Hello,
Me again with basic questions.
I am still trying to acquire from a bank of ADCs. 8 SAR ADCs in parallel on my stm32f429i-disco. From previous forum posts, and my own attempts, it appears I canno...

Hello,
For a project I am working on I would like to generate interrupts on both edges of the HSI clock, for synchronization purposes.
The sysclk is based on the main PLL, sourced from HSE.

Hello.
I am currently trying to build a project using the STM32F429 iDisco.
The toolchain I am using is the arm embedded gcc, under Eclipse IDE.
I am trying to use STM32Cube to write the ini...

Here are my current DMA init settings:
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);
DMA_InitStructure.DMA_Channel = DMA_Channel_6;
DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)GPIOA;
DMA_I...

If it where me I'd just burst in the entire 16 byte run, and be done.
How would I go about doing that, exactly? Settings wise I mean. Would this work:
TIM1->RCR = 0;
TIM1->DIER |= TIM_IT_Update ...

By the way, this is my DMA config code
//USE registers from DMA2 and DMA2_Stream5, channel 6
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);
DMA_InitTypeDef DMA_InitStructure;
DMA_InitStructure.D...
Posted on March 29, 2014 at 20:52Thank you for clarifying.I have a further question. I am looking for this information in the reference manual but I cannot find it.Suppose I connect all my ADCs to GPIOA[0...7]. Then I set the DMA to read bytes and s...
Posted on March 29, 2014 at 19:29The DMA can read a single pin, or up to 16 within a bank. If your data is sparsely distributed in the pin bank you'll have to process the half-words and extract it. DMA is not smart, and you'd need one DMA unit (stre...
