### Prepare the Arduino IDE:
1. In order to compile successfully you need also to modify a maple library file. In ```....\hardware\Arduino_STM32\STM32F1\cores\maple\libmaple\usart_f1.c``` comment out the 2 functions as shown below. This is required to have low-level access to the USART interrupt. <br>
```C
```
/* void __irq_usart2(void){
usart_irq(&usart2_rb, USART2_BASE);
}

#### Option 2: Flashing with USB cable.
This method use USB connector on the STM32 V1.0 board or on the maple clone board.
1. Install first maple USB driver by running the batch file found in Arduino STM32 package folder "..\hardware\Arduino_STM32\drivers\win\install_drivers.bat"
1. Install first maple USB driver by running the batch file found in Arduino STM32 package folder ```..\hardware\Arduino_STM32\drivers\win\install_drivers.bat```
1. Download the free STM32 flash loader demonstrator from [ST.com](http://www.st.com/en/development-tools/flasher-stm32.html) and using a USB-TTL device (like FTDI cable) flash the STM32duino bootloader available from Roger Clark's great STM32 site [here](https://github.com/rogerclarkmelbourne/STM32duino-bootloader/tree/master/STM32F1/binaries) .Use bootloader **generic_boot20_pa1.bin**
1. Open Arduino IDE,browse to multiprotocol folder,load the sketch multiprotocol.ino.
1. In Arduino IDE under "Upload method" select **STM32duino**-bootloader.Click upload ,wait until upload is complete.

## Flashing precompiled binaries:
If you want to flash a pre-compiled binary file (like the Release .bin files) you need specialized software and the same FTDI cable setup already posted [here](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/docs/Compiling_STM32.md#option-1-flashing-with-tx-powerhighly-recommended).
If you want to flash a pre-compiled binary file (like the Release .bin files) you need specialized software and the same FTDI cable setup already posted [here](Compiling_STM32.md#option-1-flashing-with-tx-powerhighly-recommended).
1. Set BOOT0 jumper(skip this step if you aready made your own cable ,see above)
1. Connect your 3.3V FTDI cable (USB - TTL serial) to Multiprotocol serial port (RX,TX,GND pins when flashing with TX power).
