I2C bus master driver

There was a generic interface that supported lots of different devices, i.e. Acc/gyro etc

The whole point of this is to determine, which type of light ALS sensor is fitted.

Maybe i'm trying to be too cute with this.

chBSemWaitTimeout

can one use chBSemWaitTimeout in interrupt context ?

ive got a shared data structure

A thread fills it with data.

RTC callback uses the data to update clk .


so need to protect the shared data structure, chBSemWaitTimeout fails in RTC callback

Re: Cortex-M33 and Arm TrustZone ?

So between the two OS's running you have some kind of API ?

From the reading ive done its sounds like there will be a significant amount of complexity added
