Hi,Kindly advice how to communicate with an external device has CP210x with stm32f4 via USB FS mode. Is there any driver? In my project i want to read an external sensor data via USB. That sensor transmitting the data via CP210x chip . Please advice....
Hi everyone, i am trying to establish a USB communication between my nucleo-L073RZ and my PC. I have stripped a USB cable to connect it to the usb pins of the board (PA12 & PA11) and it worked well but i wanted to buy a cable (not homemade) to do it....
I am finding that the BlueNRG-M2SA module's power on reset is very flaky when used with a coin cell battery. More often than not the board does not boot after the battery is inserted. You then have to wait for close to 2 minutes before trying again.T...

HiI would tike to use the ST25DV04K NFC tag in a Lorawan end node based on the on the CMWX1ZZABZ-091 module.Can you please provide more info on the ANT7-T-ST25DV04K reference design? I was not able to find the pcb documentation.I addition to that, ...
hello, We are using ST3232 as new project design and I measured waveform as below, does this waveform is normal or not？we use 3.3V power supply with 100nF ceramic capacitors. do you have a solutionthank you in advance
I have just started getting this and wanted to understand why and how to resolve. I have done a Mass Erase using the Flasher utility but that doesnt make any difference
Using the SDK's BLE_Privacy project as a base, I changed the Master & Slave programs to function with the static random address stored in NVM by commenting out the aci_hal_write_config_data function that was setting a public address and changing the ...
Good day.I'm pretty new to BLE and I've a pretty hard time getting the hang of it.I'm using the Sensor Demo example, delivered with the X-Nucleo-BNRG2A1.I've now a custom board with the BlueNRG-M2 as a coprocessor with a STM32F030C8T6 (SPI).The elect...
I'm having trouble with i2c communication. In my i2c bus, i have 4 boards (STM32L4 Sensortiles) and sometimes one of them blocks the bus and the others stop communicating consequently. When I reset that one that blocks the bus, all boards starting wo...
