PCF8574(uint8_t 0x38); must be 1. PCF8574((uint8_t) 0x38); or 2. PCF8574(0x38); uint8_t is a type so that is why the compiler expect a typecast at this position, see my 1. example - (uint8_t). Actually you don't need this so example 2. without the typecast is enough. A typecast is to force a type of value to be of a specific type. Google C++ typecast.
