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. */ #if !defined(__AVR_AT90USB1286__) && !defined(__AVR_AT90USB1286P__) #error "Oops!
