Changelog

2017-08-12

• TX_SEND timer period changed to 1874. This makes the reporting frequency exactly 100 Hz (not taking clock tolerance into account)
• Added a serial command to clear any fault flag. Useful when calibrating the controller parameters
• Holding the reset pin low before powering the board puts the microcontroller into bootloader mode. You won't have to worry about the three second timeout window anymore *V1.1 board and schematic files with fiducials and test points for pogo pins instead of a programming connectos are available.

2017-05-24

• Fixed motor stutter every third of a second
• Fixed serial communications bug that froze the status reporting
• Made status reporting frequency exactly 100 Hz, to help with plotting and tunning
• Increased maximum following error value to 32000
• User can now switch between current or PWM output for status reporting

Thanks to Patrick Dussud for all the help
