It is not medical device!!! And can not be used for any medical purposes!!!

#### How it Works  

[Gerbers files](https://github.com/Ildaron/ironbci/tree/master/gerber_files) for PCB boards.  

[Hex file](https://github.com/Ildaron/ironbci/blob/master/ironbci.hex) can be uploaded to STM32F407VE by ST-LINK V2 RST  

 Connection:  

                        - RST      

                        - TCK    

                        - gnd   

                        - TMS

####  2.  General pin information about ADS1299 signals

![alt tag](https://github.com/Ildaron/ironbci/blob/master/Supplementary%20files/stm1.bmp "stm32")​  

SPI2 for communicate with ADS1299    

UAART4 for send data by HC-12  

2.1.DRDY output -  high when conversion starts    

2.2  Two ways to read data:      

      - RDATA - continuous read command;      

      - SDATA - on request.  

2.3. The amount of input data - 24 * 8 = 192 bits + 24 status bits, a total - 216 bits  

#### 3. Configuration of control registers  

Three bytes of register configuration  

0b11010110    

0b11010100

0b11100000

#### 4. Description of code ADS_1299.c  

Data transfer - "s", ends - "p"  

Serial with baud rate - 115200.
