strange, most modules seem to come with 3v3 reg these days
ok now i follow, max31856 modules are 2.5x the chip price :o

favour please, see if the i2c scanner examples work?
if so,
which board and/or variant?
what arduino version,
date of arduino_stm32
which platform etc etc

i2c scanner worked just fine when I last ran it.

I've not cloned the stm32 repo for about 4 weeks though...

1.81 IDE

Board is a Maple Mini clone, it looks exactly like a Baite but doesn't have the logo on the silkscreen

Just ran it again:

Code: Select all

Scanning...
I2C device found at address 0x1E  !
I2C device found at address 0x53  !
done


That's with clone just now from stm32 github.

i'm using arduino 1.8.2 and ard_stm32 is clone --recursive of repo, 'master' as of yesterday

my magic is working again, remember 4000 series cmos, look at it askance across the room and it died.
i honestly believe i am much the same with usb bus, i2c bus & stm32
mind you i got Enrf24 returning correct status, actually one of the 103rc with built-in nrf24 socket, so not all bad.(on the wiki)

looks like a clean install is required. again and again.

totally off the cuff, one of the vendors for a stm32f407 boards is adding a panel 'click here to add suitable display' to order

display is extravagantly priced, but then again no hunting for suitable one. i think the board is not so bad

might be, its a home compile of github, i uniquely name the ./.arduino15 directory
to something including the version ./.arduino-182. i'm now running 1.8.1 compiled from their archive source code and ./.arduino-1.8.1r0 as config dir. and Due installed etc, etc

scanner-wire seems to have unknown error for all device addresses, scanner-hwire has a device at all addresses.

saying that if i use todbot(?? original author) scanner, that works fine on avr
i'll try again with a virgin blue pill when i find the soldering iron. first i'll try with uno and or a nano

This is why I try and stick with the unwashed masses unless I _really_ have to diverge from stability

Isn't a recumbent sort of like a C5 without a motor? ie way too low :D

Probably well ahead of its time. With rare earth magnet motors and LiPo storage I'm sure it would be possible to create a decent version.

In fact Clive Sinclairs nephew has designed a new version.
