What is the use of TEST pin on BlueNRG-1? STEVAL-IDB007 has a 100K pull-down connected to it, with a jumper that allows a connection to VDD. BlueNRG-MS has it connected directly to GND.Datasheet states that it should be connected to GND, so I expect ...
Dear members, reading iO-Link transceiver datasheets like for the L6362A i wonder why the Q/C pin and the DI/DO pin are capable of driving loads, i.e. like inductive loads? As far as i understand these pins always are connected to the master, never ...
I have two KSZ8851SNL connected to an STM32H7 board.In a certain operating mode, I would like to make a 'transparent' connection (on link level) between the two interfaces, so the board with the two interfaces acts like a simple hub.So if I receive a...
Hello everyone. I'm working with the S2LP transceiver and the 802.15.4g packet format. I'm using the SDK coming with the x-cube-subg1 (https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/s...
Hello There,This a question for those who know Firmware and Hardware well.Currently I am working IAR 7.80.2 1 months trial version.I need some help.Currently I am trying to download firmare of WIFI module through a USB serial COM port.I have SDK firm...
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...
