Now, it's stuck on the postbuild_img2_arduino. That makes sense. -rwxr-xr-x 1 steve steve 83908 Sep 6 09:05 postbuild_img2_arduino_mac -rwxr-xr-x 1 steve steve 1304864 Sep 6 09:05 postbuild_img2_arduino_windows.exe

I'm trying to run Ardunio with Ameba Board and RTL00 (RTL8710) on x64 Linux. To install, I have modified the board .json file, simply added ameba_tools block for x64.pc-linux https://raw.githubusercontent.com/kissste/Ameba.x64.linux/master/package_realtek.com_ameba_index.json Unfortunately...

I'm having trouble with toggling CS pin when running SPI in DMA mode. It does not toggle/switch CS when if I keep supplying continuous DMA stream (on an interrupt send a next DMA). I would like it be able to specify that I want it switch/toggle CS once one DMA transfer is finished. The only...

It needs to somewhat fit one of these: VGA Signal Timing given that we go 41.333MHz or 1/2 of it = 20.666MHz but, can't be below 25MHz based on the VGA spec. so we are stuck with 41.333MHz suitable are: VESA 640x480@100 Hz (pixel clock 43.16 MHz) VESA 768x576@72 Hz (pixel clock 42.93 MHz)...

yes, 4-bit would be quite a lots of memory

Thank you

Runs resolution 800x600 @63Hz at Pixel frequency 41.33MHz. Using 2 SPIs channels - one for video signal, second one for H-Sync One GPIO for V-Sync GitHub - kissste/rtl8710_VGA_Display_Driver: VGA Driver for RTL8710, RTL8711 and RTL8195 SoC https://goo.gl/photos/ztxVsQsS6xFEcsJM6

Bit banding (feature of Cortex M3) works well, as expected. @166.66MHz CPU gpio_write 1, and then gpio_write 0 takes ~0.57us gpio_write(&gpio_ledC3, 1); gpio_write(&gpio_ledC3, 0); Bit-Banding =1, and then Bit-Banding = 0 takes ~0.17 us GPIO_C3 = 1; GPIO_C3 = 0; #define BITBAND_PERI_REF...

in i2s_freertos.c: if (rate<=48000 && lockBitcount) { #if defined(PWM_HACK) || defined(DELTA_SIGMA_HACK) rate <<= 1; result = 1; #endif } I2S can't be oversampled

RTL8711AF does not have external SPI RAM, only RTL8711AM does. This MP3 decoder is not using external SPI RAM. The code allocates 50K of internal RAM as a buffer. I think, RTL8711AF will work just perfectly fine with this code. RTL8711AM - I don't know. It might be OK too, depends on how...
