Posted on September 16, 2017 at 02:34I need a timer that is accurate to 1us for a project I am working on. I bought some stm32f051 discovery boards to get going. I noticed all the timers seemed to be slow by about 0.75% (I checked them with a scope)...
Posted on August 29, 2017 at 17:48Hi!I have some very sporadic resets that are proving troublesome to debug. I'm using an STM32L083Based on the RCC_CSR there's an IWDG reset. The IWDG is definitely enabled (total time of 28s) and being cleared often...
Posted on September 17, 2017 at 17:46Hi,The HAL_NAND_MspInit() is not generated in the stm32f4xx_hal_msp.c when the attached .ioc is used. Therefore the NAND pins are not driven by the MCU and NAND driver is not working at all. How can I enable gene...
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...
