Crate ectool

Library for accessing System76 ECs First, construct an access method, using an object implementing the Access trait. Next, an Ec object can be contructed, which exposes the command interface.

There are some differences between targets and features that are listed below:

• AccessHid requires the hidapi feature. Only functional on USB ECs.
• AccessLpcDirect requires the redox_hwio feature and a nightly compiler. This method is only recommended for use in firmware with LPC ECs, as mutual exclusion is not guaranteed.
• AccessLpcLinux requires the std feature and linux target_os. Recommended for LPC ECs, as this method can utilize mutual exclusion.
• EcLegacy, Pmc, and SuperIo all require the redox_hwio feature and a nightly compiler. It is only recommended to use these in firmware, as mutual exclusion is not guaranteed.

Macros

Structs

AccessHid	Use USB HID access, only for USB ECs
AccessLpcDirect	Use direct hardware access. Unsafe due to not having mutual exclusion
AccessLpcLinux	Use /dev/port access with file locking
AccessLpcSim
Ec	Run EC commands using a provided access method
EcLegacy	Run some EC commands on previous proprietary firmware
Firmware	Parses firmware information from a firmware ROM
Pmc	Standard ACPI EC interface
SpiRom	SPI ROM transactions
StdTimeout	Timeout implemented using std::time
SuperIo	Super I/O interface provided by LPC ECs

Enums

Error	Errors returned by operations
SpiTarget	Target which will receive SPI commands

Traits

Access	Access method for running an EC command
Spi	SPI bus transactions
Timeout	Timeout for use in blocking operations
