Blueseries simonk uart firmware

This firmware uses the serial connection from FC to ESC. It uses the original konze uart protocol at 38400 baud.
Protocol is:
- syncbyte 0xF5
- one byte throttle value for esc 1 range 0 to 200.
- one byte throttle value for exery other esc

Example message for 2 motors, zero throttle: 0xF5,0x00,0x00
Example message for 4 motors, mid throttle: 0xF5,0x64,0x64,0x64,0x64

The firmware is bs_nfet type, tested with hk blue series 20A and hk 20A ubec.
It should work with every bs-nfet esc where int0 is connected to rxd.

Yes, i have flown this. Old dji F450 frame, blue-series esc, multiwii FC. See attached picture. All pwm pins empty.
I can provide output driver for avr multiwii or stm32 baseflight.

Attached Simonk/konze uart firmware bs-nfet with icp and int0 disabled, bootloader enabled, uart enabled.
Comes with 4 different motor ID's.
When programming with built-in bootloader you need the "bs_nfet_uart_noboot" version.
If you want source ask me, i provide.

Attached processing test program for mot1 and mot2 named rcsim.
