Re: Firmata for a Maple Mini

Aram, It has been over 12 months since Firmata has been discussed and to my knowledge the port was not completed; see here. http://www.stm32duino.com/viewtopic.php?f=15&t=463&start=30#p20894 Now that Frédéric has Firmata working for Neucleo, the clone boards should be straightforward - hopefully. ht...

Re: stm32f103c8 or esp32 for a datalogger

Readers sometimes forget that WiFi can be disabled and the uC current demands drop to 40mA @80MHz. https://www.hackster.io/rayburne/esp8266-turn-off-wifi-reduce-current-big-time-1df8ae Also, the unused flash can easily be configured as SPIFFS which is very easy to utilize in Arduino-ish programs: ht...

Re: [SOLVED] Volatile Qualifier

I am on Android at the moment and away from my home lab, do we know what the Neucleo core code has done? That is, will it behave similar? If so, I believe Roger and fpiSTM should probably discuss privately and make a collective recommendation.

Re: [Fixed]Analog pins definition

aramperez, As you are posting in the STM core section of the forum, I suspect your question is related to Firmata on Nucleo supported boards. Therefore this WiKi link is revalent: https://github.com/stm32duino/wiki/wiki/Firmata-example ADDITIONALLY, Please do not post into old threads that have been...

Re: Dear all

nairolf, Welcome. Sounds like you have self-struggled with the Blue Pill and are now ready for some project design. As a self-starter, you will find an overwhelming volume of information; for myself, much of my time is weeding through incorrect or vague online posts. Sounds like you are getting alon...

Re: Volatile Qualifier

<...> EDIT There are 548 hits in 47 files for "__io" of Arduino_STM32 core, STM32F1 directory. The cleanest solution would be to replace all those occurrences by "__IO" (make it uppercase) like in Teensy core, or by "volatile". Steve, I really hate myself (as I fight core changes usually) but in th...

Re: Readonly Serial Multiple Ports

<...> For 4 RS-232 serial, I would need like 8 Rx Serial/UART pins ... or should I use something different as I just need to READ ONLY, and I do not need to Tx anything back out .. Thanks The STM32F1xx has 3 hardware serial ports: http://docs.leaflabs.com/static.leaflabs.com/pub/leaflabs/maple-docs...
