Posted on January 31, 2012 at 06:01I'm using the SPI TXE interrupt. My ISR simply checks to see if there is anything more to transmit in the buffer. If there is, it sends it, moves the buffer pointer, and returns. If there isn't anything left to ...
Posted on January 29, 2012 at 22:03Hi I'm a new STM32 user . I'm wondering how to send data from the computer to the stm boardusing the RS232 cable .
Posted on January 31, 2012 at 17:58Hi, I invested already complete afternoon, but I cannot come further, perhaps somebody could give me a hint? I need to read data from a parallel bus (16 bit wide) with a reduced frequency of typically 1-5MHz (shoul...
Posted on January 31, 2012 at 21:46In Ref Manual DMA configuration, many register bits have the condition: ''can be written only if EN=0''. This is ok from my side. But the last two bits in the list, FTH (Fifo Threshold), have the condition: ''can b...

Posted on January 24, 2012 at 17:15Hi All, I would like to use DMA to service a UART that I am implementing (RX and TX). My project has 2 bi-directional data ports (including the UART) which have different data rates (up to 512kbps). I have to use h...

Posted on January 27, 2012 at 13:11I can't find any info about the capability of the DAC output buffer of being a current sink. Is it possible? Which is the max sink current? EDIT: I mean the DAC integrated on the uC chip and connected to GPIO pins,...
Posted on January 29, 2012 at 21:48Hi, I have a clock signal in the range of 10MHz. In every clock cycle (100nsec long) I would like to create a strobe signal, typically 20nsec long, and exact point of the strobe should be variable. My Clock is pro...
