I2C bit banging component

Kewal — Mon, 25 Jan 2016 19:04:59 GMT

There is a GenericSWI2C component available for bit banging but it is not compatible with KSDK 1.2.0 and KDS 3.0.

So is there any such component available for use with processor expert on KDS 3.0.

Hi Kewal,

you could create a project for Processor Expert without the SDK, then add the GenericSWI2C component and copy over the sources.

In the .c file there are the following macros

#define SCL_SetDir(dir) SCL1_SetDir(dir)

#define SCL_ClrVal() SCL1_ClrVal()

#define SCL_GetVal() SCL1_GetVal()

#define SDA_SetDir(dir) SDA1_SetDir(dir)

#define SDA_ClrVal() SDA1_ClrVal()

#define SDA_GetVal() SDA1_GetVal()

you would need to call the SDK functions.

I hope this helps,

Erich

Yeah, actually I tried before posting this question. I got an error with below description

Error during adding referenced component/template "Unsupported/Wait-UNSUPPORTED".

Component is either missing or corrupted.

It was just a project with processor expert and KSDK option as none. Also tried with codewarrior and found same issue.

Do i need to add any other component?
