Posted on November 03, 2016 at 06:25I have an STM32F303 and I'm trying to connect 8 pins into an active bus to latch values via DMA. I need the pins to be high impedance inputs as soon as the device is powered, as it may be booted connected to an ac...

Posted on May 13, 2016 at 10:53Hi all,I am using an STM32F303 to sample PA7 via ADC2 when TIM8 update triggers it, and using DMA to put the samples in a circular buffer. Although I seem to have gotten things basically working in the code below, I am...

Posted on April 30, 2016 at 16:20I'm using the STM32F446 nucleo board and am trying to simply trigger a DMA transfer onto gpio when an OC triggers. Although I've done this many times on other boards (particularly F0 boards) I cannot figure out why i...

Posted on April 21, 2016 at 08:51Hi all,I am writing a program on the STM32F446 in which I am trying to talk with a PCM sound module via I2C. I am attempting to read its registers, which involves sending the register number and then reading the valu...

Posted on April 08, 2016 at 09:51On the STM32F303 I have a timer with an OC that triggers DMA events to write byte values onto GPIO. The DMA is set up with a cyclical byte buffer that is populated by the core via interrupt. For technical reasons I n...
