lcdseg.setup(bias, duty, vlcd, com_number, fresh_rate, com_mark, seg_mark)#

Initialize the lcdseg library

Parameters

Incoming Value Type	Explanation
int	bias value, usually 1/3 bias, corresponding lcdseg.BIAS_ONETHIRD
int	duty value, usually 1/4 duty, corresponding lcdseg.DUTY_ONEFOURTH
int	Voltage, unit 100mV, for example, 2.7v write 27. air103 supported values are 27/29/31/33
int	COM The number of feet, depending on the specific module, Air103 supports 1-4
int	refresh rate, typically 60, corresponding 60HZ
int	COM Enabled or not mask, the default is 0xFF, all enabled. If only COM0/COM1 is enabled, then 0x03
int	seg The mask of whether to enable or not, the default is 0xFFFFFFFF, that is, all are enabled. If only the first 16 are enabled, 0xFFFF

Return Value

return value type	explanation
bool	Returns true on success, otherwise false

Examples
