Posted on July 06, 2015 at 14:20 hi everybody! I'm developing on st32f0 a device with two analogics sensors. After the initialization, I can read properly one value but the other is always at it s maximum value (4095 for 12 bits of data). ...
Posted on July 07, 2015 at 20:13I've seen at least two other threads with an inverted DAC concern being present, wondering if anyone has more information o the issue? I have 3 identical boards in house populated with the F4, one of which has an inve...
Posted on July 07, 2015 at 17:00 I used STM32 cube for the PLL configuration // Enable HSE Oscillator and activate PLL with HSE as source RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_...
Posted on July 07, 2015 at 18:18I've been testing a STM32F4 Discovery since I'm new to ST Microcontrollers and I wanted to use one timer to measure 4 different channel frequencies, as I want to measure more signals than there are timers. I do not ca...
