Posted on September 27, 2016 at 17:11Dear all,I am using STM32F4 Discovery board and have some problems with using DMA on USART. The cause may be the unwanted left behind data inside USART RDR.Would you please kindly give me instruction how can I fl...
Posted on September 21, 2016 at 15:56Since firmware version 1.13 there is a big issue with debugging. The firmware starts the watchdog during initialization. This result in reset when a breakpoint reaches. Before this version, I could start the IWD...
Posted on September 24, 2016 at 16:20Is there a new version of the Errata document? The one the website (Doc ID 027036) is revision 1 and was released on 20-Oct-2014.Why do I ask? The STM32F412 - has an Errata about DMA2 corruption when managing AHB...
Posted on October 15, 2014 at 10:33Hello, I use a STM32F4-DISCOVERY Board in master mode, which should communicate with a slave via SPI. Basically, the communication is working, but the last bit on the MISO line is always lost. For example, if I rec...
Posted on September 27, 2016 at 09:56Does anyone know if it is possible to get STM32 CubeMX to generate a project that is ''predefined'' to be loaded using a bootloader?Essentially, this would involve being able to specify the program load address a...
Posted on September 26, 2016 at 18:14In separate applications I have managed to control the mouse, and the keyboard using the stm32f042. How do I go about combining the two in one application?I would like my stm32 to be treated as both a keyboard an...
