The CON syntax is as follows: Alt-M is a quick way to assess how much RAM you’ve used. For example, to convert a potentiometer setting to a number: Adjusting the pot causes the returned value to go up or down. The VAR usage options are as follows: Defined and undefined data are declared as follows: The sum of program and data memory cannot exceed the 2K byte limit.
Reset will end STOP. The symbol name will be assigned a constant value as if via CON which is the current data pointer. NAP x Enter low-power mode for a short period. STOP Execution is frozen, but low-power mode is not entered.
Initially, the DATA location is set to 0. Non-unique variables are in-whole or in-part derived from unique variables and get assigned within the unique-variable memory.
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 Miicroprocessadores compiler will always tell you when you have a conflict. The pin may be filtered by an RC circuit to achieve a clean sine-waves.
This allocation is automatic. PWM pin,duty,cycles Pin will be temporarily made an output while it is modulated. For defining unique variables: The pin may be filtered by an RC circuit to achieve a clean sine-wave s.
Defined data is fully declared and known at compile time. Here are all the variable modifiers: It is advanced by 1 for each byte declared. Keep in mind that you may make alias names for the pin variables: Enviado por caetano flag Denunciar. The result will be written into variable.
Enviado por caetano flag Denunciar. Freq2 is optional and specifies a second frequency. Your data, on the other hand, builds from the start of memory towards the end. RCTIME pin,state,variable Pin will be placed in input mode and time will be measure in 2us units while pin is in ‘state’. 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.
The resistor-cap junction will reflect the duty V during and after PWM. The x values for NAP are as follows: Use Alt-M to see this. Duty is an 8-bit value which specifies the duty-cycle. A digital-analog converter can be made by connecting the pin to a resistor which goes to a cap which goes to VSS.

Freq1 specifies the first frequency in 1Hz units Hz. The default on and off times are ms and 50ms. Alt-M lets mciroprocessadores see the result of this process.
