Gt911 Register Map Page

So, = (reg[0x8150] << 8) | reg[0x814F] Point 1 Y = (reg[0x8152] << 8) | reg[0x8151]

(read), though this can be changed during the reset sequence by toggling the INT pin. Auto-Increment: The GT911 supports continuous read/write gt911 register map

These registers control the operational state of the chip. So, = (reg[0x8150] &lt;&lt; 8) | reg[0x814F] Point

After power-up, the GT911 may not have valid config. You must upload a config blob: = (reg[0x8150] &lt

Reading from 0x8140 often returns the ASCII string "9110" . The firmware version is critical for determining which config registers are supported.
