EmStat4 firmware

1.6.01

Download Version 1.6.01

  • Added format specifiers for f-strings

  • Removed limitation on array index nesting

  • Conditional blocks (if, loop, etc.) can now take string operands

  • Added commands:

  • display_filebrowse to display an interactive file browser on the screen

  • droplet_detect_loop to enable droplet detection without additional hardware

  • Added string handling and parsing (str_find, str_length, str_parse_float, str_parse_int)

  • Added float_to_int_round

  • Added optional arguments:

  • Added optional argument keep_on to specify which electrode remains connected on cell_off.

  • Added optional argument avg_cnt to specify the amount of samples averaged

  • Added optional argument font_size support to display_scroll_get

  • Added VT_POTENTIAL_BIPOT variable type

  • The timer used by command timer_get optional argument time is no longer reset when running MethodSCRIPT, only at device startup and with timer_start

  • Reduced HW sync wait time

  • Improved EIS autoranging for scans from low to high frequency

  • Removed extra autoranging step at the start of an EIS scan to make behavior more predictable. meas_loop_eis will now always start at the selected range. This allows a meas_loop_eis autoranging step to be added before the main EIS measurement, which offers more control.
