/**
|
|
* rev B 30 DEC 2016
|
|
*
|
|
* The original version of this file did NOT result in a useful program because:
|
|
* 1. The pin numbers assumed that the "#define AT90USBxx_TEENSYPP_ASSIGNMENTS" line
|
|
* in FASTIO.h was commented out. There wasn't an Arduino IDE 1.6.x extension/package
|
|
* that supported this pin map so the latest Marlin wouldn't compile.
|
|
* 2. The silkscreen for the four end stops don't agree with the schematic. Activating
|
|
* the X endstop would tell the software that the Y endstop just went active.
|
|
* 3. The thermistor inputs also had heater names assigned to them. The result was
|
|
* thermistor inputs that were set to digital outputs.
|
|
*
|
|
* Rev B corrects the above problems by:
|
|
* 1. The "Marlin_AT90USB" extension/package was developed. This extension enables the
|
|
* latest Marlin software to compile using Arduino IDE 1.6.x and 1.80.
|
|
* 2. The endstop pin numbers in this file were changed to match the silkscreen. This
|
|
* makes it a little confusing when trying to correlate the schematic with the pin
|
|
* numbers used in this file.
|
|
* 3. The offending heater names were deleted.
|
|
*
|
|
* To create a useable image for Teensylu do the following:
|
|
* a) Install the Marlin_AT90USB extension with either of the following methods:
|
|
* Automatic - paste this URL into preferences and then use Boards manager
|
|
* https://rawgit.com/Bob-the-Kuhn/Marlin_AT90USB/master/package_MARLIN_AT90USB_index.json
|
|
* Manual:
|
|
* 1. Copy the following URL into Go to "https://github.com/Bob-the-Kuhn/Marlin_AT90USB",
|
|
* click on the "Clone or Download" button and then click on "Download ZIP" button.
|
|
* 2. Unzip the file, find the "Marlin_AT90USB" directory and then copy it to the
|
|
* hardware directory in Arduino. The Arduino hardware directory will probably be
|
|
* located in a path similar to this: C:\Program Files (x86)\Arduino\hardware
|
|
* b) Connect the USBtinyISP to the board.
|
|
* c) In the Arduino IDE select the "AT90USB1286_STANDARD" board in the of the "Marlin_AT90USB"
|
|
* section and select the "USBtinyISP" programmer.
|
|
* d) In the Arduino IDE click on "burn bootloader". Don't worry about the "verify
|
|
* failed at 1F000" error message.
|
|
* e) The USBtinyISP programmer is no longer needed. Remove it.
|
|
* f) In FASTIO.h comment out the "#define AT90USBxx_TEENSYPP_ASSIGNMENTS" line.
|
|
* g) To upload a sketch do the following:
|
|
* 1. remove the jumper
|
|
* 2. press reset
|
|
* 3. click on the "upload" button in the Arduino IDE
|
|
* 4. wait until the upload finishes (less than a minute)
|
|
* 5. put the jumper back on
|
|
* 6. press the reset button
|
|
*
|
|
*
|
|
* NOTE - the "Marlin_AT90USB" pin maps make PWM0A available rather than the usual PWM1C.
|
|
* These PWMs share the same physical pin. Marlin uses TIMER1 to generate
|
|
* interrupts and sets it up such that PWM1A, PWM1B & PWM1C can't be used.

/**
|
|
* SILKSCREEN ERROR
|
|
*
|
|
* The silkscreen for the endstops do NOT match the schematic. The silkscreen SHOULD
|
|
* read (from left to right) X-STOP, Y-STOP, Z-STOP & E-STOP. The silkscreen actually
|
|
* reads E-STOP, X-STOP, Y-STOP & Z-STOP.
|
|
*
|
|
* The pin assignments in this file match the silkscreen.
