How is the ULP coprocessor going to be programmed?

[urbanze]

Anyone can write an example of "blink" with ulp? Just toggle on/off a pin...

I tried with "libraries" WRITE_RTC_REG(RTC_IO_TOUCH_PAD0_REG,RTC_IO_TOUCH_PAD0_HOLD_S,1,0) and simillars but doesnt worked. I had sucess with use ulp + delay, for, whiles, vars, but gpio not.

I see before, and dont understand write(reg)

You can explain better how it work?

There are several instances of using "WRITE_RTC_REG" in https://github.com/krzychb/ulp-loop/blo ... op_blink.S.
Which one would you like to be clarified?

Or you do not understand description in manual - http://esp-idf.readthedocs.io/en/latest ... ers-access

Which sentence in readthedocs are you referring to (regarding 'the readthedocs html docu specify that a signed byte offset can be used to read data')?

Quoute: https://esp-idf.readthedocs.io/en/lates ... the-memory

=============================================================
LD – Load data from the memory

Syntax
LD Rdst, Rsrc, offset
Operands
Rdst – Register R[0..3], destination

Rsrc – Register R[0..3], holds address of destination, in 32-bit words

Offset – 10-bit signed value, offset in BYTES
=============================================================

That looks correct, please see the following section for an explanation:

Very nice example, thanks.

hoho, sucess! Thanks for this links.
