#Introduction The main goal of this project is to add diversity to an already amazing feature set. Please see the following video for a quick intro of the project. [](http://www.youtube.com/watch?v=NwnQCUikqvI) The code is also now backward compatible with the original rx5808-pro schematic minus diversity and dip switch mode. For details on updating click [here](/docs/diy-arduino-nano.md). This project originated [here](https://code.google.com/p/rx5808-pro/) and has been modified to include diversity receiver menu. ## Donations Welcome! **Help fund more research and development into these great open source projects.** [](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=GE83PG4KBZ5NJ) Donations help show the developer your appreciation for all their hard work. A little goes a long way whether it is used for new hardware samples or better test equipment, you can be sure it will be put to good use. ## Table of Contents 1. [Features](#features) 2.

[License](#license) ##Features - **User control** - 3 Button navigation, up, down, select. - **Manual Mode** - Set channel manual - **Search Mode** - Search next channel based on RSSI - **Scanner** - Print spectrum of all 40 channels - **Save mode** - Save startup mode (manu, seek, scan) - **Save channel** - Startup with last saved channel - **Beeper** - Acustic feedback on important actions - **Save RSSI range** - RSSI voltage may vary per part - *(NEW)* **Quick Save** - From any home press and hold select for 1 second. - *(NEW)* **Diversity** - Receiver select and monitor. - *(NEW)* **Led Status** - Power, button pressed, active antenna. - *(NEW)* **Race Band** - Added band C/Immersion Race for a total of 40 supported channels. - *(NEW)* **Backward Compatibility** - Use this code with your existing setup. - *(NEW)* **OLED Version** - Use a 128x*** OLED Display instead of TV_OUT. - *(NEW)* **Setup Menu** - Creating menu for toggling settings. - *(REMOVED)* ~~**DIP mode** - Set channel by extern DIP switch~~ ##Usage ####Screens  1. **Mode Select** - Use the up/down buttons to navigate. Hit mode to select. Don't press anything to return to the last mode selected. 2. **Auto Scan** - Scans all bands until a signal with good signal strength is found. 3. **Manual Mode** - Will hold on a manualy selected channel. 4. **Band Scaner** - Scans all bands and presents them with a sitnal strength bar graph. 5. **Diversity** - Select which receiver to use or auto. Also Displays signal strength of each antenna. 6. **Setup Menu** - Saves last used channel and mode for next power cycle. This is also where you enter RSSI calibration mode. 1. **ORDER** - Change the Manual Mode channel seek order by frequency or channel number. 2. **BEEPS** - Turn beeps on or off. 3. **SIGN** - Edit your call sign. ( OLED Only ) 4. **Calibrate RSSI** - Calibrate the min and max RSSI values. 5. **Save & Exit** ####Initial Setup When powering on for the first time it is best to calibrate your RSSI. To do this follow these steps below. (You can repeat this process as many times as needed for best results.) 1. Power on your receiver and transmitter and place them about 10 to 20 feet apart from one another. (If you are using directional antennas make sure they are pointed at your transmitter for best results.) 2. Next navigate to the "Setup Menu". 3. Next navigate to "Calibrate RSSI". 4. Now that you are in the RSSI calibration screen, the receiver will scan all channels 3 times getting the min and max RSSI strength. 5. Once all 3 scans are complete you will be returned to the last home screen. You should now be able to have accurate RSSI readings and also auto scan to active channels. ##Hardware This project is centered around the rx5808 5.8ghz receiver module which can be found at a number of online stores. I have modified the original schematics to incorporate the diversity setup. I have also added LEDs to represent which antenna is currently being selected.  For more information on specific hardware implementations: 1. [DIY Simple - Arduino Nano](/docs/diy-arduino-nano.md) 1. [DIY Intermediate - Custom Board (T-Box)](/docs/diy-through-hole-board.md) 2. [DIY Advanced - Custom Board](/docs/diy-custom-board.md) 1. [OLED Version - Arduino Nano](/docs/oled-arduino-nano.md) 3. [rx5808 SPI modification](/docs/rx5808-spi-mod.md) ##Software The major software changes are centered around the diversity menu. This required removing the dip switch mode from the origional project. Within the diversity menu you will find RSSI signal strength for each receiver and the ability to select which mode the receivers are operating in (Auto, Receiver A, Receiver B). The following values control how often we switch receiver in diversity auto mode. ``` // rssi strenth should be 2% greater than other receiver before switch. // this pervents flicker when rssi values are close and delays diversity checks counter. #define DIVERSITY_CUTOVER 2 // number of checks a receiver needs to win over the other to switch receivers. // this pervents rapid switching. // 1 to 10 is a good range. 1 being fast switching, 10 being slow 100ms to switch. #define DIVERSITY_MAX_CHECKS 5 ``` The diversity switching logic is simple. ``` If Receiver A is greater than Receiver B by two percent check_counter-- // receiverA win else check_counter++ // receiverB win If check_counter is zero Set receiverA as active receiver. If check_counter is DIVERSITY_MAX_CHECKS Set receiverB as active receiver. ``` The two percent helps prevent rapid video switching when both RSSI are close in value.  ##Contributing Any contributions are welcome!
