Description
First published version
Formula for calculation of sine wave look-up table corrected (section 5.11.2, page 13
and section 7.1, page 27).
load_scale outputs added at pinning table and register mapping
(section 9, page 29 ff. & section 6.2, page 15 ff.)
Detail tables for registers with complex content, added some missing register bits
formula for calculation of sine wave look-up table corrected (section 5.11.2, page 13)
and calculation of look-up table with offset added, corrected acceleration formula
Pin F4 in Table 2: TMC457-BC Pin Out, page 32 corrected (n.c. instead of ground)
Reference Switch table corrected (Reference Switch Configuration Register Set)
Changed documentation for Version 1.02 of TMC457:
Added bow restrictions, corrected formula for bow value
(Bernhard Dwersteg 40
Improved some descriptions
Pin G3 (75) explicitly marked as n.c. / F1 is input / Corrected pinning table according
names in Fig.1
C4 is GND, new method to disable JTAG by tying L10 and L12 to GND
C4 is a +1V5 (correct in pinning table, but comment in history 1.14 needed adaption)
V1.02 of TMC457: linear ramp failure when AMAX<128 and AMAX/=DMAX
Added known bugs section
Documented wrong stop switch behavior, corrected in V1.04 of TMC457
Added vector encoder registers (venc...)
Attention: VENC functions are only available starting from V1.02 of TMC457!
Register PID_DV_CPU was removed; register bits current_scale and outputs
LOAD_SCALE were removed,
Actual TMC249 stallguard value can be read now
Encoder constant can now be scaled in 1/10000 steps (enable via bit 13 of
enc_mode)
enc_clr_mode register renamed to enc_mode
th
birthday version!)
