ST-Adapter Mode

Preparation:

A firmware to control the Arduino

TM

shields and communicate with the Raspberry Pi

should be programmed to the STM32 before hand; it can be generated from the project built in
CoIDE, and be programmed with CoIDE, CoFlash, or ISP tool. The source code to control the
Arduino

TM

shields are the same with those in the

STM32/Standalone Mode

, while the Protocol

Decode Layer code components (as shown in Figure 4-4) for communication with the Raspberry
Pi will be provided in CoIDE and this page.

The STM32 controls the Arduino

TM

shields, and the Raspberry Pi works as the GUI or command

line  console  to  send  commands/data  to  and receive  data  from  the  STM32.  This  is  an  advanced
mode  which  extends  and  strengthens  the  automation  control  capability  of  the  Raspberry  Pi,
taking  the  advantage  of  STM32F103  NVIC  (Nested  Vectored  Interrupt  Controller),  GPIOs,  and
more peripherals like ADC and PWM.
