Merge pull request #373 from simark/sram
Compare address with I/O end address in _avr_set_ram
Compare address with I/O end address in _avr_set_ram
In _avr_set_ram, we check if the address is smaller than `MAX_IOs + 31`
to know if it is a register or SRAM location. In reality, many devices
have less I/Os than that, so the SRAM begins before this address.
As shown in issue #372, this causes watchpoints to not be triggered when
writing to an SRAM location that is smaller than `MAX_IOs + 31`. For
example, a global variable on an atmega328 gets placed at address 0x100,
which is less than `MAX_IOs + 31`.
Fix this by comparing the address to the `ioend` property of `avr`.

I've found that there is a maintainer who publishes SimAVR for Ubuntu here:
https://packages.ubuntu.com/bionic/simavr
Seems to be kept reasonably up-to-date (the latest there is 1.15 whereasy here on GitHub it is 1.16).
I know that maintainers do not always keep in contact with the software vendor so I would not be surprised to learn you were not aware of this. If you are okay with it though and consider it to be a legit enough source, I figure it's good to call that out in the README.

Setting a default wgm_op makes time timer run in normal mode witha size

Fix receiving after fifo overrun
After fifo overrun buffer_done remains less than buffer_len and
FD_SET(p->port[ti].s, &read_set) is not called. If firmware has nothing
to send, select always returns 0 and new data is never read even if
fifo buffer gets flushed.
This patch removes check for select timeout, so the remaining data in
buffer may go to fifo.

Correct x8 ADC mux modes
In all of the datasheets for ATmega44/88/168/328 devices that I've

and the temperature sensor is selected with MUX mode 1000.
modify avr_callback_sleep_raw() to mitigate sim time and wall clock time divergence
To avoid simulated time and wall clock time to diverge over time
this implementation tries to keep them in sync (roughly) by sleeping
for the time required to match the expected sleep deadline
in wall clock time.
The simulation will burst as fast as the host CPU will allow
until the simulated MCU sleeps, at which point avr_callback_sleep_raw()
sleeps for the time required to sync wall clock time with simulated MCU
time.

ssd1306: move display vertical and horizontal mirroring to OpenGL scene setup
The idea is that the display orientation related code belongs in the
board's implementation. Prior to this commit boards which mount the
display with a different orientation would end up mirroring the pixels
twice: once when reading them from the framebuffer and again in the
OpenGL scene rendering. As a sideeffect now reading pixels from the
vram array is simplified.
