Hi,I run the "LwIP_HTTP_Server_Netconn_RTOS" example well on STM32746G-Discovery board. I can see webpage after type "192.168.11.1" in browser.I modified the gpio configuration in "HAL_ETH_MspInit"I modified the HSE_VALUE from 25M to 8M (my board use...
Dear communityWith interest I read the following thread on the topic:https://community.st.com/s/question/0D50X00009XkffySAB/spirit1-missing-irqI probably have a similar issue. My application seems to "lose" RX data sporadically. There may be a relati...
hello,i work with the IDS014A4 SPIRIT1 WMbus board,i like to send a frame with the C1 mode(unidirectionel Sent).my first question is : why the Tx frame preparation is limited with12 bytes ?my programme can not sendall the data only when i replace :S...
I want to use an S2-LP based nucleo shield to communicate in FSK with a 433MHz device.I bought the X-NUCLEO-S2868A1 and then noticed that the shield seems tunes only for 868MHz.I do not seem to find on the ST website a reference for a corresponding b...
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 ...
