void ser485Tx(void);
void ser485Rx(void);
Enables the RS-485 transmitter. Transmitted data get echo'ed back into the receive data buffer. These
echo'ed data could be used to know when to disable the transmitter by using one of the following
methods:
serMode() must be executed before running this function.
Disables the RS-485 transmitter. This puts the LP3500 in listen mode, which allows it to receive data
from the RS-485 interface. serMode() must be executed before running this function.
Byte mode—disable the transmitter after the same byte that is transmitted is detected in the receive
Block data mode—disable the transmitter after the same number of bytes transmitted is detected in the

receive data buffer.
NOTE: The RS-485 transceiver used on the LP3500 is only capable of supporting a max-
imum baud rate of 64,000 bits/s. The baud rate is set by the Dynamic C
macro. For example, add the following line on the
Options > Project Options
_485BAUD=57600
to set a baud rate of 57,600 bits/s, then click
