Wire.requestFrom

[aleknest]

Hi. Have troubles in Marlin with Wire.h

Wire.requestFrom (addr,len); if (Wire.available()>=0) { SERIAL_ECHOLN("available");

I never see "available". This code work perfect on mega2560

Thanks for the information, I'l look into it, this isn't really a general Arduino framework, just designed for Marlin, but I'm pretty sure some people have used I2C devices with it.

I can share master modules (Marlin, SKR 1.3, PlatformIO) and slave project(Self maded, Arduino nano, PlatformIO). If it necessary, of course

I2C OLED ssd1306 displays work fine on marlin on lpc1768 using this (It was also a SKR 1.3)
