Posted on July 26, 2017 at 12:15Hi,When i checked on DSO (scope) i found that after chip select SPI_NSS latch to ground.there in clock signals on clk pin.there is no data on SI and SO pin.Why there no data on SPI's Pin?Why SPI_NSS latch to ground?...
Posted on July 27, 2017 at 07:33i have purchased a stm3210c Eval board , want to establish ethernet connection but unable to do itpls tell me the solution , and suggest how to transmit data from microcontroller to PC via ethernet
Posted on August 01, 2017 at 04:08First, I introduce the background simply. I have program the STM32F072RB for somedays. I do this project start with STM32CubeMX. It�s going well until now. I have using the 2 DMA for SPI transmit before. And I want ...
Posted on July 10, 2017 at 07:49HelloI want to generate a 50Hz stable sine wave which I will amplify in order to obtain AC and DC voltage and current.The strategy is to generate the sine wave using DAC or PWM. I used one STM32 MCU with two DAC outpu...

Posted on July 19, 2017 at 16:05Hello everybody,I have some trouble when I want to erase my chip by sector erase or mass erase (ST LINK UTILITY with ST LINK dongle) I obtain some dummy bytes after an erase operation like that :00 00 00 00 00 0...
Posted on August 01, 2017 at 10:32Hello,I am searching for an STM32 device which offers 3 full 12-bit analog watchdogs.I have spent hours navigating on st.com but all I have found was the STMF303 line with 1x 12-bit watchdog + 2x 8-bit watchdogs.Can...
Posted on July 31, 2017 at 13:55Hey I use stm32f030p4 and i want counting a external frequency (Learning remote ).I configure timer and interrupts like thisTIM_ICInitStructure.TIM_Channel = TIM_Channel_1;TIM_ICInitStructure.TIM_ICPolarity = TIM_ICP...
Posted on August 01, 2017 at 10:45Hi,I have an 8GB eMMC memory and when I read the capacity I can obtain (2097152*512)/(1024*1024*1024) = 1 GBWhat is the limitation of HAL library about the size of an eMMC ? How I can bypass this issue ?After some ...
Posted on August 01, 2017 at 10:25Hello! I am trying to generate a triangular wave of frequency 8kHz using DAC and DMA. DAC is triggered using a timer so that the DAC speed will be 1 MSPS. I am working on stm32L476 discovery board. I am using stm32C...
