REVERSE <strong>Syntax</strong> reverse pin • Pin - is any expression, constant or variable that specifi es a pin to use. Supported • BA - Supported • BAN - Supported • BAP - Supported • BAP40 - Supported Commands Description REVERSE will switch the input/output direction of a pin. If the pin was an input it would reverse to an output. If the pin was an output it would reverse to an input. A pin’s state determines whether it can be read or set. To read a pin and determine if it has a high (1) or low (0) signal applied to it, the pin must be set to an input. A pin can only be set to high (1) or low (0) if the pin is in an output state. Schematic Connect an LED as shown below. You can substitute the resistor for anything from 330 ohms to 470 ohms. Example The program turns the LED on, using the High command which is an output command. Then the LED will turn off using the Reverse command which changes P0 from an output to an input. When P0 is an input the internal circuitry is disconnected and the pin can no longer supply the 5V need to illuminate the LED. Loop High p0 Pause 500 Reverse p0 Pause 500 Goto Loop P0 R1 390 D1 LED GND 174
SERIN <strong>Syntax</strong> serin rxpin{\fpin},baudmode,{plabel,}{timeout,tlabel,} [{modifi ers} InputData1, ..., {modifi ers} InputDataN] Commands • Rxpin - is a variable, constant or expression that specifi es the receive data pin. This pin will switch to input mode and remain in that state at the end of the command. • \fpin - is an optional variable, constant or expression that specifi es a pin for fl ow control (the “\” is required). Flow control is used primarily with PC COM ports and conforms to RS232 serial port specifi cations. The fl ow control pin will switch to output mode and remain in that state at the end of the command. • Baudmode - is a 32 bit variable, constant or expression that specifi es how fast to receive data and in what format. Several predefi ned baud modes are available, however custom modes are allowed. See the Baud Mode table for predefi ned modes. • Plabel - is an optional label. The program will jump to plabel if parity is used and there was a parity error. • Timeout - is an optional 32 bit variable, constant or expression that specifi es the time to wait for incoming data. The value is measured in 0.5 microsecond increments. If the data does not arrive within this time, the program will jump to tlabel. • Tlabel - is an optional label the program will jump to, if a timeout is specifi ed and has occurred. • InputData - is a list of variables or constants that tell SERIN what to do with incoming data. The incoming data can be formatted with optional input modifi ers. See the Modifi er section of this manual. Supported • BA - Supported • BAN - Supported • BAP - Supported • BAP40 - Supported Description The SERIN command is designed to work with the RS232 serial specifi cations. The command is bit banged, which means they are created in software running on the processor. When SERIN is run the processor can not do anything but receive data. RS232 is a simple communication format supported by the PC and is referred to as a COM port. The COM port can send and receive data simultaneously with each being a separate circuit that works in only one direction. Each circuit can function independently to transmit and receive data at the same time. This means the COM port is full duplex. The SERIN command is not capable of full duplex since it is software based. A 12 volt system was developed to work over long wire lengths and electrically noisy environments. The low state (0) is defi ned by +3 to +12 volts while a high state (1) is defi ned by a -3 to -12 volts. Modern computer equipment ignores the negative level and accepts a zero voltage level as a 1. This means circuits powered by 5V are capable of driving RS232 circuits directly, however, the overall range that the RS232 signal may be transmitted and received is dramatically reduced. 175
