Re: MM board not detected on one machine.

kindly provide the outputs of lsusb particularly abstract the entries relevant to 1eaf and dfu-util -l sketch uploads only work when the device has usb id: 1eaf:0003 (maple mini is in bootloader DFU mode) and that dfu-util -l returns appropriate response rather than an error. and if it is a maple mi...

Re: Anyone tried to make a 3D Printer controller?

this repository seem a little 'hot' https://github.com/St3dPrinter/Marlin4ST http://www.st.com/en/evaluation-tools/steval-3dp001v1.html ^^ this is ST's 'own' 3d printer board somewhat pricy at $116 looking at the schematics they are using L6474 stepper drivers http://www.st.com/content/ccc/resource/...

Re: Install STM32duino on Raspbian?

it would seem to me that there isn't any arm-none-gcc/g++ compiler tool chain on arm platform itself isn't it?

Re: Recommended TFT LCD displays for stmduino compatible boards?

agree with chris, if you would like to go with st's products there are some stm discovery boards with on board lcds http://www.st.com/en/evaluation-tools/32f746gdiscovery.html http://www.st.com/en/evaluation-tools/32f429idiscovery.html however, i'm not too sure if libmaple's stm32duino would run on ...

Re: Anyone tried to make a 3D Printer controller?

Re: does stm32f1 gets too hot in a project box? and temperature sensor

ok thanks ! that sounds encouraging, would shop around for a box and try to fit them in :D stm32f103 maple mini / blue pill + ili9341 maybe + some buttons (mine didn't have the touch screen, but get the touch screen one if you are getting an lcd) as it seemed is a pretty good bundle of things to put...

Re: does stm32f1 gets too hot in a project box? and temperature sensor

thanks pito, fred, i'm thinking of fitting a maple mini + ili9341 display in a plastic 'project box' https://www.ebay.com/sch/i.html?_from=R40&_nkw=project+box&_sacat=0 at the moment trying to figure out how to make the holes (e.g. for the lcd) and how to fasten the components, maple mini do not hav...

does stm32f1 gets too hot in a project box? and temperature sensor

has anyone placed an stm32f1 (blue pill / maple mini) in an enclosed project box? does it 'get too hot' in an enclosed project box? apparently there is an internal temperature sensor on the stm32 (f103) but is apparently 'seldom used' http://www.programering.com/a/MDN3IDNwATE.html http://www.onarm.c...
