Hello, Mike. I removed demo codes related to 2D drawing engine, Bouncing Balls, Mandelbrot and Bank Swap from the original file (attached for reference). Under the static code section, I removed #if TEST that include functions such as _cbWin, _DrawArcs, _TestArc and etc. Under MainTask_EnvisionKit, I removed everything and replaced it with the following code. void MainTask_EnvisionKit(void) { GUI_Init(); GUI_SetBkColor(GUI_BROWN); GUI_Clear(); GUI_SetColor(GUI_YELLOW); GUI_DispStringAt("Hello World!", 0,0); while (1) {} } I picked up the GUI_ commands to print "Hello World!" from emWin user guide. I ran the same code on SEGGER's window based simulation and got the output shown below. It would be great if the same can be displayed on RX65N Envision display. Thanks for your attention. I'm looking forward to your reply. Jason (Please visit the site to view this file)

Forum Post: Local variables declaration position in functions in CC-RL-V1.04
Hi All, I found that if the local variables don't declare at the beginning of the function, the compiler will output errors for the variables declaration. eg: void fun （void） { ICOV(0); u8 n_ltemp; n_ltemp = 0; . . . } will output error as followed: E0520268:Declaration may not appear after executable statement in block We need to do some code test, and the test will add some code before the variable declaration. Do you have some solutions for this issue? Is there any config in compiler CC-RL to fix this issue? Thanks! Ming

Forum Post: executing Halt instruction from RAM
hello everyone, i was trying to implement fast CRC in my RL78/I1B module. For that i purpose i was studying its datasheet and it states that in order to calculate CRC i have to execute HALT and RET instruction from RAm and don't know how to do that can any one please help. thanks

Forum Post: SDRAM in DK-S7G2
We're using DK-S7G2. We're not making use of SDRAM on SSP as of now. But in future if we want to use SDRAM for our application, what is the configuration we need to do? How we can make correct use of SDRAM? Is there an example already?

Forum Post: RE: How to generate fixed number of pulses using GPT
Thanks Rolf. Yes, I understood this. But because of limitations, (and because we already need two seperate GPT for independent pulse output), I think we can't go for other two timers. Can we do this without other timers?

Forum Post: RE: Overrun error, communication problems
In my application, overrun cannot be avoided because sometimes we disable interrupt for ram check. Since uart interrupt is not generated in overrun state, how can we clear the overrun flag to continue uart working.

Forum Post: RE: Overrun error, communication problems
Overrun cannot be avoided because some routines disable the interrupt. If overrun happens, uart receive stops as well as uart receive interrupt. Does it means that I must use another timer to check the overrun flag and re-initialize uart to cleare overrun flag?

Forum Post: RE: R8C, UART1 receive interrupt stops firing.
I think overrun cannot be avoided because I disable interrupt in some routine. The problem is that if overrun happens, it may result to uart stops. No new data receives and no receive interrupt. So how can I clear the overrun flag? Do I need to create a timer to monitor the overrun flag always?

Hi Matt, PHY is reset only once on initialization. I would not expect any side issues after removing this part of code. It's hard to tell if there are more incompatibilities, but it's reasonable to start modifying ether_phy.c/ether_phy.h only. Regards, adboc

Forum Post: RE: SDRAM in DK-S7G2
Hi GNK, If you're using DK-S7G2 BSP, you SDRAM is already configured. SSP has predefined macros that help placing variables/functions into specific sections. For example, to place a variable into .sdram section (placed in SDRAM memory region, see scripts/S7G2.ld linker script), you should declare the following: The variable can be used in your application as any other variable. If the project successfully builds, the resulting .map file (in Debug/ directory) should contain this entry: SDRAM memory region starts at 0x90000000, so it's placed in SDRAM. The resulting address of the variable might be different, but it should fall into 0x90000000-0x91FFFFFF. Regards, adboc

Sorry, in compiler version 1.04 there is no possibility. You have to upgrade to CC-RL V.1.06 and set the language option to "C99".

Forum Post: RE: R8C, UART1 receive interrupt stops firing.
A software that cannot avoid overrun looks not reliable to me. Just disabling the interrupt for a short time should not cause an overflow. To get an overflow you have to miss 2 interrupts. If you disable interrupts for such a long time you should consider if this is really necessary. I think that a minimum receive interrupt routine (read error, read receive data, write data to buffer, exit) can always be executed. You have to use interrupt nesting and the highest priority for receive interrupt.
