Scott Lahteine 15d68cb496 Pre-override of ST7920 delays before HAL.h 2018-07-26 23:33:18 -05:00
Andy Shaw 624986d423 Ensure ADC conversion is complete before reading (#11336) 
The current Marlin implementation relies on a timer interrupt to start the ADC conversion and read it. However in some circumstances the interrupt can be delayed resulting in insufficient time being available for the ADC conversion. This results in a bad reading and false temperature fluctuations. These changes make sure that the conversion is complete (by checking the ADC hardware via the HAL) before reading a value.

Chris Pepper 55f4744e54 [LPC176x] Endstop Interrupts Feature (#11202) 
Enable the endstop interrupts feature for LPC176x boards. Although Smoothieboard chose to use non-interrupt capable pins for their endstops, and this has been copied by clones, so they can't use it.

Eduardo José Tagle d3c02410a8 [2.0.x] Small assorted collection of fixes and improvements (#10911) 
* Misc fixes and improvements

- Get rid of most critical sections on the Serial port drivers for AVR and DUE. Proper usage of FIFOs should allow interrupts to stay enabled without harm to queuing and dequeuing.
  Also, with 8-bit indices (for AVR) and up to 32-bit indices (for ARM), there is no need to protect reads and writes to those indices.
- Simplify the XON/XOFF logic quite a bit. Much cleaner now (both for AVR and ARM)
- Prevent a race condition (edge case) that could happen when estimating the proper value for the stepper timer (by reading it) and writing the calculated value for the time to the next ISR by disabling interrupts in those critical and small sections of the code - The problem could lead to lost steps.
- Fix dual endstops not properly homing bug (maybe).

* Set position immediately when possible

etagle 0566badcef Add memory barrier, optimal interrupt on-off 
Disabling an ISR on ARM has 3 instructions of latency. A Memory barrier is REQUIRED to ensure proper and predictable disabling. Memory barriers are expensive, so avoid disabling if already disabled (See https://mcuoneclipse.com/2015/10/16/nvic-disabling-interrupts-on-arm-cortex-m-and-the-need-for-a-memory-barrier-instruction/)
