PSRAM driver

Post by pythoncoder » Sun Oct 31, 2021 6:01 pm

I have added support for the Adafruit 8MiB PSRAM to my suite of memory device drivers, which may be found here. As per the other drivers it has these characteristics:
  • Multiple devices may share an SPI bus to form a single logical RAM.
  • It is possible to use the RAM as a (huge) bytearray or to implement a littlefs or FAT filesystem on it. This may be mounted and used like flash or SD card devices.
  • If used as an array, supports slice operations.
  • The driver is portable between MicroPython targets.
  • The SPI bus can be shared with other devices.
