Posted on June 11, 2018 at 23:16Hi,I have very weird issue with external voltage reference with STM32L4xx.I have a board which is using external voltage reference for STM32L476. I apply 3.3V to both VDDA and VREF+. The VDD is also powered with 3.3V....
Posted on June 11, 2018 at 06:36I have a project that is a series speakers. There are 2 speakers master speaker (MS) and slave Speaker (SS)I want to design the MS as following function.1) use phone as controller through Bluetooth2) MS with SD card...
Posted on June 08, 2018 at 14:40 Hello everyone, I have 9 pins of ADC that each of them will received signal from function generator 20 kHz. I want to use ADC to store the data inside an array by using DMA2. ADC1 has 3 pins, ADC2 has 3 pins, ADC3...
Posted on June 11, 2018 at 17:32I am developing an battery operatoad device, but at most of other IC are opearting form 1.8V that I would like to run STM32 from 1.8V as well. But batttery will be 3V, as other things need 3V as well. So qusetion is -...
Posted on June 11, 2018 at 15:23Hello all,I am using STM32L432KB controller with LIS2DE12 accelerometer over I2C3.On the controller side,- when I use Normal mode (100KHz) with blocking API HAL_I2C_Mem_Read(), it took about 500 uSec to read a single ...
Posted on June 11, 2018 at 15:02Hello, I would like to know exactly how HAL_UART_Receive_IT() API works ...?I am using STM32L432KB controller with Quectel's BG96 module to send AT commands and receive its variable length responses.A demo code of my ...
Posted on June 10, 2018 at 21:20Hey guys.I have to design my own PCB for my project. How can I get information about how to design a good PCB and the notes about how to reduce noise?And Is there any Forums like ST forums for Altium? If it is would y...
Posted on June 05, 2018 at 10:42 Hello, I'm working on a project that aims to develop a program for compliance with the TS13 149 ( http://itxpt.org/en/home) standard of passenger counting systems for public transit vehicles produced by the compa...
Posted on June 11, 2018 at 12:14 hi, I'm using cubemx to initiate the project, the mcu I'm using is stm32L053C6. To that I have 2 sensors and 2 transistors connected to adc inputs. The code below shows how I get the input value, voltage, f...
Posted on June 09, 2018 at 08:55Hi I use DMA in Interrupt mode to receive data from UART Periph to memory. data is transfered (my destination memory is occupied correctly)but my DMAReceiptComplete() callback function is never called./*--------------...
