough for many
2. I prefer use a light sensor for controlling the LCD brightness and detect
if the device is close.
3. I was thinking in the possible use of a FPGA in the design, I think that
this FPGA would provide some peripherals like PWMs, for servo controlling,
There are an open project that we can use with it . Or drive an analog
acquisition card for experiments like
