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 31, 2012 at 19:46Hello,I have a hard fault when running my code, and the result of the hard fault is :[Hard Fault Handler] R0 = 4000000 R1 = 1 R2 = 20003fe0 R3 = 40013c00 R12 = 0 LR = 8014acd PC = 8019474 PSR = 100022c BFAR= ...

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...
Posted on January 29, 2012 at 16:18Hi, I just discovered, that unfortunately it is NOT possible, to use CAN2 together with USB-HS in the STM32F4 or STM32F2 device. CAN2-RX is available only on pins PB5 or PB12. But if Hi-Speed USB is used (ULPI inte...
Posted on January 26, 2012 at 10:28I need a delay in a timer 4 interrupt. To realize this I wrote the the follow lines:if(TIM_GetITStatus(TIM4, TIM_IT_CC1) == SET) { TIM_ClearITPendingBit(TIM4, TIM_IT_CC1); TIM_ClearFlag(TIM4, TIM_FLAG_CC3); while(T...
