Part Number: FDC2114EVM Other Parts Discussed in Thread: FDC2114 , FDC2112 I'd like to know how to optimize communication throughput for the FDC2114. The data sheet states 400kHz/400bps I2C clock frequency, as well as 13.3ksps maximum output rate for the…
Hi David,
Thanks for the detailed explanation on the progress using the FDC1004 for your measurements ? I am just curious to understand why you are replacing the magnetic solution to a capacitive based solution ?
In regards to your questions to if FDC1004…
Part Number: FDC2214EVM Other Parts Discussed in Thread: FDC2214 , FDC2212 , FDC2114 , FDC2112 , Hello,
I'm currently working on a project in which I have to measure changes in capacitance that is connected to the channel 3 of the EVM.
The problem is,…
Part Number: FDC2114 Other Parts Discussed in Thread: FDC2214 , FDC2212 , FDC2112 Hello,
Regarding to schematics on FDC2114, my customer is asking a question.
(Question)
They will refer FDC2214/2114 EVM schematics for design.
Each(FDC2214 and 2114) schematics…
Part Number: FDC1004 Other Parts Discussed in Thread: FDC2112 , FDC2214 Hi,all
1. Is there any software reference code for FDC1004 and FDC2112 ? Please send them to me.
2. I want to use FDC1004 or FDC2112 to detect the moisture of skin, like below block…
Part Number: FDC2114EVM Other Parts Discussed in Thread: FDC2112 , , FDC2114 Hi,
I would like to use a capacitance sensor for detection of a person present at a distance of 10 to 50mm.
FDC2112/14 seemed to be a good solutoin, so I ordered the Evaluation…
Luke,
Capacitive sensing could work, although this looks like a small amount of liquid to detect. The two relevant devices are the FDC1004 and the FDC2112/4.
The FDC1004 uses a more traditional capacitive sensing approach. It has an out of phase shield…
Joey,
For the FDC2112, only one register needs to be read. The device supports repeated start, so the math becomes:
-Three frames per read command (9 bits each, serial bus address byte from master + data MSP from slave + data LSB from slave)
- Extra…
Hi Jed,
The resonant sensing capacitive sensing devices (FDC2112/FDC2214/FDC2212/FDC2214) can be constructed with a lower tempco, although in general it is recommended to use a multi-sensor design with a reference channel.
Regards,
