Or more importantly, how do you write a PutPixel function?

hi guys note, SPI Master driver with example since few days now in the ESP-IDF displays some fancy graphics on the ILI9341-based 320x240 LCD on an ESP-WROVER_KIT board best wishes rudi ;-) Hi Rudi, Is there a full library version of this using the ESP-IDF (latest SPI) for ILI9341-based 320x240 LCD ...

Thank you so much Neil. Will try it out and come back

So what I am trying to do is TCP Socket server on a device (ESP32) emitting string data (not json now but maybe later) coming from different peripherals (3 for now). Client is more like a wireless display in this scenario: 1. TCP Socket client on another ESP32 device 2. String of information comes t...

I have used queues to pass strings around in some of my projects. What I do is allocate storage for the string (so that it is not on stack) and then add a pointer to the string into the queue. The reader of the queue then sees a new entry which is a pointer to the string, works with the string and ...

A queue actually is made for items with a defined length; if you throw in strings it'll waste a bunch of memory. Maybe you want to look at the ringbuffer implementation (in components/freertos/ringbuf.c and components/freertos/include/freertos/ringbuf.h) instead? Unfortunately, I also do not have a...

I am looking for an example where a char string is passed between tasks (producer/consumer).
Most of the examples I have seen are using numbers like int.

Thanks in advance

Thank you for the response. Will run through some tutorials soon.

I changed the loop as well... since it makes better sense

I just changed it to this using bytesSent and seems to be working... does it look right? I am new to socket programming :) static void sendData(int sock) { int bytesSent=0;    while(1)    {       if (bytesSent < 0) // check disconnect       {          // client disconnected???          ESP_LOGI(TAG,...

Thank you for the response. My sendData function is like this. What do you suggest to check the socket disconnect? static void sendData(int sock) { while(1) { if (sock < 0) // how to check disconnect??? { // client disconnected??? ESP_LOGI(TAG, "[%d]",(int)sock); break; } char *line = readLine(MY_UA...
