SmartSonic™ MEMS Ultrasonic ToF Sensors

Hi there,

Having wired up a CH-201 evaluation module (EV_MOD_CH201) to a Nordic nRF52840 DK, I'm using the Nordic SDK to scan for TWI (IC2) based devices (it is the most basic nRF52 TWI program - the "hello world" of TWI). This scanning is quite simple and attempts to read 1 byte of data from a TWI slave using addresses 0x01 through to 0x7f.

Hi there,

I've recently acquired two CH-201 sensors and wish to integrate them with Nordic's nRF52 devices. Would it be possible to download the C source code based drivers without having to find a Windows PC? On downloading the hello world zip file, I'm presented with an executable for self-extraction. Even a plain zip file would be great.

Thanks in advance.

Kind regards,
Christopher

Hello,

I have CH201-00ABR ultrasonic sensor, and I don't find any library for that. Maybe somebody can help?

Hi,

i got the DK-CH101. I want to connect the daughterboard with a MCU from ST. But I cant find any documents about the pin configuration and description. Are there any information? Especially the pin assignment of the 4 connectors is important. Or did I miss something? Thanks in advance:)

best regards

Just got the DK-CH101 dev kit and had some issues getting it to work with SonicLink. So i reflashed it with the SmartSonic_HelloChirp_v1_11_0 firmware with Atmel Studio without any issues. But when reading from the dev kit through RealTerm, i don't get any sensor readings, see attachment.
I'm reading this through the EDBG USB port at baud 1000000. the FTDI USB does not output anything.

I recently purchased a few CH-201 sensors in hopes of getting it to work with a prototype I am developing. My prototype currently uses an arduino to power it. My question is if there is any way I can the arduino and CH-201 chip to communicate.

Thanks!

I can't download "Hello Chirp Example for SmartSonic 1.11". Clicking the download link at https://invensense.tdk.com/developers/software-downloads/ returns a text file (download_not_available.txt).

When would the download be available?

Could a link to an earlier version be accessible?

Hi,

I am trying to determine the suitability of the CH201 for roughly detecting the walking speed of people walking towards the sensor in a straight line. Does anyone know whether this application is likely to be possible? Would the 45 degree horn be required to achieve something like this?

Thanks,

Ben

Hi all,

I got an error when using SonicLink to connect to the SmartSonic Board. Please help me to see what the problem is
