Description
26
Display circuit is composed of a 98*64 resolution LCD module and a
display supply voltage bypass capacitor C34. The power of LCDM is
supplied from VR2. It is controlled by U1 via I2C bus: SCL and SDA.
The data rate of I2C is programmed to 400KHz. NRESTOUT is low
active to reset all LCD registers. The LCD Module is adopted with
COG (chip on glass) type, and default display supply voltage VLCD at
normal temperature is 7.6V. R27 is used for ESD protection and C50,
C51 are used for radiation suppression.
