I have a esp that received and logs twai messages. To send the messages, I use a PCAN dongle. I use an infinite loop to send messages to the esp forever. The esp receives the messages fine when I start sending the messages AFTER the esp has booted up. But the esp doesn't receive anything when I ...

Why is this useful: https://github.com/khoih-prog/AsyncWebServer_WT32_ETH01
Despite the normal ESP32Async/ESPAsyncWebServer working just fine with Ethernet on the WT32 ETH01?

What if the message is so large that it doesnt fit in the RAM of the ESP?

Hi,

I would like to know if there is a method like sendContent, but for ESPAsyncWebServer instead of the normal (sync) Webserver? I have a project and would like to convert it to use ESPAsyncWebServer.h instead of the normal Webserver.h library, but unfortunately there are many lines webserver ...

The problem is that I don’t know the size of the data in advance. Most of the time, the partition isn’t even close to being full, but occasionally it’s nearly full.

Maybe I could read the partition header to determine how much space the files are using? But even if that’s possible, is there any ...

The partition I use for my LittleFS is called spiffs:


Name , Type , Subtype, Offset , Size , Flags
nvs , 0x1 , 0x2 , 0x9000 , 0x5000 ,
otadata , 0x1 , 0x0 , 0xe000 , 0x2000 ,
app0 , 0x0 , 0x10 , 0x10000 , 0x140000 ,
app1 , 0x0 , 0x11 , 0x150000 , 0x140000 ,
spiffs , 0x1 , 0x82 , 0x290000 ...

Hi,

I want to write a function that gets executed even during a flash write operation. I have already tried this:
I have delared two tasks (on different cores):


void setup() {
Serial.begin(9600);
delay(2000);
// Create task1 on Core 0
xTaskCreatePinnedToCore(task1, "Task1", 2048, NULL, 1 ...

Hi,

I need to write a value (0 or 1) to flash storage in order to save it permanently. I need to do this in my custom bootloader (the bootloader_main.c code).

The way I do it now is I have a seperate partition to which i write the value with the function

void write_boot_index(esp_partition_pos_t ...

Is it theoretically possible to receive CAN / Twai messages in a custom bootloader in any way?

I have already tried to import the driver component in bootloader_components\main\CMakeLists.txt: set(requires “bootloader” “bootloader_support” “spi_flash” ‘driver’), but the line #include “twai.h” in ...

Yes I am currently trying to make it work.

My platformio.ini file looks like this:
