Posted on October 12, 2017 at 18:01Hi everybody,I made my PCBA with a STM32l151CC and a SX1272 from Semtech in order to make a LoRa Accessory.I use Cube MX software to configure all the peripheral of my accessory (SPI, ADC, RTC, etc.) and I add all ...
Posted on October 11, 2017 at 02:30I am working on a problem with DSP Concepts. I have an STM32F4 Discovery MB997B and they have an STM32F407 Discovery MB997C-01.They have modified their code that runs on the STM32F4 Discovery module and provided th...
Posted on October 11, 2017 at 16:13Hi,We are using STM32F479 processor in our design. We want to calculate the CPU load using Ulink Pro. We are unable to get the performance analysis using ulink pro when the system clock is 168MHz (system_stm32f4xx....
Posted on October 12, 2017 at 18:26I am using Keil_MDK V5.23 and trying to read/write SD card on STM32F769NI Discovery board.So far,1. I created project in Keil MDK for STM32F769NI and selected necessary options from Manage Run Time Environment.2. I...
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.
