Hi everybody
I'm new to power electronics and this cause i have a question.
What are differences between Mosfet technologies such as Optimos , Planar , Trenchfet and Hexfet...
Hi everyone:-D
I am interfacing OV2640 camera module to the stm32f429 arm microcontroller.
I find the library for this camera and use it for my application but in that library maximum resolution supported is 320*240. Setup configuration for camera is shown below;
/* QVGA 320x240 */
const...
Ok,
I am using stm32f429 discovery board for capturing image from camera and displaying that on the tft LCD.
for capture i am using dma to storing images on the external RAM and as well for displaying image on the LCD i am using the another stream of dma, but in both i don't use double buffering...
Hi everyone
in stm32f429 micro-controller, DMA module has a Double Buffer mode. I want to know usage of this mode. Where applicable?
Any help is appreciated.:grin:
Re: standard format for transfering image from microcontroller to computer via USB
i found this online program for my demand.
https://davidwalsh.name/demo/camera.php
ok, but in C programming when i decided to define pointer to the function like below:
int cmp(const char *, const char*));
pointer to this function is like below:
#include "string.h"
.
.
.
.
.
int (*p)(const char *, const char*);
p=strcmp;
but in this code there is no red pointer and the code...
hi everybody
i am new in c programming, and i have a question about pointer of functions.
consider the code shown below:
uint8_t *(*GetConfigDescriptor)( uint8_t speed , uint16_t *length);
in the code there is two pointer for function in color of red and blue.
i know the task of the blue...
Re: standard format for transfering image from microcontroller to computer via USB
thanks for your response,
ok, i write the microcontroller program relevant to usb video class,
but in the computer i don't know which program can receive the stream of video transmitted from microcontroller to...
standard format for transfering image from microcontroller to computer via USB
hi everyone
i am working on stm32f4 discovery board and i need to building webcam with that and interfacing it to a computer via USB. at this point i am confused which standard format for transferring image and...
I am really admire when I see the excellent operation of thermostats such as Honeywell vs my designed thermostat.
that thermostat really good operation in the same conditions that i tested my designed thermostat, but i misknow what is reason of this.
i am making two structure for the sensor.
1. the first structure, sensor is placed on the heatsink and heatsink is placed at the room.
2. the second structure, sensor is placed behind the frame. the frame was rimosed for flowing temperature of room in to frame.
schematic is shown below:
program is right because in the ac duct, sensor is work well due to to high density of air flow.
but i need to sensing temperature in the corner of room that doesn't sufficient air flow.
the example behavior of sensor:
when cooling system is off, the temperature was...
hi everyone,
i am intend to build a thermometer for house to controlling speed of cooling system.
The sensor that i used for this porpose is LM35 but it is not able to measuring room temperature accuratly, i don't know reason of this. when the cooling system is worked and we are chilled, the...
hi guys,
I am creating the stepper motor driver with A4989 stepper driver ic. every thing is OK but the motor is generating too acoustic noise. the circuit is used for converter is shown below:
other configuration for a4989 is:
PFD2 = 1, PFD1 = 0
MS2 = 0, MS1 = 0
SR=1
In your opinion, what's...
