Topview Simulator
Code Generation Facilities
Using this, you can generate required assembly / C
code for all possible on-chip peripheral
functions and also many external peripheral functions. You can include these routines into
your program.
You can do this in few simple steps. You keep open your editor and point the desired
location using the cursor and then configure the peripheral function in the respective
dialog box.
That's all. Now you press the code generate button to get the required assembly
/ C code at
the defined place. Suitable comments are also made available for easy understanding. Then
keep going with your target program flow.
Benefit: You are assured of fully tested and compact assembly
/ C codes which can be
directly used in your target applications.
Internal Peripheral Functions
Serial Port
- Any one of the modes 0/1/2/3 can be selected.
- Depends upon the mode, crystal, the possible baud rates will be displayed for your
convenience.
- Timer 1 or 2 can be selected for baud rate generator.
- Initialization, transmission and reception routines will be generated according to the
given selection.
External Peripheral Modules
You can generate code snippets suitable for interfacing variety of external LED and LCD
modules. You can activate a dialog box and define your exact needs by clicking relevant
settings. You can use any available I/O lines for interfacing these modules. There is no
restriction like using port lines (of same port) in order to get a LED/LCD function. Any
I/O line from any port can be used to configure the required display function.
LED Display Functions
- 1 / 2 / 4 Digits
- Multiplexed / Non Multiplexed.
- Common Anode / Cathode.
- Data Input options : BCD / 7 segment.
- Use of external multiplexer.
You can also notice the allotment of I/O lines to get the required LED function in the
same dialog box.
LCD Module Selection
Just like LED options, you can make use of many possible modules suitable for LCD
interfacing.
- LCD Type : 1 line X 16 Characters, 2 X 16 , 4 X 16 and 4 X 20.
- Interfacing options : 8 bits / 4 bits.
- Facility to keep same settings as you tried in simulator.
- All possible routines meant for LCD interfacing.
The dialog box gives all possible options. Just click your requirements and get the
relevant assembly code.
Keyboard Interfacing
Using this facility, you can generate the required code for following key matrices:
You also can define internal data memory location where you want to get the keyboard
code.
You can use same simulator settings.
Use any port line to implement this key matrix.
I2C / SPI Buses
The Topview Simulator gives tight and right assembly code to implement all possible
peripheral functions as shown in the following diagrams.
