The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on March 20, 2015 at 11:39Hello, In multiple places in the UART HAL (in all the variants of HAL_UART_Receive) one can find the following code: /* Check if a transmit process is ongoing or not */ if(huart->State == HAL_UART_STATE_BUSY...
Posted on December 22, 2012 at 05:12Hi I have the STM3240G eval board. It has an OV2640 camera on it but I want to connect other sensors, say from Aptina. There is a camera connector provided but I was not able to find the male connector anywhere. I...
Posted on April 11, 2015 at 22:09I am working on a project that requires communication over UART. I am trying to get to the minimum time between UART messages coming in or going out that is possible. My problem is that sometimes the module gets into...
Posted on February 07, 2015 at 18:42 Hi I want to receive data from ESP8266 module after restarting it. But after restart, it starts the communication at a higher baud rate and after it's done booting it uses 9600 baud. When I have the UART p...
Posted on April 09, 2015 at 04:40Hi,Where can I find documentation on the UART registers for the STM32F429xx micro?The datasheet ( http://www.st.com/web/en/resource/technical/document/datasheet/DM00071990.pdf ), does not include any information abou...

Posted on February 13, 2015 at 12:04I wanted to have a simple slave device that could respond to a read OR write from a i2c master. the current HAL drivers don't support this so i added a few things to the HAL driver. the attached files are modified...
Posted on April 10, 2015 at 18:53Hello, I have a STM32F411 nucleo board and I would like to cut STLink out. I'm building a shield for nuecleo board and I want to add a SWD connector. So I look at CN4 on STLink and altium schematic and I have some d...
