STM32 MCUs Products

I'm using TIM6-DAC-DMAMUX-DMA to create a periodic signal as shown in the following picture. The yellow curve is DAC output, and green curve is a toggled GPIO for debug. I catched an unexpected interrption time point which is described as followed:

Registers Setting: DMA_S0CR: MSIZE=PSIZE=16bit, DBM=1, MINC=1, CIRC=1, DIR=M2P, TCIE=1, EN=1DMA_S0NDTR = 8DMA_S0M0AR points to a buffer: 0x8000, 0x6000, 0x4000, 0x2000, 0x0000, 0x2000, 0x4000, 0x6000DMA_S0M1AR points to a buffer: 0x7000, 0x5000, 0x30...

Chaining Timers (STM32F303CCT6)

Hi all!,I want to create a function for this:-Generate a number of pulses (pNumber)-With a period of seconds (nSec)-And a Duty cycle of 150msFor example, if I create that function "Signal(pNumber, nSec)", and then I call it:Signal(10, 200);I will hav...

ST32F413 undead DMA stream refuses to stop

I have a hang on the line below; the DMA stream seems unwilling to stop.Anybody seen this behavior before? Any work-around?Thanks!Best Regards, Davewhile(DMA2_Stream6->CR & DMA_SxCR_EN) {DMA2_Stream6->CR &= ~DMA_SxCR_EN;};

[L4 TIM1/8] TRGO driven from the plain OCxREF or the combined OCxREFC?

Posted on July 06, 2018 at 15:13The TIMx_CR2.MMS2/MMS bitr description indicates it's the former (OCxREF) whereas the figure indicates it's the latter (OCxREFC)Please clarify.Thanks,JWPS. One chapter further, the following picture probably by copy/p...

How to plot real time data in GUI.

I am trying to plot real time data in GUI.But when i run the program of GUI,it shows graph in MATLAB instead of GUI.I am just using command in GUI: run('matlab file name '). Code is written in matlab and calling this file in GUI.Thanks.

HRTIMER input frequency

Can the HRTIMER input frequeny be lower than the maximum value given in the datasheets? E.g. on a G74 with HRTIMER input at 125 MHz, steps would be nice 250 ps versus 188.2... ps at 170 MHz.The functional description "HRTIM timer is made of a digital...
