Serial1.setRxBufferSize(1024); Thanks guys, will try that first and see if it helps me ! edit : i was more looking for a method of increasing the TX in one way or another. My ESP32 has no realy needed data coming back from the other device, i would only need a slightly bigger TX buffer, so i don't ...

Hi to everyone! I have a simple question : On a other (dutch) forum, someone told me that HardwareSerial uses a buffer and interrupts to do the communication with other hardware. Is that correct? If a buffer is used, would that then mean that when a different, external interrupt is triggered, the bu...

Hi chegewara, Two loop functions is not an issue, you can create one or two tasks and run your code in that tasks. Now is the question, why do you need two setup functions? Well the issue for me is that i am building a chronometer for dogsports, but since the dogs run against eachother on two separa...

Hi all, maybe a very,very silly question, but anyway here i go ... Does anyone have a idea on using 1x ESP32 but using both cores with 2 separate programs in each one running arduino code so one would need 2 void setup() and 2 void loop() functions... at first there is no need of data to travel betw...

Hi,

How can I use the "ESP_INTR_ALLOC() API to pin a interrupt to a specific core, and can i be sure that the ISR function would be on the same core?

I can nowhere find a example for this question
Grtz,

Please re-read the first error message. It tells you exactly what the error is. Now if you look to see why the compiler wants to convert 'void (*)(void*)' to 'void (*)()', you will notice that attachInterrupt() requires a pointer to a function that returns nothing and takes NO ARGUMENTS. You are su...

Hi WiFive, read the article, seems very interesting. Allocating an external interrupt will always allocate it on the core that does the allocation. https://esp-idf.readthedocs.io/en/latest/api-reference/system/intr_alloc.html Can anyone point me to a example? Just googled for a sort of hands on, but...

Hi, Is it possible to pin a interrupt routine to one of the two cores (or a ISR function pinned to one of the cores)? The goal is to let some logic be done by one core (trapping external interrupts from eg. a pushbutton) and send a timestamp and some other data to the other core where it can be proc...

Hi all, i have some simple questions about ESP32 programming in Arduino : My setup : Windows 7, Arduino IDE with latest ESP32 toolchain installed, NodeMCU-32S board, 80Mhz,921600, COM4 The esp32 has two cores, one can assign a task to either one of the cores. I would like to do some logic on one cor...

Hi,

Great!!
Back to studying now

If i achieve something good, should i post it here? Or start a different thread?
Is there no such thing as a 'absolute beginners forum' where we can post things we try and then get some do and dont's from the pro's?

Anyway thanks a lot for this help
Grtz, Yves
