ST / Mbed 2 deprecated HelloWorld_IDS01A4

HelloWorld_IDS01A4 mbed application for Spirit1 P2P demo.

Dependencies:   mbed

Fork of HelloWorld_IDS01A5_Program by rosarium pila

mbed 2.0 (a.k.a classic) HelloWorld example for Spirit1 to transfer data from one node to another.
To send the predefined data packet from the sender to the receiver, user needs to press User Button on the board. The LED on the receiver expansion board will toggle on reception of data successfully.
Data packets sent and received can be seen on USB serial terminal.

+# Prototype RF Driver for STM Sub-1 GHz RF Expansion Boards based on the SPSGRF-868 Module for STM32 Nucleo #
+
+Currently supported boards:
+ * [X-NUCLEO-IDS01A4](http://www.st.com/content/st_com/en/products/ecosystems/stm32-open-development-environment/stm32-nucleo-expansion-boards/stm32-ode-connect-hw/x-nucleo-ids01a4.html)
+
+**Note**, in order to use expansion board `X-NUCLEO-IDS01A4` in mbed you need to perform the following HW modifications on the board:
+ * **Un**mount resistor `R4`
+ * **Mount** resistor `R7`
+ 
+Furthermore, on some Nucleo development boards (e.g. the [NUCLEO_F429ZI](https://developer.mbed.org/platforms/ST-Nucleo-F429ZI/)), in order to be able to use Ethernet together with these Sub-1 GHz RF expansion boards, you need to compile this driver with macro `SPIRIT1_SPI_MOSI=PB_5` defined, while the development board typically requires some HW modification as e.g. described [here](https://github.com/ARMmbed/sal-nanostack-driver-stm32-eth)! 
+
+This driver can be used together with the 6LoWPAN stack (*a.k.a.* Nanostack).
