Is it possible for the TIMER function to return fractions of a mS as we have on the CMM2.
Even a resolution of 10uS would be very helpful.

ArmmiteF4 firmware V5.07.00b13

ArmmiteV5.07.00b13.zip

Now also supports the DHT11

New syntax:

HUMID pin, temp!, humidity! [,version]

Valid codes for version are:
1 = DHT11
0 or omitted = DHT22

TIMER now returns the time in milliseconds as a float accurate to the microsecond

Thank you.
That will open up possibilities and make life more interesting.

Thanks Peter and Jim
Perfect results from V5.07.00b14

> humid 15,temp,humidity,1
> ? temp,humidity
13 72
> timer=0 : pause 1.234 : ? timer
1.257

It would appear it takes just 23 microseconds for the print command

Any possibility of CRC16/32 commands? Would be handy for various communications purposes. While this could be done in Basic, internal (compiled code) processing would be much faster, not to mention the STM32F407 has the CRC calculation unit on-chip so this should be even faster than internal compiled code?

hehe - perhaps we just need a EVERYTHING command that does all the nice little bits that we'd like. :)

Not quite.
The TIMER function is run before the PRINT so PRINT knows what to print.

My notes say that on February 27, I was able to initialize an SPI ILI9341 on the F4 with OPTION LCDPANEL ILI9341, L, 87, 97, 33.

Today, with ARMmite MMBasic Version 5.07.00b7, I get this:

> OPTION LCDPANEL ILI9341, L, 87, 97, 33
Error : Pin | is reserved on startup
>

The equivalent OPTION LCDPANEL ILI9341, RLANDSCAPE, PD6, PE0, PC4, gives the same error message.

What has changed? (And can the error message be updated to say which pin it is referring to?)

The earlier versions before beta9 did not release all the pins on
OPTION LCDPANEL DISABLE for the SPI displays.
OPTION RESET should fix it for Beta7

Also, if you use an invalid pin you will get a similar error message with the same "|" pin identifier.
For display configurable pins (e.g. RESET, DC) you will get an error if attempting to use an invalid pin:
>OPTION LCDPANEL ILI9341, LANDSCAPE, PE15, PE13
Error : Pin | is invalid
(PE13/15 are invalid pins)

Would be more user friendly if the "bad" pin is expressly identified.

I am stuck on the correct line to open com2 at 9600 with no parity and 1 stop bit with inverted polarity. I have followed the manual but no go. Using version 5.07
Help please

STM32 processors do not support inverted serial - seems to be a particular feature of PICs

Thanks Peter
I was beginning to suspect that was the case. I will go the hardware route. I am attempting something along the lines of

ArmmiteF4 firmware V5.07.00b14

When using PWM channel 3 the PWM 3,STOP command does not stop the PWM bit stream. STOP works fine on channel 1 or 2, but once PWM is started on channel 3 there is no stopping it.

The SERVO command using channel 3 also won't stop, channels 1 & 2 are ok.

ArmmiteF4 firmware V5.07.00b15

ArmmiteF407V5.07.00b15.zip

Fixes problem in PWM STOP for channel 3
Fixes bug in I2C2 OPEN

New math command

MATH M_INVERSE array!(), inversearray!()

This returns the inverse of array!() in inversearray!(). The array must be square and you will get an error if the array cannot be inverted (determinant=0)

New math function

MATH(M_DETERMINANT array!())

returns the determinant of the array. The array must be square

Enhancement of the RESTORE comand
The restore command can now take a variable as the parameter. A numerical variable should be used for a line number and a string variable for a label

Enhancement of the READ command
The read command can now take arrays as one or more of the parameters. As usual arrays are specified with an empty set of brackets.

e.g READ a,b c(), s$(), t$
This will read numbers into a and b, it will then fill the array c() with numbers (NB: if C is multidimensional then the leftmost dimension will be the fastest moving). It will then fill the array s$() with strings and then finally load the string t$. In all cases the firmwware uses the size of an array to determine how many elements are to be read.

Hi Peter,

Confirming that PWM STOP for channel 3 is working now.

Many Thanks,
Phil.

Is there a reason why the OPTION LIST command on the ARMmite F4 doesn't report the GUI CALIBRATE parameters for the LCD like the MM2 & MM+ do? Can this info be added to the OPTION LIST output if a touch enabled LCD is connected?
