@geeksville eink TODO:
confirm that watchdog reset (i.e. all pins now become inputs) won't cause the board to power down when we are not connected to USB
(I bet it will). If this happens recommended fix is to add an external pullup on PWR_ON GPIO.
soonish:
hook cdc acm device to debug output
fix bootloader to use two buttons - remove bootloader hacks
fix battery voltage sensing
fix floating point SEGGER printf on nrf52 - see "new NMEA GPS pos"
get second button working in app load
if battery falls too low deassert PWR_ON (to force board to shutdown)
fix display width and height
clean up eink drawing to not have the nasty timeout hack
measure current draws
put eink to sleep when we think the screen is off
enable flash on spi0, share chip selects on spi1.
https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Fspi.html enable reset as a button in
bootloader fix battery pin usage drive TCXO DIO3 enable high whenever we want the clock use PIN_GPS_WAKE to sleep the GPS use
tp_ser_io as a button, it goes high when pressed unify eink display classes
make screen.adjustBrightness() a nop on eink screens
enable gps sleep mode
use new flash chip

fix floating point SEGGER printf on nrf52 - see "new NMEA GPS pos"
add factory/power on self test
use tp_ser_io as a button, it goes high when pressed unify eink display classes
feedback to give:
remove ipx connector for nfc, instead use two caps and loop traces on the back of the board as an antenna?
