Posted on December 15, 2016 at 08:40Hello everyone, Can anyone point me how to use printf() for this specific environment?I did the following so far:1. Initialized UART3 since it's connected to the USB2. I am using HAL_UART_Transmit(&huart3, &data, ...
Posted on December 14, 2016 at 08:44Hello Team,We are working on one project, and we are planning to use STM32F103RGT6 and STM32F205RGT6 MCU.but before that we are testing our application using STM32VLDISCOVERY board and this board is working good.N...
Posted on December 15, 2016 at 03:39Hi, we use STM32F407. STMFlashLoader is V2.8.0. I use STMFlashLoader Demo.exe successfully if I set Boot0 to 1.For some reasons, I need to test the STMFlashLoader.exe using the command line to download the firmwar...
Posted on October 30, 2016 at 18:47Hi, The latest STM32L0Cube UART Hal pulls in unnecessary floating point code when initializing the UART. The culprit is the __DIV_LPUART macro, which contains a floating point number (256.0). When replaced with the...
Posted on December 11, 2016 at 11:25HI All,I am wondering why initial code size differs with a factor of 3 between the STM32F031K6 and the STM32L031K6 - just for making an LED blink.I use CubeMx to generate the project and GCC (OpenSTM32 AC6 IDE) to...
Posted on December 14, 2016 at 13:39 Hi all. I noticed that when debugging a STM32F091 MCU my systick ISR never gets called. I Use STMCube library, so HAL_GetTick and HAL_Delay ceases to work as well (because uwTick is not increased). But onl...
Posted on December 13, 2016 at 19:43I am using STMFlashLoader Demo v2.8.0I recently upgraded as I am bringing up a new board design that uses STM32F427. I am unsure if these issues exist in previous versions, but the first issue probably does.Issue ...
Posted on December 14, 2016 at 20:22Referencing P 1484 RM0385, Table 247 (Rev 6 of this RM.)The table shows bits for the operation field to be 10 or 01. I'm wprking with an Ethernet PHY that has extended function registers which are addressed by set...
Posted on December 09, 2016 at 13:36My IDE has a feature that uses less contrasting text for code that is 'inactive' (not included) from this I found that some code is not being included that i had expected to be. For instance stm32f0xx_ll_tim.c &...
