Zilogic’s ZDev library provides a set of easy to use API interfaces
for rapid embedded firmware development. ZDev provides APIs for
accessing hardware controllers and devices. It is based on C language
and targeted at tiny micro-controllers like 8051 and ARM. ZDev
currently supports the following boards:
-
ZKit-51-RD2 (only 6x clock mode)
-
ZKit-51-V664
-
ZKit-51
-
ZKit-ARM-1343
Following is the short list of ZDev’s features.
-
Provides APIs for interfaces - I²C, SPI, DAC, ADC, PWM and Serial
-
Provides APIs for devices - buttons, keypads, LCD, 7-segment displays etc.
-
Makes the application portable.
-
Comes with extensive documentation.
-
Distributed under a permissive open source license.
-
Can be easily extended to other boards and controllers.
-
Well tested and suites well for quick product development.
