SAVE MEMORY CONTENTS TO A FILE for STM32F3
Posted on January 29, 2014 at 17:00Hi all; I'm working with the discoveryF3 board, i'm using the ST-Link debugger. I want to save two float arrays into a file when debugging. My IDE is µVision4. I found that the command ''save'' can do that but ...
ADC1 STM32F0
Posted on January 30, 2014 at 03:56 Hi all, I just started working with STM32F0. I want to try ADC1 in this board but I find some trouble. I want to turn on the LED (PC8 and PC9) by using ADC asbenchmark, so when ADC1 reach 2000 bit or7D0...
strange spi signal problem
Posted on February 28, 2013 at 14:40Hello everyone, We are using STM32F215VGT on our project. When we send data over SPI from STM32F2, clock and data signals are not square wave. i attached clock signal. On our board, there is TXB0106 between STM32...
Does stm32 support DFU over serial (UART)?
Posted on February 04, 2014 at 03:30Hi all,I knew ST provides many examples for DFU over USB and I could successfully use the dfu-util tool to upload my binary code. I wonder if ST also support UART device firmware upgrade? Did anyone have experie...
Question about Address Boundary of STM32F2XX
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 ? ....
STM32F205 baudrate for separate CAN channels (CAN1 and CAN2)
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
One USB port work as cdc device and host
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 ...
STM32L100 - DFU bootloader from HSI & missing errata pdf
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...
STM32F3 SDADC ENOB
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...
