Posted on October 26, 2016 at 14:11I'd like to transfer data from STM32F446 MCU to an array of ST1642GW LED drivers efficiently. Right now, I do so by a soft SPI interface which is limited in speed and consumes too much CPU time. The real challeng...
Posted on October 24, 2016 at 09:56 I have just updated to Cube v4.0 which I also think updated the firmware package for the chip I am using (STM32F030RCTx). There is a bug in the initialisation code for the DMA that causes the project not to be...

Posted on September 17, 2016 at 15:15 hey guys, so I am using an STM32F411 as an USB device. It's connected via VCOM to a PC. I am using HAL V2.4.1 from19-June-2 In general it works good, but when I quickly connect and disconnect the u...
Posted on October 26, 2016 at 09:31Hi All...i using stm32f103rbt and Ds18B20 temp sensor.i search for hardware peripheral driver that make 1wire independent from cpu but not find any thing useful.i want to read temp from ds18b20 without delay. how i...
Posted on October 25, 2016 at 18:06 Hi, In my quest of low power, I'm not that far from my needs but there's still something I don't understand: RTC is clocked by LSI, while SYSclock is clocked by HSI. __HAL_RTC_CL...
Posted on October 22, 2016 at 20:25It's strange but http://www.coocox.org/ do not work. Maybe there is a site from which this distribution can be downloaded? Besides http://www.coocox.org/. Thanks.
Posted on October 25, 2016 at 11:50Hello everyone,I am implementing a SD card-reader like device on my custom board with STM32F756 with SW4STM32 (AC6).Up to this date, I have successfully completed a working link to read/write file from the PC to SD...
Posted on October 18, 2016 at 02:28I'm trying to start/stop a PWM signal to an LED (simple test!!). Using HAL_TIM_PWM_Start() starts the PWM output, HAL_TIM_PWM_Stop() stops the PWM but leaves the output in a random state rather than the (expected) ...
Posted on October 25, 2016 at 18:12Hi, I was trying to attach a AK4554 codec to a STM32F091CB using the SPI/I2S interface when I discovered it is half duplex only. I don't want to change to an F4 with an SAI interface if I can help it, as it is over...
