Re: Multiple I2C libraries

You can try adding similar check points: void setup() { Serial.begin(115200); while (!Serial) ; // wait for a serial connection via USB delay(1000); Serial.println("SSD1306 begin"); // check point display.begin(SSD1306_SWITCHCAPVCC, 0x3C); display.display(); delay(2000); Serial.println("VL begin"); ...

Re: STM32-RFM69

Asking again: which core do you use? Arduino_STM32 or the STM32DUINO?

The library you pointed to, I'm using it with Moteino and RFM69HW and it works flawlessly.
I think you should use the same library which is working.
Please also post a simple test sketch to reproduce the problem.

Btw, which core do you use? The Arduino_STM32 or the STM32DUINO core?

Re: usb host contr stm32

Have you ever considered to use a CH376 module? It interfaces directly a USB stick, so you don't need USB host functionality.

I have tested one of these and it really works, but do not expect high access speed.

Re: Multiple I2C libaries

Put some serial output lines to detect which is the line where the sketch hangs.

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

Do you power the board from the USB? If so, then no wonder, because the serial USB is started and working in the background.
If you don't need USB serial, then you should remove the compiler directive "-DSERIAL_USB" from the boards.txt line corresponding to the plue pill.

Re: Library to create bitmap fonts Adafruit GFX fonts

Just a short question:
What is Advance X?
Advance X seems to be always (Width -1). Can't be automated always to width -1 (no reason to display it)?

Re: Library to create bitmap fonts Adafruit GFX fonts

Ah, I simply did not select anything in the left list.
As soon as I select something, it will be displayed.
So it works.
Thanks.
