I work with STPM34 and STPM33. I want to make a relay protection terminal with it. You have to take readings very quickly. Every 20 milliseconds.How i think it working:1) RMS current and voltage registers count RMS value 200 milliseconds and then the...
Hey,I am using an LSM6DSM with a 32bit MCU,I am using the generic C code provided by STM,I was able to configure it and get inital readings but after some time,it has stopped sending reading ,I am checking the "status_reg.xlda" value to check for new...
I have an application where I wake-up the BLUENRG-2 source from IO11 is low. but its not work. as a debug I config UART On Tx IO4 & Rx IO 5. for wake up and sleep I print sleep and wakeup. its continues print wake and sleep. when I set IO11 to GND, o...
I was not able to find the answer to this in the QA/Knowledge Base. I understand ST documentation says not to mess with the STM32-F103xx as it comes pre-programmed from the factory. However I have a board whose serial communications between the hos...
I purchased a STEVAL-STWINKT1B development board and inside it has the STR485 chip for RS485 communication.I tried using the cube mx and configured it appropriately (see image 1 attached), enabled uart2, RS485 flowcontrol and then checked that the pi...
Hi,I work on a project, the objective is to communicate nRF52840 with ( STEVAL-STMODLTE , puce with modem BG96 steval-stmodlte ) .the problem is that I don't receive the correct data from the modem .I attached a screenshot of the data received . and...
We have an application where the STUSB4500 is used in conjunction with and STM32L4 family MCU, handling USB2.0 data. So the STUSB provides power (USBPD) and the DP DM lines are routed to the MCU. There is an issue specifically when using a macOS lapt...
Hi! I'm working with spirit1 module. I'm monitoring internal registers reading them one time per second. After reset mc_state registers C0 and C1 contains values 0x02 and 0x07, what means READY state. I'm trying to put it now in RX mode with command ...
Hello,Is they have any PCB antenna design (.dxf file or other) which i can use with BlueNRG-2N ?Tahnk you,Sincerely.
I want to connect 7 LED's on one output in series, using a current of 20 mA. Each LED can have a forward voltage of 3V, which means 7 x 3 = 21 V. I want to use a power supply of 24V.I read in the specifications that the max Vo (Output Voltage) is rat...
