Posted on June 27, 2017 at 15:02Hi.I'm trying to use DMA to drive PWM output for led effects. MCU write seems to be OK, however there's few very weird consepts related to DMA configuration I don't seem to be able to wrap my head around.void HAL_TIM...
Posted on June 28, 2017 at 03:19Dear allUseing CAN1 of STM32F205, 32-bit Mask Mode filter, filter bank 0-13 work all right for now. Then I am trying to configurate CAN2SB = 28d, for letting CAN1 use all 28 filter banks.But it doesn't work, here is m...
Posted on June 26, 2017 at 01:13I am experiencing some issues with the ADC on my L0. I configure it with PCLK as the input clock in CKMODE, start it up, and take a sample. Everything works fine. I then decide to set the oversampling mode (which is i...
Posted on June 24, 2017 at 23:53I use a debugger of ST-Link and STM32 ST-Link Utility, I try to read 128K of the microcontroller flash-memory from the address 0x08020000. But STM32 ST-Link Utility reads only to the address 0x0802E000 - further the u...
Posted on June 28, 2017 at 13:39Hi, every one.I am trying to get data from IrDA SIR mode on STM32F092.I setup that USART Port 2 is sending IrDA packet and USART Port 1 is receiving ( it similar to loop-back, wired USART2 TX and USART RX )I can see t...
Posted on June 28, 2017 at 13:21Hi everyoneI'm usging STM32F103VE @72MhzI wonder how fast can I counter using external interrupt?These days I try to count clock signal by EXTI. ( clock signal is 10 Mhz) Is it possible?If impossible then, what is lim...
Posted on June 28, 2017 at 13:47hi i am new to stm32. i have purchased stm32vl discovery board recently. i would like to interface 2 UARTS ,2 spi and one i2c peripherals together with the board .how can i do it using interrupts can any one help me o...
Posted on June 16, 2017 at 12:01And also configure the Rx FIFO Threshold to 1/4 (i.e. 8-bit) so it generates the RXNE on byte reception.
Posted on June 26, 2017 at 04:04I plug in my CubeMX generated USB CDC class implementation into a PC host and CDC_Init_FS gets called as expectedWhen I unplug, I expect that CDC_DeInit_FS be called so I can take the link down but it doesn't.When I p...
Posted on June 26, 2017 at 15:39Hi,STM32F446 user here. I'm routing RTC alarm output to PC13 and after an alarm I need to clear the output pin back to low state. I recall myself reading something about clearing RTC alarm output in a specific way but...
