Re: Modify data of particular location of flash memory using spiffs.?
I'm not sure if I understand what is the problem. Look at: https://www.tutorialspoint.com/c_standard_library/c_function_fopen.htm "w" mode creates an empty file for writing. If a file with the same name already exists, its content is erased and the file is considered as a new empty file. You can al...

Re: Modify data of particular location of flash memory using spiffs.?
Hi Loboris, We have tested SPIFFS code which is provided in your TFT Library Repository and found one issue. The issue is like we have added some files externally using mkspiffs binary. After that we have opened one file among them in "w" mode only at that time it seems like another same name file h...

Re: Dual core
thanks! if i not use this functions, the code is usually run in core 0? core 1? or in two in same time? any datasheet for this informations? Hi, If you have looked into make menuconfig configurations for your application then there is one options defined into configuration like "[*] Run FreeRTOS on...
Re: Dual core
As per my understanding, By default if you will directly use xTaskCreate API then it will create task for CPU1 as CPU0 is dedicated for WiFi and Bluetooth by default. No it will create task with no affinity meaning it will run on either core, whichever is available. Ok. But WiFi and Bluetooth Core ...
Re: Dual core
So, In short, xTaskCreatePinnedToCore is useful function for you with last argument as to create task for CPU0 or CPU1 based on your task, it's handler, size and it's priority. As per my understanding, By default if you will directly use xTaskCreate API then it will create task for CPU1 as CPU0 is d...

Re: Need sample code for ILI9488 LCD on SPI Interface
@Ritesh Yes, I'm planning to include PNG support. At the moment I'm looking for the best way to implement transparency. As I'm not using the frame buffer ( it will be included later for ESP32 with 4MB of PSRAM ) the data has to be read from display RAM, combined with image data and written back to ...
