Digi International embedded it into some of their XBee wireless radios (802.15.4-based and Cellular models) to allow customers to run an on-device application without compromising any certifications for the radio portion of the firmware. Easier than needing to design hardware with an additional host processor and work out the serial communications between that host and the radio module. While MicroPython was designed to be "bare iron", it wasn't overly difficult to port it to run as a separate task inside the XBee firmware, and connect it up with internals for I/O and file system access. These are ARM Cortex products with firmware sizes in the area of 500KB to 700KB. |
