Hi, I observed a limitation in the STM32H7 reference manual saying that "The current version of the SDMMC supports only one SD/SDIO/e•MMC card at any onetime and a stack of e•MMC."So my application requires to control two SDIO slaves from both SDIO i...
I want to use IWDG with stm32f103rct6 chip with ll library. such samples code as below:```static int iwdg_init (unsigned short int expired_ms){/* 开启 LSI, IWDG */ __HAL_RCC_LSI_ENABLE(); LL_RCC_LSI_Enable(); while (!LL_RCC_LSI_IsReady()); LL_IWDG_Enab...
Hi everyone,I am using the NUCLEO STM32-F401RE V dev board and trying to communicate with an MAX31856 temperature amplifier. I am using SPI2 peripheral. I am able to write values on the SPI line. I have printed them out to the UART and have verified ...
HiI am receiving data from a 24-bit ADC through SPI. To reduce frequency of SPI-SCK, the ADC has the capability to send data through 2 SPI-MISO to STM32f107, both of them working with a single SPI-SCK (18Mbit/s). How can I configure SPIs in STM32cube...
HI there, I have rewitten this simple piece of code from scratch multiple times with no success. I am just attempting to turn on a set of LEDs. First in the While Loop. Second in the interupt handler for TIM2. The chip is a STM32F411CCU in a homes...
Hi,I am working on SPI communication between STM32G491 and ATM90E26. and I am using the SPI polling API with HAL_SPI_Transmit and HAL_SPI_Receive.My System clock is 96Mhz and I am using prescaler of 64 for SPI.CLKPolarity=Low,CLKPhase=1Edge.Communica...
I have a HAL_SPI_TransmitReceive_DMA() transaction that I am performing. The data can be seen on the line to properly get clocked out over SPI. The problem is that in the receive interrupt, we kick off the next transaction (a DMA SPI write). This wri...
I need to assign 8 GPIOs (4 I/p + 4 o/p) for membrane keypad pushbutton circuit. I am worried about ESD protection of GPIOs. Please suggest STM parts for ESD protection best suited for use purpose.Kindly let know if I can select any pins or there ...
I have spent a few weeks reviewing HAL related and LL related neopixel libs however I would love if there was someone who had a working version of literally just the ability to set up a neopixel on any port and simply light it or light a few neopixel...
Need to use stm32f407vgt6 discovery board to connect with HID card reader via USB OTG.Now I was using stm32 to read keyboard input successfully but I think the HID card reader works the same with the keyboard so I was using the same code but nothing ...
