Posted on February 03, 2014 at 15:58Hullo guys , ....... from the memory map on STM32F2XX datasheet , each GPIO takes 1024 bytes space from memory , I wonder why? ........ each GPIO has 10 32-bit registers , does not that means 40 bytes per GPIO ? ....
Posted on February 03, 2014 at 15:46Is there any restrictions to set different CAN bitrate for CAN1 and CAN2? Some microcontrollers only supports the same baudrate for two separate channels.Linas
Posted on January 31, 2014 at 22:59Hello, I have a question on the usb cdc. Is there any possible to use the same USB port to work as cdc host and cdc device? I have board with one USB port and the board need to tell what the equipment is connected ...
Posted on January 31, 2014 at 16:56I'm planning to use some of new STM32L100 most probably in one of RB or R6 version mcu in upcoming project. 1) Does anybody know, when will ST release errata notes to those versions (there is only errata pdf for R...
Posted on January 31, 2014 at 14:45Hi I have following question: On the datasheet page 113 there is a note for calculate the ENOB: ENOB = SINAD / 6.02 - 0.292 Now I'm wondering because the right formula is ENOB = SINAD - 1.76dB / 6.02 !!! Why do you...
Posted on February 02, 2014 at 18:20 I have read the ST Flash programming manual and looked at the ST examples. I am using STM32F103VC. I wrote some code to initialize and write/read from flash memory. This is just a test, but I end up in th...
Posted on February 02, 2014 at 23:56Please provide guidance: I am attempting to configure i2c on STM32F0308-Discovery Like to use PIN 46/47 as PF6/PF7 i2c1_SCL and i2c1_SDA/* FROM DISCOVERY Driver Enable peripheral clock using RCC_APB1PeriphClockCmd...
Posted on October 20, 2013 at 22:19Hello, Is this tool already available for 429/439 series STM32 ? If it is, where can I find it ? Thomas.
Posted on February 02, 2014 at 11:45 I'm using the below code to activate output pins. void GPIO_cfg( void ){ GPIO_InitTypeDef GPIO_IS; // GPIO Initialisation Structure => GPIO_IS // Configure/enable peripheral clocks RCC_AHBP...
Posted on February 02, 2014 at 10:50Hello, my input capture code TIM1_CH3 (PA10) works very well on an F100 or F103, but not on the STM32F051. If i submit the debug session of the test code the GPIO and TIM1 register looks like ok. It looks like an ...
