Microsecond delay using timer in stm32L0
I want to generate the microsecond delay for stm32l083cz.when I using the configuration PLL clock ...32Mhz freq to APB1 which is connected to timer2 PSC -- 32-1 and Period 0xffff-1 Its working perfect and i am able to generate the microsecond delay.B...
Resolved! First timer delay missing -- AN4776 wrong?
I'm new here but have already gotten lots of good advice, so I'll press my luck and ask another question. Can't believe it hasn't come up before, but search doesn't find anything.Simplest possible timer example. Start counting down from ARR value, bu...
Resolved! Timer Configuration
Hi, I am using STM32F779NI for development. My requirements are:On PD15, i.e Timer 4 channel 4, I want to generate a PWM output.On PB7, i.e Timer 4 channel 2, I want to use it as an Input capture functionality.Is it possible to configure the Timer fo...
PWM -> ADC & DMA
Hi, I want to trigger ADC with PWM, transfer it to array by DMA.But first I have problem with setting dma.......Question 1.Do I have to start HAL_ADC_Start before I use HAL_ADC_Start_DMAOr will this second function start adc & dma?
I2S Clock vs Sampling Frequency(Fs) for sampling MP45DT02 on STM32F4 Discovery
Hey everyone,I'm trying to send a 1.024MHz clock signal to the MP45DT02 microphone peripheral on the STM32F4 Discovery Board using the I2S_CLK of the I2S interface. To do so, I'm using the following prescaler configurations: HSE_Value = 8MHzPLLM = 8 ...
f103 LL spi DMA not interrupted
hii use f103 to read ad7606 with spi i see cube example for LL( hal spi has delay)i want read two out of a2d so i config spi1 master receiver and spi2 slave receiver clk of spi1 and spi2 and a2d connect together out A connect to spi 1 and out 2 conn...
QuadSPI instructions coming out IO1, not IO0 (and other issues)
So, I am getting my feet wet with QuadSPI on an STM32L412RB, talking to an external FLASH memory part (GD25Q256D, if that matters). I've got some plausible code written to "hello world" the chip, and my trusty salae hooked up, and am seeing some wei...
STM32F030F4P6 EMI problems?
Hi,I designed a board with a STM32F030F4P6 on it. The board is about 68x48 mm and contains the microcotroller a AC/DC supply and a nRF24L01 RF-Module. supplied directly with about 5V from an external supply the circuit works as it should. But when I ...
