I have added the code written in HAL for I2C communication between I2C 2 of STM32L053R8T6 and LIs3dh accelerometer to receive whoami register. doesn't seem to be able to receive any data from the accelerometer.#include "stm32l0xx.h"#include "stm32l0x...
As title,all the startup script in the HAL V1.7.0 for F1XX chip contains the call to __libc_init_array , but the one for F105.Is there any particular reason or it is just a bug?thanks
I have an STM32F446 that has its firmware upgraded by another microcontroller through SPI-bus (please see AN4286, "SPI protocol used in the STM32 bootloader"). My application code starts at sector 4 (address 0x08010000) and I am able to successfully ...
Posted on June 21, 2017 at 15:04Hi,I've purchased the STEVAL-3DP001V1 board from ST, which is powered by a STM32F401VE. There is a jumper called boot which is wired as follow:So the pin BOOT0 is normally held high when the jumper is not fitted. BOOT...
My device use STM32L0 controller and Hal USB Device CDC class is implemented in it. When connected to Windows 10 OS the "Device description request Failed" message is shown. But on updated windows 10 OS it is working fine as it should. So is there a...
Hi,I have 2 eval boards STM32F756G-EVAL2 and STM32F779I-EVAL.I am using this example from STM32FCube library\en.stm32cubef7\STM32Cube_FW_F7_V1.14.0\Projects\STM32756G_EVAL\Applications\ExtMem_CodeExecution\ExtMem_Boot .I am able to run this sucessful...
Hi, guys. I'm curious whether anybody has tested the Opus Audio CODEChttp://opus-codec.org/using STM32F4 MCUs.I have both the NUCLEO-F446RE board & STM32F4 DISCOVERY board.Is there an example to play music using Opus?Any extra video demo for Opus usi...
Hi there,i managed the get a working composite device with working driver files. I can choose between all combinations of cdc,hid and msc.But i can't connect to my serial com port. I want to use this com port as a uart bridge but it's not working bec...
