 The low-cost RDA5807MP is a single-chip broadcast FM stereo radio tuner with fully integrated synthesizer, IF selectivity, RDS/RBDS and MPX decoder. The tuner uses the CMOS process, support multi-interface and require the least external component. All these make it very suitable for portable devices.
 
 # Software
+## I²C Implementation
+The I²C protocol implementation is based on a crude bitbanging method. It was specifically designed for the limited resources of ATtiny10 and ATtiny13, but should work with some other AVRs as well. Due to the low clock frequency of the CPU, it does not require any delays for correct timing. In order to save resources, only the basic functionalities which are needed for this application are implemented. For a detailed information on the working principle of the I²C implementation visit [TinyOLEDdemo](https://github.com/wagiminator/attiny13-tinyoleddemo).

 ## Controlling the RDA5807
 The FM tuner IC RDA5807MP is controlled via I²C by the ATtiny. It has six writable 16-bit registers (addresses 0x02 - 0x07) and six readable 16-bit registers (addresses 0x0A - 0x0F). Since no data has to be read from the device for this application, only the writable registers are used. The RDA5807 has two methods of write access, a sequential one in which the registers are always written starting from address 0x02 and an indexed method in which the register address is transferred first and then the content. Both methods are determined by different I²C addresses. To transfer the 16-bit register content, the high byte is sent first. The RDA5807 is controlled by setting or clearing certain bits in the respective registers. The details of the meanings of the individual registers can be found in the data sheet. The current register contents are saved in the RDA_regs array.

 ## Main Function
 The code utilizes the sleep mode power down function to save power. The CPU wakes up on every button press by pin change interrupt, transmits the appropriate command via I²C to the RDA5807 and falls asleep again.
