Hello, I am new to the arduino nano rp 2040 connect. I am building a lightsaber using the 2040 for a personal project (i know about the proffie and CFX I just wanted to challenge myself a bit). I am just trying basic features right now like making sure the IMU works along with the neopixels and sound. Everything works except for the sound. All i want to do is play a wav file from my SD card for now (it is formatted FAT32) but it seems like an impossible task. Most poplar libraries like TMRpcm dont work. I belive it is because It uses DAC which the 2040 does not have. Ive also learned that other boards like the Arduino UNO (which TMRpcm works on) use avr architecture as opposed to Mbed. I am trying to use PWM but am having no luck either. I am able to run a program and read the SD card and have a file name provided so I know its just a matter of converting the information to data the 2040 can read and output. I have formatted the wav file to be (16000Hz, mono, 8bit reso, and U8 PCM). I would appreciate any help! If I have gotten anything wrong please feel free to correct me and add to the conversation as I am new to this particular board. Thank you in advance!
Hey did you get anywhere with this. I am having similar issue? Thinking about buying DAC and doing the I2S connection.
