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...
Posted on June 09, 2015 at 18:22 Hallo, I am working on extracting the data from the MP45DT I used PDM filter function. I gave a beep sound to the microphone in the certain frequency, but I noticed that the captured raw data is not g...
Posted on June 08, 2015 at 22:38Hi. I am porting an audio product that I designed and sell from the PIC32 platform to the STM32F401xc platform.I can read from the SD card using the 4 bit SDIO card interface using DMA2_Stream3 and FATFS vers 11.0.I a...
Posted on June 09, 2015 at 05:04Hi everyone,I have a STM32F072B Nucleo board (god knows why, should have listen to good advises -.-) and IAR Workbench with the 32Kb code limit version. V7.40.In an attempt to get more familiar with IAR tools I was lo...
Posted on June 07, 2015 at 19:46hi everyone i m going to interface encoder with motor the encoder is working perfectly and counting up to 0xFFFF in clock wise direction but when i rotate in counter clockwise direction it,s counting from 0 but from ...
Posted on June 09, 2015 at 17:24Hello, I would like to clock RTC with external clocking signal. The problem is, I have 10MHz TTL 0-5V signal at disposal but pins OSC_IN and OSC_OUT have TC pin structure (standart 3.3V I/O). I cannot simply reduce vo...
Posted on February 11, 2014 at 18:18 Hello, Today, we are using a STM32F405VG which is connected through I2S to a PCM interface of a Bluetooth Controller. The STM32F405VG and the Bluetooth Controller exchange audio data through this I2S with audio f...
Posted on June 05, 2015 at 21:16I am a Stm32 new learner.Recently I have had two Stm32 chips to communicated with eachother by using it wardware SPI.After I wrote the master and slave program and downloaded it into both stm32 chips.I used a logic an...
