SPARKY - Adding documentation.
2014-12-10 08:54:44 -08:00
# Board - Sparky
The Sparky is a very low cost and very powerful board.
* 3 hardware serial ports.
STM32F3 - Support hardware serial inversion. Tested on the Sparky board with an FrSky X4RSB without external hardware inverter.
2014-12-26 04:10:27 -08:00
* Built-in serial port inverters which allows SBUS receivers to be used without external inverters.
SPARKY - Adding documentation.
2014-12-10 08:54:44 -08:00
* USB (can be used at the same time as the serial ports).
* 10 PWM outputs.
* Dedicated PPM/SerialRX input pin.
* MPU9150 I2C Acc/Gyro/Mag
* Baro
# Status
Flyable!
Tested with revision 1 board.

* Baro - detection works but getting bad readings, disabled for now.

* Sonar
* Display (via Flex port)

* Softserial - though having 3 hardware serial ports makes it a little redundant.
# Flashing
## Via USART1
SPARKY - Adding note regarding the TauLabs bootloader.
2014-12-10 08:58:23 -08:00
Short the bootloader pads and flash using configurator or the st flashloader tool via USART1.

Unshort bootloader pads after flashing.
## Via SWD
On the bottom of the board there is an SWD header socket onto switch a JST-SH connector can be soldered.
Once you have SWD connected you can use the st-link or j-link tools to flash a binary.
See Sparky schematic for CONN2 pinouts.

## TauLabs bootloader
Flashing cleanflight will erase the TauLabs bootloader, this is not a problem and can easily be restored using the st flashloader tool.

# Serial Ports
| Value | Identifier | RX | TX | Notes |
| ----- | ------------ | --------- | ---------- | ------------------------------------------------------------------------------------------- |

| 2 | USART1 | RX / PB7 | TX / PB6 | Conn1 / Flexi Port. |
| 3 | USART2 | RX / PA3 | PWM6 / PA2 | On RX is on INPUT header. Best port for Serial RX input |

| 4 | USART3 | RX / PB11 | TX / PB10 | RX/TX is on one end of the 6-pin header about the PWM outputs. |
Update Board - Sparky.md I was confused by the USB VSP ( Virtual Serial Port) at the bottom. I believe you meant USB VCP correct?
2014-12-13 19:38:06 -08:00
USB VCP *can* be used at the same time as other serial ports (unlike Naze32).
STM32F3 - Support hardware serial inversion. Tested on the Sparky board with an FrSky X4RSB without external hardware inverter.
2014-12-26 04:10:27 -08:00
All USART ports all support automatic hardware inversion which allows direct connection of serial rx receivers like the FrSky X4RSB - no external inverter needed.
