hi
i just made some changes to the BMI mode of xmc 2go kit . As a result i no longer can comminucate with it from dave4. is there a way to factory reset it? or return the xmc 2go kit to default settings.

Hello support,
I tried to replicate the "DEMO_5QR0680AZ_42W1" board with some minor modifications. Attached I send the schematic.
The difference is the feedback loop, where the 5V output is only controlled.
I did a production of 300 boards, and half of the boards, the chip ICE5QR0680AZ is in a state that tries to start, and after a while, sometimes it starts and sometimes it doesn't!
Am I doing something wrong? Do I have a feedback loop, calculated wrong?


Best regards

Hi,

We are designing new hardware for IMX8QM SoC. For that IR3895MTRPBF and IR3827MTRPBF are some ICs that should use for our design.
But seems that they are in End of Life state in the production process. So could you please let me know the substitute part numbers for IR3895MTRPBF and IR3827MTRPBF ?

Thanks

Hello,
I have a DPS310 eval board connected to an ANALOG2 DISCOVERY tool to generate SPI frames.
I've not been able to get correct temperature and pressure data.
I set the correct TMP_EXT bit in TMP_CFG register to 1 as per what is in Coefficient Source register bit 7 and now I have a much better temperature value
at least coresponding to what it should be around 20°C.
But the pressure is still too low.
My registers are set as follow:
0x06 = 0x14 : PM_RATE= 1 or 2 measuremetn/sec and PM_PRC=4 or x16 oversampling rate
0x07 = 0x90 : TMP_EXT=1 and TMP_RATE=1 or 2 measurements/sec and TMP_PRC=0 (no ovesampling)
0x09 = 0x07 : permanent pressure and temperature measurement enabled
I used for pressure the kP=253952 and for temperature kT=524288
atmospheric pressure is supposed to be 1015hPa now and here. I get only 736.85hPa.
I do think that my coefficients are correct and I two's complemented. Same for pressure raw data.

Do you have an idea where the problem lies? I attached my excel sheet that you used to calculate my pressure and temp.

thanks for your help.

Configuring the pins on Microcontrollers can take a lot of time - so my team & I hacked together a small tool of our own for Nordic MCUs
. Initialise your nRF52832 based projects much faster with Vicara’s Code Generator! A simple GUI to configure pins, peripherals and project files without writing a single line of code.
We currently support GPIO, GPIOTE, PWM, UART, SPI & TWIM with Segger Embedded Studio project file generation. More peripherals and boards to be supported soon.
Please do try it out and share your feedback! The website link is: https://vicara.co/nrf52-code-generator Show Less

hi sir,

am currently working on dps310 pressure sensor with I2C protocol,am getting temperature correctly,but am unable to read pressure values correctly am getting pressure data as 12000,
i configured pressure_config register 0x07 with value 0x33,these means i have selected pressure measurement rate and pressure resolution 8 times as per datasheet,

1.what is the raw pressure i will get when i read pressure registers(0x00 to 0x02)

2.what are the registers to be configured to get exact pressure data...??

plz help me to come out of these issue

thanks & regards
