khoih-prog / Portenta_H7_AsyncWebServer

Asynchronous WebServer Library for STM32H7-based Portenta_H7 using mbed_portenta core. This library, which is relied on Portenta_H7_AsyncTCP, is part of a series of advanced Async libraries, such as AsyncTCP, AsyncUDP, AsyncWebSockets, AsyncHTTPRequest, AsyncHTTPSRequest, etc. Now supporting using CString in optional SDRAM to save heap to send very large data

Example of Destructive C string Send, using global declaration (or commented out malloc in heap) string.

Does not use SDRAM.

Hi @salasidis

You're a step behind, sorry. I already update the examples.

Please check and test

  1. Async_AdvancedWebServer_MemoryIssues_Send_CString where we can use #define to select either SDRAM or not, etc.
  2. Async_AdvancedWebServer_MemoryIssues_SendArduinoString

Terminal Debug

Async_AdvancedWebServer_MemoryIssues_Send_CString ===> Using SDRAM, very small heap (12847)
