Hello again to all...need some opinions from you all...I purchased a cpld XC9572XL-10VQG64I to replace the damage one. Does it need programming or just plug & play? really appreciate any inputs....thanks
I have a PCB design with an onboard uC (ESP32-WROOM-32D) and voltage regulator (AMS1117-3.3). The PCB doesn't have USB comms or power, so I want to have a separate "bootstrapping" board which has those things and connects to the uC via a 4-pin header. Should I add a diode to protect the voltage regulator on the board with the uC when power is com
Hello, I'm new to the forum but hopefully you guys will give me some great advice. I have been programming microcontrollers for the past five years, only as a hobby but I do plan to move to this as my career, I am currently a machinist but I don't quite have the means for university yet. I'm 27, so should still be capable of learning :razz:

Hello, Is possible to add CCFL light or LED backlight to a 6 digit/7 segment lcd display which has no backligt from the beginning? I have seen some article about doing that many years ago (could not find now...) by removing the reflective shield layer from the backside , not sure if I should seprate that shield from a possible layer (polirizati
Hi, everyone! I'm an electronic enthusiast from China. I'd like to ask you a question. Recently, I made an RF power amplifier with 2sc1971, and connected the transmitting antenna to adjust the standing wave to a minimum of 1.05. Instead, the transmitting power is not as large as when the standing wave is greater than 1.05. Why? Thank you!
Hi All, I am using PIC18F46k80 in Hardware and for software MIKroc PRO and for programming using MikroC PRO library. My CAN initialize code is; Can_Send_Flags = _CAN_TX_PRIORITY_0 & _CAN_TX_XTD_FRAME & _CAN_TX_NO_RTR_FRAME; Can_Init_Flags = _CAN_CONFIG_SAMPLE_THRICE & // form value to be used
Hi. I want to drive NOKIA 5800 lcd with microcontroller but my problem is pinout details of lcd connector. I mean, I have no documents or datasheet of it to undrestand about timing and protocol of lcd pins. I also downloaded the relevant files like "Nokia service manual"(lcd pinout attached), but i cant undrestand CDP0 (...)
Could someone please take a moment to explain what the technical blocker are, that currently prevent CPU's, DRAM, VNAND and all the appropriate controllers all being integrated together on a single SoC die? I understand that economically it may not be an optimal solution. But cost-no-object, and assuming all the appropriate licenses are obtaine
Hello, I have a BIN file called "some_file.bin" I want to copy the contents of this file to another file named : "some_file_2.bin" However, while copying I want to skip every 4th byte. For example : Contents of "some_file.bin" : 0xA5 0x3 0x11 0x34 0x33 0x12 0x37 0xDE[/CO
What are sequence to initialize HD44780 display device ? . are given in page 42 to initialize in 4 bit mode but the table it seems confusing me 1. Display clear 2. Function set: 3. Display on/off control: 4.
Hello! I tried to write my own code for 2 push buttons to rotary encoder (UP/DOWN Quadrature generator) I have flashed it (ofcourse with changed ports) on PIC16F648 and it works perfect, it also works perfect in Proteus simulation with PIC12C509 (C509 was the closest i have to F509). The problem comes when i program it on real PIC12F509 - the c
Good evening to all I am not speaking about code I want to understand communication between MCU and lcd how does microcontroller send data to lcd so I made one flow chart that explain my understanding I have attached PDF file and I am looking advice with my flow chart

Is there a way I can use the programmer on the ATMEGA328P-XMINI to program an external ATMEGA328P on another PCB?
Hi i have a 2inch spi tft lcd with st7735 driver and i run emwin library on it using stm32f103ve. i dont use external ram for emwin and just use micro ram for emwin. i can use all of emwin capability except memory device. i try evrything but memory devices wont work. is that because of i dont use external ram or memory devices wont work on spi lcd
Hi, What technical informations did you give that we can use to find a solution? When a monitor flickers, then usually it's because * monitor type: input signal range * graphics card output signal: resolution, frame rate, (Maybe even a mature "interlaced" signal is output by the graphics card) * noise introduced into the monitor cable (signals):
I have separate codes. 1) for displaying data on 16*2 lcd which is shifting at 0.5 seconds 2) another code for playing songs on DFplayer (2 minutes song whic plays when I press a button) I want to play the song and the text on the lcd to be shifting at the same time. How do I do that. bec the code waits till the song is being played by the
