[研究中]naze32(rev5) + FrSky X8R + MinimOSD + Bluetooth

Naze32 rev5
user manual

MinimOSD 設定
https://oscarliang.com/minimosd-micro-setup-naze32-pid-rssi/

Bluetooth 設定 - done

• 可以使用這個 http://ddddiy.blogspot.com/2014/02/hc-05-bt-module.html
• baudrate 設定有對應即可正常運作
• 直接接到版子中央的TX/RX pin(這邊應該就是轉USB port的hardware UART1)
• 這邊實際使用時發現Naze32 TX RX  是倒過來的，所以跟BT module 是TX-TX, RX-RX，跟一版接法不同

FrSky X8R

• 控制訊號
• PWM - done 
• 直接接channel 1-8
• 這樣由於pin被佔據，無法使用uart2/softserial/telemetry....
• https://github.com/cleanflight/cleanflight/blob/master/docs/Blackbox.md
• Pin RC3 on the side of the board is UART2's Tx pin. If Blackbox is configured on UART2, MSP can still be used on UART1 when the board is armed, which means that the Configurator will continue to work simultaneously with Blackbox logging. Note that inPARALLEL_PWM mode this leaves the board with 6 input channels as RC3 and RC4 pins are used by UART2 as Tx and Rx. Cleanflight automatically shifts logical channel mapping for you when UART2 is enabled in Ports tab so you'll have to shift receiver pins that are connected to Naze32 pins 3 to 6 by two.
• SBUS - 研究中
• Naze32 rev5 + FrSky X8R 需要SBUS 反向器，參考
• https://oscarliang.com/sbus-smartport-telemetry-naze32/
• 使用電晶體 http://skory.gylcomp.hu/alkatresz/bc547b.pdf
• 或是直接使用inverter http://www.ti.com/lit/ds/symlink/sn74lvc1g04.pdf
• telemetry - 研究中
• 需注意要使用SBUS, PWM gpio 被占據無法使用
• 參考 https://oscarliang.com/sbus-smartport-telemetry-naze32/
• RSSI- 研究中
