โ
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
Three bytes of register configuration
0b11010110
0b11010100
0b11100000
Data transfer - "s", ends - "p"
Serial with baud rate - 115200.
