BRANCHING
|
     |
IF . . .THEN |
Compare and conditionally branch. |
|
|
BRANCH |
Branch to address specified by offset. |
|
|
GOTO |
Branch to address. |
|
|
GOSUB |
Branch to subroutine at address. |
|
|
RETURN |
Return from subroutine. |
LOOPING
|
|
|
FOR . . . NEXT |
Establish a FOR - NEXT loop. |
NUMERICS
|
|
|
LOOKUP |
Lookup data specified by offset and store in variable.
This instruction provides a means to make a lookup table. |
|
|
LOOKDOWN |
Find target's match number (0-N) and store in variable. |
|
|
RANDOM |
Generate a pseudo-random number. |
DIGITAL I/O
|
|
|
INPUT |
Make pin an input. |
|
|
OUTPUT |
Make pin an output. |
|
|
REVERSE |
If pin is an output, make it an input. If pin is an
input, make it an output. |
|
|
LOW |
Make pin output low. |
|
|
HIGH |
Make pin output high. |
|
|
TOGGLE |
Make pin an output and toggle state. |
|
|
PULSIN |
Measure an input pulse. |
|
|
PULSOUT |
Output a timed pulse by inverting a pin for some time. |
|
|
BUTTON |
Debounce button, perform auto-repeat, and branch to
address if button is in target state. |
|
|
COUNT |
Count cycles on a pin for a given amount of time (0
to 125 kHz, assuming 50/50 duty cycle). |
|
|
XOUT |
Generate X-10 powerline control codes. For use with
X-10 lamp and appliance control modules. |
ASYNCHRONOUS SERIAL
I/O
|
|
|
SERIN |
Serial input with optional qualifiers and variables
for storage of received data. On the BS1-IC, baud rates
of 300, 600, 1200, and 2400 are possible. On the BS2-IC,
any baud rate (up to 50k baud) is possible. Also, the BS2-IC
has a serial input time-out function. |
|
|
SEROUT |
Send data serially. On the BS1-IC, data is sent at 300,
600, 1200, or 2400 baud. On the BS2-IC, data is sent at
any baud rate (up to 50k baud). |
SYNCHRONOUS SERIAL
I/O
|
|
|
SHIFTIN |
Shift bits in from parallel-to-serial shift register. |
|
|
SHIFTOUT |
Shift bits out to serial-to-parallel shift register. |
ANALOGUE I/O
|
|
|
PWM |
Output PWM, then return pin to input. This can be used
to output analogue voltages (0 to 5 V) using a capacitor
and resistor. |
|
|
RCTIME |
Measure an RC charge/discharge time. Can be used to
measure potentiometers (faster than POT on BS1-IC). |
SOUND
|
|
|
FREQOUT |
Generate one or two sine waves of specified frequencies
(each from 0 to 32767 Hz). |
|
|
DTMFOUT |
Generate DTMF telephone tones. |
EEPROM ACCESS
|
|
|
DATA |
Store data in EEPROM before downloading BASIC program. |
|
|
READ |
Read EEPROM byte into variable. |
|
|
WRITE |
Write byte into EEPROM. |
TIME
|
|
|
PAUSE |
Pause execution for 0 to 65536 milliseconds. |
POWER CONTROL
|
|
|
NAP |
Nap for a short period. Power consumption is reduced. |
|
|
SLEEP |
Sleep for 1 to 65535 seconds. Power consumption is reduced
to 20 µA (BS1-IC) or 50 µA (BS2-IC). |
|
|
END |
Sleep until the power cycles or the PC connects. Power
consumption is the same as SLEEP instruction. |
PROGRAM DEBUGGING
|
|
|
DEBUG |
Sends variables to PC for viewing. |
