Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
Currently i am aware of different methods to connect them. But i am most interested in LTDC. I have tried using old protocols like Motorola 6800 Parralel RGB. But Touch screens of bigger size and bigger resolution available on Alibaba for example do...
In the example code of STSW-STUSB003, we can see that the NVM of stusb4500 is divided into four sectors, each of which has 8 bytes. We want to know the definition of each byte,and we didn't find any information about this.Can we ask for the detailed ...
Hello. I am trying to establish a working wireless communication between two radio units using S2-LP components.Both units are an S2-LP development kit which includes a nucleo-L053R8board with a mounted STEVAL-F433V2 board.The code is the example pro...
Hi folks,we just completed a custom RF interface board for our product.It's a simple SPI-to-Antenna board with TCXO and BALF, in the 862-868 MHz band.The TCXO is powered by an LDO at 1.8 Volt. This allows us to use a battery.The S2-LP is powered exte...
Hello everyone,I'm trying to communicate with a SPSGRF-868 from a Nordic 52840 Development Kit, but a very strange behaviour affects my SPI communication. When I connect ONLY pins CSN, MISO, MOSI, CLK and SDN of the SPSGRF to the Nordic, leaving VDD ...
Hello, We are planning to use an Analog Front END IC for power line communication (with proprietry protocol)* 400 - 600 bps data rate* DC power line with voltages up to 80V* BFSK communication with sinus mark and space frequencies around 2.5 Khz & 6 ...
The B-L475E-IOT01A contains the spsgrf-915 module. I want to use this without an extension board to run FP-NET-6LPWIFI1. Is it possible? It is necessary to refer to it if possible.
Hello,Is s2-lp RF module supports mesh? If yes, where can'i found mesh stack and how it can be used?Is below application note describe how can'i configure s2-lp module to work on mesh network? https://my.st.com/resource/en/design_tip/dm00567382.pdf...
Hi, I have recently buy an X-NUCLEO-IDB05A1 in combination with a NUCLEO-L053R8. The documentation furnished with those board says that there is working code examples in form of a .bin file that you just need to drag and drop in the NODE_L053R8 "driv...
I managed to pair bluenrg-ms with my smartphone. (pairing complete arrives with status = 0x00 and everything is okey) but if i want to disconnect from it i can't get any events. I can press "disconnect from paired device" on my phone but nothing hap...
