Generic C library for R3xx/ZFMxx/FPMxx/R551 fingerprint modules

fpm-c's Issues

Delete the fid from fingerprint module.

Which parameters do I have to pass to fpm_delete_model in order to delete the fid from the memory of fingerprint module.

stm32f10x_conf.h: No such file or directory

I am using stm32 nucleo f411RE with this code. after compilation it gives me the error that "stm32f10x_conf.h: No such file or directory". Is there any file that im missing to add ? Or is it about something else.

why usart1 called in enroll_mainloop ?

Hı Brian Firstly,
I read your code so many times,when I started to create my libraries.I assume Usart1 used as Bluetooth module for serial monitor and Usart6 used for Fingerprint module.After these configurations applied I debug my code and started But code stay always in enroll_mainloop because of this line: " while (uart_avail(&uart1) == 0); "

``

void enroll_mainloop(void)

{
  while (1) 
      {
	USART_Puts(USART1,"parmaginizi okutun lutfen\r\n");
	while (uart_avail(&uart1) == 0);

	USART_Puts(USART1,"parmaginizi kaydetmek icin bos sablon araniyor\r\n");
	int16_t fid;
	if (get_free_id(&fid))
		enroll_finger(fid);
	else
		USART_Puts(USART1,"No free slot in flash library!\r\n");
	while (uart_read_byte(&uart1) != -1);  // clear buffer
   }
  }

//UART_MAX_RX_SIZE =256 uart1->rx_head=0,uart1->rx_tail=0 I received this values

uint16_t uart_avail(uart_t * port)
{

return ((uint16_t)(UART_MAX_RX_SIZE + port->rx_head - port->rx_tail)) % UART_MAX_RX_SIZE;

}
