Posted on June 10, 2017 at 10:39I would like to enable the internal RTC of STM32F103 MCU. RTC works fine with HSE clock source. But when I select LSE as clock source, RTC stops working. It is necessary to use LSE and VBAT because the real time shoul...
Posted on February 27, 2017 at 23:01Hey guys.I'm trying to setup Custom HID. I'd like to use an output- and input Buffer.I have managed to setup the descriptors. I think i have done that right: Windows is correct enumerating my device.On the other s...
Posted on June 15, 2017 at 18:22I'm study cortex-m4 for semihost and use stm32f429-discovery board. I have a trouble with that semihost can not work when board is standalone(without in debug mode), So, I hope to use judge debug status before printf(...
Posted on August 29, 2016 at 16:09 Dear forum, i get this error after i tried to download the code to this board: http://artofcircuits.com/wp-content/uploads/2015/07/STM32F103C8T6-Development-Board-1.jpg I use a ST-Link V2 with ...
Posted on June 15, 2017 at 18:47HelloWhat is the analog input bandwidth of STM32F303? How does it change with sampling rate or resolution?
Posted on June 15, 2017 at 08:18Hi everybody!Recently I found a strange phenomenon that there was a peak on the rising edge when I using the TIM1's 4 chanels to be PWM output mode.And the maxium peak voltage can reach to 5.6V measured by the oscillo...
