Re: Multiple I2C libraries

Have you tried the i2c_scanner example when both are connected?
Are they connected to the same I2C lines?

Have you tested the Adafruit OLED example? https://github.com/adafruit/Adafruit_VL ... x_oled.ino
It seems that it is using the same ICs as you.

Re: Multiple I2C libraries

You should use directly the PWM output signal of timer instead of digital port output.
Add this line to setup() to generate PWM signal on a timer channel pin:

Code: Select all

pinMode(OUTPUT_TIMER_CHANNEL_PIN, PWM);

Re: Hello from Philippines

You have to connect a USB cable from PC to the micro USB slot of the blue pill.
The Stlink is just for upload, but it does not have serial com port.

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?
