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 September 16, 2014 at 13:42Hi,The STM USB HID stack generates an interrupt when new data have been received (eg 64 bytes). It is necessary to poll the status (using the USBD_HID_RecReport function), but this is no problem in my application...

Posted on September 19, 2014 at 23:43Hi everyone, This is my first post on this community, that i found great, so before everything let me say thank you. I'm currently working on a spare time project which involve some basic PID simulated control/pr...
Posted on September 23, 2014 at 00:25Hi,I found a possible bug in the generation of the code for I2C using DMA to receive data.When receiving data, the Rx callback is never called but the DMA-transfer is done correctly.The reason is that the DMA int...
Posted on September 22, 2014 at 08:05Hi This is a very general question. I am new to cortex M4 processors. I would like to know if I can use a piece of code written in a cortex M4 processor (say STM32F437VI) in any of ST's cortex M0+ or M3 processor...
Posted on August 07, 2014 at 07:13Hi all,I had an overrun error issue between successive calls to 'HAL_UART_Receive_IT()'.I know what causes the overrun, but shouldn't the following lines be added to HAL_UART_Receive_IT() to clear any pending error ...
