Re: OV7670, Generic STM32F103RC and ILI9341 display

Found 1 problem. Looks like SD leave SPI in 8 bit mode, but the ILI9341 lib needs 16 bit mode So I added a call to set into 16 bit before writing the text to the LCD, and it now saves the LCD screen multiple times #include <SdFat.h> #include "Adafruit_ILI9341_STM.h" #define TFT_CS PB0 #define TFT_DC...

Re: OV7670, Generic STM32F103RC and ILI9341 display

BTW. I have it wired like this lcd_sd_camera_blue_pill.png (Right click and view the image to get it in higher quality, as PHPBB seems to generate render views that are lower quality JPEG and I uploaded PNG) I'll double check that the SD_CS line and LCD_CS line are not somehow connected together. I'...

Re: Unverified user deletion

I've now delete all the unverified accounts which are more than 1 month old. I also did a spot check on some of the email addresses which were quoted, and they are normally gmail or hotmail etc, and when I tried to google those email addresses, most of the time google did not find a direct match. I ...

Re: Counterfeit F103s

Just in case anyone is interested, I purchased some STM32F103CBT6 parts from Arrow Electronics and from EBay seller polida2008. The Arrow price was almost $6, the EBay price was $1.90. I built a test fixture with a socket so I could verify them before soldering them in to anything, and all appear t...

Re: OV7670, Generic STM32F103RC and ILI9341 display

Hi Steve I don't understand why, but calling dma_disable(DMA1, DMA_CH2); dma_clear_isr_bits(DMA1, DMA_CH2); before using the SD lib didnt help. I still get the same problem and the SD card gets corrupted, I get a file on the SD, but the size is 0 and the name is some non- ASCII characters I definite...

Re: OV7670, Generic STM32F103RC and ILI9341 display

OK

I'll try that

BTW.
Currently after writing to SD, just re-enabling the Timer DMA enable does not start the camera running again, but if I have to completely re-init the timer and DMA etc that would be OK, as saving to SD is not a a quick process as it takes around 700mS
