Posted on September 10, 2015 at 07:48Hello Dears,We would like to share the 32.768 oscillator with STM32F405 mcu and with LPO pin of ST Bluetooth module SPBT2632C2A. Is it possible to connect the OSC32_IN or OSC32_OUT pin to LPO pin of bluetooth mod...
Posted on September 09, 2015 at 04:42I have a custom PCB with the STM32F429, and can set the BOOTB0 and BOOTB1 before #RST. My code asserts the Reset line for 20 milliseconds, so I hope that is long enough. Strangely, upon selecting the System Bootl...
Posted on September 10, 2015 at 19:10Hello, We are using STM32F051R8T6 microcontroller and IAR Embedded Workbench IDE. We want to know the time elapsed between breakpoints. How can I see during debugging the code? Thanks, Vimmi Adeshra
Posted on September 01, 2015 at 12:16 Hello, i have following code generated from STM32CubeMx. Transmit function returns HAL_OK status but under scope clock line stay always low. I have tried several codes to run this bus but always nothin...
Posted on September 10, 2015 at 15:28Hi all,I've just started playing with the STM32F4 on the STM32F401C Discovery board, and had some strange behaviour (slowed down time) when attempting to generate a 1ms TIM2 interrupt.From the reference manual fo...

Posted on September 10, 2015 at 16:06I have embedded experience with other dev board like TI tiva, NXP's LPC 1769 etc, however, this is my first foray into a STM board. my goal is to port my existing firmware to this board and I'll be glad if someon...
Posted on September 09, 2015 at 19:29good afternoon! i'm trying to prepare my system for realise updates to the user, and him can download it to the usb flash (used in my process all time) and as FW_update says rset-> press botton 4s-> wait until gr...
Posted on September 03, 2015 at 14:57I'm using flash memory in my project so in order the interrupts to work properly I have to move the ISR vector to SRAM or else the flash will stall the interrupts during its work. My working environment is CubeMX...
Posted on August 13, 2015 at 19:10 Hi, I am having trouble using an external pull up resistor to 5V. The voltage at the GPIOs is clamping to ~3.65V. Notes: Processor: STM32L151VBT6 (100-LQFP) Test Board: Proprietary ...
