Re: Playing with "Blue Pill"

... I checked out the page, and it infers that if you use the Serial upload method (like I am doing), the USB Serial enumeration is not present. Is that correct? If so, is there a way when I am *not* using the stm32arduino bootloader -- but using the built-in Serial upload instead -- to use the nat...

Thanks, Ray.

BTW, my wife is from Marietta... maybe some day we can meet for a cuppa.

Oh, yes, I started drinking coffee when in the USAF and working those long mid-shifts in the comm-center in Misawa, Japan (1970/1)

Re: Playing with "Blue Pill"

Welcome Steven; But I was wondering about using the native USB port for basic Serial I/O (*not* for flashing - I understand the need for a different bootloader; I am satisfied with the separate serial I/O flash for now). Should the native USB serial interface work when using the Arduino IDE? If not,...

Re: Can upload with bootloader but no COM ports afterwards

There are "special" post-core installation requirements: see https://github.com/rogerclarkmelbourne/ ... stallation

If you are running Linux let me know if the UDEV rules script does not do the trick.

Re: HDC1080 and MS5611 sensors

... P.S. What does OP mean? OP == Original Poster ... generally the 1st person to post in a thread I found an old BP-180 in the parts bin and ran it with both software scanner and hardware scanner (from the examples under "Wire" and both sketches found the sensor without issues. However, the hardwa...

I have a project that have a very crazy BUG. :shock: If you wish to know what the "F" macro does, this is a good explanation: http://forum.arduino.cc/index.php?topic=91314.0 Serial.println(Serial(F("Teste"))); <= This doesn't WORK Should be: Serial.println(F("Teste")); # define io_led 11 ... if (bu...

Re: HDC1080 and MS5611 sensors

... if I scan with the Hardwire scanner I see only 2 devices - not the MS5611, but if I scan with the Softwire scanner I see 3 devices , which includes the MS5611. Well, that certainly seems odd (and not in a good way.) Maybe an I2C guru is out in the forum and has an answer. This may be one of tho...

Welcome to the forum Brad. Sounds like you are on the fast track using microprocessors. I play around with just about anything that I take a fancy to.. https://www.hackster.io/rayburne/projects If you have not read my post here: http://stm32duino.com/viewtopic.php?f=2&t=3111 You may find it useful. ...

I never manage to do that, but they say that you could burn receiver if you are to close to sender.

And you are really close :)
In a well designed board, the RF input should be protected, even if the send unit is adjacent ... as in my test picture.

Re: HDC1080 and MS5611 sensors

... Any ideas? I2C was originally done in software, soft I2C. However, the code has been revamped and now is hardware I2C, last Sept. https://github.com/danieleff/STM32GENERIC/blob/master/STM32/libraries/Wire/src/Wire.cpp#L7 Here is the announcement: http://www.stm32duino.com/viewtopic.php?t=2408 G...
