Friends, help me set up a platformio.ini file to use the heltec v4 device.
Microcontroller: ESP32-S3R2
Communications:
Wi-Fi: 802.11 b/g/n, up to 150 Mbps.
Bluetooth: LE, Bluetooth 5, Bluetooth Mesh.
LoRa: SX1262 chip, power up to 27 dBm, sensitivity -137 dBm.
Memory: 512 KB SRAM, 2 MB PSRAM (PSRAM), 16 MB Flash.
There is no ready-made configuration.
(Sorry, I’m from Russia, there may be inaccuracies in the translation).
I used these typical settings
[env:heltec_wifi_lora_32_V3]
platform = espressif32
board = heltec_wifi_lora_32_V3
framework = arduino
board_build.partitions = partitions_custom.csv
board_build.flash_size = 16MB
With these parameters, the device works without errors. I also created my own partition table for 16MB and 128KB NVS. But these settings don’t use these variables. The board v3 parameters are still read (default: this board). And upon verification, it turns out that the flash is 8MB and the NVS size is 20KB. I can’t get the compiler to recognize my settings. I need to use all the flash memory for maximum efficiency. I also need to connect the 2MB RAM correctly.
