Interfacing LMP91000 with arduino #2

Closed Ashwini-Shankar closed 3 years ago

Ashwini-Shankar commented 3 years ago

Can we completely interface LMP91000 with arduino? If yes, how do we do it?

hoilett commented 3 years ago

Yes. You can find the connections here: https://github.com/LinnesLab/LMP91000/blob/master/README.md and in the LMP91000's datasheet: https://www.ti.com/lit/ds/symlink/lmp91000.pdf

Can we interface LMP91000EVM with Arduino? (without communication board) How will the connections be in this case?

Thank you.

Respected sir, interfaced Arduino mega with LMP91000, but how to see the output data using LMP91000 AFE software. how to use ANALOG Front end software to interface with LMP91000 and see output data for chronoamperometry and other cyclic voltammetry. https://user-images.githubusercontent.com/76556368/103086388-86caff80-460a-11eb-83c5-8f152e972c23.jpg. https://user-images.githubusercontent.com/76556368/103087747-8896c200-460e-11eb-94b5-0f39e590cb4a.jpg. https://user-images.githubusercontent.com/76556368/103087775-9ba99200-460e-11eb-8557-5102d377ec8a.jpg https://user-images.githubusercontent.com/76556368/103087789-a8c68100-460e-11eb-8433-65b4e15924f0.jpg.

@Ashwini-Shankar If you're talking about this board (https://www.ti.com/tool/LMP91000EVM), yes you can interface it with the Arduino. You'll need the same connections (SDA, SCL, 3V3, DGND, etc) described in the README (https://github.com/LinnesLab/LMP91000/blob/master/README.md). Just look for where those connections are labeled on the LMP91000EVM board.

@ramakrishna722 I don't think you can use the Arduino Mega with the LMP91000 AFE software. You probably need the SPIO4 board to use the software.

ramakrishna722 commented 3 years ago

respected sir, so how to use same codes u mentioned in ur profile. how to see the output when we interface arduino with LMP91000 and see the output for ELECTROCEMICAL IMPEDANCE SPECTROSCOPY.

ramakrishna722 commented 3 years ago

how to make electrochemical impedance spectroscopy by using LMP91000 potentiostat by interfacing with the arduino and where to see output

hoilett commented 3 years ago

@ramakrishna722 I don't have any example code electrochemical impedance spectroscopy (EIS). I think I could get something working up to 1-2 kHz, but that's about it.

ramakrishna722 commented 3 years ago

I think I could get something working up to 1-2 kHz..pls can u give up to this ...i have to implement ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY...

hoilett commented 3 years ago

@ramakrishna722 I don't have time to attempt this in the foreseeable future, so I don't know when EIS will be an available feature. Feel free to give it a try. You can find some attempts at doing EIS with my KickStat device:

repo location here: https://github.com/LinnesLab/KickStat-Paper-Firmware firmware here (line 1144): https://github.com/LinnesLab/KickStat-Paper-Firmware/blob/master/KickStat/Firmware/MiniStatButtonCell/MiniStatButtonCell.ino

TQ SO MUCH SIR

hoilett commented 3 years ago

@ramakrishna722 no problem. Thanks for asking.
