CCS/CC2640R2F: Initializing a slow part.

Jason Gardner

Part Number: CC2640R2F

Tool/software: Code Composer Studio

Hello,

During boot up, I have an I2C part that is particularly slow. It takes 150mS for the part to self configure/boot up and each write to a configuration register can take up to 100mS to execute. The reason is that when configuration is updated the part writes to the part's internal FLASH. Which is slow.

Is there a preferred way of waiting for a slow part like this? I saw in some of the examples that a sleep function exists, but I also saw in some of the help cases that sleep might not be the best way.

Is there another function that would work better in this circumstance?

Hi Jason,

How about allowing the BLE application to start and execute your needed code from there in your own state machine. Finalize by using a callback that triggers device to start advertise or whatever it's purpose is.

Thanks for the quick answer.

I thought about what you were saying but decided to go with a simple function that uses system ticks.

Thanks for the help.
