EDA Sensor Electrode Gel

Dear Team, I have read in the document "Publication recommendation for the EDA" ( http://download.xuebalib.com/xuebalib.com.7601.pdf ) that, For EDA recording, electrode gel or paste must contain a chloride salt, with NaCl being most often used. Concentrations in the range of 0.050–0.075 m...

Re: Is it possible to achieve higher baud rates via BT module?

Thanks for the datasheet.

It is indeed possible to set any baud rate by entering into the AT command mode.

Regards,

Is it possible to achieve higher baud rates via BT module?

Dear Team,

I am using the Freestyle BT Kit. And I am using STM32 to configure USART.

Is it possible to set higher baud rates than the specified 115200 baud?

Thanks,
Velu

Re: EMG SENSOR ACQUISITION

Dear Team, Thanks for the response. Yes, the STM is connected via USB and I've read somewhere in the forum, the laptop is preferred to be in the Autonomous mode (Not in the charging mode). Today, I've managed to see some good results (I believe). I am sharing them with you for your reference here: h...

EMG SENSOR ACQUISITION

Hello Team, I have been trying to do EMG sensor acquisition with the STM32F4 kit. I've tested the ADC functionality of my code using a potentiometer and it does work well. However, when I am connecting the sensors analog output to the GPIO pin of the STM kit, I just see the random ADC values. I've u...
