.... i think the outside 22 hrs out of 24 feline may have forgiven me for the dose of frontline to the back of her neck. she stuffed herself on top of the book shelves, dropped down 2ft and then another 2ft, strolled across the wobbly bed tray/stand i use as a desk. groomed herself for a while and ...

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

Re: OV7670, Generic STM32F103RC and ILI9341 display

Yes. Just running the first part of code in Timer_setup() void TIMER_Setup(void) { gpio_set_mode(GPIOA, 1, GPIO_INPUT_FLOATING); timer_pause(TIMER2); // stop timer timer_init(TIMER2); // turn timer RCC on #define TIMER_RELOAD_VALUE 2 // must be adapted according to the results // as this mode is not...

Re: OV7670, Generic STM32F103RC and ILI9341 display

I tried using timer_pause(TIMER2); but it didn't help

I had to disable the DMA

(TIMER2->regs).gen->DIER = (0); // disable DMA request on TIM2 update

Re: OV7670, Generic STM32F103RC and ILI9341 display

I'm getting closer to a solution. The problem is (TIMER2->regs).gen->DIER = (TIMER_DIER_UDE); // enable DMA request on TIM2 update Seems to be somehow interfering with the SDFat If I disable the DMA on TIM2 update, I am able to save a image to SD. (TIMER2->regs).gen->DIER = (0); // disable DMA reque...

Re: OV7670, Generic STM32F103RC and ILI9341 display

Another update. It looks like the Timer setup code in the LiveOV7670 code void TIMER_Setup(void) { gpio_set_mode(GPIOA, 1, GPIO_INPUT_FLOATING); // Slave mode: Reset mode (see RM0008, chap. 15.3.14, page 394) // ------------------------ // The counter and its prescaler can be reinitialized in respon...
