When reading or setting the value, the driver is expecting steps_t which is a axis scaled value.
This increases the memory footprint quite a bit. But now if you set 800mm/s2, you should get a similar value back.
Flash: +132 bytes
SRAM: 0 bytes
The read operation now returns the actual used value instead of the maximum allowed acceleration value.
Change in memory:
Flash: + 78 bytes
SRAM: 0 bytes
It looks like copying the RegisterRec into a local variable (as it has been here before)
seems to confuse the compiler which then refuses to optimize the calls.
With this simple tweak the code is actually 8B shorter than before (while retaining the saved ~170B of RAM)
This commit introduces a new set of registers 0x1e, 0x1f and 0x20 which allow reading and writing iRun current values for each axis/motor.
Please note the register contains raw TMC2130 iRun value which needs to be translated into mA to be understandable by people.
Translation table of iRun -> mA is present in tmc2130.cpp for now.
Several issues addressed in this PR:
- CutFilament tuning + error recovery
- introduce register 0x1d (cut filament selector iRun current level)
- optimize setting iRun and iHold currents in the FW
- CutFilament unit test fixed
- rename stall*guard to StallGuard (match name with the vendor)
- separate TMC2130 module from EEPROM (they do not need to know about each other at all)
- separate SGTHRS settings from motion - moved to globals like all other "global" parameters
- improved EEPROM storage for SGTHRS
This needs some investigation if it is really possible to push the Registers into PROGMEM. I think it should be possible, but the compiler is currently not collaborating.
It is not critical though as we have lots of free RAM at the moment (I can't believe I wrote this on an AVR project :) )
