STM32F407VGT6 external oscillator
Posted on July 19, 2016 at 13:19Hi everyone, I have designed a board using stm32f407vgt6 and placed a 8MHz crystal oscillator with 22pF capacitors. The code I wrote works perfectly with stm32f4discovery. But when I try to use my board, it can't init...
DMA problem ?
Posted on July 19, 2016 at 13:58Dear All,I am facing a strange problem. I am using a slave SPI to transfer memory data by a DMA stream. The transfer uses 16-bit wide data. On the stm32f429 (m4) the code works very well and I can use the data. The sa...

Read analog Value from non ADC input (GPIO-Analog mode)
Posted on July 19, 2016 at 09:11Hello, I�m a bit confused about the documentation from the GPIOs. It says that all GPIO can be put in analog mode, so my assumption was that I could use all of them as analog input. However, nowhere in the GPIO chapt...
I'm using SPL still - should I go to STM32Cube now? (experienced users opinios)
Posted on July 09, 2016 at 15:04Hi everyone,So I usually check a bit of the forum with issues related to the STM32Cube and opinions, but I haven't done that in a while.So I would like to hear the opinion of some veteran users about how the STM32Cube...
