Posted on August 09, 2013 at 20:11I'm working with the STM32F3 Discovery board. I'm wondering if it is possible to use a timer in encoder interface mode with the signals coming in on Channels 1 and 4. Do you have to use channels 1 and 2? Does the...
Posted on August 11, 2013 at 19:23Hi, I am using the STM32L-DISCOVERY evaluation board, and I made JP1 off as per the below instructions from the evaluation board user manual: JP1 OFF: the STM32L152 is directly powered, IDD measurement circuit is b...
Posted on August 11, 2013 at 19:01I've been looking at some board designs that I've found online, and it looks like some people include an external 8 MHz crystal in a resonator to run their clock. I'm wondering what the benefit of using this extern...
Posted on August 10, 2013 at 00:33Hi all,I've been playing with different peripheral examples of STM32L-Discovery on MDK-ARM (Keil) environment. Recently I'd like to move to linux with GNU gcc tool chain. I had a hard time learning to write a Make...
Posted on August 08, 2013 at 23:20 Hey guy's ! [I'd like to apologize for my bad englisch] I think I've made two mistakes in a row... First, I designed a STM32 Board with the usage of the Pin PA.15 - which is remapped after ...
Posted on August 10, 2013 at 04:51Hello, I am having a problem with CMSIS DSP. the state variables are represented in 1.15 format.I want to control the speed of a motor using PID algorithm.The minimum value of the PWM duty Cycle is 500 and it Maximu...
Posted on August 06, 2013 at 19:20 Hello all, I'm working on STM32W108xx & interfacing a sensor whose interrupt pin connected to the PB7, IRQC pin. How to configure this pin for the following handler ? void EXTIC_IRQHandler( void ) ...
Posted on August 09, 2013 at 10:15Hi, I accidentally configured USART2 to pins PA14 and PA15 with PA14 being also SWCLK. Now I can't upload code anymore. I read about putting the MCU into bootloader mode by setting BOOT0 to Vdd. But this doesn't wor...
Posted on July 16, 2013 at 05:15 So ive been trying to get the SPI interface working. Here's what i have so far. void SPI_Setup(void) { SPI_InitTypeDef SPI_InitStructure; SPI_I2S_DeInit(SPI1); SPI_InitStructure.SPI_Direction = SPI_Dir...
