Posted on December 31, 2016 at 00:27Hi, all, I have a STM32F7 Discovery board (chip is STM32F746NGH6 ). I have implemented my own SDMMC layer (bare metal, no HAL or ported STD peripheral libraries. It is working very nicely using polled mode for SD...
Posted on March 30, 2017 at 17:19Hello, I have a STM32F334 on which I use the HRTIM1 in a SEPIC converter.The PWM section works the way I want it to, but now I want the system to stop in case of a Hardfault. But for some reason I can't get this to w...
Posted on March 31, 2017 at 11:25HiI am new to freertos.How do I measure time spent in IDLE loop? Where is the IDLE loop anyway?What are the most important debug variables in FreeRTOS?Does Freertos comes with MIPS measurement functionality?THX

Posted on March 30, 2017 at 21:18The board can't function properly, it can be downloaded using ST-LINK but the output doesn't match with the program I wrote. Is it because the oscillator? I watch the oscillator signal and it is different from the ri...
Posted on March 31, 2017 at 08:57Hi,I need to use a timer period between 2 us and 500 s, so using the timers inside an STM32F7 I calculated that slowing down the bus of the timer to 8MHz I can cover all the range with differents values for the presc...
Posted on March 31, 2017 at 07:05I am trying to get some high speed PWM DMA code working on TIM4 CH3 and TIM4 CH4. I can get theTIM4 CH3 signal on D10 but the TIM4 CH4 on D9 doesn't output anything. Is there some hardware limitation ?
Posted on March 31, 2017 at 03:42mcu: stm32f100vctI am using spi3 and i2c1 together.However, when i2c1 is used, no signal is output from mosi of spi3.If i2c1 is deleted, spi3 will operate normally.If i2c1 and spi1 (remap) are used, I2c SMBA does not...
