Good Morning everyone, lets brainstorm.Against my will, i might be designing star topology CANBUS networks.So i need to figure out how to set in firmware the EOL resistor value. My ideas:Rele activated EOLs, expensive and bulky.Programmable resistor ...
Starting from ST EVMboard "B-L072Z-LRWAN1" I made my PCB with the murata module "CMWX1ZZABZ-091" (LoRa/Sigfox). To put my board to work, I have done the "id request procedure" with success, the same as I did for EVMboard.Now I am plannig to go in pre...
How can I do such kind of interfacing. Also note , this TETRA device needs a specific USB driver to install and run while connecting with the PC windows. Does the development board can support only those usb devices which don't need a driver run?
Do you have a typical schematic or an application note that deals with such a setup, to have direct hardware control of the TX- and RX-mode, and also to access the TX and RX data in a very direct way?In our application the TX/RX time and RX/TX time i...
Hello. I have STEVAL-IDB008V2 and I have 1 service with 5 characteristics for BLE. I use SensorDemo program coming with STSW-BLUENRG1-DK for tests. Problem is that I can not add more services and characteristics because Out of Memory error is receive...
Is there any silicon level change in S2LP devices with device versions C1 and 91 since we observed there is difference in current consumption in standby mode. 91 is draws 29µA and C1 is drawing < 1µAWhat is the difference between device versions C1 a...
Hi, I am interested to work on Energy Meter Project by using STEVAL-IPP002V1 Board. but i don't understand how to implement DLMS/COSEM Stack over there.So Please suggest me the implementation steps for this as soon as possible.thank you
Hello,I've started to suspect that something is not quite right with the BlueNRG-1 ST-Link Utility. I have a ST-Link V3 connected to STEVAL-IDB008V1M. I can flash and debug the module from Keil uVision5, but when I try to flash the module from BlueNR...
Hope all of you are well:Using the BlueNRG-232: I'm trying to figure out how to read 2 of the analog inputs. Ideally, I'd like to read both analog inputs and the battery voltage. It appears the only way to do this is set the ADC up to read only on...
i need of stm documentations about distance range.
