Armmite H7 5.08.00 Beta 0 - Details
This firmware will cause a full reset of MMBasic as it has some additional commands.
The Program and Library areas will be cleared and Options set to default.
Please report any issues with any of your existing programs.
Conversion of existing programs
BASE$([2,8,16],n) commands will automatically be convert to appropriate BIN$,OCT$,HEX$ when saved.
CLEAR VARS will automatically convert to ERASE when saved.
BITBANG becomes DEVICE, automatically converted when saved.
Any MM.INFO(various..) are kept as is and work as usual. Convert to MM.xxx as you please.
The changes
The allocation of heap memory is enhanced so memory required to execute commands, SUBs and Functions is allocated from the bottom up and does not have to search past memory previously allocated to variables from top down. This can offer significant performance improvement when many variables are allocated.
Function Inkey$ changed so it automatically resolves Function and special keys
sequences to a single char as per picomites and CMM2.
INKEY$() function now internally in the firmware calls the MMInkey(); function in lieu of the getConsole(); function. This now aligns across the Picomites, CMM2, ARMmiteF4 and ARMmiteH7. The Micomites call the getConsole(); internally.
The call to MMInkey(); will resolve any supported escape sequences sent by a VT100 terminal to a single ascii character as detailed in the manual Appendix J.
Previously to detect Function keys etc which send an escape sequence you would have to make your own arrangements to recognise the ESC character and then decode the following escape sequence. Any current program doing this will need to be adjusted to recognise the appropriate single ascii character for the key.
If you really want to access the raw characters use the INPUT$() function which still calls getConsole(); when a filenmr of ) is used. e.g. char$=INPUT$(100,#0)
Firmware now uses FLASH BANK0 Sector 1. Previously this was skipped for OPTIONs but OPTIONs are actually in FLASH BANK1
The address of the CallTable is now 0x080004A0 in lieu of 0x080402A0.
The ARMH7CFunctions.h file used for CSUBs is updated to match this.
CAN [OPEN|CLOSE|START|STOP|FILTER|SEND|READ] commands added
SYNC [period][,units] command added
MATH PID command and function added.
BYVAL and BYREF qualifiers added to SUB and FUNCTION definitions.
PWM will set output pin to OC(Open Collector/Drain) if frequency given as -ve number.
PWM fixed issue where a frequency change was not recorded, so returning to the original frequency did not result in an update.
Support for LCD Display ST7796S 480*320 SPI
OPTION LCDPANEL accepts [,INVERT] to invert colours on ILI9341 and ILI9488
MEMORY command Fixed issue where it erased saved variables.
Functions MM.HRES, MM.VRES, MM.VER, M.I2C, MM.FONTHEIGHT, MM.FONTWIDTH, MM.HPOS, MM.VPOS, MM.ONEWIRE, MM.Errno, MM.ErrMsg$, MM.WATCHDOG, MM.DEVICE$,MM.WIDTH,MM.HEIGHT
are now all implemented as written and none of them are converted to MM.INFO calls by the pre-processor
MM.DISPLAY added, indicates whether a OPTION LCDPANEL CONSOLE is used.
MM.CMDLINE$ is now a function and does not need to create a variable.
All pins can now optionally be set using the port syntax (PA0-PG15)
MM.INFO(PINNO port) added. returns the pin number.
MM.INFO(NBRPINS) added, returns number of pins (100/144)
MM.INFO(OPTION VCC) added returns current value for VCC
MM.INFO$(ID) Returns the unique hex 12 byte ID of the Armmite chip as a string.
MM.INFO(ID48) Returns a 48bit hash of the ID as an integer. Not guaranteed unique world wide but most likely unique for a hobbyist. Suitable as a serial no. for the device and at 6 bytes fits inside a CAN message.
MM.INFO(HEAP) added
MM.INFO(BOOT) will return the reason for the last MMBasic Restart.
“Power On”, ”Reset Switch”, “MMBasic Reset”, ”CPU RESTART”, “Watchdog”, “EXECUTE Timout” or “HEAP Restart”.
These could be written to a log file in MM.STARTUP to see the history of an unattended device.
OPTION CONSOLE [BOTH|SCREEN|SERIAL|NONE] added
OPTION NOCHECK [ON|OFF] added.
MATH C_ADD etc commands that act on cells added as per picomites.
MATH SHIFT added as per picomites
MATH WINDOW added as per picomites
MEMORY PACK/UNPACK added.
MEMORY PRINT/INPUT added
MATH M_MULT Fix for not giving correct results.
MATH M_MULT Improved as per Pico RC5
MATH M_PRINT Improved as per Pico RC5
MATH V_PRINT array() [,hex] 'outputs the contents in hex
MATH command accepts either C_MUL or C_MULT. (as per Picomite)
LINE command enhanced. LW given as -LW will set LW in all directions
LINE AA command added as per picomites
LINE GRAPH command added as per picomites
LINE PLOT command added as per picomites
MATH CROSSING() added
LIBRARY RESTORE will restore any existing library after OPTION RESET provided no explicit LIBRARY DELETE has been given.
LIBRARY SAVE future proofed for 16bit tokens.
I2C READ allows >255 chars if INT or Float array used.(as per Picomite)
CommandLine Buffer automatic OVR mode on right arrow removed.
USBKeyBoard:
Fixed issue where USBKeyBoard did not connect reliably.
Console message now given when USB Keyboard is either Connected or Disconnected.
Added delay in USBKeyboard handling of CAPS/NUM/SCROLL Lock to improve operation of LEDs on some keyboards. see https://www.thebackshed.com/forum/ViewTopic.php?TID=17037
USBKeyboard mappings corrected so that SHIFT+(F1-F12) resolve to correct codes
i.e. 0xB1- 0xBC in lieu of 0xD1-0xDC. See Manual Appendix J
INSTR fixed when an expression is used as the index to an array as the first parameter (as per picomite RC9)
Comments are no longer tokenised as per Picomites.
SORT command extra sort option
LINSTR Fixes bug in changing the regular expression if a variable.
SHIFT F3-F8 Added as per picomite 6.00.02B0
//NB: SHIFT F1, F2, F9, F10, F11, and F12 don't appear to generate anything
ADC START now accepts additional parameters as per the Picomites that allow mapping of the the output data to a desired range.
ADC TRIGGER now allows a timeout value to be set. 'timeout' is the number of ADC samples to take before abandoning the wait for the trigger condition. Setting a value equal to the frequency of the sampling would give a timeout of 1 second.
ADC TRIGGER,channel,level[,timeout]
LONGSTRING PRINT allows ; to suppress CRLF
PIN("TEMP") adjusted to calculate using correct value of 130 degrees for REV V chips.
BITBANG becomes DEVICE as per picomite latest release.(automatically converted)
DEVICE BITSTREAM
DEVICE LCD
DEVICE HUMID
DEVICE WS2812
HEX$,BIN$ and OCT$ now restored. BASE$(2, etc accepted but automatically converted)
ERASE command restored. CLEAR VARS automatically converted
Automatic length adjustment for string constants.
Where a constant string is less that 16 characters no heap will be used. The data is stored within the pre-allocated table for the variable definitions.
String variables defined with a LENGTH of less than 16 (was previously < 8) are also stored within the variable definition and require no heap allocation.
@( function added. i.e. PRINT @(x,y[,m]) when outputting to the VT100 console or LCD
TEMPR(Pinno [,timeout]) 'new optional parameter timeout to override the default (200mSec) to allow for slow devices.
TEMPR START pinno [,resolution(0-3)] [,timeout] 'new optional parameter timeout to override the default (100, 200, 400, or 800mSec) to allow for slow devices.
