Golang sp_set_config_stopbits Examples

Example #1

File: lsport.go Project: kezl/lsport

// SetParams sets the common port options: baudrate, bits and stopbits.
func SetParams(s *Conf, baud int, bits int, stopbits int) (int32, error) {
	var result int32 = SP_OK
	C.sp_set_config_baudrate(s.newConfig, C.int(baud))
	C.sp_set_config_bits(s.newConfig, C.int(bits))
	C.sp_set_config_parity(s.newConfig, SP_PARITY_NONE)
	C.sp_set_config_stopbits(s.newConfig, C.int(stopbits))
	result = C.sp_set_config(s.Port, s.newConfig)
	return result, checkResult(result)
}

Example #2

File: serial.go Project: arduino/arduino-create-agent

// this operation. Call p.ApplyConfig() to apply the change.
