Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
We are running up to 10 temperature sensors which are connected to PC with RS-485 via daisy chain topology. These sensors are placed across the line of sight.Now I am planning to replace RS-485 connection with wireless one while increasing the operat...
Hi,I have the following issue with the cubeMX code generator (v. 5.1.0) with X-CUBE-BLE1 (v. 4.3.0) middleware:Using the Nucleoboard (STM32F401RE) with the X-Nucleo-IDB05A1 , I can easily generate a working nucleo BLE application code. In the CubeMx...
Hi AllIm relatively new to smart cards. Im wondering what is the purpose of using a Smart card interface IC such as the st8024 other than voltage adjustments? Would it not be easier to interface direct if the the intended smart card is a class B? 3V?
I am adding the SPIRIT1 to legacy products that already have a specified MCU. I have the purchased the full STEVAL-IKR002V3 Eval Kit and two additional daughter boards. My MCU is able to read/write to the SPIRIT1 registers, but I cannot figure out ...
I'm trying to understand how I can use a USB Type-C connector together with the STM32MP1 USB OTG peripheral.So obviously I want to use the port in dual role configuration. I want to use the STUSB1600 for that because it takes care of the power source...
Hi,In the STW81200 it is written that the second VCO output can be set to work in-phase or in quadrature to the primary one. In the control registers I can not find a field that is responsible for that option. How should I configure the IC to have se...
I want to rebuild the DTM application to run with a 16 MHz crystal. The DTM project used to be included in the 3.0 DK but it is not in the 3.1 DK. How do I get the project code?
Hello,I am looking to prototype a project. I will need I2C, SPI and UART. I2C for some ST sensors/gas gauge, SPI for sd card and UART for RS485. Is it possible to use SPBTLE-1S, to run both host applications and bluetooth. Thanks for your help
I'm trying to get the discovery board to play a wav file that I've converted to an array of 16b hex values. So far, I have only been able to output an obnoxious noise. I have tried keeping the registered in the CS43L22 all at default.I have tried con...
Dear I want to update the NVM memory on the STUSB4500. May I know the procedure of this, I download the STUSB003 SW lib. it not showing how to write NVM. My guessupdate the register call function void nvm_flash(uint8_t Port)reset Am I right?? also wh...
