Posted on January 10, 2016 at 00:31Hello everyone, I wanted to make some applications on STM32F746-DISCO with use of WM8994 codec and I decided to start with making a working pass through audio - connect to jack input sound source and listen to it o...
Posted on January 04, 2016 at 15:59Hi,I was hoping that I might get some clarification regarding the EXTI on the STM32F207. Looking at Fig 4 (STM32F20x block diagram) within the datasheet, it would appear to be APB2; this seems to be further confirm...
Posted on January 09, 2016 at 14:05Hey world! I use STM32F745 in my project. High-speed ADC connected to GPIO port. ADC and MCU clock from 25 MHz generator. Also clock signal goes to GPIO port. The MCU clock frequency is 200 MHz. I've realized the t...
Posted on January 09, 2016 at 15:20Is there an netmf, that can be used for STM32 F4 Discovery Kit with STM32F407 MCU like .NET Micro Framework on the STM32F429 Discovery kit ? Can NET Micro Framework environment for STM32F4 microcontrollers for M...
Posted on January 08, 2016 at 22:58 I have a target board that is based on theSTM324x9I_EVAL, I need to use 2 UARTS, I set up UART4 and USART1 both at 1200 BAUD, my clock is 180MHz with HSE of 25MHz. The strange thing I'm facing is that (...
Posted on January 08, 2016 at 23:50 Hi, I'm attempting to read an I2C device withHAL_I2C_Master_Receive_IT(). A logic analyzer shows the data coming across the I2C bus, but where does it go? This is a st32f405, IAR, and CubeMx generate...
Posted on January 08, 2016 at 22:57 Hi, I'm a newbie, and I have just started working with STM32 and the GNU tools available, and can anybody explain what is correct from the following quote on how to install which is on ( http://gnuarmec...
Posted on January 08, 2016 at 18:58I have an F7 processor that I cannot get out of sleep. I can communicate with it using the ST-Link tool, however I am unable to debug the part anymore. The JLINK unlock tool does not support the F7 parts yet. Ca...
