Re: BLE multi-connection procedure

I'm also interested in getting details on this. Something which hasn't been yet answered.

I2C Pins.

According to the datasheets, ESP32 has two i2c interfaces.
And one set of pins corresponding is (21,22).

What's the other pin set that can be used for the second i2c interface? Are they also dedicated or any GPIO pin can be configure as I2C?

Cheers.

Re: Increasing RTOS Tick Rate, >1000Hz

Ah I see. It's quite interesting fact though, to know that possibility exists. Thanks Angus.

Re: Increasing RTOS Tick Rate, >1000Hz

Hi Angus,

Thanks a lot for the detailed explanation. I'm going to try the timer interrupt method and it seems the best way to do it yet.

On a side note, what do you meant by Running RTOS on one core and something else on the other core?

Thanks again.
Cheers.

Re: Increasing RTOS Tick Rate, >1000Hz

Hi kolban, Thanks for the explanation mate. I've to agree with you on what said above, my goals was to poll an mpu6050 at 400hz. I know i always have the options like MPU interrupts and timer interrupts to try out. I just wanted to see the capability to do in this manner given I don't have any other...

Increasing RTOS Tick Rate, >1000Hz

HI all, I need to get a tick rate above 1000Hz to be able to get sub-millisecond delays in vTaskDelay, vTaskDelayUntil API methods. Ideally my goal is to establish 2.5ms delays without using timers. Right now SDK seems to limit it to 1000Hz, even if i change the sdkconfig parameters it defaults to s...
