Posted on March 20, 2012 at 16:38Hi all, I have recently discovered the STMStudio and I'm trying to make it work with my F4-Discovery. The problem is that when I press play the program CRASH. I have my board attached by USB and ST-link is working go...
Posted on April 10, 2012 at 17:48Hi all, I want to measure the brightness using a light dependent resistor ''LDR'' uisng the stm32l15x devices. I an thinking to use the ADC to measure the ldr output but the the curve of the resistance vs illuminatio...
Posted on September 19, 2011 at 21:24Hi, i own an stm32f103 Board. USART1 is configured as TX via DMA and RX Polling. I tried to configure the USART2 port TX polling and RX polling. Confusing thing is that after sending on char to console the board...
Posted on April 11, 2012 at 20:46Hi, I`m working with the STM32F103XC processor (lqfp144 package) and I want to use the input capture mode for the Timer1. At the moment I didn`t get any timer interrupt while the I/O PE13 has a lot of rising edges. ...
Posted on April 12, 2012 at 09:32I'm currently developing a ''plug-in adapter'' using the STM32F205 that is to be used in a variety of legacy designs. These old designs all rely on 5V components and at least some of them require bidirectional commun...
Posted on April 12, 2012 at 23:01I'm using a STM32L151C8 with ARM RealView and ST peripheral libraries. When I try and configure an I/O pin as an alternate function it does not write the alternate function selection to the GPIOx_AFR register. After ...
Posted on April 11, 2012 at 14:08Some STM32F1 MCUs have Flash Dual Bank, provided total amount of Flash is bigger than 512 KB. Thanks to that they posses valuable ability to ''read-while-write'' (RWW). Do MCUs from STM32F2 or F4 series have this fea...
Posted on April 12, 2012 at 10:21Hi, I am disabling SDIO Clock in RCC module after each block write and enabling before. Some card works property, but some give response timeout after command: SDIO_CmdInitStructure.SDIO_Argument = (uint32_t) Bl...
Posted on April 10, 2012 at 08:12Hi,I am having difficulty getting sysclock to work at 24Mhz using HSI and PLL.I am also facing difficulty in getting USART3 to transmit something.I have seen and tried what other members on this forum , with similar ...
Posted on April 03, 2012 at 06:52I have a project involving STM32F103RE. A timer channel TIM2_CH2 triggers a continuous read on ADC1, which uses DMA1 into a buffer. What I want to do is set up ADC3 to read a different channel in a similar fashion us...
