Issue recording at 2kHz on SD card (Cyton v3.0.0, Python) #74

Open NeuralControl opened 7 years ago

NeuralControl commented 7 years ago

Hello, I am trying ask via python to record on sd card at 1kHz, using v3.0.0 I looked around and tried quite a bit but cant get it to work. My code looks like below, does anyone knows what i'm doing wrong by chance? i get createfdContiguous fail without softreset, and if i do a soft reset i get back to 250Hz, Thanks

board.ser.write(b'~6');sleep(1);read() # ask 250Hz board.ser.write(b'v');sleep(1);read() # soft reset board.getSampleRate() # check 250.0 board.ser_write(b'a');sleep(1);read() # record ~14sec sleep(20) board.ser.write(b'~4');sleep(1);read() # ask 1kHz board.ser.write(b'v');sleep(1);read() # soft reset board.getSampleRate() # check 1kHz board.ser_write(b'a');sleep(1);read() # record ~14sec sleep(20)

Can you rephrase?
