WIP

Resources for working with Smart Response XE and custom code with CC1101 radio module.

Setup

• use ICSP on pogo-pins through (existing) holes in battery compartment to to do initial arduino bootloader programming (so you can use serial instead of ICSP)
• The arduino hardware-definition matches this
• Program the arduino bootloader with ICSP, then use serial to make it work more like regular arduino, set the programming port to serial 1
• Connect a CC1101 board (with little antenna) to SPI (MISO, MOSI, SCK, VCC, GND on ICSP test-pads) and GD0 (labeled CS_flash) & CSN pins (left pin of R34)
• Connect serial TX/RX of RS232 to connector for serial adapter and solder-bridge pins 3,4,5 on U6 trace.
• Drill hole in case to fit antanna, cut little bit out of fin inside to fit the CC1101 board
• Install SmartResponseXE and CC1101 libraries in arduino

arduino

• wireless bootloader it's kinda big & requires sacraficial XE, but might be good for some situations, and maybe I could do something with RTL-SDR, with a little work
• pager
• another pager
• spectrum analyzer
• BASIC Interpretor
• arduboy2 core
• arduboy2 core + Virus LQP-79 game

needs investigation

• A small board like this built-in might make it more arduino-like, and easier for non-tech (and tech) people to use.
• Need to work out how to use the SPI flash & CC1101 at same time (I think it's either/or right now)
• Need to see if I can get the built-in radio doing something useful.
• Figure out all the GPIO I can access and wire them to a port. It would be neat to be able to do i2c, etc. Some are easier to get at (like JTAG, speaker, and top-4 pogo pins)
• Work out programmer RESET. I needs a 0.1uF capacitor, and a little soldering
• Try to wire CC1101 into pogo board for less messy soldering? also maybe can use some easier pins (JTAG or speaker?)
• this bootloader can get it's sketch from external flash (liek the SPI flash on XE), which may help with a better wireless bootlader. This is also a way to support multiple "roms" in a selector menu.

Thanks

• pinout docs
• good forum thread
• Image-credit: @ce. Lots of great notes on putting it together, too.
• arduino lib is very useful.
• Detailed setup
• This has some good notes & setup for easier arduino
• this has notes about running arduboy on the XE
