Temp error / USB error #77

My Tinybee is not able to show temperature correctly (EXT1,EXT2,BED are usually between 0° and 5° instead of 19°/20°), while when I warm up bed at 60°, I have a real temp between 59,5° and 61 (so it's ok). In Hal.cpp I have : HAL_adc_result = mv * 1023.0 / 2570.0;

In addition, when I connect the printer by USB, Cura (but also Repetier host) doesn't find it (but I can upgrade firmware by Visual Studio Code by USB, so it works!).... it's no so important, because I can use wifi, but I can't understand why my Tinybee do it...

The temperature list of low temperature has some deviations corresponding to the voltage, so there may be deviations when the temperature is below 20 degrees, but it is correct if the temperature is above 20 degrees. Your usb cannot be connected. Is your serial port configured at 0?
