Hi, I'm building a system where a STM32 MCU needs to be connected to 5 sensors in SPI.The sensors are 5 chip MAX31856 or similar.My doubt is, can I connect 5 sensors to a single SPI line of the MCU? Are there any limits on how many sensors can be con...
Hi, I connect X-NUCLEO-CCA02M1 to my NUCLEO-F401RE. I am using SPI1 for the communication between devices. For what I have understood the function below convert N bit (for me N = 8) in a integer. Since i want to stream via UART those bit how can i pr...
Hi,I'm working on a design with a STPM33. The application only needs to measure current on a single phase but, as STPM33 seems cheaper than STPM32, this was the chosen IC. Could I remove C27 and C28 if the second channel is not used? If yes, could I...
I initialize the sensor like this:uint8_t rst; dev_ctx.write_reg = platform_write; dev_ctx.read_reg = platform_read; dev_ctx.handle = &SENSOR_BUS; static uint8_t whoamI; /* Wait sensor boot time */ platform_delay(1000); /* Check device ID */ lsm6dsr_...
Hello, would anybody know, how much time it takes from start of an acceleration til the value is sent on the CAN interface?
What is the tolerance/accuracy on the sample rate for the LPS28DFW. I do not see this information in the datasheet.
I tried to integrate an example of fft on my existing code and I have a problem "undefined reference to `arm_cfft_radix4_f32'" knowing that I just put the file arm_math.h and after I also tried to put the library DSP and lib arm_cortexM4lf_math.lib a...
Hello,In our application we've found quite big differences in ODR between different samples of the ISM330DHCX and also for different modes:For example if setting the ODR to 416 Hz we measure > 440 Hz. Furthermore when only ACC is active the ODR is 44...
