2. Introduction
2. Introduction
This manual is designed to answer, in tutorial form, the most common questions asked about using a Renesas
Starter Kit (RSK). The tutorials help explain the following:
•
How do I compile, link, download and run a simple program on the RSK?
•
How do I build an embedded application?
•
How do I use Renesas’ tools?
Files referred to in this manual are installed using the project generator as you work through the tutorials. The
tutorial examples in this manual assume that installation procedures described in the RSK Quick Start Guide
have been completed. Please refer to the Quick Start Guide for details of preparing the configuration.
These tutorials are designed to show you how to use the RSK and are not intended as a comprehensive introduction to
2
e studio, the compiler toolchains or the E1 emulator. Please refer to the relevant user manuals for more in-depth
information.
2.1
Code Generator Plug in
The Code Generator plug in for the RL78/G1G has been used to generate the sample code discussed in this
2
document. Code Generator for e studio is a plug in tool for generating template ‘C’ source code and project
settings for the RL78/G1G. When using Code Generator, the engineer is able to configure various MCU
features and operating parameters using intuitive GUI controls, thereby bypassing the need in most cases to
refer to sections of the Hardware Manual.
Once the engineer has configured the project, the ‘Generate Code’ function is used to generate three code
modules for each specific MCU feature selected. These code modules are name ‘r_cg_xxx.h’, ‘r_cg_xxx.c’,
and ‘r_cg_xxx_user.c’, where ‘xxx’ is a three letter acronym for the relevant MCU feature, for example ‘adc’.
Within these code modules, the engineer is then free to add custom code to meet their specific requirement.
Custom code should be added, whenever possible, in between the following comment delimiters:
/* Start user code for adding. Do not edit comment generated here */
/* End user code. Do not edit comment generated here */
Code Generator will locate these comment delimiters, and preserve any custom code inside the delimiters on
subsequent code generation operations. This is useful if, after adding custom code, the engineer needs to revisit Code Generator to change any MCU operating parameters.
2.2
Note Regarding Source Code
Due to the project generator, it is possible that line numbers for source code illustrated in this document do not
match exactly with that in the actual source files. It is also possible that the source address of instructions
illustrated in this manual differ from those in user code compiled from the same source. These differences are
minor, and do not affect the functionality of the sample code nor the validity of this manual.

Build Configuration
2
The e studio workspace will be created with two build configurations: ‘HardwareDebug’ and ‘Release’.
Release
This build mode has optimisation turned on, and provides little debug information. The C code execution may
appear to be out of order, due to the way compiler optimises the code. This build configuration is intended for
final ROM-programmable code.
HardwareDebug
This default build mode has all optimisation turned off, and provides full debug information. This is the best
configuration to use whilst developing code as C code execution will be linear.
•
Click the top level ‘Tutorial’ folder again,
and then the arrow next to the build
button (hammer icon),
and
select
the
‘HardwareDebug’ option.

This section will look at each section of the tutorial code and basic debugging functionality in e studio.
4.1
Program Initialisation
Before the main program can run, the microcontroller must be configured. The following parts of the tutorial
program are used exclusively for initialising the RSK device so that the main function can execute correctly.
The initialisation code is run every time the device is reset via the reset switch or from a power cycle.
•
Build and download the code as shown in
Section 3.3.
•
On the Project Explorer tab expand the
‘Tutorial’ folder by clicking on the arrow
next to the folder icon, as highlighted by
the red circle.
•
Click the arrow next to the ‘src’ folder to
show the source files.
•
Expand the ‘src’ folder in the same way
click
on
and
double
‘r_cg_hardware_setup.c’ to open the file.
•
Breakpoints can be set by double clicking
at the left-hand edge of the source
window. On the line with instruction
R_Systeminit(), double click next to the
vertical line to set a breakpoint.

4. Reviewing the Tutorial Program
Main Functions
This section will look at the program code called from with the ‘main' function, and how it works. It is
necessary to connect the RSK RL78G1C-USB connection to a PC USB port and open a terminal emulation
program, such as TeraTerm, with the settings 19200, 8, N, 1. For information on installation of the RSK virtual
2
COM port driver, refer to the file ‘Description.txt’ in the e studio Tutorial project.
The program code performs the following tasks:
•
•
•
•
•
Initialises the LCD display.
Writes some information to the display.
Sets up UART1 to receive data by passing it a location to store received data and the length of the
received data.
Enables UART1 operations.
Enters an infinite loop, which checks to see if SW3 has been pressed or a ‘c’ or ‘C’ character has
been received from the PC and if so it will request a new A/D (analog to digital) conversion of the
potentiometer value. The ADC value is then displayed on the LCD and on the PC. In addition a
modulo 16 counter is maintained that counts the number of requested ADC conversions. The count
results are displayed on the PC and they are also represented on LEDs 0 to 3.
Let us now follow this flow by setting some breakpoints in the code.
•
Right
click
the
‘R_UART1_Receive’ function
call and select ‘Run to Line’
to execute the program up to
this line. The ‘init_lcd’
function call configures the
LCD
module,
and
‘display_lcd’ will write the
text between the double
quotes to the display.
•
Set a breakpoint on the
‘R_UART1_Start()’ function
call by double-clicking in the
breakpoint column.
•
Click the ‘Step Into’ button to
step
into
the
‘R_UART1_Receive()’
function.
R20UT3023EG0100 Rev. 1.00
Jan 08, 2015
Page 16 of 24
RSKRL78/G1G
•
The program counter should
now
move
into
the
R_UART1_Receive function
definition. This function is an
API function provided by the
Code Generator. It sets up
the UART interrupt handler
code to receive a specified
number of bytes into a
receive buffer.
Once the
specified number of bytes
has been received, the
interrupt handler code calls a
callback function as shown
later on in this section.
•
For full details on how to
create a project using the
Code Generator refer to the
Code Generator Tutorial
Manual.
•
Click the ‘Resume’ button to
resume program execution.
•
The program counter
should come to a halt at
the
R_UART1_Start
function.
•
Step over the function by
clicking the ‘Step Over’
button.
Alternatively,
press [F6].
4. Reviewing the Tutorial Program
The
R_UART1_Start()
function enables the UART
interrupts.
The program then proceeds
to the main while() loop. The
code inside the loop waits for
user input from either the
UART or RSK switch SW3,
and then performs an A/D
conversion.

•
Locate the function call to
‘display_lcd’ inside the
while loop.
•
Set a breakpoint on the
‘display_lcd’ function call
by double-clicking in the
breakpoint column.
•
In the Project Explorer
pane, locate the file
‘r_cg_sau_user.c’
and
double-click to open the
source file. Scroll down
to
where
r_uart1_callback_receive
end is defined (not where
it is being called from).
•
Set a breakpoint on the
line of code inside the
r_uart1_callback_receive
end function as shown
opposite.
•
Continue to execute the
program by clicking the
‘Resume’ button.
•
In the terminal emulation
window, press the ‘c’
button on the keyboard.
•
The program will halt at
the breakpoint in the
r_uart1_callback_receive
end function as shown
opposite. Remove the
breakpoint by doubleclicking on the breakpoint
column.
•
Continue to execute the
program by clicking the
‘Resume’ button.
•
The program will halt at
the breakpoint in the main
while loop.
•
Remove the breakpoint
by double-clicking on the
breakpoint
column.
Continue to execute the
program by clicking the
‘Resume’ button.
