Re: HsUSBD Proper Read-out method for Bulk-OUT EPs
Hi Kojima-san, According to HSUSB specification if Endpoint buffer have no enough space to store the one packet size, NYET will be returned. Allocate twice size memory (in your case 512K x 2 = 1K Bytes) to suppress the NYET/PING is correct way. To let the USB transfer more efficiency, I suggest usin...

Re: Related to Ethernet in M487
Hi alan.a, We integrated FreeRTOS with lwip (TCP/IP stack) on M480 BSP package, and lwip provide socket layer for network application, now we have two sample code [ TCP_EchoServer ] and [ UDP_EchoServer ], you can find these on M480BSP github. https://github.com/OpenNuvoton/M480BSP/ Or you can use t...

Re: [M453] Wakeup from Deep Sleep by GPIO Interrupt
Hi,
It seems you miss to enable wake-up function of timer.
To enable wake-up function of timer, you need to set the bit [WKEN] in the [TIMERx_CTL] or you can just call the API function TIMER_EnableWakeup(TIMERX).

Re: [M453] Wakeup from Deep Sleep by GPIO Interrupt
Hi,
Have you downloaded the BSP of M451 from our website, the BSP have the sample code of how to use GPIO to wake-up the system from the power-saving mode.
Thanks

Re: CAN wake up mechanism
It seems that you miss some instrument which let NUC442/NUC472 enter into power-saving mode.

Re: Sample project/resources for GCC/Linux
Hi,
As I know that NUVOTON actually have plan to let user develop their project under LINUX and it's still under development, so I can't sure when will it be released. But I'll give your request to them to speed up developing.
Thanks for your suggestion!

Re: Sample project/resources for GCC/Linux
Hi,
Unfortunately, NUVOTON doesn't have any tool to uploading the code to controller under LINUX for now, I think the best way is compile the source code and generate the HEX file or BIN file under LINUX and then use the "NuMicro ICP Programming Tool" under WINDOWS to upload the code.

Re: Sample project/resources for GCC/Linux
Hi,
The attachment file is a very simple project under GCC/Linux, maybe you could modify it to fit your develop environment.

Why is the observed variable displayed as “not in scope” in Debug mode under the Keil development environment?
When interrupted in Debug mode, the user wants to check the variable value but see ”not in scope” on the Watch window, as shown below: http://www.nuvoton.com/export/sites/nuvoton/.content/support/faq/images/FAQ103-1.jpg This is because the compiler would put variables into R1 registers after optimi...
