Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I am reading the "dm00294449-bluenrg-1-bluenrg-2-ble-stack-v2-x-programming-guidelines-stmicroelectronics.pdf " and created the coding accordingly. The recommended coding void bluenrg_process(void){ tBleStatus ret; //uint8_t local_name[] = {AD_TYPE_...
Hi,I am testing the STEVAL-BFA001V2B development kit to evaluate the use of the IOLink protocol. Using the native project provided in the software package for the STide development environment, the device connects to the master and works correctly. T...
Hi, Im interfacing STW81200 with SPI without no success. I do have the following questions:What the SPI mode? Its not clear on the datasheet. It seems that CPOL = 1, and CPHA = 1.In either way, I have tested the communication with several modes and n...
ST BLE Sensor 5.2.4 is closed once "Blue Voice Full Duplex" is selected. Below error message shown.
The IO-Link Master (multiport-hub) M12 port on the STEVAL-IDP004V2, has threads on the outside and is female on the inside.The M12 on the STEVAL-IDP003V1 has threads on the outside, and pins on the inside. Both are 4 or 5 pin compatible. I need cabl...
All,I'm working on the basics of getting the SPI communication set up for the L9780 IC and am running into some issues, so I'd appreciate some feedback or a double-check. It appears so far that I'm able to send a command via the control word and succ...
Hi,I'm beginner in USB-C and USB_PD some things are not clear for me.We developing a device which is a USB SLAVE Device - not HOST (Virtual comport device - datalogging to a notebook)This device has a large battery, so we want to charge the notebook ...
我尝试使用 STM32L4R9 与 AD7768 通信，使用 8 个通道。我想知道的是：是否可以使用 DCMI 建立 AD7768 与微控制器之间的通信（微控制器支持，但我不确定 AD7768 是否支持 DCMI。）如果 AD7768 也支持，我想知道 PCB 应该如何正确布线。Translation to English I am trying to communicate with the AD7768 using the STM32L4R9, using 8 channels. What ...
Background:Our project utilized ST's IMU sensor LIS3DH, and according to business requirements, we used click interrupt and initial interrupt respectivelyThe sampling frequency is 10HzWe set the duration of the Initial interrupt to 120 to generate an...
Posted on May 14, 2014 at 19:25Hi, My Interesting is the next, how can I use Spirit1 Auto retransmission and auto ack abilities in half duplex communication. My coordinator is supplied with main power, but nodes are powered by alkaline batteries. Th...
