Posted on August 30, 2016 at 11:56Hi,I'm trying to figure out, how to use the CubeMX generated project for touch sense aplication. I'm able to detect the change on the 3 touch buttons, but i can't figure out, how to detect on which touch button did ...
Posted on September 26, 2016 at 16:23I need to simply capture an input level and then output the same logic level as soon as possible on another pin.This can be simply done with EXTI, but I was wondering if there is a passive peripheral based soluti...
Posted on September 19, 2017 at 23:41I have a custom board using an STM32L452. I'm doing some testing of the ADC and am finding pretty high levels of noise.I have a rail-to-rail op amp driving the ADC pin with a 300 ohm resistor from the amp to the ...
Posted on September 03, 2017 at 23:44I have a custom board (2 layer) using a STM32F446RETx (3.3v) with STM32CubeMX, V4.22 with firmware V1.16.0. I am reading/processing MP3 files from a sdcard and there is a low-level but perceptible 'thump' in the...
Posted on September 23, 2017 at 07:34Dear All,I am configuring I2C for reading EEPROM address.I am using PB6_I2CSCL and PB7_I2CSDA pin and have connected EEPROM AT24C A2,A1 and A0 pin to GND. I have written following code to read the EEPROM but i am...
Posted on September 23, 2017 at 20:16 Hello, Currently, I am working on optimizing current consumption by using STOP Mode of the STM32L053C6T6 processor. I'm facing a problem that I can not get through, and I'm very happy if you can help. ...
Posted on September 08, 2017 at 14:46Hello,I want to implement an audio record based on STM32L4. To do that I want to use the SAI peripheral. By Referring to the STM32L4 datasheet the SAI don't support a microphone interface. So, in such case shall...
Posted on September 23, 2017 at 16:21Afternoon everyone,I'm not sure of how to do this, but I need to store a large amount of data on my mcu(around 4 times larger than the SRAM the mcu has), for a brief period of time. I'll be using the nucleo-F722Z...
