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 August 18, 2017 at 02:58 I'm having a really fun time learning this stuff! I have my WWVB decoder working with EXTI and TIM2 free running . As a learning exercise, I was trying to use the PWM Input Capture method. TIM2 prescaler i...
Posted on August 18, 2017 at 04:30Hi,I've got problem with migrating from stm32l476xx to stm32l451, when using l476, writing to internal flash was never been a problem. But in L451, I've failed everytime I write to the internal flash.I've notice dif...
Posted on August 18, 2017 at 01:13So, I have a system here that I recently observed a non-reproducible lockup in, so I rushed over and attached a debugger to the running target to see where the problem was.I saw that the UART driver code (at an SDK ...

Posted on August 17, 2017 at 17:071. As I see on stm32f4 discovery DK schematic, CN4(audio jack) only connect to HP/LINE_OUTA and HP/LINE_OUTB ( Pin 14 and 15 of CS43L22). Because of that, I only use OUTPUT_DEVICE_HEADPHONE of CS43L22. Does my thoug...
Posted on August 17, 2017 at 12:59Dear all,the readout protection of the L4, F4 and F7 MCUs is supported with build-tools form Keil and IAR. The 3 application notes, i have read, states that one of these IDEs must be used. Since the newer arm-none-e...
