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...
Posted on August 22, 2015 at 20:27Hi. I have three buttons connected to PB12, PB13, PB14. I use the following code: GPIO_InitStruct.Pin = GPIO_PIN_12 | GPIO_PIN_13| GPIO_PIN_14; GPIO_InitStruct.Mode = GPIO_MODE_IT_RISING; GPIO_InitStruct.Pull ...
Posted on October 21, 2015 at 19:20Hi,I am using STM32F746.It is connected with ST wifi module(SPWF01SC) via UART./* Buffer used for transmission */uint8_t aTxBuffer[] = ''AT+S.SOCKD=8825\r\n'';/* Buffer used for reception */uint8_t aRxBuffer[RXBUFF...
Posted on October 21, 2015 at 10:25Hello. I'm using an STBee evaluation board that has STM32103VE.I accidentally overwritten the bootloader using the ULINK2 debugger using Keil.I thought there should be no problem since I have the DFU hex file but a...
Posted on October 21, 2015 at 13:26 I'm experiencing a problem very similar to the post titled ''Design Anomaly with TIMx...'' using the STM32F429i-DISCO Board and IAR Workbench. Despite several related posts, I have not found a solution. My 2-ch...
