The SD card module provides the micro memory card interface and it is connected to ESP32 via SPI port. This experiment, creates a “sample text file” inside the SD card, and then written with the running text. ESP32 opens the “sample text file” for reading and dump the text on debu...
sd = machine.SDCard(slot=2) os.mount(sd, "/sd") # mount os.listdir('/sd') # list directory contents os.umount('/sd') # eject RMT The RMT is ESP32-specific and allows generation of accurate digital pulses with 12.5ns resolution. Seeesp32.RMTfor details. Usage is: ...
