From f75f426dfae5190d3e637b247030d3a244968c2a Mon Sep 17 00:00:00 2001 From: Erik van der Zalm Date: Sun, 27 Nov 2011 21:12:55 +0100 Subject: [PATCH] Removed interrupt nesting in the stepper ISR. Add serial checkRx in stepper ISR. Copied HardwareSerial to MarlinSerial (Needed for checkRx). --- Marlin/Configuration.h | 2 +- Marlin/EEPROMwrite.h | 1 + Marlin/Marlin.h | 10 +- Marlin/Marlin.pde | 25 +- Marlin/MarlinSerial.cpp | 213 ++++++ Marlin/MarlinSerial.h | 66 ++ Marlin/Sd2Card.cpp | 1283 +++++++++++++++++++------------------ Marlin/SdBaseFile.cpp | 10 +- Marlin/SdBaseFile.h | 2 + Marlin/SdFatUtil.cpp | 4 +- Marlin/SdFatUtil.h | 92 +-- Marlin/motion_control.cpp | 6 +- Marlin/motion_control.h | 2 +- Marlin/planner.cpp | 6 +- Marlin/planner.h | 2 +- Marlin/stepper.cpp | 37 +- 16 files changed, 1007 insertions(+), 754 deletions(-) create mode 100644 Marlin/MarlinSerial.cpp create mode 100644 Marlin/MarlinSerial.h diff --git a/Marlin/Configuration.h b/Marlin/Configuration.h index 3a1983956..558044e28 100644 --- a/Marlin/Configuration.h +++ b/Marlin/Configuration.h @@ -232,7 +232,7 @@ const bool Z_ENDSTOPS_INVERTING = true; // set to true to invert the logic of th // minimum time in microseconds that a movement needs to take if the buffer is emptied.
