In lib/l/Makefile line 9, "sdcclib" is used to generate the .lib file. However, it's been deprecated and replaced with "sdar -rc".
Line 9 should be:

Hello,

I am using the stm8l151... mcu and I am trying to send different strings via Uart1 to HTerminal. I have three different strings to send. The first two strings are transmitted completely but when the third one is being sent, it is truncated and it starts to send the first and second string again and repeatedly but when I go through the code step by step, it works the right way.

I have attached the output from Hterm (uart_com) for better understanding and also some parts of my code(uart transmit and uart_init)

Just for better understanding of the attached output, the strings(cmd 1, 2 and 3) are at+nrb, at+cfun=1, and at+cops=1,2,"26201"

Please Any suggestion will be greatly appreciated.😊

`void nbiot_buf_transmit(void){
PAL_UART1_RX_DISABLE();
PAL_UART1_TX_ENABLE();

  for(int i=0 ; i < sizeof(cmd1);i++){
 
    
    USART_SendData8(USART1,((uint8_t)cmd1[i]));
   while(!(USART1->SR));
     while(USART_GetFlagStatus(USART1,USART_FLAG_TXE)==RESET);

}

for(int i=0 ; i < sizeof(cmd2);i++){

    USART_SendData8(USART1,((uint8_t)cmd2[i]));
       while(!(USART1->SR));
     while(USART_GetFlagStatus(USART1,USART_FLAG_TXE)==RESET);

}

for(int i=0 ; i < sizeof(cmd3);i++){

    USART_SendData8(USART1,((uint8_t)cmd3[i]));
        while(!(USART1->SR));
     while(USART_GetFlagStatus(USART1,USART_FLAG_TXE)==RESET);

I was looking to fork / improve this code, and extend it for use with other micros in the STM8 family, but this project is currently licensed GPL.

As such. any use of this code in a project will require licensing of any and all other code to be GPL to be compliant. This is fine for hobbyist or personal use, but for actual embedded product development this should not be a forced decision. Also, this is a library, and the GPL is a poor license choice for libraries (unless, of course, the goal is to further push GPL).

The library you wish to emulate, libopencm3, is LGPL. That is also problematic for embedded software as libraries usually aren't linked, though they have shown interest in adding a linking exception.

Is there any reason this project is licensed GPL, and if none in particular, could it be relicensed to something either more liberal (MIT, BSD, etc) or something more embedded-friendly?
