SPI Master DMA transmission requierement: one byte at a time with gaps
Hi all, working on a new project I encountered a problem where I'm not sure whether it can be solved without additional hardware or not. Using an ESP32 with the arduino framework, I realized an UDP multicast receiver. Its job is to receive a multicast transport stream at a rate of approx. 5 Mbit whi...

ESP32 I2S with DMA buffer issue: ways to detect buffer over/underrun
Hi, a recent project involves audio transmission with ESP32's using external I2S codecs and ESPnow, all written using the Arduino environment in PlatformIO. Current setup: Audio transmitter Wolfson WM8960 in i2s slave mode, 48kHz sample rate, 16 bit stereo -> ESP32 running an instance of the OPUS co...
