This is handy for having a single declaration which gets accessed throughout your program. Enviado por caetano flag Denunciar.

Reset will end STOP. This allows you to change programs while keeping data, assuming both programs defined the same stretch of memory as undefined DATA. Use Alt-M to see this. The sum of program and data memory cannot exceed the 2K byte limit. STOP Execution is frozen, but low-power mode is not entered. Defined and undefined data are declared as follows: Freq1 specifies the first frequency in 1Hz units Hz.

Freq2 is optional and specifies a second frequency.

Duty is an 8-bit value which specifies the duty-cycle. The pin may be filtered by an RC circuit to achieve a clean sine-waves.


The pin may be filtered by an RC circuit to achieve a clean sine-wave s. NAP x Enter low-power mode for a short period. Alt-M is a quick way to assess how much RAM you’ve used. Keep in mind that you may make alias names for the pin variables: The compiler will always tell you when you have a conflict. The apowtila values for NAP are as follows: The VAR usage options are as follows: Your data, on the other hand, builds from the start of memory towards the end.

Adjusting the pot causes the returned value to go up or down.

Approximately 50ua average current will be imcroprocessadores. The symbol name will be assigned a constant value as if via CON which is the current data pointer. The resistor-cap junction will reflect the duty V during and after PWM.

Here are all the variable modifiers: The text following ‘DATA’ is usually a list of bytes which can be constant expressions. 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 RCTIME pin,state,variable Pin will be placed in input mode and time will be measure in 2us units while pin is in ‘state’.


When done, pin will be placed in input mode to allow the voltage to remain until another PWM is executed. This allocation is automatic. apoostila


Milliseconds specifies how long to output the frequency s. DATA statements are used to build data into unused memory. Enviado por caetano flag Denunciar. For defining unique variables: It may be necessary to place a series resistor to the pot to prevent a short from the high pin to VSS. END is terminated only by a hardware reset. A digital-analog converter can be made by connecting the pin to a resistor which goes to a cap which goes to VSS.

Here is an example DATA statement: High-Z speakers may be driven with a coupling cap and a filter cap. It is advanced by 1 for each byte declared.

The result will be written into variable.
