fabiovila / Makefile
Last active October 1, 2023 21:28
Makefile that find any *.c *.s and folders with *.h. Target is ARM Devices. For use with VSCode or command line.
#Part two of two files that recursivaly find and compile *.c *.s files
# and automatically adds folders with *.h files to gcc include option.
# Made for STM32F103 ARM devices and for use with VSCode
# with few changes these files will work in any toolchain
include Makefile.inc

fabiovila / fs2hex.cpp
Last active December 12, 2017 16:50
Embeddeds files in a folder -recursively- into C/C++ H files with name and size. The files are stored at array fsFiles with stFile struct type that has .name , .data and size fields. I'm using this in order to serve files from a ARM board running a web server with FreeRTOS , Lwip and Mongoose. #stm32 #embedded #c #filesystem #mongoose
#include <iostream>
#include "boost/filesystem.hpp"
#include <fstream>
#include <map>
#include <cstring>
#include <string>
// Turn all files from a folder into hex char with name and size.

How send large files with Mongoose with low memory? Send in parts.
static void ev_handler(struct mg_connection *nc, int ev, void *p) {
if (ev == MG_EV_ACCEPT){
nc->user_data = Alloc(3 * sizeof(int)); // My malloc implementation
print("ACCEPT\n",7);
}
if (ev == MG_EV_CLOSE){
AFree(nc->user_data); // Free of malloc implementation
print("CLOSE\n",6);
}

fabiovila / send-nextion.c
Created May 30, 2018 00:33
Send and set object values in Nextion LCDs on Arduino or general Serials
// Usage:
// setObj ("OBJECT.PROPS", "VALUE");
// obj - name and propertie of object
// txt - value
// example:
// setObj("t0.txt", "Test");
// Warning: Your IDE (as Arduino) is very likely that be UTF-8 wich causes the LCD don't renders the exact string that you pass to setObj
void setObj( char *obj, char *txt ){
Serial.write(0xFF); Serial.write(0xFF); Serial.write(0xFF); // Usefull when Serial connected to LCD is the same of Debug (my case in NODEMCU)
for (;*obj != 0; obj++) Serial.write(*obj);
