7. Application Board
To demonstrate how useful microcontrollers can be for industrial solutions and in
common applications a hardware extension board – the Application Board – has been
developed. The picture below shows the Application Board.
Figure 21 : The Application Board
With its hardware components and their corresponding software drivers a lot of different
applications can be developed very quickly - without the common overhead of driver
development. The software developer can concentrate on developing algorithms for
solving specific problems instead of spending time in things that have been developed
many times before.
The Application Board package comes with a set of software modules to ensure short
development cycles and to give enough software samples that demonstrate the way of
developing embedded systems with Toshiba microcontrollers.
The software modules are:
• 4-bit bi-directional LCD-Panel driver
• I²C driver (I²C master protocol)
• LM 75 temperature driver
• SPI bus driver
• ST95040 serial EEPROM driver
• keyboard matrix input driver
• A/D conversion driver
• serial RS232 line driver
For all software modules the hardware components are available on the board and can be
tested directly.
Additionally there are some applications that uses the software modules to show how
more complex applications are to be developed. One of these examples is a digital
