Posted on November 02, 2012 at 18:18I am having difficulty compiling the Demonstration Builder example code. I am using MDK-ARM (Keil) with the 256k license but the code is 265k when linked. I read the app note to disable modules but when I tried ...
Posted on November 02, 2012 at 14:51Hello guys, I have been messing with interrupts recently and I have hard time to find in the manuals how the priorities actually work. I have seen the priority groups and priority values. If I understood it proper...
Posted on November 02, 2012 at 07:54I need some help setting up I2C connection to LIS302DL or a generic I2C accelerometer. I need some code examples to get the accelerometer working. Thanks in advance.
Posted on November 01, 2012 at 18:35I have a peripheral bursting 8-bit parallel data at 56MHz gated by a data valid signal. Can the STM32F4xx support peripheral to memory dma at this rate? What is the max rate the STM32F4 can handle dma requests? ...
Posted on November 01, 2012 at 20:17Hello, I am trying to attach external PHY chip to my STM32F4Discovery board. I am using the 'stm32f4x7_eth_lwip' example from the ST site. I think for people that have the bigger evaluation board with already sold...
Posted on November 01, 2012 at 17:29So does the whole family of STM32M0-STM32M4 have their own StdPeriphDriver offering? Under the advisement of my hardware guide, I am trying to test out the Freescale Freedom board after I have developed on the ST...
Posted on November 01, 2012 at 07:44Dear all, MCU we are using is STM32 F103CBT6, on a motor driver application. Wehave encountered a strange phenomenon that Bus Fault occurred randomly duringnormal operation, and the fault message shows that the PC...
Posted on October 31, 2012 at 08:05I emulate an I2C eeprom. I first receive the address, then I set the DMA-Source pointer to my tx-array (DMA_MemoryBaseAddr). As I have configured autoincrement, several bytes will be transferred. When the second re...
