Hi All,

I'm confused. I've developed a system (using Micropython) to write an output stream to a pin using the RMT function. It works perfectly when the ESP32 is plugged into my computer, but doesn't when it's plugged into a battery. I've confirmed the battery is fully charged and is delivering ...

Hi All,
I got a couple of modules from a local supplier. I have a programming board for normal esp32 modules (single antenna) which works fine, but when I try to put the DA module in it the "wings" containing the antennas foul the on the pins on the programming module. My understanding is that the ...

Hi All,
In my continuing attempts to use the RMT peripheral I have now struck another problem. It seems the source array (src) passed to the function must be of type uint8_t, otherwise an error "incompatible pointer type" is raised. Since the duration of each pulse (high and low) can be up to 32767 ...

Hi All,
There don't seem to be too many of us playing with the "remote control" (RMT) peripheral, but this is probably the best place to get help.
I have found that when my program executes either a rmt_write_items or rmt_write_sample command, the program executes the command once and returns, but ...

In further investigation I have learned that the problem has not been fixed as advertised, however there is a workaround. It is simply that the call to rmt_driver_install must be done before the call to rmt_config. If they are done in this order the problem does not occur.

Well, I have learned that this is a known bug https://github.com/espressif/esp-idf/issues/4664 , and it has now been fixed. However I use VS Code with PlatformIO plugin, and it seems the fix has not been migrated to PlatformIO yet, so I can't confirm the fix. I will update this post when I can ...

Hi All,
Apologies if this post is in the wrong place, I wasn't sure where to put it.
I am beginning to explore using the RMT functionality to generate a PPM stream to use in a model radio control transmitter. I used the morse code example from github as the basis of my code. I am using VSCode with ...
