@geeksville eink TODO:
soonish:
DONE hook cdc acm device to debug output
DONE fix bootloader to use two buttons - remove bootloader hacks
DONE get second button working in app load
DONE use tp_ser_io as a button, it goes high when pressed unify eink display classes
fix display width and height
clean up eink drawing to not have the nasty timeout hack
measure current draws
DONE put eink to sleep when we think the screen is off
enable gps sleep mode
turn off txco on lora?
make screen.adjustBrightness() a nop on eink screens
later:
enable flash on qspi.
fix floating point SEGGER printf on nrf52 - see "new NMEA GPS pos"
add factory/power on self test
feedback to give:
* bootloader is finished
* the capacitive touch sensor works, though I'm not sure what use you are intending for it
* remove ipx connector for nfc, instead use two caps and loop traces on the back of the board as an antenna?
* the i2c RTC seems to talk fine on the i2c bus. However, I'm not sure of the utility of that part. Instead I'd be in favor of
the following:
* move BAT1 to power the GPS VBACKUP instead per page 6 of the Air530 datasheet. And remove the i2c RTC entirely.
* remove the cp2014 chip.
* I've made the serial flash chip work, but if you do a new spin of the board I recommend:
connect pin 3 and pin 7 of U4 to spare GPIOs on the processor (instead of their current connections),
This would allow using 4 bit wide interface mode to the serial flash - doubling the transfer speed! see example here:
https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/nrf52840_DK/hw_external_memory.html?cp=4_0_4_7_4
Once again - I'm glad you added that external flash chip.
* Power measurements
When powered by 4V battery
CPU on, lora radio RX mode, bluetooth enabled, GPS trying to lock. total draw 43mA
CPU on, lora radio RX mode, bluetooth enabled, GPS super low power sleep mode. Total draw 20mA
CPU on, lora radio TX mode, bluetooth enabled, GPS super low power sleep mode. Total draw 132mA
Note: power consumption while connected via BLE to a phone almost identical.
Note: eink display for all tests was in sleep mode most of the time. Current draw during the brief periods while the eink was being drawn was not
measured (but it was low).
Note: Turning off EINK PWR_ON produces no noticeable power savings over just putting the eink display into sleep mode.
