Peter, I cannot "resist" asking; what melted and carbonised your prototyping board so spectacularly? I bet the house needed an air-freshener after that one...

Just a small question if I may, does the PAUSE timer use the same clock as the RTC?
In a short program I have to pause 1020 mS to get the next RTC second. (If that makes sense)

No RTC is Xtal, Pause uses internal RC

It was me. I power cycled the mite and all is good now.
Sorry to annoy you so early in the morning Peter.

Hi!

Is there a way to wake up the controller at a certain date/time (RTC)?

(After playing around with the board for a while, the RTC suddenly went wrong by a few minutes - but unfortunately can't reproduce the error...)

I also had a problem with the editor: I wanted to append a few "0" to a number whereupon the editor suddenly moved or deleted any other places in the code - leaving and calling the editor did not change anything. The code was displayed corrupted. Only a restart of the �C brought remedy - but the code was still intact...

No, but perhaps I'll include it

Quote I also had a problem with the editor:

What terminal are you using?

Can't remember if I've posted a version with the new console code. Try this version

Hi Peter,
I think there is some sort of thing/artifact in the OPTION LIST in the latest version.
See below the first OPTION LIST entered after a flash.
Putting a valid entry in seems to make it go away.
Remove the valid entry and it comes back.

> option list
OPTION LCDPANEL , GDEH029A1

> option lcdpanel USER,128,64
> option list
OPTION LCDPANEL USER 128, 64

> option lcdpanel disable
> option list
OPTION LCDPANEL , GDEH029A1

> ? epoch(now)

In trying to flash the Armmite L4 with the ST-Link utility, I get the message, "The elf loader file is not accessible." I can see the ArmmiteL4.elf file, but I haven't been able to figure out what to do with it.

Clicking "External Loader" and "Add External Loader" doesn't appear to give me any way provide the location of the file.

What do I need to do to proceed? (Win7)

You should be using the HEX file, not the ELF for ST-Link utility.

This is the procedure I use for the H7 and the L4:

Quote
I just tried setting up my laptop with ST-LINK and a new, straight from the box NUCLEO board.
There was no previous ST software or drivers on the laptop so virgin territory.

It was easy.

Download STM32 ST-LINK Utility (en.stsw-link004.zip)
Extract the setup file and run it.
It will install the required drivers during the setup.
Start ST-link
Plug in the Nucleo board.
It works out-of-the-box without touching any jumpers.
Ignore the Windows �What will I do now?� message.
Click on �Target/Connect�
It is advisable to do a full erase
Target/Erase Chip
Go to �File/Open file� and open the armite.hex firmware file.

Go to �Target/Program and Verify�
When that's done.
�Target/disconnect�
Close the program and open up your preferred terminal program.

You might get some initial garbage in the serial stream.
It�s really that simple.

IF you have more than one device connected, you can chose which one in the settings menu. It would be a good idea to stick with one at a time. The serial numbers aren't written on the devices anywhere.

External power will be required once you start adding displays etc.

Thanks for that. Similar to what I was doing.

However, when I do Target/Erase chip, I get "The elf loader file is not accessible".

If I omit the Target/Erase step and go to File/Open (and open ArmmiteL4.hex) and Target/Program and Verify, I get the same message.

Hi Peter,
Any chance of adding 0.91" SSD3306 128*32

I have written it as a basic driver based on your previous example.

The changes are.
OPTION LCDPANEL USER,128,32 'MM.VRES reads as 32

During initialization two changes:
OLED.SCmd(&HA8)'MULTIPLEX
'OLED.SCmd(&H3F)' 3F required for 128x64 display
OLED.SCmd(&H1F)' 1F required for 128x32 display

OLED.SCmd(&HDA)'COMPINS
'OLED.SCmd(&H12)'12 for 128*64
OLED.SCmd(&H02)'02 for 128*32

The buffer required is only half the size so
for i% = 0 to 3 'was 0 to 7
s$(i%)=string$(128,chr$(0))
next i%

Possible tweak to your current syntax so it could be in ARMmiteL4:
Option LCDpanel SSD1306I2C, orientation [,type] 'set type=0(default) for 0.96";1 for 0.91"; 2 for 1.3" displays

Regards
Gerry

There is actually a much easier way to program the L4 and the H7 than using ST-LINK as they are both MBED enabled. I hadn't tried it before because it doesn't make sense when developing but for distribution it is excellent.

The attached ZIP contains a ".bin" file as well as the .elf and .hex

If you open the file manager on your PC with the Nucleo plugged in you will see a disk named "NODE_L432KC" or something similar. Just copy the .bin file to that disk and magically the STM32 is updated

This also fixes the OPTION LIST error

Hi Peter,

thank you so much for your "cpu sleep epoch"!

It works very fine! Have you measured the power consumption during that time?

(I am using Tera Term as terminal program.)

Do you think there is a way to write a Basic driver for an Adafruit LS013B4DN04 display?

...then I'd be a lot closer to my Micromite wristwatch!

Updating with the ".bin" didn't work for me - I had to flash the controller again...

Hi Frank,

Just out of interest, it says that the display is no longer produced; however there is a replacement which is slightly bigger - both physically, and in pixel resolution.

Highlighting this in case any driver Peter creates immediately becomes redundant due to lack of product availability.

The link for newer display is here
