HeliumOS

Simple command line interface for create and manage tasks based on STM32

🚀 Features

• Automatic baud rate support
• Automatic generation of help functions
• Support for errors and function arguments
• Protection against incorrect commands

🖥️ Configuration

1. Adds USB support in the MCU and sets it as a virtual port in middleware section.
2. Changing buffer size APP_RX_DATA_SIZE to 40 characters in usbd_cdc.if.h file.
3. Add code in CDC_Control_FS function in CDC_SET_CONTROL_LINE_STATE switch case in usbd_cdc.if.c file.

/*SYSTEM INTERRUPT TO CHECK IF THE COM PORT HAS BEEN OPENED*/
    	USBD_SetupReqTypedef * req = (USBD_SetupReqTypedef *)pbuf;
    	if(req->wValue &0x0001 != 0)
    		hostComOpen = 1;
    		else
    		hostComOpen = 0;

4. Add code in CDC_Receive_FS function after USBD_CDC_ReceivePacket function and before return (USBD_OK) in usbd_cdc.if.c file.

  /*SYSTEM INTERRUPT TO RECEIVED DATA*/
  extern uint8_t receivedData[40];
  extern uint8_t receivedDataFlag;
  memset(receivedData, 0, sizeof(receivedData));
  strlcpy((char*) receivedData, (char*) Buf, (*Len) + 1);
  receivedDataFlag = 1;

5. In USER CODE BEGIN Includes in file main.c add #include "heliumOS.h"
6. In USER CODE BEGIN 2 in file main.c add helium_init();"
7. In main loop in file main.c add helium_mainLoop();"
8. At this point you can start creating a new tasks!

🗺️ Guide for adding a new task

1. Change number of tasks by editing the taskNumbers variable in heliumOS.h
2. In the section for new tasks in the heliumOS.h file we add a new function in the format: void helium_task_X(char * args); where X is the task number.
3. In helium_init function in the heliumOS.c file just write data in structure just as in example task.
4. In helium_parseCommand function in the heliumOS.c file add a new task to switch block.
