Posted on October 20, 2015 at 22:05Hello could you please help me with my question about backup SRAM in STM32F427? I have design, where I am using voltage regulator for VDD and VDDA - 3V0. As backup I use batery 3.2V connected to VBAT pin6. My qu...
Posted on October 22, 2015 at 00:24Good day everybody, I'm having an usual problem on STM32F407 SPI. I'm using a STM32F407 discovery board with a custom made breakout board (SPI2 pins used are PB13, PB14 and PB15 and are connected to a AD7190 AD...
Posted on October 21, 2015 at 22:02Hello could ypu please explain me how can I check from Order number of STM32F427VI which revision (HW revision) in this chip? In datasheet I can check, that for STM32F4xxx exist several HW revisoon of silicon chip:...
Posted on May 22, 2015 at 11:33Hi,help me please to set up the SAI correctly.I need a mode I2S standart, 32-bit frame, 24-bit data. I configured my code: hsai_BlockA1.Instance = SAI1_Block_A; hsai_BlockA1.Init.Protocol = SAI_FREE_PROTOCOL; hsa...
Posted on October 10, 2015 at 17:31 Hello, I've the following configuration on my STM32F4: - ADC with DMA triggered from TIM3 - EXTI0 triggered fromGPIO PA00 - EXTI1 triggered from GPIO PA01 The interrupt EXTI0 and EXTI1 s...
Posted on August 27, 2012 at 20:01Is there a way to tell a TIMer on STM32 chips to do some number of steps and automatically stop after finished (and give an interrupt)? I can do it now with a counter in the ISR but a few pulses slip out before I c...
Posted on October 20, 2015 at 15:51Hi, all. Could you please recommend the best way to do that using STM32 Timers? Input signal is a 5-10 kHz 3V sine-wave, and high-stable TCXO 12 MHz is used for MCU clocking. Measurement should be done with 1E-3 H...
Posted on October 21, 2015 at 21:21My colleague uses STM32F373 and he found a strange behaviour with SD AD. Actually, this behaviour is described in ref. manual, but I am just curious why it is like that...He starts SD AD conversion with software co...
Posted on October 18, 2015 at 15:52Hello,I have a STM32F4-EVB-V2 Board with MCU STM32F417IGH6. I want to display a BMP picture from SDcard to TFT LCD. So I have used an example ''Display/LTDC_PicturesFromSDCard'' from one of the STM324xG_EVAL's app...
Posted on October 21, 2015 at 17:40Hello! We are trying to generate a clock signal around 1.024MHz. We currently have a 32768 watch crystal connected up and are hoping to get at least the 0.5% accuracy as alluded to in the reference guide:Multispee...
