Hello everyone,I'm actually trying to make a datalogger for a xnucleo gnss1a1.The expansion board is connected with a stm32f446re Following the manual about the connection between the two boards ( referred to stm32F401RE), I've set all the pinou...
I am trying to receive data from the HX711 amp. This module requires a CLK signal from the mcu (stm32407VG). What is the best solution to send a clock signal to the HX711 module from a GPIO pin ? How to configure this GPIO pin in CubeMx ?
Hi everyone, I have a p-nucleo lorawan 3 kit with a nucleo-l073rz board and a lorawan ns1 lora board. I'm trying to setup the AT master example from I-NUCLEO-LRWAN addon using keil uvision. I uploaded the program and activated the CMD_DEBUG but I do...
Hello,The S2-LP errata sheet dated 11//2016 states that the SDO pin does not tri-state as expected, for silicon with device info 0x0391.Has this been fixed in later silicon revision?Please advise. Thank you.Regards.
Hi,We are currently working on a custom board with the SPBTLE-RF0 used for BLE communication and a uC from the L4 family (STM32L4A6VGT6P). We used the SensorDemoBLE example as a starting point and programmed it to the board through SWD. From adding b...
I am developing a hardware using as a board a Nucleo 144 to which I have to connect via I2C (pins set via stmcubeMX) a Melexis 90640 thermal scanner, I am experiencing problems with communication or rather, I struggle to understand the logic of readi...
I need to use FDCAN to send CAN messages. Since I want to receive each message (without filters) I do this :sFilterConfig.IdType = FDCAN_STANDARD_ID; sFilterConfig.FilterIndex = 0; sFilterConfig.FilterType = FDCAN_FILTER_DUAL; sFilterConfig.FilterCon...
Rather informally, in Fig 1, the datasheet of the SPSGRFC module indicates the the module comes with a 50 MHz crystal. However, the SPIRIT1 datasheet clearly states "The allowed clock signal frequency is either 24, 26, 48, or 52 MHz". So, does it ind...
I have a B-L475E-IOT01A board where I am trying to read the Acceleration sensor values from and send them to the PC. I followed this example: file:///C:/Users/nrahardja/Downloads/en.STM32-Education_step4%20(2).pdf. However, the rate at which the data...
Good morning,I'm the tech lead of an high school lab who manages the interactive displais of 10 clasrooms.In any class there is a notebook connected via USB to an interacive display (Promethean Activeboard Touch 78) and to a video-projector.In order ...
