Hi, We are using ST3485EIDT and ST3485EBDR RS485 IC in our Gateway device to collect the data from Slave devices. We are reading 30 parameters (1 Packet) from slave Device. Frequency: 1 parameter per sec. Baud Rate 9600 bps. We are noticing some issu...
Hello, i am really new to pcb design, in fact this is the first time i done it. the problem i get is, where to do i connect the BOOT0 pin? i know if you connect it to VDD then it will boot from the system memory. if i connect it to gnd then it will b...
I am programming stm32411CeU Blackpill- i want to make connection between the Stm32 and Pc Via RS485 ..i wrote this simple code like in the photo..but i have problem with the output .. i get this weird characters like in the photo i tried different n...
Hi, I'm new with this development board.My target is to use the S2-LP DK Application to configure the board to send data from a GPIO.Do I have to put my data on GPIO_0 and the clock signal to GPIO_1?Why is the clock signal needed?In this way it is po...
Where can I get the detailed technical manual of STSAFE-VJ100-CCC, such as the definition of chip pins?
Hi,I'm searching for UHF RFID reader IC (860-960 MHz). I found the one and only solution as "ST25RU3993". But it is NRND. So, what can I use for my new design. And is there any cheaper solution? This IC is very costly. If I ignore the cost as of now,...
Hello thereI have a custom board based on STEVAL-IDB011V2 EVM. Is the same schematic but I have a problem with this. Apparently it boots but not run... When I flash "Hello World" example I have some issue that I can't check why.... The expected messa...
Is there BLE_SensorDemo_BlueMSapp STM32CubeIDE project for STEVAL-IDB012V1?
hello. I am testing the X-NUCLEO-S2915A1 board. The board has been confirmed to be manufactured for use in the 915Mhz band.When transmitting frequencies in the 940Mhz to 950Mhz band through the board, inefficient frequencies occur above 1Ghz.You mus...
Hello,We are using S2-LP (the 826-958 MHz version S2-LPQTR) for application which uses 826 MHz as a base frequency."AN5528 Radio communication range estimation in ISM band" gives some results about the S2-LP range at 868 MHz base frequency.Could you ...
