Other Parts Discussed in Thread: ADS1292R, ADS1292
art Number: ADS1292R
I'm not used to Eng.
I can read test signal well.
*Sampling rate 250Hz
y-axis is mV, x-axis is sample number.
But I can't read correct signal from electrodes that were connected with CH1. and the signal was 3Hz-50mVpp-Sine wave from function generator.
*Sampling rate 500Hz.
y-axis is mV, x-axis is sample number.
It is similar 3Hz(three periodic wave in 500 samples, 1 sec) but with only positive polarity. and also the amplitude is not correct.
So I changed polarity of input cable. then,
...
I want to read whole sine wave. why these error occurs? my schematic is
VREF was well measured at 2.42V
and register set
write_reg(0x01, 0b10000010);
write_reg(0x02, 0b10100000);
write_reg(0x03, 0b00010000);
write_reg(0x04, 0b00000000);
write_reg(0x05, 0b10000000);
write_reg(0x06, 0b00000000);
write_reg(0x07, 0b00000000);
write_reg(0x08, 0b00000000);
write_reg(0x09, 0b00000000);
write_reg(0x0A, 0b00000011);
write_reg(0x0B, 0b00000000);
plz, help me.
