EDIT: the following text was a reply for an answer which has been deleted. The user was registered after I opened my topic, and the answer was very ChatGPT-like (it cited the api reference in a slightly modified way) Can you show me an example how to set up detecting a mismatch? The api reference is...

I have a 125 kbit/sec multi-master bus. It takes 8 microseconds to transfer 1 bit. The initial state of the bus is high. In order to transmit a message we need to listen on the bus and if there were no low state on the bus for 16*8 microseconds then we can start transmitting. This might be solved by...

So apparently uploading these files solved the problem:

bootloader.bin @ 0x1000
boot_app0.bin @ 0xe000
partitions2.bin @ 0x8000

After that it is possible to upload just the firmware. Not sure why did it work in the first place though...

I have a small project written in platformio with the Arduino framework. I have exported the binary and try to upload it with the ESP flash downloader. The first upload succeeded (to a brand new devmodule), but for the second time (to the same module) failes with the following error: is stub and sen...

Yes, I converted the 16-bit returned values to signed integers based on the level property in rmt_item32_t. But that doesn't explain the "weirdness". Which was the fact that with one clk_div setting it was working, but with another one it didn't. A you can see I had negative values both in the worki...

Hi, I am fiddling with a legacy automotive bus called VAN bus with an ESP32. I have successfully created a library using the RMT to read it, however I also would like to implement writing purely from software. To be able to do that bus arbitration logic must be implemented. For this I need to listen...

CAN is a bit of a... thing. I won't say we have a CAN controller in our chip (because of ...reasons), but I can say that the ESP32-S2 has a peripheral we call the 'TWAI (Two Wire Automotive Interface) controller'; which happens to be fully compatible with the peripheral you used to use for that on ...

Maybe a second CAN controller, support for MIPI DSI displays, and please keep the RMT peripheral, I just love it, it is very useful.

Hi, I am trying to create an universal remote using the RMT peripheral based on this code: https://github.com/kimeckert/ESP32-RMT-Rx-raw/blob/master/main/rmt_rx_raw.c . It seems like it is working, however there is one thing that I can't quite get which is the clk_div parameter when initializing the...

I took a quick look on that protocol, and it seems that it wouldn't be so complicated to write an RMT receiver library for it. Basically the rmt_van_rx_parse_byte method and the crc calculation method should be implemented, and the rest would be almost the same.
