Re: store data in Flash (not Spiff)

Fast enough for my Project.. As Final Step i Change the App Partition to 3.5MB and add my binary Data as constant array. Maybe ist the same Speed.. the Display Limit is 40mhz. @Bodmer i use TFT_espi.. its a good Library ;) But for ILI9488 i made many optimizations, Transparency Functions, Speedup et...

Re: store data in Flash (not Spiff)

Done! I create my own Custom Partition and Uploaded my Pictures.bin to this Partition. After Mapping the Partition i can join the data on Data Pointer Very Fast. const esp_partition_t* part; spi_flash_mmap_handle_t handle; void* data; esp_err_t err; void setup(){ part= esp_partition_find_first(ESP_P...

Re: Storing Jquery as a C-string

I think there is a problem with the escape symbols, maybe there is a function for it.

Try before Insert in Code:

Re: store data in Flash (not Spiff)

Ok, i have start a new try.. i created a new partition in arduino Default.csv and uploaded my Pictures.bin with Downloader tool to the startaddress of the Partition. Now I try to read the image data: const esp_partition_t* partition = esp_partition_find_first(ESP_PARTITION_TYPE_DATA,ESP_PARTITION_SU...

Re: store data in Flash (not Spiff)

It is possible to mmap to Mybin.bin in Spiff if i know the startbyte? Here is my try and Error(actest is my array): #include "FS.h" #include <TFT_eSPI.h> #include <SPI.h> #include "test.h" TFT_eSPI tft = TFT_eSPI(); #define TRUE 1 #define FALSE 0 #define SPI2_NSS_PIN 28 static const int spiClk = 400...

store data in Flash (not Spiff)

Hi, At the moment I compile a 1.3MB array in my code, I want to put this byte array now in Flash to save compile time. Whats the best way to do this? Spiff is too slow. My first try was write directly to flash partition.. but it did not work. Could be the fastest way to work on mapping?Or store data...
