    LCD and DFplayer working simultaneously

    thanks a lot for the help. I found out that dfplayer works on serial port so one just have to give commands to play an audio and then the main code runs as usual. I need to write the logic to see if the song has finished playing before playing another.

    [SOLVED] Rtc ds3231 with arduino

    thank you Klaus. I have checked the data sheet and nowhere it mentions the use of EEPROM, it just need two lines for I2C. Also adafruit board doesn't use the EEPROM. Thanks for guidance. Now I am thinking why I asked a a question before giving a basic try to its datasheet. I'll write the...

    [SOLVED] Rtc ds3231 with arduino

    I purchased a DS3231 board and its working fine with arduino. This ds3231 board has ds3231 IC and another IC which I dont know what its use was but I searched on internet that is a 32KB EEPROM Recently I searched an adafruit breakout board for DS3231 and it doesn't use that so called EEPROM and...

    undefined reference to posix_memalign in Arm

    I am running a code in Eclipse tool and using cygwin compiler and my code is running without any problem. But when I am running the same code in SDK (vivado) which has arm processor, I am getting the error "undefined reference to posix_memalign". Even when I have included the library stdlib.h...

    Good quality sound using Microcontroller

    I have found a mp3 player. It's called DFplayer, Its communicates with arduino using serial port and plays the audios from the SD card. It is good and cheap. Now I am trying to make schematic of that pcb. thanks a lot guys. :-)

    Good quality sound using Microcontroller

    I am making a home speaker solution. Like when door opens.. it says "door is open". if door is closed it says .. "door is closed".. similarly like.. "Refrigerator is open".... "Geyser is on" .. "Television is on" ... these things I'd like to record and play on different cases. For my other...

    Good quality sound using Microcontroller

    Thank you for the answer and the details. I am thinking that I'll record audio with 16 bits depth at 44.1KHz or 22KHz(thank you @Klaus for asking these things) and do some experiments with adafruit(thank you @bradtherad for telling about adafruit) for sound quality and store in SD card. as the...

    Good quality sound using Microcontroller

    I am a hobbyist. Doing some experiments with sound quality. I'll pin point my problem and requirements. 1) Problem statement : I want to play audio files ( recorded in human voice, not music files, just some plain human speech files) 2) I have tried : a project with arduino microcontroller...

    [SOLVED] Integer to string convertor for mikroC

    @ milan.rajik Hi. My Integer to string program is working efficiently and LCD out program is working perfectly and independently. When I tries to combine both , then it is not working. While running, in one program, for "inttostr" I used inbuilt function for LCD, in another program, for LCD I...
