Update to BS2_Functions

Martin Hebel

Here is an update to BS2 Functions.· Some notable highlights include:
· - Continual PWM using the counters·using PWM_Set and PWM_SetB (and regular PWM with duration)
· - EEPROM Write/Read·functions for·top of code space, normal code space (variable saves), and upper 32K (Thanks Paul Voss!)
· -·FREQOUT_SetB for second·Frequency continually
··- A bug fix on SERIN inverted data

For those who·use BS2_Functions, please let me know if I induced any bugs!· As always, don't forget to·BS2.Start(31,30) it!

I'll give it a few days to settle before updating the Object Library's code.

Thanks,·hope it helps some people!

        Added functions for:
                FREQOUT_SetB(Pin, Freq)
                      To sound a second tone on the defined pin continuously
          EEPROM Access:
                Read(Addr,size) where size is number of bytes (1 for byte, 2 for word ,4 for long) 
                       Read EEPROM in code space, from top (32767) to bottom (0)
                       myVar := Read(0,4) ' long, 4 bytes
                       
                Read_HighMem(Addr,size) where size is number of bytes (1 for byte, 2 for word ,4 for long)
                       Read upper 32K of 64K EEPROM
                       myVar := Read_HighMem(3,4) ' read a long, 4 bytes
                       
                Read_CodeMem(Addr,size) where size is number of bytes (1 for byte, 2 for word ,4 for long)
                       Read from direct code memory
                       No coding required, variable or stack will have last value saved
 
                Write(Addr,Value, size) where size is number of bytes (1 for byte, 2 for word ,4 for long) 
                       Write to EEPROM in code space, from top (32767) to bottom (0)
                       where 0 = top of memory
                       Write(0, myData,4)   ' write long myData to top of memory
                       See precautions in method comments
                       
                Write_HighMem(Addr,Value, size) where size is number of bytes (1 for byte, 2 for word ,4 for long)
                       Write to upper 32K of 64K EEPROM
                       Write_HighMem(0,myVal,2) ' write byte variable myVal to upper 32K lowest address
                       See precautions in method comments
                       
                Write_Code(MemAddr,Value, size) where size is number of bytes (1 for byte, 2 for word ,4 for long)
                       Write to direct code memory
                       Useful in having a variable survive a reset
                       Write_I2C(@myData,myData,4)
                       See precautions in method comments
           PWM:
                PWM_Set(Pin, Duty, Resolution)
                       Sets continuous PWM on pin specified, for value and bit resolution specified
                       PWM_Set(Pin, Duty, resolution)
                       PWM_Set(2,500,10)  ' 10 bit resolution, 0 to 1023 Duty
                       
                PWM_SetB(Pin, Duty, Resolution)  
                       Sets wnd continuous PWM on pin specified, for value and bit resolution specified
                       PWM_SetB(Pin, Duty, resolution)
                       PWM_SetB(2,100,8)  ' 8 bit resolution, 0 to 255 Duty
 
                PWM and PWM_100 functions have been adapted to use PWM_SetB.
          DEBUG:
                DEBUG_CR
                        Sends a Carraige return for DEBUG (CR - ASCII 13) 
        Note: FREQOUT and FREQOUT_Set use CounterA.  FREQOUT_SetB uses Counter B
              PWM_Set uses counter A.                PWM, PWM_100 and PWM_SetB use Counter B
              Counters can only be used for one purpose at a time (when ran from same Cog).               
        
        Bug Fix:
             Actually inverted the data on SERIN when #INV mode is declared!! Thanks Glenn Tarbox!
             ... Hope I did it correctly, not tested!

Martin, I'm looking forward to the new release.· I use BS2.Functions quite a bit and it really simplifies things.· Did you correct the logical order in the shiftout/shiftin methods?

Yesterday is history, tomorrow is a mystery, and today is a gift.

That is why they call it the present.

Don't have VGA?

Thanks Sid,
No, I didn't change the order of the parameters, it would have broken compatibility with prior code using it. It's always best to look at the documentation when calling any method.
