Posted on March 21, 2013 at 19:21 I am using an STM32F4, and I'm having difficulty getting SPI to transmit using DMA. If I manually write to the SPI data register, I see the appropriate activity on the logic analyzer, but if I use DMA to initiat...
Posted on January 27, 2014 at 11:46Hey at all, First of all I want to say that my english isn't the best. I have got a new project to do it on a STM32F405 controller. I must measure two frequencies: 1. f1 = 13 to 16MHz 2. f2 = 10 to 13MHz my plan to...
Posted on February 10, 2014 at 16:27hi, i have 3 EVALST7590T-2, I would like to know if the boards are set as the default service node or as a base node and how to do and where to get the files to set them as a base node or service node. Thank you ...
Posted on February 09, 2014 at 16:40Hi, in my project a 2.8V voltage regulator is connected to the VDD pins of the STM32Fxx device. VBat is directly connected to a 3V battery. After reset the mcu processes some tasks and after that the controller f...
Posted on February 01, 2013 at 16:03I'm trying to read the SD CARD Configuration Register (SCR) on an SD memory card using the SDIO peripheral and I'm not sure if I'm approaching this in the right way, so I'm hoping someone here may have some experi...
Posted on February 07, 2014 at 00:02I'm using a DMA for the first time (on a STM32F427), and am having a bit of trouble: I don't see SCK on any of my four SPIs when trying to transfer data via the DMA (specifically, I've only tried on the Tx side so...

Posted on February 07, 2014 at 11:15DearI saw STM32F429 discovery board is MF supported. And I looked up the all functions, and it is not include Ethernet. But, only binary image files are offered on the web site. Is there any way of getting porting...
Posted on January 29, 2014 at 10:33hallo, to program the STM32 microcontroller of my EVALST7590T-2 as base node or service node i can use the STMLINK and if i must to connect on STM32 UART SERVICE or on STM32 SWD ? And then what must i do? thanks. S...
Posted on February 07, 2014 at 15:23Hi,I am trying to use two USARTs at the same time, but I can't get it to work.First:void RCC_Configuration(void){ /* USART1 clock enable */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE); /* USART2 clock...
