Posted on April 24, 2016 at 06:25Simple question If I set some interrupts priorities to 0, should I expect time measurements (down to the microsecond) to be inaccurate? ( using SystemCoreClock and SysTick->VAL )
Posted on March 28, 2016 at 18:59Hi,I would like to share an idea here about a way to auto-test our boards (based on STM32F215 LQFP64) to prevents shorts in both contexts:1. after reflow process as partial QC,2. during the product life: after each s...
Posted on April 28, 2016 at 07:44I'm using the STM32F105R8 on a custom 4 layer board. Boot0 is pulled to ground via a 10k resistor. Boot1 is floating. The board is based on some open hardware with associated open source software. I'm using the sa...
Posted on April 26, 2016 at 08:28hello I get overflow on DCMI .please see my code.DCMI config : hdcmi.Instance = DCMI; hdcmi.Init.SynchroMode = DCMI_SYNCHRO_HARDWARE; hdcmi.Init.PCKPolarity = DCMI_PCKPOLARITY_RISING; hdcmi.Init.VSPolarity = DCMI...
Posted on April 28, 2016 at 15:20Dear all, I have problem transferring relatively large block data (>= 600 bytes) over USART. All blocks smaller than 600 bytes can be sent successfully from MCU and the host at the other end receives that correctly. ...
Posted on April 28, 2016 at 08:31Hi, i want to design the mapping of my board. I need CAN3. In the STM32F767 Datasheet an unconsistency. In chapter 3 Table 10 (pin and ball definitions) is descriped that at pin PA8 the CAN3 is possible as alternate ...
Posted on April 27, 2016 at 13:45 Hello, I am trying to handle I2C bus errors on the master side => get the I2C bus working again after detecting an error. (MCU: STM32F407) In the following test, the master send an Address + Read c...

Posted on April 27, 2016 at 14:25Hi, I have a custom board based with STM32F401 MCU. While programming the board with OpenOCD, it somehow failed and now the board is with ROP. I'm trying to figure out why the MCU gone to that state. Any ideas why? T...
Posted on April 27, 2016 at 11:10Hello, http://www.keil.com/support/docs/3778.htm describes a nasty bug when single stepping in Cortex M7 up to r0p1. I am hit by this bug with my F746 boards, as the core revision is r0p1. Two questions: - will STM...
