MICROPROCESSADORES

NAP x Enter low-power mode for a short period. Freq1 specifies the first frequency in microproceesadores units Hz. The pin may be filtered by an RC circuit to achieve a clean sine-wave s.

It is advanced by 1 for each byte declared. High-Z speakers may be driven with a coupling cap and a filter cap. A digital-analog converter can be made by connecting the pin to a resistor which goes to a cap which goes to VSS.

This is handy for having a single declaration dee gets accessed throughout your program. The VAR usage options are as follows: The resistor-cap junction will reflect the duty V during and after PWM. Alt-M is a quick way to assess how much RAM you’ve used. The x values for NAP are as follows: Adjusting the pot causes the returned value to go up or down. This allows you to change programs while keeping data, assuming both programs defined the same stretch of memory as undefined DATA.

Defined data is fully declared and known at compile time. Defined and undefined data are declared as follows: The sum of program and data memory cannot exceed the 2K byte limit. Use Alt-M to see this.

For defining unique variables: Here are all the variable modifiers: Reset will end STOP. 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 DATA statements are used to build data into unused memory.

Milliseconds specifies how long to output the microprocessadorres s.

Here is an example DATA statement: Approximately 50ua average current will be consumed. The text following ‘DATA’ is usually a list of bytes which can be constant expressions.

Alt-M lets you see the result of this process. Your data, on the other hand, builds from the start of memory towards the end. STOP Execution is frozen, but low-power mode is not entered.

The result will be written into variable.

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.

Keep in mind that you may make alias names for the pin variables: PWM pin,duty,cycles Pin will be temporarily made an output while it is modulated. Enviado por caetano flag Denunciar. END is terminated only by a hardware reset.

This allocation is automatic. The CON syntax is as follows: The default on and off times are ms and 50ms.
