Posted on January 13, 2014 at 00:03Hi,I'm new to the STM32 processors and I'm using the Microexplorer tool to figure out the pin and device assignment. Unfortunately it seems like it isn't possible to activate an additional timer, which I need to ge...
Posted on January 13, 2014 at 00:40Hi, is it possible to trigger a DMA transfer (8 bit data from gpios) on a falling edge on a gpio pin? (without using interrupts!!!). I think it is standard on all other mcu's with dma support (like kinetis mcus or ...
Posted on January 11, 2014 at 23:08Hello,I will try with this forum as a last resort for my problem, namely getting my NAND memory to play with me.http://www.ic-on-line.cn/download.php?id=1915099&pdfid=5E619D21E0C125A4A94BC1A860068896&file=0459\h27u...
Posted on December 06, 2013 at 09:35Hi together,I have a couple of STM32VL-Discovery boards, with each holding the same firmware. The firmware essentially does nothing more then sending 8kb of data over UART.Furthermore, I have a custom controller b...
Posted on January 13, 2014 at 14:46 Ok, I got the LoopBack to work. But, now I can not get it to work in Normal mode. I have it running on (2) Stm32f103C8 chips. I have a mcp2551 attached to each board, and the mcp2551 chips cross connected. But ...

Posted on January 13, 2014 at 13:29 Hi, I am running USART3, on 921600 BaudRate, using RTS CTS, I am always facing system hang when I try to do RX and TX simultaneously. I have pasted the main and IRQ code. IRQ is designed to Transmit a c...
Posted on January 11, 2014 at 13:49Hi all,I want to detect a falling edge on external pinn let's say PD13 by hardware but without using the interrupt capability (using EXTI + NVIC).At first time I thought it is possible to do that using EXTI only by...
Posted on January 06, 2014 at 10:15Hi all,I'm trying to receive char using USART through interrupts but it seems doesn't work (it doesn't receive the interrupt when I prompt a char in the terminal).I use USB To RS232 TTL UART PL2303HX for connect st...
Posted on January 11, 2014 at 17:28HelloI am trying to implement indirect voltage measurement in a battery operated application.Our MCU supports VREF+ and VREF+ is derived from the battery voltage. Therefore - VREFINT must be used to extract VREF+.T...
