Posted on March 12, 2013 at 12:39Hello, I'm using the STM32F4 discovery and I need to control the state of a MOSFET to enable a relè. Precisely if the USART1 receives a particular comand a pin has to generate a high tension level to set the MOSFET ...
Posted on March 13, 2013 at 06:39Hi all.I am having a really hard time finding any documentation at all on how to interface with a PCCARD bus using the FSMC.I am specifically looking for how to do I/O space access.Also, about some possible issue wit...
Posted on March 06, 2013 at 20:16Hi, I just bought STM32W RF Control Kit, and I can't seem to find the SimpleMAC package for download. I followed the link but it redirects me to the order page for the Control Kit. It says of the instructions that I...
Posted on March 12, 2013 at 21:14Is there any way to discover if we are running inside any ISR (uart, systick, timers, etc.)? It would avoid dead-locks.I thought reading IPSR would help, so if ISR_NUMBER is different from 0 (thread mode), then we wo...
Posted on March 12, 2013 at 12:47 hi! I've built my simple application reading two analog input using a single adc and transferring all into memory with dma. Anyway the code not always works. Sometimes I get consistent readings, some others I...
Posted on March 12, 2013 at 09:24Hi Programmers, I Would like to ask if you have links for GOOD tutorials for STM32f4 Discovery / STM32-E4(Olimex) Basic UDP as client and as server for arm Basic TCP as client and as server for arm I am bleeding wit...
Posted on May 29, 2011 at 08:21Hi, I find there is no applictation note about how to use IEEE1588 on stm32f107. As a newbie, it is very hard to start. When i enabled the timestamp function, and adjusted the ethernet receive processing, but the ether...
Posted on March 11, 2013 at 21:55Hi All,I need to create a library for a project using the STM32F4. I have tried using both CoIDE and GCC command line tools. No luck at all, I ended up in Default_Handler() when the library function was called. Creat...
Posted on March 10, 2013 at 09:42Hi all, I am very new to ARM chips, lots to learn. I have some code from a ST example that initialises the gpio/tim2/DAC2/DMA all in one funtion it works fine. If I split it onto 4 functions for clarity etc, it stops...
Posted on March 11, 2013 at 14:13Hi We figured out some ADC channel miss match on STM32F100C8 device, which we couldn't explane. We use the following test setup: - ADC1_IN0 (PA0) to ADC1_IN3 (PA3) are used. - Regular group scan mode with DMA is used...
