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 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...
Posted on January 11, 2014 at 19:31I've a small query about programming ADC in regular dual simultaneous mode. I'm using stmf4 discovery board.Though I've configured ADC1 channel 11(PC1) and ADC2 channel 12(PC2) in this mode using dma. But I've to c...
Posted on January 12, 2014 at 01:29I am using a STM32F4's internal CRC peripheralMy test sample data works against the code available at http://www.opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/libkern/crc32.cSample data is { 0xA1, 0x11, 0xC0, 0...
Posted on January 11, 2014 at 12:51Hello everyone,I would be very gratefull if you help me with this or give me some idea. I have problem with STM32100RB USART module. It uses Cortex M3 and I am developing in Keil uvision.The USART uses hardware flo...
Posted on June 18, 2012 at 13:32I am using the STM32F4 family with Atollic TrueStudio and would like to use the CMIS DSP_Lib for my application. The STM32F4xx_DSP_StdPeriph_Lib_V1.0.1 directory as provided by ST does not appear to have pre-built ...
