I've taken to using the "old" method b'00000000' instead of 0b00000000 to get round this bug.

Anobium - 2020-01-30

The next release has a major change with respect to the setting up of the oscillator when NOT using the internal oscillator.

Some background

We need enable the user to use other internal oscillators like LFINT, and, to expose the oscillator type (with frequency) and class to the user. So, the users know what is going on.

So we needed to
1. A method to enable setting of alternative internal oscillators.
1. NOT set the Oscillator when using a non-internal Oscillator

Changes

A constant so we can change the setup (within initsys() ) to handle non-internal and other clock sources specifically LFINT (which is an internal Oscillator).

A constant that specifies the oscillator type. We need to be able to determine what is INT (as is today), what is external – so, we can set the internal clock sources, and, if external let the use the user do it as we would be guessing.

A consistent method of exposing the selected oscillator and frequency for reporting to the user, with the frequency.

A method of automatically selecting internal SOSC when the selected 0.03268 is the operating frequency. Therefore the compiler needs to set the config appropriately.

Using the latest compiler.

What does the user now see?

In the IDE the following are examples. Note the clock source, the frequency and more key information.

Compiler Version (YYYY-MM-DD): 0.98.<<>> 2020-01-28 (Windows 32 bit) Program Memory: 81/65536 words (0.12%) RAM: 0/2048 bytes (0.0%) OSC: HFINTOSC_1MHZ, 64 (Internal oscillator) Chip: 18LF67K40 Compiler Version (YYYY-MM-DD): 0.98.<<>> 2020-01-28 (Windows 32 bit) Program Memory: 59/65536 words (0.09%) RAM: 0/2048 bytes (0.0%) OSC: Default Oscillator Source, 0.031 (External oscillator, clock source must be connected to PIC oscillator pins) Chip: 18LF67K40 Compiler Version (YYYY-MM-DD): 0.98.<<>> 2020-01-28 (Windows 32 bit) Program Memory: 59/65536 words (0.09%) RAM: 0/2048 bytes (0.0%) OSC: LFINT, 0.031 (Internal oscillator) Chip: 18LF67K40

New constants ChipUsingIntOsc and ChipOsc

Two new chip specific constants now exist.

ChipUsingIntOsc ChipOsc

ChipUsingIntOsc will exist if the internal oscillator is selected by the compiler.
ChipOsc constant gives the actual oscillator chosen, which matches what is displayed during compilation.
ChipOsc is the user specified or compiler select oscillator, Use ChipOsc the same as the constant ChipName.
ChipOsc matches whatever is shown for the Osc in verbose mode, so for example when the 16F88 is configured for internal, it uses INTRC_IO in the assembly, and this tests true:

#ifdef ChipOsc INTRC_IO …. ….. #endif

Usage

Users we be able to use #if ChipUsingIntOsc in the source code to handle internal oscillator in initsys, and the ChipOSC constant as a fallback.

Note: If there is some new type of internal oscillator that the ConfigValueMatch() routine in gcbasic.bas does not correctly recognise as an internal oscillator we will have to update the compiler

Example compilation

Automatically setting chip speed to 48 Mhz Calculating CONFIG ... Chip Settings: Chip Model: 18F25K50 Chip Family: PIC (16) Clock MHz: 48 RAM: 2048 Oscillator: INTOSCIO Running compiler scripts ...

Example user code

#chip 16F88, 20 PulseOut PORTB.0, 500 ms #ifdef ChipUsingIntOsc PulseOut PORTB.1, 1 s #endif

Changes to core setup

The following changes have been made uses these new constants.

When a user specifies a frequency of 0.031, at the moment, ONLY this frequency, and the chip has an internal LFINTOSC the compiler will automatically setup the clock.

When a user specifies a frequency that is NOT an internal chip frequency the compiler will NO LONGER setup the oscillator registers. The user will no longer be confused by the compiler trying to setup the internal oscillator.

When a user specifies a clock source the constants will match the selected clock source

Prerequisites

To make this all work.... you will need a compiler version 0.98.07 or greater AND new dat dated 30 Jan 2020 or later.

Question

Should we add a new user constant to stop ANY setup of the oscillator registers? Leaving the oscillator register setup totally to the user.

Anobium - 2020-01-30

Chip listed in the attachment will have the LFINTOSC clock source set correctly when the frequency is 31k for LFINT or LFINTOSC

The 96 chips are essentially the following chip classes

PIC(L)16F15xxx PIC16(L)F18xxx PIC16(L)F19xxx PIC18(L)FxxK40 PIC18(L)FxxK42 PIC18(L)FxxQ10 PIC18(L)FxxK83

Enjoy when you get your hands on the release.

Thanks to all involved in supporting this functional change - Hugh, Jim, Pierre and me!

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
- Anobium - 2020-01-30
  
  Edited... I made a bit of error.. not SOSC but LFINTOSC. Correct below.
  
  During testing I found specifying the LFINTOSC clock frequency as non-intutive... getting 0.031 correct is hard. I had even incorrectly typed in these posts.
  
  So, we may (not this is passive) add another feature where you can specify 31k as the frequency to aid usage. So, the following could be implemented.
  
  #chip 16f18326, 31k

Chris Roper - 2020-01-30

Should we add a new user constant to stop ANY setup of the oscillator registers? Leaving the oscillator register setup totally to the user.

Not a bad Idea, Something like..

#Option UserOSC

As it is not feasible for the compiler to be able to preempt or handle all of the possible clock options having an override will let the user manually configure the Internal or External OSC to allow fringe cases, accurate timing or synchronised clock situations.

GCBASIC’s ability to use Direct register access will allow the user to setup the Internal and External options to suit their own application or hardware specification.

Cheers

Added new frequency option for crystal clock sources.

#chip 16f18326, 32.768k For crystal clock sources.

So, I have have added two options, the one above and this one.

#chip 16f18326, 31k For LFINTOSC clock sources.

  Frank has updated the IDE to support the two new frequency as constants. Which means these specific chip frequences will be shown in black and not as numerical values.
  
  This changes help you get these constants correct.
  #chip 16f18326, 32.768k
  #chip 16f18326, 31k

WANTED

Looking for people to review the next release.

We are close to the release. And, I need folks to test, compile code and try to use the new release.

So, if you are a Windows user - please ping me. You need to be willing to compile existing projects and test again what you know works. We need to be assured that we have no broken anything. We have 1000s of static and closed loop feedback tests (we know what the output should be with the static tests) but there is nothing like users testing the code.

In the past I emailed many of you. Not this time.

Please offer your help - your level of skill is not critical - we need you compile your code and to tell us that all is good.

Cheers

Changes add since #704.

704      Fix      HWI2C(2)  Functional change: Improved to handle out of band frequency selection based upon chip frequency, corrected SSPADD mask[977, 1012]
705      New      Compiler  Added setting of ChipOsc and ChipUsingIntOsc constants based on oscillator in use (PIC only) [988]
706      Fix      Compiler  Fixed bug in parsing of binary literals starting with 0b when at the very start of a line [988]
707      New      Language  Updated message.dat [989]
708      New      SYSTEM    Updated to change the setup (within initsys() ) to handle non-internal and other clock sources specifically LFINT (which is an internal Oscillator).
                            Automatically sets internal LFINT when the selected 0.031 is the operating frequency. Therefore the compiler needs to set the config appropriately [990,993,1004, 1003, 1002, 1001,1000,999, 998, 997, 995, 1077 ]
709      New      Compiler  Updated to support LFINTOSC via "32.768K" and "31K" and 125,250k and 500k replacing for frequency [991, 992, 1007, 996, 1010]
                            Compiler isses a warning when an unknown xxK is specified.
710      New      PPSTool   Updated to cater for K42 warning messages.[30,31]
                            Also, updated to include a method to automatically download and update the XML files from Microchip - but you need at least .net framework 4.5 for it to work.
                            If 4.0 is as high as you can go (i.e. windows XP) it still works as before so don't worry XP users.
711      New      DAT       Added LFINT value called LFINTOSCClockSourceRegisterValue (sourced from CSV file) for internal OSC and correct Help entries[994,1005]
                            Resolved 16f15313 family chips with incongruous data entries.

713      Fix      USE.INI   Updated USE.INI Corrected typo in AVR_Chips_Using_PK2. Replaced  "Filename"  with %Filename%
                            Also, changed PK+ to PICKIT+ in description field.
714      New      PPSTool   Updated tp handle XML files available (v1.79.0). [31]
715      New      Compiler  Implementation reservedwords list for GOTO. Removed END. [1006,1018]
716      Fix      Compiler  Resolved bug with variables that start with Return like ReturnValue [1008]
717      Fix      SW I2C    Added LEFT to rotate I2CByte left on line 421 to explicitly state rotation[1011].
718      New      Compiler  Added "XINST" to the default ASM. Using an alternative like MPLAB IDE explicitly 'set' the XINST as it was not specified. Adding XINST=OFF resolves for the future.[1014]
719      Fix      GLCD      ILI9341 and ILI9340. Corrected the INIT to handle DI port [1015]
720      Fix      DAT       Large memory Q10 and K42 now have a valid DAT file.[1016]
                            All Q10 have debug bit removed

722      Fix      Compiler  Added CPD=OFF as a default for 18F [1019]
723      Fix      Compiler  Fixed to for TABLE creation error where the table data was corrupted when hex data was defined like 0x4B'comment or -0x3B'comment. The trailing B was being picked up as Binary data.[1020,1025]
724      New      Compiler  Support for // and /* BLOCK COMMENTS */ [1021,1022]
725      New      IDE       Support for // and /* BLOCK COMMENTS */ in IDE
