Hello,I have NUCLEO-STM32F429ZI kit and I want to operate the SPI as max speed. So, I design one simple example like make SPI1 as Slave and SPI4 as a master mode.This is worked for SPI_BAUDRATEPRESCALER_8 (11.25 MHz), SPI_BAUDRATEPRESCALER_16 (5.625 ...

I just started to working on STM8L162. I worked on STM32 SO, I searched the tool like STM32cube MX for STM8 and I got it. STM8CubeMX does not support the code generation yet. So , is there any other tool for STM8? From where I can download the driver...

HAL Library provide the HAL_Delay() for millisecond delay. I want to use micro second delay in STM32L4 so how I do it? Is it available in HAL library?

Hello Community members,As by enabling the DMA, I successfully communicate with SPI slave at 22.5 MHz. However, my requirement is to work at 45MHz.Here is my DMA settings: /* SPI1 DMA Init */ /* SPI1_RX Init */ hdma_spi1_rx.Instance = DMA2_...

Hello @berendi , After a few days, I have worked for this and as per your suggestion, I have read the SPI communication using DMA section in the reference manual.By implementing the same (DMA) in the firmware, I got the success.Thank you..!!!

Hello @berendi Thank you so much for your valuable feedback.In my existing code, I changed the polarity and phase (High/2edge - SPI MODE 3) and it is working. SPI4 is master send a data and SP1 slave is received that data (master is not receive any ...

Hello @berendi , Thank you so much for your suggestion.I tested with all three suggestion but it didn't worked.I changed the PA7 SPI1 MOSI pin to PB5. Instead of using the HAL driver, I used direct transmit/receive by DR. Can you please give some fu...

Yes, I already configured the GPIO at very High speed.Due to the WFH, I can't test on scope.I configured the NUCLEO-STM32F429ZI to 180 MHz clock and for SPI we can use (APB2 = 180/2) , SPI Clock = APBx / prescaler (45 MHz) as per prescaler setting.My...
