With this a TS-I tip is usable with a small netbook 19 V / 30 W PSU with
power limit set to 40 W (38.9 W is reported during the heating up
stage). Without this the device just reboots on attempt to turn on the
heater (unless the power limit is set to 10 or even 5 W).
This code doesn't affect maximum power available and allows up to 73 W
when a beefy 24 V / 96 W PSU is used.
Should be useful for all models, not just TS100.
The fixed comments are based on calculations, not measurements!
Fixes#693.
This radically slows down auto-incrementing (when the change button is
kept pressed) of values when user reaches the maximum (last) allowed
option. The scrollbar thumb is blinking to indicate to the user that the
next keypress will wraparound (unless this value was already active
prior to entering menu).
Fixes#536.
The code assumes that whenever scheduler is running I2CSemaphore is
available. Initialising it in a task might lead to race conditions and
is also not happening at all if the task is disabled (for debugging or
due to lack of need for a particular usecase).
The race condition can't happen with the current code though, as GUI
task has lower priority than the MOV task, and they're the only tasks
that currently use I2C. However, this might change in the future with
the code refactoring or introduction of new features.
This patch makes allocating special pages automatic and flexible,
allowing flash size and application start offset specification with
linker command line arguments. It should allow easier porting to
different targets and experimentation without adding code complexity.
Many original STM32F103x8 chips have fully functional 128 kiB flash and
so this additional space might come useful for experimentation,
additional optional features etc. Tested on v2.51A board, including
writing and verifying 128 kiB of random data.
Make variables are added to control that, so to build for the full
undocumented flash size and dapboot configured to start the app from 8
kiB offset one can run:
make flash_size=128k bootldr_size=0x2000
