Posted on February 10, 2013 at 20:24 Hello, i am working on labview communication with bluetooth module driven by STM32F4, and some how i can't make it work. I can easy send data to labview, but not other way around, i have no idea where pro...
Posted on January 28, 2015 at 14:08 I’m having a problem with my project. The project is just a simple sound “loop�? It is a stm32f4discovery connected to a audio codec. They communicate over I2S3 in Full Duplex mode and the stm...
Posted on June 09, 2015 at 10:54Hello everybody, In my current project I need to establish an SPI connection between an STM32F407 microcontroller (slave) and an AD7763 A/D converter (master). Before the ADC actually starts sending any data, its two ...
Posted on June 08, 2015 at 13:03 Hi everybody, I use the function powf (that is supposed to return a float), included in the library #include <math.h> This is the definition of the function in math.h : float powf _PARAMS(( f...
Posted on November 13, 2012 at 14:37Hi, I am using the MCBSTM32E evaluation board to control some motors. I want to use my PC (Windows XP) to drive/record test data. Does anyone have an opinion on which interface is easiest to set up for communicati...
Posted on June 07, 2015 at 14:57Hello,I have installed STM32-MAT software and trying to generate and build code for STM32F4-Discovery. When I build model, it gives an error that it is not able to find any toolchain. This problem occurs because there...
Posted on June 10, 2015 at 09:09I have applied STemWin library on STM32F429 with LTDC peripheral and external SDRAM with controller FMC on TFT display 800x480 pixels (24bit RGB mode). It seems that everything works. Functions as GUI_FillRect, GUI_D...
Posted on June 09, 2015 at 11:42Last time I posted here to see if somebody can help me to solve my problem.I used two stm32 chips to exchange one byte data using SPI.But the data receiving from the slave was two bit or one bit wrong,such as 11110000...
Posted on June 08, 2015 at 18:53Hi folks,I find I am no longer able to download code to my target system (custom board) Using an IAR I-Jet on an SWD connector. The last code change I made was to add __WFI() to the end of my main loop.In this thread ...
Posted on June 10, 2015 at 00:16Hi all,I recently have configured hall sensors to TIM3 on the STM32F407VGT6 and have had success in using it to find an RPM speed based off the timer registers. However, I was wondering if there is a way to find posit...
