WebAug 13, 2024 · I’ve hardwired the MCP4921 DACs to Arduinos MOSI (51), SCK (52) and (SPI)SS (53) and I’ve tried several Arduino MCP4921 libraries but the result is the same. No output on DACS output pin. myDac.analogWrite (2048); delay (1000); myDac.analogWrite (0); delay (1000); but the output is in 0 voltages. I dont have a scope … WebFeb 1, 2024 · I have been trying to get help or example sketches on how to use I2S to output audio using in-built DAC pins 25 and 26. I can get dacWrite to work on inbuilt DAC but cannot get I2S itself configured to output to the DAC pins analog 25 and 26. dacWrite is OK for low frequency audio but I gather that using I2S functions would be faster. any … dia gurney plumber
