SmartSonic™ MEMS Ultrasonic ToF Sensors

Hello Together,

I use the CH201-00ABR sensor to develop a distance sensor with IO-Link communication.
We want to use the distance sensor in the area of level measurement and distance measurement.
To adjust the sensor's field of view, we use Acoustic Interface AH-20166-045045.

To get the measured value I use this function:
uint32_t chbsp_stm32_get_range(void) {
ch_dev_t *dev_ptr = &(chirp_devices[0]);
return ch_get_range(dev_ptr, CH_RANGE_ECHO_ONE_WAY);
}

I'm trying to run the HelloChirp application from a generic SAMG55 Xplained Pro developer kit in order to communicate with a CH-101 sensor connected to the SparkFun breakout board. The HelloChirp application can be compiled and flashed to the board from Atmel studio 7 just fine, but unfortunately I'm having trouble communicating with the sensor itself. No matter which configuration I've tried, the program always fails to find the sensor.

Hello,

I am using CH201 to detect presence in a room. (package-smartsonic-presence-example-v1_8_0.zip)

I’m using "presence_v22.hex" firmware and maximum range set to 4731mm. (DEBUG_LOG: Sensor 0: max_range=4731mm mode=TRIGGERED_TX_RX num_sample=300 )
However, the highest detection range I am getting is 970mm.
But I confiugred for 4731mm range.

I configured the sensor as did in the presence sensor example code. (package-smartsonic-presence-example-v1_8_0.zip)

Hello everyone!

I’m stuying and evaluating the MOD_CH101-03-01- I have an DKCH101 Development Kit.

I download the example SmartSonic_HelloChirp_v1_11_0 from TDK site. I’m using 4 device MOD_CH101-03-01 that are connected to the daughter board of the Development Kit.

I run the application without make modification. I only uncommented two define (READ_AMPLITUDE_DATA and OUTPUT_AMPLITUDE_DATA) inside the file app_config.h in order to allow the application to print the full amplitude data after a measurement cycle.

Hi to all, I'm not able to use the devkit for unknown reason.
I'm using both usb cables, as indicated in the guide, and i can flash the FW on to the device.

does anyone have the same problem or knows how to fix it?

Hi my name is Vincenzo,

nice to stay in this forum!

Hi there,
I'm working on CH201 sensor, the sensor didn't respond for the program address(0x45) mention on the datasheet.
I make check on the I2C bus and as well as in coding also, there is no issue. Both Reset and Program pins are high on trying to communicate.
Can any one know help me out from this issue.

Hello,

Hello,

I want to use CH201 to detect presence in a room.

I'm using gprmt_v7 firmware and maximum range set to 5000mm. However, the highest range I get is 1700mm, even if the target is way farther.
When target is closer than 1500mm instead, I see reasonable measures.

Any suggestion for the configuration or thresholds to set? Is there any other possible cause for this behavior?

Thanks
