Posted on December 03, 2013 at 19:56Hello,I've succesfully started programming a STM32F0Discoveryboard: MCU is running on HSI (8MHz) at runmode.MCU is going into/outof stopmode every 5 seconds using the RTC running on LSE (32.768kHz)USART1 is conn...
Posted on December 03, 2013 at 21:45 Hello I found an example of using DMA with UART on STM32F407 on this thread UART with DMA mode but i can't make it work. I use a STM32F4-Discovery and i try to see if DMA1_Stream2_IRQHandler is called...
Posted on December 03, 2013 at 09:26Hi. I want to know that there are any MCU which support 9 bit SPI interface. Do you know that? I will wait for your answer. Thanks.
Posted on December 02, 2013 at 23:38I am recently working on lwIP. I have a STM3210C eval board. I installed pragram codes. And I connected my board to modem using Cat5e ethernet cable. LCD is working, I think, that shows program is properly instal...
Posted on December 03, 2013 at 22:32 Hello Guys, I am trying to make the RTC timestamp feature works but I couldn't. I have to detect a tamper event during anytime, even if the MCU is turned off, for this reason I have connected a batter...
Posted on November 25, 2013 at 16:08 Hi everyone, I am trying to implement the SPI1 by hardware in my STM32F407VGT6, I did everything and actually it seems to work. But I was trying to read the ID from my SPI device (which is a Flash ...
Posted on December 03, 2013 at 17:51 Hi everyone, I am trying to figure out how make work the RTC timestamp feature when this peripheral is supplied by VBAT and when a Tamper detection occurs. And be sure about my RTC configuration...
