+## Major update in 3-30-2021
+
+- Convert ASR650x series to a new branch;
+- Add ASR6601 series support and makes it as master branch;
+- Added and fixed some function to Arduino format, such as:
+ - `int analogRead(pin)` -- return adc level 0 ~ 4096;
+ - `float analogReadmV(pin)` -- return adc voltage in mV;
+ - *The ASR650x series ADC input pin range is 0 ~ 2400 mV*;
+ - *The ASR6601 series ADC input pin range is 100 ~ 1100 mV.*
+ - `SPI.begin(sck,miso,mosi,ss)` -- SPI begin;
+ - `wire.begin(sda, scl, frequency)` -- I2C begin;
+ - `Serial.begin(baud, config, rxPin, txPin)` -- UART begin.
