Posted on January 11, 2013 at 18:51I have a project with OV7670 with stm32f4-discovery. My OV7670 has 16 pins and without fifo. And I don't have LCD. I hope I can use OV7670 to get view into stm32f4 and transmit data to smart phone and get the real ...
Posted on February 15, 2012 at 08:55Good day,I have some problem here, I took some code from another project, I rewrote some parts. But my camera do not want to work. I just want to read the ID of camera through I2C (or so called SCCB), but I always...
Posted on June 27, 2015 at 00:51Hi, when I use a peripheral with some unused pins, can I use other alternate functions of those pins (for other peripherals)? for example, in STM32f407, I use SPI2 with unused SPI2_NSS (pin 140). can I use this pin as...
Posted on June 27, 2015 at 17:52Just after I downloaded a program into Stm32F100 Discovery card, the STM32 ST-LINK Utility lost contact with the card. Now it cannot connect to it, no matter what I do. The software in the card is a plain GPIO test fr...
Posted on June 27, 2015 at 16:05Hi, i got a Nucleo F401RE Board and tried to update the flash with the internal bootloader, it works perfectly with USB<->RS232 bridge at 115200baud on UART1 (PA9,PA10), i got correct responses from bootloader, id, an...
