DFPlayer Mini - control via Software Serial & ATTTiny85
Account cancelled 2020-12-15 23:57:46 2652 Views4 Replies I've got the DFPlayer Mini (MP3 player) working easily with an Arduino Uno. Controlled via RX & TX using Software Serial library.
I'm trying to move the simple code (basically the standard example code from DFRobots website) to work with an ATTiny85 using pins 3 & 4 or 0 & 1 for Software Serial. However, with the same code and changing the pins to correspond to the ATTiny pins instead of Arduino ones the code compiles uploads to ATTiny ok and then when I connect the DFPlayer either a) nothing happens, or b) buzzing noise comes out of the speaker. Light on the DFPlayer doesn't turn on, no signs of life from it.
I've checked the wiring (multiple times now) does anyone have any ideas as to what I might be missing or doing wrong?

2022-01-01 03:42:49 Recently, I was looking for a design site editor to do artwork for one of my client’s projects. I prefer to visit to hire top developers to get more helpful tips. After some research and some head-scratching, I decided to give DFPerter Mini a try. Perler Mini was designed to work as a website designer. This is a feature I’m sure many website designers will appreciate. faway57320

The hard serial port refers to the USB converted serial port connected between the main control board and the PC. You may use the hard serial port (pin0 and pin1), which is occupied Can’t upload code and read data in case of 347945801
347945801 2021-01-07 15:24:18 Hello,
I have also problem with the function from the library <SoftwareSerial> - I work with the platform ESP8266. But if I would start to play a soundfile - the hole board reboot again. So thats looks for me that RX/TX not really works fine - and the errorlogs show me stack-problems in the memory.
Have anyone experiance with DFPlayer AND ESP8266?
Kind regards

1. Whether the serial port is connected reversely
2. Is the power supply voltage consistent with the wiki?
If you still have problems, you can send us the code to see 347945801
