ATTiny45_Player_SD

Instructions for use of the SD card player using the ATTiny45 RISC microprocessor
:
If the SD card has a wav directory, it will automatically play the files in the directory
. If the SD card does not have a wav directory, it will play the wav files in the root directory of the card.
 
This project has been verified and everything (including firmware) has been open sourced.
 
I support non-profit secondary creation.
 
The Q399921242 program firmware is in the attachment. For burning, use the USB ISP
 
ASP and ATTiny45 link as follows
to connect the chip to the programmer
attinyx5 series The connection between the microcontroller and the USB ASP programmer can be referred to the figure above. It should be noted that the MOSI and MISO pins should be cross-connected. This is the same as when we use Arduino's serial communication, the RX and TX of the control end and the TX of the controlled end. The principle of cross connection is the same as that of RX. Please refer to
 
the pin diagram of ATtiny45/85 microcontroller
 
for reference.
