Posted on July 11, 2012 at 00:52Hi, I have a problem with interfacing OV7670 camera. I connect only 4 wires from Ov7670 to my stm32f4board, SIO_C, SIO_D, 3V+ and GND. Then I tried to read product id of the camera. It always send 0xFF. I am n...
Posted on April 08, 2014 at 04:11 Guys, I have OV7670 module and STM32 dev board, I'm confused on how to connect the port of STM32 and OV7670 at the module because of the name of the port on OV7670 is different with in STM32 code, ...
Posted on April 17, 2015 at 12:48Hello again! I would like to make a question about an issue I have with the measurements of three currents! Specifically I have a 3-phase converter and I would like to measure its currents as fast and accurate as pos...
Posted on April 22, 2015 at 12:07I have a signal going into one of the pins on a STM32F303 which is set up in analog mode as an input to an ADC. It is fed by a 2K2 resistor. The power supply on the MCU is 3V. If the signal being fed into the 2K2 goe...
