documentation files in .rst format

in the documentation directory of the esp-idf, most of the files are in some '.rst' format. I can open the files in most any editor/word processor/browser. But he files clearly have block diagrams and other material in some sort of markup format that nothing I've tried, and I've tried several, can d...

Re: ulp code as an esp-idf project component not compiling

I have not experimented with any directory structure other than that explicitly supported by the esp idf, but I have a project using ULP code in which a directory appears in main called ULP. The .S files in that directory both assemble and are linked into the program of which the .cpp file is in mai...

Re: Flash port

Angus,
That fixed it. I must have set that months ago and, never having had cause to change it, forgot about it.
Thanks. Works perfectly now.

Flash port

Someone gave me a LOLIN32 dev board which I want to use for some tests. The problem is that when I plug it into my Win dev box, it comes up on COM5. So I go into "serial flasher config" in "make menuconfig" and I set the Default serial port to COM5. I verfied that sdkconfig knows this. It shows the ...

What actually goes out on an http client post request

I have an application in which I post json data to a web server, and the code works. But in delving into the entrails of what's going on, it seems that esp_http_client_perform() pulls a bunch of stuff from the client structure to assemble the packet that actually goes out. I've had to modify the cli...

Re: Suppress Boot messages

I had the same problem, the need to suppress boot messages to the terminal. I've found the complete solution. It consists of 3 steps. 1. As mentioned in earlier posts (> 2.5 years ago), strap GPIO15 to ground. In "make menuconfig" 2. Bootloader config -> Bootloader log verbosity -> (no output) 3. Co...

Quick question on Newlib

When calling a function such as strncmp() from Newlib, how much of Newlib is linked into an executable? Is just the function and any necessary supporting code pulled in, or is all or a large chunk pulled in also. If much extraneous unused stuff is linked in, I'll write my one functions in that categ...

Re: Question about the WR_REG ULP instruction

Is there any documentation on the ULP assembler other than the instruction set that appears in both "Read The Docs" and the TRF? In particular, I'd like to know what assembler directives the assembler knows about. I was surprised to find that it it took the .macro directive and a few others that I f...

Re: Question about the WR_REG ULP instruction

OK, sorry for the new post for each question. This is an add on. I did what you suggested, changing the order of the calls, and it worked. I then substituted in the instruction I'd first tried, "reg_wr 0x006, 24, 24, 0", at the new location, and it worked too. Thanks. Another question: The code I'm ...

Question about the WR_REG ULP instruction

I would like to be able stop the ULP timer from within a ULP program just before I wake the system so as to prevent the ULP from running until I want to again start the ULP and go into deep sleep again. I asked about this before and you referred me to ulp.c wherein is defined ulp_run(), ulp_load_bin...
