Forum Post: RE: RTC open timeout
I have been able to get the same code to run properly on the S7G2-SK dev board. I am assuming that this must be a soldering issue on our PCB. Many thanks.

Hi Mk, You may use the same pins/driver as for the display. The display should be initialized first and once it's ready it will no longer need SPI communication, you can start communicating with the...

Hi, I configure 2 external interrupt, one to enter the Deep Standby Mode, the other to exit the Deep Standby Mode void g_external_irq10_callback(external_irq_callback_args_t * p_args) {...

Hi ppbinhminh, Did you have debugger attached? When it is connected and the device enters Deep Standby Mode, the connection may be lost. So after leaving this mode you may not see the application...

Hi Mk, Do you see what Ethernet and WiFi threads are performing when you don't get addresses resolved? You may take a screenshot of the call stack when the application is paused. Regards, adboc

Deep Software Standby Mode causes reset after exit and since the application has entered this mode in the ISR, the relevant interrupt flag might not be cleared. You may need to clear it in reset...

Thank adboc, I have problem with debugger attached before. I also the measured the MCU power consumption and I'm sure that the device enter the Deep Standby Mode. Everything is fine with Sleep Mode and...
View ArticleForum Post: r_flash_hp driver causes R_BSP_SoftwareDelay() to delay too long
I am using SSP v1.2.0 and the SK-S7G2 board. If I call R_BSP_SoftwareDelay() prior to calling g_flash0.p_api->.open() then it delays the expected amount of time. However if I call it after calling...
View ArticleForum Post: RE: r_flash_hp driver causes R_BSP_SoftwareDelay() to delay too long
Hello Jeff, When flash driver is open, flash cache is disabled (line 234 in r_flash_hp.c). At 240MHz, cache hit is 1 cycle and cache miss is 3 cycles, so the delay loop will run up to 3 times slower...

Hi Alan, Theoretically you may compute FFT using 'divide & conquer' algorithm and apply CMSIS DSP FFT routines to 4096-sized buffers. The description of the algorithm can be found here:...

Hi adboc! But the divide and conquer algorithm is the normal FFT algorithm if I don't recall incorrectly. Are you suggesting then that I will need some kind of external memory to store those 5ms's...

Hi there, I'm trying to run headless builds with e2studio 5.4.0 and SSP 1.2.0 and I find that only half the code is generated before the compilation starts. Actually, there's only the ' synergy '...
View ArticleForum Post: RE: CMSIS DSP Synergy Question
Hi Alan, Yes, it's the most popular one. You can compute the FFT of N-sized buffer by computing the FFT for two N/2-sized buffers ("even" and "odd") and then merge these results into one. I wonder...

Hello Bastien, Currently headless build does not support content generation - you will need to use GUI for this (e2studio or SSC). Regards

Hi adboc, If I'm not mistaken, the library does a pretty efficient job with the FFT, as it formats the output as real and imaginary components of DC, fundamental frequency, first harmonic, etc......

Thanks Karol for your response. However, inserting open() and close() around all of my Data Flash reads and writes is not a very elegant solution. Would a cleaner solution be for the driver to handle...

Hello Jeff, You don't need to open the flash driver to read the data flash - you can access this memory using address pointers from 40100000h to 40110000h. SSP 1.1.x and earlier did not disable the...
