Posted on February 08, 2012 at 20:30I am new to arm and designing a new prototype board with a STM32F417 and 2 NAND Flash chips. In the data sheet it says the HCLK can go to 168MHz BUT it also says that the FSMC maximum clock is 60MHz at 3.3V. Does...
Posted on February 08, 2012 at 20:49I have an application that needs 9 (yes, 9) serial ports. The STM32F103 I am using supports 5, so I am adding an external 16554 quad uart. As part of my testing before actually getting a board built, I am trying...
Posted on February 06, 2012 at 18:02I am trying to interface with an SPI port device which requires a 24bit transfer, I have successfully managed to achieve this using the example code and standard peripheral library but I am seeing gaps between byt...
Posted on February 07, 2012 at 07:36 Hello! I'm looking for information - how to initialize data (e.g. arrays, strucutures etc.) in flash memory. It isn't enough RAM memory for my programm. I'm using Atollic TrueSTUDIO®/STM32 Lite IDE. I think th...
Posted on February 02, 2012 at 12:20Here is a sample session showing some basic uses of SNMP for remote management of an STM32-based device. This session was run under uClinux on an STM322G-EVAL board with Emraft's STM-MEM add-on. (Refer to www.emcr...

Posted on February 01, 2012 at 15:17 Hi all , A simple question: I have an external ADC, and to get the values, I need to generate cyles to obtain the values. My SPI is configured as master + fullduplex mode and to receive bytes I have to send a dum...
Posted on February 03, 2012 at 21:20Hi, I am trying to get the SPI interface to work so that I can access the microSD card on the board. However I find that I cannot put the card into SPI mode, when sending CMD0 (go to idle) I read back 0, instead ...
Posted on January 31, 2012 at 13:25The problem is found, but there there is an eternal interrupt loop when NAK from device, so there is an another patch is required for the host lib, 'cause there is no wayto know when the device finished data transf...
Posted on January 30, 2012 at 08:06(I'm posting this ''again'' as it doesn't look like it posted. :-/)Hi,I've been using the PWM Output example for my PWM jobs. The timebase was setup as follows (with variables replaced with actual perimeters): Pre...
