Posted on October 12, 2017 at 15:02HiThere is no RD pin on the lcd.there are only WR, RS, CS and 16 bit data bus.RD pin (FSMC_NOE) required? Thank you.void LCD_CtrlLinesConfig(void){ GPIO_InitTypeDef GPIO_InitStructure;/* Enable GPIOD, GPIOE, GPIOF...
Posted on October 12, 2017 at 14:51Hi,I am trying to sync two three phase center aligned PWM signals on my STM32F446.Goal is to habe the center of the two PWM signals to be offset by half of the base frequency.Is this possbile and if yes how do I co...
Posted on October 12, 2017 at 17:10Ok, quick background first. I am using RTC ALARMB to have a timeout queue that survives STOP mode (which SYSTICK does not).My PREDIV_S is 2048, PREDIV_A is 16 in case this matters.The code that I am using can run i...
Posted on October 12, 2017 at 10:04Hi,trying to transmit data via USART1 of STM32L476 Nucleo evaluation board. Use PA9 for TxD.Character count is 254*2+14 = 522 or 255*2+14 = 524.522 always is ok, 524 gives errors at receiver site.Data switches b...
Posted on October 12, 2017 at 16:30Not a question, but an observation. I am using the STM32L476G-EVAL board with STM32Cube_FW_L4_V1.9.0 and noted that within the call to HAL_SPI_TransmitReceive_DMA(), if calls to HAL_DMA_Start_IT() do not succeed fo...
Posted on February 27, 2017 at 12:09Hello,even so e.g. OPTCR1 seems to to be used on STM32F401, system headers define values with OPTCR1. This pollutes the headers.
