STLINK Utility V4.0.0 problem
Posted on August 09, 2017 at 04:04Hi, I am currently playing with micropython on NUCLEO-L476RG and get it flashed and working using STLINK Utility V3.9.0But then when I update to STLINK Utility V4.0.0, using the same exact .HEX files, It stop workin...
Why it always takes 12 clock cycle while using the STLINK to trace single instruction's execution time?(about dual-issue, St-link and Cortex-M7 pipeline)
Posted on August 22, 2017 at 12:25The device is STM32F746NG-DISCO, and I measure the execution time of single instruction by this ways:int a=0; int b=255;while(b--) { a++; }make breakpoint and watch the value of States. And by this, I found that for...
stm32f042f6 spi doesn't work with HSI as PLL source
Posted on August 20, 2017 at 21:37Hello! I'm using spi peripheral on STM32f042f6p6 and faced with strange situation: spi works only if system clock is PLL and HSE is PLL source. I have tried HSI, HSI48, with them spi does not work at all: neither tr...
STM32F4 HAL for TIM PWM and Encoder Input
Posted on November 09, 2015 at 05:13Hello, I am trying to use the STM32F4 HAL Drivers to read a 50 Hz PWM input signal and an A quad B encoder signal on an STM32F4 Discovery board, but the TIMx_CNT register is NOT incrementing on the external trigg...
SPI DMA transmit during interrupt
Posted on August 22, 2017 at 10:37Hello!I am implementing a state machine which is driven by interrupts on the STM32F437IIT6.The interrupts occur as a result of using the HAL_SPI_Transmit_DMA() function.While testing my program i have noticed that w...
how to get more info after watchdog reset
Posted on August 22, 2017 at 09:46We are using quite a few stm32 MCUs from 401 to 439, and our program becomes more and more complicated. In order to avoid possible deadloop, we have used watchdog to rescue the system, basically it is working well n...
