Description

The weighing port from the M5 Stack Series has a built-in 24-bit A/D-Chip HX711, specially designed for the electronic scales were developed.
The multiplexer selects either the differential input of channel A or B for the low-noise amplifier with programmable gain (PGA). Channel A can be programd with a gain of 128 or 64 what a differential input voltage of ±20 mV or ±40 mV equals, if a 5V supply to the analog voltage supply pin of AVDD is connected. Channel B has a fixed gain of 32. For the internal registers, no programming required. All the control elements of the HX711 are connected via the pins.
Connect, for example, to channel A a pressure sensor and then use the M5 core screen to the weight display data.
