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 13:05Hello. I'm new one here. Does anybody knows how to capture the signal (PCM) using STM32 Discovery via I2C slave mode. Other devices data:MCLK: 2MHzPCMSYNC: 8kHz (MCLK/256)PCMI - 8 bps #input-capture
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...
Posted on April 11, 2012 at 19:48Hi, I got two different devices with the microcontroler STM32F103RB which I'm trying to comunicate between them using the SPI protocol. The element A, is the master : The element B, is the slave : When I send from A(...
Posted on April 11, 2012 at 21:40Hi everybody, I'm new in STM32/Cortex M3. Commonly I create an application then write to chip's flash. Now, if I want to create an application stored in SD card then run that application. What the way for MCU do that...
Posted on April 11, 2012 at 18:48Hi everyone,I'm very new to STM32 Discovery and I want to do some project with it. I need to capture PCM signal(voice) from GTM382 modem before it reaches CODEC. I know there is PINS:MCLK - 2MHzPCMSYNC - 8 kHzPCMI -...
Posted on April 11, 2012 at 14:55I need to re enable interrupts in an interrupt service routine so I can do some I2C communication (my I2C driver uses the error and event interrupts). But I'm not clear as whether I should use CPSIE i or CPSIE f to ...
