I went to my familys house and they had an issue with their speakers. It turns out the audio cable broke, though I looked at the TV and this is a 2009 TV, and I'm guessing Made in China vga or 2.5mm wires.
Hello all! First of all, I want to apologize for my poor English. I'm from Russia. I have STM32F103C8 boad and I am trying to compile a project from this article (source code . zip) in the Atollic TrueSTUDIO for STM32 9.2.0 environment,

Hello. This is my first custom ATMEGA 2560 board. I need some advice whether this board work properly or not. avr Newbie needs your help! This board contains these functions. 1. Compatible with Arduino Mega 2560 Bootloader & Arduino IDE. 2. Uploads compiled file using Arduino IDE through USB TYPE C port. 3. Able to

does anyone know what is the frequency of operation in variable gain amplifier under nb-iot applications. The vga is after mixer and no study is conducted about this topic.
Hello, i've recently found that Attiny85 and Atmega32u4 come with differential ADC capabilities. I was messing with load cells (strain gauge wheatstone bridges) used as weight/force sensors. Usualy people are wiring these with HX711 ICs, which is 24bit differential ADC made just for these purposes. I wonder if i can instead connect the load cel
The two pics show 2 different implementations. The d_f_mem is a multiplexed input from <1> keyboard or char_ram(pic1) or <2> data_mem or eeprom. but here is not keyboard connect only cpu vga data mem, eeprom, so where i have to connect the keyboard to wich pins? I did not completely understand your question. Do you want to hav
hi can somebody explain me, how does work this char_row = row_addr; font_row = row_addr; //char row 8x8 char_col = col_addr; font_col = col_addr; // char col 8x8 this 8X8 font but the address for row and adress for col , what does do this bit 4 in row and
Dear all This is my 1st thread in this useful forum,welcome all To all who like to use the powerful and flexible Microsoft visual code to develop their avr applications or don't know how to use it, I have uploaded a video demonstrate this in details, the video explain how to use ms visual code and also how to use it to burn produced Hex file
Don't use Variable Gain Amplifier, instead use a Programmable Attenuator.( There are tons of such attenuators in the market..)Because vga will disturb the signal with its own nonlinearity. Also, use a Directional Coupler OR a RF Power Detector IC ( look at Analog Devices or similar mfg.) to measure accurately the RF Power then you can control RF Po
Hello all, I have made little hardware. It has two relays. One is for controlling a cooler fan and another one is to control power to the electrical equipment like soldering iron and all. Power will be supplied by grid tied invert-er. I am reading ADC of solar panels. Once ADC of panel is above one threshold, relay controlling power to electrica
Hello I'm a winner I want to do the same thing as doing the reverse engineering This bad thing works with rs485 bootloader What do you propose? By identifying these data, I would like to write a program with these data
Hi Can you please tell me what is the difference between PGA and vga? and does the microcontroller sense the input or the output to adjust the gain? Thank you
HI I have a microcontroller avr ATMEGA644 that I want to get the hex code but the microcontroller is locked. Somebody has some training or tips on how to get the Hex code locked microcontroller? THANK
Hello, I have been working on a project where I need to convert vga video signal into HDMI, is there any chips for this? i searched a lot and found a couple of chinese manufacturers and was hoping to find something different from that. I also would like to know if there is any way to extract audio from HDMI signal and put it on a separate aud
Hi All, I was wondering as to how to design CMOS switches for FFE for SERDES in 112GBPS. It is a quarter rate architecture. I am using PRBS data pattern but the switch is showing more output at sampling node (Node after sampling switch. where the sampling capacitor is put) then at the output of Source follower resistor (75 ohm)
Hi I want to write a windows application that can create hex file for microcontrollers. I had seen single exe file that creates hex file for avr micros, but there is no compilers called. Can any body give me an idea how to it is done. Any inputs, examples, links will be helpfull. I can write programmes for microcontrollers in C Na
Hi, I am making a vga based project with Xilinx FPGAs for 640X480 pixel resolution. Can anyone suggest any crystal oscillator value which I can divide to get exactly the pixel rate of 25.175 MHz (or as nearby as possible). Thanks, Arvind Gupta.
Hi I want to buy a programmer for avr microcontrollers (dip packages). I want it ro be relatively cheap (hobbyist) and have a ZIF-40 socket so that I can remove the MCUs from the circuits and program them standalone on the ZIF. Any ideas of which ones to buy would be helpful.
