Posted on December 10, 2015 at 14:50Dear all, I am using a STM32F103VEH micro-processor. I intend to put the processor into sleep mode and configure it so it will wake up by receiving any interrupt. I use the following code: uint32_t tmpreg = 0; ...
Posted on December 10, 2015 at 15:28 Hello there, I have a logger application on a STM32F407 device. I am saving logs to sd card. Generally it works, but I would like to make the procedure a bit faster by opening the file only once at the beg...
Posted on December 09, 2015 at 19:15Hi I am writing some data to an external device on the address and data bus I have used Stm32cube to set up the timing data. Once I have written the data to the device I have to strobe a data line. This is fine bu...
Posted on September 29, 2015 at 22:32I've tried compiling the included ticker example with the STemWin_HelloWorld project included in STM32CubeF7. Functionally, it works OK but the draws seem to be corrupted. Take a look at the video I've uploaded o...
Posted on December 10, 2015 at 06:28I'm using STM32F4 discovery board and I'm receiving 38 bytes on UART RX line periodically, since I want to transfer this in DMA I used DMA circular mode. But according to equation DMA_SxNDTR = Multiple of ((Mburst...
