Hi all,I'm trying to create a project to read a temperature sound like a DS18B20. The problem is that I need a precise and stable delay time. Using Systick isn't possible because there's a conflict when using BLE. I tried using an MFT, but I can't cr...
On ST87M01 current version 2.7.0 I suspect that everything that goes in module via "AT" interface passes through filter which removes spaces and sets everything lowercase. This is OK for AT commands, but it mingles with user data that is passed, for ...
Hi, I can't read 40bit with my BlueNRG-1 and help wit timer in free-running. My us is ok but when i tried to read, it stop before read all 40 bits. Here i post my driver dht11. In main for test uint8_t h, t; if (DHT11_Read(&h, &t)) { printf("Hum...
Hi all,I was super exited to test the new STUSB4531 IC on the EVAL-SCS006V1.The PPS support of the chip is the main reason to pass over from the STUSB4500. I have done a lot of test with 100W PPS enabled USB-C supply but without luck. i did not manag...
Hi,I have a working 3-phase STPM33/34 energy meter. Voltage is correct. The current is wrong by a fixed factor of approximately 60.Setup:CT: 80A primary / 5A secondaryBurden resistor: 6.8 ΩGain: x2Mode: UART with auto-latchExpected reading: 0.6A → Ac...
Hello, I have designed a custom PCB for sensor acquisition and I am using an STM32U575 as main processor and then a BlueNRG-M2SA module configured as a coprocessor with the DTM_SPI.hex image. They are both connected through SPI but I can't seem to ge...
H563ZI Nucleo and Nucleo-67W61. Using the CLI Binary version 1.1.0 I get: #### Welcome to ST67W6X CLI Application ###### build: 20:14:53 Sep 25 2025--------------- Host info ---------------Host FW Version: 1.1.0[ERROR] [575] [spi_xfer_engine] (spi_if...
I am designing a board with the ST87M01. I am using two separate LDOs (TLV757 series) both connected in parallel to a 5V VBUS source.Rail A: 3.3V for GPIO/UART.Rail B: 2.5V for the Modem PMU.Since both LDOs start simultaneously, there may be a slight...
Hi,hope you doing good.We are currently using NUCLEO-L412RB-P along with X-NUCLEO-60K1A1 for testing. We are attempting to perform USB tunneling with the following sequence: 1.NUCLEO-L412RB-P is connected to X-NUCLEO-60K1A12. X-NUCLEO-60L1A1 part and...
We have several custom boards with ST67W61 modules. If we flash the device with t02, per instructions on wiki, we are able to successfully communicate with these devices and also re-flash them if need be. So far so good.However if the device is flas...
