Or how about the FRC1? Can the ULP access this?

We are not trying to save power. we just need a clean read of the pins without fear of being preempted by another process. The ULP can do this but without a timer, it is inconsistent. Would it be possible to have a hardware timer output to a pin that the ULP can see? It would then use that as a refe...

It is the rev 1 version of the DevkitC.

Here is what I found from trial & error: - RTC bits 0-9 require the following initialization to be used as inputs from the ULP: rtc_gpio_init (IO#) - I don't see why this is required because the function description says "This function must be called when initializing a pad for an analog function." ...

This is running on the devkitc (wroom daughterboard). The files can be put in place of the files in the "ulp-example" project found online and built/flashed. (The files have the same names as the files they replace.) #include "soc/rtc_cntl_reg.h" #include "soc/rtc_io_reg.h" #include "soc/soc_ulp.h" ...

I understand BT classic is slated for SDK 3.1. Any news on when we can expect this? Would be nice to have an example that is as easy as wiring up a HC-05 (a very common BT daughter board) for applications running on the APP processor.

I know the ULP can wake after so many cycles of the 150khz RTC after a "halt". Once the ULP is running, is it able to access the timer peripherals? We have a ULP program that reads an optical encoder into RAM so the main processors can then scoop it up. But the loop rate of the ULP is unstable. With...

See ULP code below: This runs at about 80-120khz. Ideally, it loop consistently and at least 100khz. Ideas? This is part of a project to read rotary encoders. Thank you for your time. #include "soc/rtc_cntl_reg.h" #include "soc/rtc_io_reg.h" #include "soc/soc_ulp.h" // Define constants .set rows, 20...

See code below. I am sending small packets as quick as possible. I know I can increase the overall data rate by sending larger packets. But is there a way to increase the packet (loop?) rate itself? I already maxed the CPU at 240mhz. tried different RTOS tick rates, etc. Don't remember if I tried ch...

I am wondering the same question. Like I am sure many people new to the ESP, you are here for a project or business need and you want to quickly evaluate if the ESP is the part you want or if you should just keep looking. So you run some of the examples and get different results. Iperf makes it look...
