The pin may be filtered by an RC circuit to achieve a clean sine-wave s. For example, to convert a potentiometer setting to a number: END is terminated only by a hardware reset.


Approximately 50ua average current will be consumed. Here is an example DATA statement: It is advanced by 1 for each byte declared. The VAR usage options are as follows: PWM pin,duty,cycles Pin will be temporarily made an output while it microprocessadoress modulated. Defined and undefined data are declared as follows: The result will be written into variable. Undefined data is the mere allocation of data space, while not assigning values into the bytes of EEPROM to be done at run-time, instead.

Keep in mind that you may make alias names for the pin variables: In the above example assuming this was the first DATA statement in the program”table” becomes a constant symbol of value 0; “Here is a string Enviado por caetano flag Denunciar.

Duty is an 8-bit value which specifies the duty-cycle. Initially, the DATA location is set to 0.

The symbol name will be assigned a constant value as if via CON which is the current data pointer. The microprocessarores following ‘DATA’ is usually a list of bytes which can be constant expressions. Non-unique variables are in-whole or in-part derived from unique variables and get assigned within the unique-variable memory.

The CON syntax is as follows: Here are all the variable modifiers: NAP x Enter low-power mode for a short period.

For defining unique variables: Use Alt-M to see this. This allocation is automatic.

High-Z speakers may be driven with a coupling cap and a filter cap. Alt-M is a quick apositla to assess how much RAM you’ve used. Reset will end STOP.


The default on and off times are ms and 50ms. DATA statements are used to build data into unused memory. The compiler will always tell you when you have a conflict. Adjusting the pot causes the returned value to go up or down. Your data, on the other hand, builds from the start of memory towards the end.


The x values for NAP are as follows: STOP Execution is frozen, but low-power mode microproceswadores not entered.

The sum of program and data memory cannot exceed the 2K byte limit. Freq2 is optional and specifies a second frequency.

A digital-analog converter can be made by connecting the pin to a resistor which goes to a cap which goes to VSS. The pin may be filtered by an RC circuit to achieve a clean sine-waves. It may be necessary to place a series resistor to the pot to prevent a short from the high pin to VSS.

RCTIME pin,state,variable Pin will be placed in input mode and time will be measure in 2us units while pin is in ‘state’.

Milliseconds specifies how long to output the frequency s. Defined data is fully declared and known at compile time. This is handy for having a single declaration which gets accessed throughout your program.
