Data Sheet

Set starting speed
Command 0xE5
Format 32-bit write
Data
starting speed, unsigned 32-bit
• Range: 0 to 500,000,000
• Units: microsteps per 10,000 s
ticcmd ticcmd --starting-speed NUM
Arduino lib tic.setStartingSpeed(uint32_t speed)
This command temporarily sets the Tic’s starting speed in units of steps per 10,000 seconds. This is
the maximum speed at which instant acceleration and deceleration are allowed; see Section 5.1 for
more information. The provided value will override the corresponding setting from the Tic’s non-volatile
memory until the next “reset” (or “reinitialize”) command or full microcontroller reset.
Set max acceleration
Command 0xEA
Format 32-bit write
Data
max accel, unsigned 32-bit
• Range: 100 to 2,147,483,647 = 0x64 to 0x7FFF FFFF
• Units: microsteps per 100 s²
ticcmd ticcmd --max-accel NUM
Arduino lib tic.setMaxAccel(uint32_t accel)
This command temporarily sets the Tic’s maximum allowed motor acceleration in units of steps per
second per 100 seconds. The provided value will override the corresponding setting from the Tic’s
non-volatile memory until the next “reset” (or “reinitialize”) command or full microcontroller reset.
If the provided value is between 0 and 99, it is treated as 100.
This command does not affect the max deceleration, even if the “Use max acceleration limit for
deceleration” checkbox in the Tic Control Center is checked. See the set max deceleration
command.
