Hey, guys. Can anyone help me with something? In my project, I would like to display the distance data from the laser sensors vl53IoX on the SH1106 display. To control the display I use U8g2lib.h library. Everything is controlled via rp2040, which has two I2C buses. Sensors are connected to the I2C0 bus on pins 5 and 8 and display to the I2C1 on pins 14 a 15. I am programming it through Arduino IDE. I would like the sensors to be on one bus and the display on the other. I have a minor problem with the display functioning on the second I2C1 bus.
If I am using the SW I2C bus (I2C1, pins 15 and 14), sensor data or Hello World is displayed on the screen, but with the wrong display rendering.
U8G2_SH1106_128X64_NONAME_1_SW_I2C u8g2(U8G2_R0,15,14,U8X8_PIN_NONE);
If I am using the HW I2C bus (I2C0) on predefined pins 4 and 5, the display works only with Hello World, not with sensors, but rendering is okay.
U8G2_SH1106_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, U8X8_PIN_NONE);
Here is the code, I need help setting it to use the second bus I2C1 on the pins I need (14 and 15) and to render the display normally. I will be grateful for any advice. Thanks
