Code replacement for irrigation controllers

摘要

Some embodiments provide irrigation controllers comprising: a housing; a control unit including a first microcontroller configured to execute irrigation programs and a first set of code; and a removable plug-in device that removably mates with a portion of the irrigation controller and communicationally couples to the first microcontroller, wherein the plug-in device comprises a memory storing a second set of code to replace at least a portion of the first set of code, wherein the plug-in device is configured to re-flash at least a portion of the first set of code allowing a copy of the second set of code to overwrite at least the portion of the first set of code; wherein the first set of code comprises a bootloader that writes the copy of the second set of code over the first set of code with the exception of the bootloader that is not written over.

主权项

1. An irrigation controller comprising:
a housing; a control panel removably coupled within the housing, the control panel including a first microcontroller configured to execute stored irrigation programs and a first set of code of the control panel; and a removable plug-in device that removably mates with a portion of the control panel such that the removable plug-in device is communicationally coupled to the first microcontroller, wherein the removable plug-in device comprises a memory storing a second set of code to replace at least a portion of the first set of code of the control panel, wherein a copy of the second set of code is transferred to the control panel to overwrite at least the portion of the first set of code of the control panel to reflash the control panel.
