Posted on January 10, 2014 at 17:10Hello. I am looking at https://github.com/mabl/ChibiOS/blob/master/os/ports/GCC/ARMCMx/STM32F4xx/ld/STM32F405xG.ld, one of the GNU linker scripts for the ChibiOS project. I understand this script for the most pa...
Posted on January 12, 2014 at 05:14Dear All,We are designing a new product with some specifics needs :- camera interface to a OV2643 sensor- SPI to a CC3000 from TI for streaming MJPEG over Wifi, and doing some other socket light communications- 2 U...
Posted on January 14, 2014 at 05:48Hi all I need to make an I2S 192Khz/ 24 Bits and purpose use STM32F103. I read STM32F103 data sheet (RM0008) , they said that STM32F103 not support I2S 192Khz. But in this datasheet, i also see in page (704/1096):...
Posted on January 14, 2014 at 00:52 I am new to ARM and have been figuring out ways to set interrupts for certain peripherals that I have hooked to my board; however, I am having trouble understanding how to set up the vector interrupt table so i...
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 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...
