20. Hands on 2. E2Studio with Applilet integration
Your task
Get the Red/Green and Amber LED’s to flash alternately at ½ second interval….
Hint:
Modify “Applilet” Peripheral Function settings
Port4.1 amber LED to startup “ON”
Compare match timer interval value 250mS

21. Hands on 2. E2Studio with Applilet integration
Now lets make a variable LED flash rate.
Enable the ADC in C/C++ perspective
Continuous scan mode
ANO00 channel
Software trigger
Data placement :Left alignment,
so the data is in the 12 MSB’s of the 16 bit register.
Disable interrupt

22. Hands on 2. E2Studio with Applilet integration
Now lets make a variable LED flash rate.
Modify r_cgc_main.c to start the ADC, add these after line 76.
/*Start ADC*/
R_S12ADb_Start();
Modify r_cmt_user.c to copy the ADC result for ANO00 to the CMT compare register, add these after line 75.
/*copy ADC result to CMT compare register */
CMT0.CMCOR = S12AD.ADDR0;

23. Hands on 2. E2Studio with Applilet integration
Rebuild , debug and run..
The LED’s should change flash rate based on potentiometer setting !
See how much memory has been used.
WindowShow ViewMemory Usage
Percentage < 75% : Colour of bar is Green
75% <= Percentage <90% : Colour of bar is Orange
Percentage >= 90% : Colour of bar is Red

24. Hands on 2. E2Studio with Applilet integration
Now lets add a Visual Expression Gauge to see the ADC value graphically.
Declare a variable in r_cg_main.c, line 55
volatile unsigned int adc_val;
Make the variable equal to the ADC result in the main while loop.
adc_val=S12AD.ADDR0 ;

25. Hands on 2. E2Studio with Applilet integration
add the Visual Expression Gauge to e2Studio
WindowShow ViewVisual expression
Drag Gauge to display window
Right click and set the expression values
Build, download and run the code.
The dial should respond when the potentiometer is turned.

Run the code !
Connect a mini-USB cable to CN1 and a Windows PC. The RPB will be detected and HID drivers installed.
Launch the RSK_HID.exe application, which can be found in USB_PHID root project folder.
C:\Renesas\workspace\RPB\RX111\USB_PHID
Click the 'Connect'button and use VID = 0x0000 and PID = 0x0003.

36. Hands on 4 USB Host Run the demo !
Compile and download the sample code to the target, run, then disconnect the debugger.
Connect a mini-USB cable to CN1 and a USB host. LED1 will illuminate and the supercapacitor will begin to charge.
After several seconds LED1 will go out and LED0 will illuminate. The supercapacitor is now charged. Disconnect the USB cable.
LED0 will blink periodically to show the board has power.
Connect a blank FAT/FAT32 formatted USB stick to CN2.
LED2 will light, as will the activity light on the USB stick (if present), then all LEDs will go out and the MCU will enter power save.
Connect the USB stick to a PC, and observe the file RX111.pdf, containing a page of the MCU datasheet.
To repeat the sample, reconnect to CN1, press the reset button to recharge the supercap. Go to step 3.
