Posted on September 11, 2015 at 13:23Hi ,I'm using STM32F103 and i have an input signal on Timer1_ch3 (PA10) which generates an EXTI interrupt and it's working well.I have another input signal on Timer2_ch3, but something strange happens when i conn...
Posted on September 10, 2015 at 17:17I'm trying to use SPI with DMA and have had an issue in that data packets are sent too close to one another, based on the SPI stall time needing to be 2us between packets. Is there anyway I can set this through t...
Posted on September 08, 2015 at 09:22Hi to all, I wanted to start a project using STM32 MCU and I would ask where can I find the first basic instruction. I have a STM32F0 board, but I don't know how to interface with pc. I downloaded ST_LINK, and I ...
Posted on September 04, 2015 at 20:18 Hello! I have a problem with low power mode on stm32f103 and stm32f4 When I try to put them in Stop mode they still consume about 4-5mA which is too much ( it should be about 300uA). Here's the imageh...
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...
