Posted on September 18, 2017 at 17:58Hello, my problem is I need to acquire a waveform at high frequency (sampling frequency in the order 35 to 50 MHz carried out by fast external ADC). I would like to use an high performance STM32 microcontroller (...
Posted on September 18, 2017 at 16:31Hi community,i have following situation:PC <--- ETH or RS232 ----> STM32F107 < ----CAN---- > STM32F105 with external power moduleI want to parse the ascii message (example K01NC|200) to a smaller protocol what i ...
Posted on September 15, 2017 at 22:38Hi to allI am new in STM32 and keil (I used Atmel chips) and now I am getting familier with them.I made a project and I can send data to serial port with the following function :'HAL_UART_Transmit(&huart1,(uint8_...
Posted on September 11, 2017 at 21:20Can it work as USB device on 1.8V (VDD), with separate regulator for 3.3V on VDD_USB?How pulling of D+ over 1.5k to 3.3V is done (internaly maybe)? If there is other performance limitation regarding working on lo...
Posted on September 18, 2017 at 11:06Hi, Can I use stm32f407 for smartcard project ? I found prepared smartcard project for some EVAL boards and STM32L053 boards in st's website. I wonder that can stm32f407 be used instead of eval boards and l053 bo...
Posted on September 15, 2017 at 17:52Hi,I try to move some array in CCM on stm32f415.I modify the ld script with CCM_SRAM (rwx) : ORIGIN = 0x10000000, LENGTH = 64K .ccmram : { . = ALIGN(4); _sccmram = .; /* create a global symbol at ccmram start ...
Posted on September 16, 2017 at 12:33I'm not sure if I'm understanding the gain bandwidth correctly, but can I use OA1ZHA op amp for a signal with ADC sampling frequency of 2 kHz? or am I really limited to only 400 kHz based on maximum gain bandwidt...
Posted on September 18, 2017 at 02:59EX) ODR = 1 -> I/O Pin State = 0 ?It is True?If ODR = 1 then I / O port is also 1?Is it OutputControl Not Gate?
Posted on September 15, 2017 at 14:17Hallo everybody,i have a circuit board whitch is fitted with a STM32F429BIT.The Software use STemWin and LWIP (without RTOS) and works good.Now i has order the same circuit board with the pin compatible STM32F767...
Posted on January 09, 2017 at 15:00I have a custom board I have designed and want to develop on, and want to use the my 'stm32f0-discovery' board to program this custom board.using the SWD pins on CN4 of my stm32f0-discovery board, i can use 'STM32 ...
