Re: GOing mad trying to sort out sleep mode on STM32F103 Bluepill board

Wouldn't it be enough to re-execute a Serial.begin() at wakeup?! Perhaps. https://support.microsoft.com/en-us/help/817900/usb-port-may-stop-working-after-you-remove-or-insert-a-usb-device In Linux Mint 17.3/64, I have witnessed an upload to Maple, reset, and a different port being enumerated. I the...

Now it works under Android and in the Ubuntu VM. The problem was in a descriptor I grabbed from the libarra111 fork.
This is indeed interesting.

I played much a long time ago with the AVR-specific V-USB implementation. I also played with the ATmega32U4 "micro."

Re: Programmer's Manual?

Another option: Google search: STM32 site:github.com or Arduino STM32 site:github.com Many of the github directories have examples. Arduino examples STM32 site:github.com Even sites such as Adafruit sometimes shows results: Arduino examples STM32 site:adafruit.com or STM32duino site:sparkfun.com ......

Re: usb host contr stm32

Thanks ag123. I thought of using SD card but my PC don't have MMC reader . I want to connect it to one of Machine which send data through UART. Pendrive would be easy to connect to PC or to Mobile to check data. This surely seems to be an unusual response... is there more going on here that would p...

Re: Interesting pull request to add build options

Oh my, my, my ... I really have mixed emotions about this implementation; I n M y E xperience, work-arounds are rarely completely thought-out. Which is to say that they become fragile since the implementation is often implemented without a full team vote. In any event, the need for programmer overri...

Re: GOing mad trying to sort out sleep mode on STM32F103 Bluepill board

FYI At the moment Serial.end () does not power down the USB Serial . This is a known "feature" and there is a PR pending to fix this. ... of course, such a "fix" will kill serial enumeration over USB ... might as well unplug the USB cable. the fun part of this is that re-enumeration may not take on...

Re: Multiple I2C libaries

Hi, I am having troubles with multiple I2C libraries in one sketch on stm32f103 Separately they work: Adafruit SSD1306 Adarfuit VL6180 I2C anything They work together in Arduino Nano or Mega. Why is that? How can it be done? The STM32duino core IS NOT THE SAME as the official AVR core. As late as l...

Re: Linux Journal

I find Windows 7 a much better workhorse than W10. <...> IMHO, Win 8.1 when beaten into submission with numerous registry hacks is the better workhorse based upon my 2 years of experience with that distribution 4 years back (been on Linux exclusively for 2 years and would never go back to MS.
