Posted on December 30, 2015 at 12:33 Hi, I have a question regarding SYSCFG_CFGR3bit definition. I'm using stm32l051xx.hV1.4.0 and Reference manual RM0377 /DocID025942 Rev 4. Some bits seems to be defined in reserved area of SYSCFG_...
Posted on January 04, 2016 at 16:11Hi, We are using STM32L051C6 microcontroller in our design. We also use the STWD100 Watchdog chip too provide a reset when the code hangs up. This is added as a redundance to the internal watchdog chip of the micro...
Posted on January 05, 2016 at 08:20LwIP works with all default settings if FreeRTOS is not enabled. Adding a single MX_LWIP_Process(); in the main loop makes the board pingable. If FreeRTOS is enabled, it gets stuck at HAL_Delay() during the initial...
Posted on January 05, 2016 at 15:30I try to make work tft with stm32f4discovery via fsmc, but I can't find any examples for new version of HAL files (stm32f4xx_ll_fsmc.h instead old stm32f4xx_fsmc.h). All old examples has some differences with new. ...

Posted on January 05, 2016 at 15:39In reference manual RM0390 for Incomplete isochronous IN data transfers Application programming sequence there is step 3:3. The application must read the Endpoint Control register for all isochronous INendpoints to...
Posted on January 05, 2016 at 11:29Hi all.I'm getting in trouble with STM32F070 RTC-based features availability.Is the periodic wake-up on RTC feature available?Reading datasheet and on-line feature description seems that is present, but HAL documen...
Posted on January 05, 2016 at 11:53Hi, I recently tracked down an issue with PA15 staying high during Standby (and therefore holding an external component in reset). It only happened in debug builds where we need the debugger to stay attached during...
Posted on January 05, 2016 at 02:42Hello all,I am new around here; please excuse in advance my probably boring query... I have a custom board with an STM32F427ZI together with 256Mb of SDRAM (the chip is an AS4C16M16S). I configured it with the code...
