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
