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...
Posted on January 03, 2012 at 09:29Hi everybody, i work with the evalboard STM3220G with the USB example from the USB host-device lib. I try to write additional data in the create/existing file, but I'm not successful. Can anyone say me, what i must...
Posted on January 28, 2012 at 23:22In the STM32F4 I found some minor errors in the timer descriptions: - Page 395 - Description SMCR-TS for Timer 2...5: Should refer to Table 62, not 60 (Table 60 is referred at some points in the manual, but it does...
Posted on January 27, 2012 at 10:28Hi, in the reference manual RM0090 for STMF4, in chapter 7.1 it is recommended to activate the ''IO compensation cell'' (Register SYSCFG_CMPCR), if outputs are used with speed settings of 50 or 100 MHz (GPIOx_OSPEE...
Posted on January 27, 2012 at 11:54In Ref. Manual 6.4.11 Table 18, for the registers GPIOx_OTYPER a reset value of 0x4444 is specified, but I think this is an error - should be 0x0000? (as specified in 6.4.2 at the register description?).
