Function didn't display negative calibration factors correctly.
Also added option to use the calibration factor without enabling the calibration menu to save some space.
This updates the GBC Gameshark functions to check the Chip ID before performing any other functions, which ensures a good connection with the Gameshark cartridge and prevents erroneous dumps or writes due to poor connection.
This adds full support for the Xplorer 64, including backup and writing of new firmware to the device. Firmware must be unscrambled (not dumped directly from the chips in a chip reader) in order to work with this program. Firmware dumped via the Sanni Cart Reader with this function work perfectly when written back.
This updates the N64 Gameshark function description, adds progress bars for the writing and verification functions, and updates the Chip ID function to report an unknown chip.
This completes the N64 Gameshark functions. It adds the command to enable CPLD address ranges of 0x1EEx_xxxx, 0x1EFx_xxxx, and 0x1ECx_xxxx which are necessary to program the SST 28LF040 eeprom. This also adds full support for the SST 28LF040 eeproms.
Unable to actually test this myself because I do not have a HW3 to test on. However, looking at the schematic, if the EEP switch is set to the off position then the pin will be floating and the result of the 1K resistor test will be random.
DS1307 does not seem to have the lost lostPower function. So the time does not get set on upload and needs to be set manually as described in the [wiki](https://github.com/sanni/cartreader/wiki/Real%E2%80%90Time-Clock#setting-the-time).
In Config.h set like this:
````
#define RTC_installed
//#define DS3231
#define DS1307
````
Connect "Tiny RTC I2C module" or similar to the SDA/SCL/VCC/GND pins.
The `setVoltage()` function should be called even when `ENABLE_VSELECT` is disabled because `ENABLE_3V3FIX` also uses it. There is no resource cost to do this as when both options are disabled the compiler will optimize this function out. This just "future proofs" the code so if that function ever does more it doesn't need updated everywhere. This applies to `setup_FlashVoltage()` as well.
The changes to OSCR.cpp are just for code formatting and additional comments to clarify this.

Lots of changes/additions.
Added:
* Firmware Updater support: Supports the Firmware Updater app (release to follow soon). Enabled by default, can be disabled in the config.
* 3.3V Fix (3V3FIX): Enable if you have stability issues when using 3.3V, works best with VSELECT. Disabled by default, can be enabled in the config.
* `DynamicClockSerial`: Class that extends and modifies HardwareSerial to be compatible with a dynamically changing clock speed. Used through the `ClockedSerial` object/variable.
* `OSCR.cpp` & `OSCR.h`: New files for storing globals. Only contains these new additions for now. More code cleanup to come.
Changed:
* Moved configuration flags to `Config.h` and documented them better.
* Removed `vselect()` function. Now uses `setVoltage()` with the params `VOLTS_SET_3V3` and `VOLTS_SET_5V`.
Known Issues:
* Rarely the LCD backlight turns white when using 3V3FIX. Resetting fixes it. Doesn't affect functionality/usability; it's just weird.
- fix a loop issue brought by yesterday's commit, when banks were increased/decreased and ROM dumped right after.
- screen is now refreshing fine after bank increase/decrease or forced rom size
- display the ROM size value to be set, before forcing it
Improved convenience :
- Tennokoe dumps are saved into a dedicated "./PCE/RAM/" folder
- "Reset" command was moved to the very last option of PCE menu
- Fixed the double button push when increasing/decreasing the bank index
- Forced ROM size can be set via defined variable
- Removed some repeated/unneeded function calls
- Add support for "Micro Machines 2 - Turbo Tournament (E)" and "Micro Machines - Military (E)"
- "cartridges size fix" section was re-ordered by detected values
Add support for :
- "16M / 32M Pocket Flash Card" : old flashcarts, respectively in black, and transparent purple cases. Since their flash chips are returning 0x204C value (4Mbits), you will need to manually select the wanted ROM size before dumping them.
- "NeoGeo USB Flash Masta 2 in 1" : contains 2x 16Mbits Fujitsu chips, now detected fine.
It seems the Arduino IDE picks the position of the first definition to
insert all auto-generated forward declarations. This fails to compile if
any of these generated forward declarations references a type included
later.
So, reorder the code a bit so the first definition happens strictly after
the last inclusion.
This code was removed as part of
a555f21 ("All: Resolve all compiler and linker warnings")
because it was filling a 1kB buffer which was never read from.
While I expect reading values from PINC should be invisible from the
cartridge's perspective, writing to PORTL, PORTF and PORTK is definitely
visible.
I have currently no way of testing if this code is required, so in doubt
restore the parts which have effects visible from the cartridge.
I am not sure why I changed some variables from 16 bit types to 8 bit types
when the warnings being resolved were only about signedness.
Fixes: a555f21 ("All: Resolve all compiler and linker warnings")
Also, make print_FatalError(*) independent from print_Error(*).
Also, factorise common parts of print_Error(*).
Frees 2336 bytes of program space and 5 bytes of global ram space.
IMPORTANT: with this change, the Adafruit clock generator becomes a hard
requirement to read and write gamecart eeproms.
This is a large patch, partly because JoyBus is used a lot:
- controller
- controller pak
- gamecart eeprom
and partly because of the further simplifications it allows.
Also, implement low-level bit shift functions in assembly in order to get
complete control of the timings: there can be just a few cycles of slack.
Also, use the time waiting for the input line to go high to pack received
bits into bytes on-the-fly, as there is now plenty of time.
This saves about 2080 bytes of program space, and 369 bytes of global ram
space.
More sizeof() use, avoiding high-level loops when a callee can do it
without the call overhead on every iteration, a bit of source code
factorisation, avoiding initializers for large variables.
These variables are set but never read. Removing them removes a non-trivial
amount of code, which I am not comfortable deleting: it contains knowledge
about cart data structure, even though it is currently not being used for
anything. So comment it out until someone who know this architecture better
comes around.
Frees 146 bytes of program space and 16 bytes of global ram space.
Also, remove dead error handling code: sd.exists internally opens the file
and returns the produced status, so myFile.open return value should be the
same.
Tagged with noreturn so the compiler knows about the effect of
forceReset=true.
Ideally, print_Error should lose its forceReset argument so that:
- print_Error never resets
- print_FatalError always resets (and hosts the code doing so)
so the compiler is more accurately aware of the execution flow.
Also, bypass sdBuffer when it was the directory copied to another buffer.
Also, factorise yet another pair of loops copying rom name.
This frees 59 bytes of global ram space.
Mainly, this removes a lot of the logic from selectMapping by reusing the
copy already present in getMapping. As a result, selectMapping is not
expected to be accessed from outside this module anymore.
Also, this factorises several smaller chunks of code found throughout the
module.
Also, get rid of a few easy globals along the way.
Also, move a bit more of NES-specific initialisation and menu display to
the NES.ino module.
This saves about 1490 bytes of code.
Replace switch blocks which produce one output with const tables.
Use functions instead of repeating code.
Move common initial and final statements outside of blocks.
Also, do not erase/flash second bank on dual-bank chips when the first one
had failures.
This saves about 520 bytes of code and increases ram use by 12 bytes.
It seems crc32EEP only exists because the actual number of bytes read from
file were not checked, hence falling back to smaller reads.
Instead, always read up to the full available buffer, adding to the CRC
only as many bytes as were actually read.
Also, move some related variables to local scope.
Overall, this saves about 50 bytes of code and 80 bytes of global ram.
In this codepath, there will be a second call just after displaying the
CRC, making this call redundant.
For completeness: In the alternate codepath, the next operation does a lot
of IO, so it makes sense to refresh the screen before printing the CRC.
This avoids code duplication between it and
convertPgm(const char* const [], byte)
for just 3 callers, when the callers can be easily updated to call the
latter.
Also, this resolves a warning about `count` being potentially used
uninitialised: when landing in the "Too many files" codepath.
With this simplification, the limit on the number of files is removed. It
is unclear whether that was intentional (maybe this was gating other
issues ?)?
