I need to do a full USB PD power negotiation. but can't get it working. tried using modified example code at github https://github.com/umbe-s/US The STUSB1602 documentation is not comprehensive enough to figure how it exactly works. Any help would...
Hi friends,I'm going to start a project that the system using a Bluetooth module (like HC-05) will read different power values (RSSI) of another Bluetooth module from different directions, using Mcu like STM32F7xx Nucleo Board and KEIL (forex. watch ...
If I want my app running on iPhones and Android phones to communicate between phones via Bluetooth Mesh, does this library/API/framework enable that?To be clear, I am not looking for a mobile phone to “control�?/communicate with devices like sensors ...
Dear all,Can someone help me on that topic ?Goal : I need to send a large amount of 8 bit via SPI as fast as possible (SPI display).The frame buffer is around 160 000b so size need to be uint32_t. Strategy :Use SPI register to avoid 16bit size HAL li...
Hello, if I understand correctly from the document (https://www.st.com/resource/en/application_note/an5027-interfacing-pdm-digital-microphones-using-stm32-mcus-and-mpus-stmicroelectronics.pdf), the SAI interface can only handle at most 8 PDM digital ...
Hi, We are using SPBTLE-RF BLE module in our design. In Production, We are observing the following issues.Observation-1:After the PCB is assembled.When we do Power Check. On few PCBAs We are observing current value of 70mA to 80mA. If we isolate the ...
How I use the BlueBRG as HCI-UART, on Bluez 5.55 stack as BT LE LR Dongle, command on btmgmt "find -l" thoes return nothing... ?
We are using the RHFACT04 gate. In a fault-mode, where the path between an external driver and this receiver is broken, the input will be pulled down by a 10k resistor. At maximum input capacitance this violates the DSCC of 0 - 8ns/V slew on the inpu...
Dear ST community. I am new to this forum and am not a programmer. Hoping someone maybe able to help with an issue.I have a unique invention that can advance a number of industries which uses MEMs motion sensors and allows a computer to become much m...
Hi All,I'm a newbie at STM32 device. Now, I have STM32L433 and I would like to try CAN loopback mode at my device. Does anyone can help me out? It does not work. Please check the attachment. Thanks.
