Keep in mind that micdoprocessadores may make alias names for the pin variables: The VAR usage options are as follows: The pin may be filtered by an RC circuit to achieve a clean sine-waves. The compiler will always tell you when you have a conflict.


The sum of program and data memory cannot exceed the 2K byte limit. Freq2 is optional and specifies a ce frequency. For example, to convert a potentiometer setting to a number: Here are all the variable modifiers: The resistor-cap junction will reflect the duty V during and after PWM.

Approximately 50ua average current will be consumed. 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 It is advanced by 1 for each byte declared.

Reset will end STOP. Defined data is fully declared and known at compile time. STOP Execution is frozen, but low-power mode is not entered.

Here is an example DATA statement: Enviado por caetano flag Denunciar. High-Z speakers may be driven with a coupling cap and a filter cap. When done, pin will be placed in input mode micriprocessadores allow the voltage to remain until another PWM is executed. A digital-analog converter can be made by connecting the pin to a resistor which goes to a cap which goes to VSS.

The result will be written into variable. The CON syntax is as follows: The pin may be filtered by an RC circuit to achieve a clean sine-wave s. The x values for NAP are as follows: Alt-M is a quick way to assess how much RAM you’ve used.

Use Alt-M to see this. This allows you to change programs while keeping data, assuming both programs apostjla the same stretch of memory as undefined DATA. RCTIME pin,state,variable Pin will be placed in input mode and time will be measure in 2us units while pin is in ‘state’.

NAP x Enter low-power mode for a short period. Enviado por caetano flag Denunciar. Defined and undefined data are declared as follows: Milliseconds specifies how long to output the frequency s. DATA statements are used to build data into unused memory.

The text following ‘DATA’ is usually a list of bytes which can be constant expressions. Your data, on the other hand, builds from the start of memory towards the end. Undefined data is the mere allocation of data space, while not assigning values microprocessavores the bytes of EEPROM to be done at run-time, instead.


Non-unique variables are in-whole or in-part derived from unique variables and get assigned within the unique-variable memory.

This is handy for having a single declaration which gets apostjla throughout your program. Adjusting the pot causes the returned value to apostkla up or down.

It may be necessary to place a series resistor to the pot to prevent a short from the high pin to VSS. The default on and off times are ms and 50ms. This allocation is automatic.

For defining unique variables: Initially, the DATA location is set to 0. Freq1 specifies the first frequency in 1Hz units Hz. Alt-M lets you see the result of this process. END is terminated only by a hardware reset. PWM pin,duty,cycles Apoxtila will be temporarily made an output while it is modulated.

Duty is an 8-bit value which specifies the duty-cycle.
