Hello,I am working in a new project (a USBC rechargable battery LORA board with temperature module) with some leds and a button. I attached the schematic here.I only program all my boards with the USART mode.I choose the L4 family because I want to s...
Hello all, I'm learning about Nucleo F746ZGT6 . and also I'm doing some projects related to this board. I want to ask how much digital voltage & Current at the one pin of Nucleo F746zgt6.
Hello everyone,I am working on a signal analyser device, which needs to transmit data serially as fast as possible (idealy 1Mbaud/s).I am doing the following loop to transmit: uint8_t buf_high[1] = {124}; // '|' uint8_t buf_low[1] = {48}; // '0' ini...
Hi, i came across a program to config alternation function for SPI GPIO port A. GPIOA->CRL |= (11U<<20); // PA5 SCK AF output push pull GPIOA->CRL |= (11U<<28); // PA7 MOSI AF output push pull What does the 11U means? i know its somethin...
I have a project , used regular conversion ADC1 Vrefint Channel and Temperature Channel, and used injected conversion ADC2 extern Channel(ext.CH1 and CH2).ADC2 CH2 connect 2000mV voltage , CH1 is changed. If CH1 over 3.6V,the CH2 conversion is error...
I need to generate a simple CRC16 checksum from a unit8_t array[64] in javascript and validate the checksum on the STM32F373.I have been looking at the CRC unit and all of its options. I see STM32 use a non-standard scheme.Does anyone know of a samp...
I'm having problems with USB on NUCLEO-U575ZI-Q (STM32U575).I've created from scratch project in CubeIDE for USB CDC ACM device, and set up all th peripherals as in the example STM32Cube_FW_U5_V1.4.0\Projects\NUCLEO-U575ZI-Q\Applications\USBX\Ux_Devi...
Hello everyone i've been trying to use FMAMSDXX015WCSC3 force sensor. sensor address 0x28 and whenever i was trying to do IsDeviceReady function, its been always keep getting me HAL_Busy.HAL_StatusTypeDef status = HAL_I2C_IsDeviceReady(&hi2c2, 0x28 <...
I am trying to read some data by ADC using DMA transfer method I configured the ADC attached the code belowI cannot getting the ADC value in all buffer only read the 3rd buffer 1st and second buffer shows grabage value please help me i tried out ...
Hello everybody,Actually I'm working on a temperature sensor. This project works on battery (2 x 1.5 V alkaline).I would like to read the temperature in the room with an external analog sensor.But I don't understand how VrefIN works. Because my Vcc s...
