Hi Pluto,
I have come across a forum where you have been discussing the conversion of hex data from an SD card to decimal format.
Did you managed to successfully achieve this? I am looking to do the same.
Thanks for your help.

plutoYes Sam,
I was able to achieve the same, I do not have the firmware with me, give me a time for a day or two to send the logic to you. -
ShyamalHey Pluto,
Can I have the logic for converting hex data into decimal format? Also, did you use python for conversion? -
SamvbHi Pluto,
Happy new year!
Just following this up, have you managed to put together the logic?
Does the converted decimal file read like a CSV file streamed via the dongle?
Thanks for your help

plutoHi Sam,
Appologies for the delayed response,
The hex to decimal conversion of data I could figure out in from a forum discussion, could implement the logic.
For each hex values do the below operation:
If MSB > 7, means input number is negative, perform 2s complement, multiply by scale factor, then multiply by -1 at the end
else, just multiply by the scale factor,
at the end, convert everything to int. -

Veo que estás en España, yo también. Tienes Wallapop, porque allí puedes buscar por emotiv y creo que soy el único que tiene uno a la venta. Sino pásame una dirección de email donde te pueda enviar los docs

Hi retiutut,
I have come across a forum where you have been discussing the conversion of hex data from an SD card to decimal format.
Is this possible using the following code:

Thanks for your help.
