a5150c83a2 [2.0.x] Multiple updates to STM32F1 HAL (#8733)
* STM32F1 HAL

Adding files for STM32F1 HAL based on libmaple/stm32duino core.
Current persistent_store uses cardreader changes to be sent in separate
commit, but could be changed to use i2c eeprom.
There is another persistent_store implementation that uses the MCU flash memory
to emulate eeprom
Adding readme with some information about the stm32 HAL.

* Switch to Timer4 to avoid a hard reset on STM32F103C6 boards

On bluepill STM32F103C6 boards, using Timer5 results in a error() vector call. Switch to 4 since these are both general purpose, 16 bit timers.

* Add support for EEPROM emulation using Flash

Some low end machines doe not have EEPROM support. Simulate it using the last two pages of flash. Flash does not allow rewrite between erases, so skip writing the working version if that's enabled.

* Basic Pins for a malyan M200

This is a work in progress to go hand in hand with the STM32 work.

* Add support for ADC with DMA. This work has exposed a problem with the pin enumerations in STM boards vs what marlin expects (i.e, try defining PA0 as a temp pin). The hack can be removed with we go to fastio completely. To see this work, set something in adc_pins to a value like PA0 and connect your pullup resistor'd thermistor.

* Missing file - change HAL_adc_init to actually do something

We have an actual ADC init function now.

* Remove pinmode hack

Remove the pin mode hack that I was using to init PA0.

Updated Readme.md

* Several changes to timers and GPIO

Faster GPIO, and faster timer functions by accesing registers and
libmaple.
Still more changes pending for the Timer's code to skip using the
HardwareTimer class altogether.

Switch all enums to be within #defines

This change allows a user to have, for instance, TEMP_4 and TEMP_BED definied but nothing else. The enums which are not defined move "out", allowing the first ones to take the slots in the enum, and since the array is sized on ADC_PIN_COUNT, we always have the right size data and in order.

* Update Malyan M200 pins

Update Malyan M200 pins with correct fan values.

* Test all pins on actual hardware, update definitions

Some of the pin definitions were from knowlege base/pdfs. Now they've been tested against actual hardware. This should be very close to final.

* Update HAL_timers_Stm32f1.cpp

* Add sample configurations for Malyan M200

Add sample configuration for Malyan M200 without bed leveling, and move fan to auto cool E0 since this printer by default has only one fan.


Choose the timer based on MCU defintion. Timer5 is not valid on C8/CB class boards, so use Timer4 for the step timer.


readme.md update

* Updates to timers, and some stm32 boards definitiions

* Correct pin toggle macro.

* Remove duplicated Malyan M200 entry from pins.h

* Update configuration_store.cpp

* Formatting, indentation

* Formatting in HAL_Stm32f1.cpp

02aa93a6ad Fix Watchdog time out during long lasting DELTA moves
During long lasting moves of a delta machine neither the temperatures are maintained nor buttons checked nor ... .
The fix is to call 'manage_heater()' and 'idle()' every now and then in the loop where the move is segmented. 
The code is abot the same as in G2_G3 wher we had the same problem with too large circles lasting too long.

a61127a421 [2.0.x] tool change bad behaviours
This will solve 2 issues on tool change.
1) when no home is done ("no_move" is set) tool change should never move X & Y because... I don't know where I am...only Z should be adjusted to avoid bed collision if other nozzle is lower than current.
Since no move no bed level matrix should be applied
2) When SWITCHING_NOZZLE is enabled and system is homed there are two movements to go to destination, but first can move Z to older position and then crash on the bed

[2.0] No retroactive adjustment with M851 Z
2017-11-18 04:49:53 -06:00
Scott Lahteine
3bba7d60f3 No retroactive changes with M851 Z
If using babystep to adjust the Z probe offset, the axis will move and the mesh will be updated at the same time, causing a doubling of the Z offset over the rest of the print.

To correct for this, the current Z position would need to be modified in the opposite direction, canceling out the additional Z offset added to the mesh. This would be confusing to users, and moreover it would not be accurate without also taking the current Z fade level and current Z height into account.

It might make sense to change the mesh in the case where no babystepping is taking place, but this could be considered an undesirable side-effect of changing the `zprobe_zoffset`.

One way to remedy this would be to return to storing the mesh with `zprobe_zoffset` included, then subtracting `zprobe_zoffset` from the returned Z value. Thus, a babystep moving the Z axis up 1mm would subtract 1 from `zprobe_zoffset` while adding 1 to all mesh Z values.

Without including the `zprobe_zoffset` in the `z_values` there is no safe way to alter the mesh in conjunction with babystepping, although it's fine without it.
