WebSep 30, 2024 · Sep 30, 2024 at 9:36 I believe the data is out of sync given how I call TransmitReceive (). I debugged master and all the entire rx array is filled with 255 in all 9 positions. I can't debug the slave as the debugger won't support two devices being connected. The slave pulls power from the master board in my current config. – … Webbool spiTransfer (SPI_TypeDef *instance, uint8_t *out, const uint8_t *in, int len) { SPIDevice device = spiDeviceByInstance (instance); HAL_StatusTypeDef status; #define SPI_DEFAULT_TIMEOUT 10 if (!out) // Tx only { status = HAL_SPI_Transmit (&spiHardwareMap [device].hspi, (uint8_t *)in, len, SPI_DEFAULT_TIMEOUT); } else if …
Timeout error in Quad SPI - Electrical Engineering Stack Exchange
WebThe SPI supports master and slave mode : (#) There are two modes of transfer: (++) Blocking mode: The communication is performed in polling mode. The HAL status of all data processing is returned by the same function. after finishing transfer. (++) No-Blocking mode: The communication is performed using Interrupts. WebWhat exactly is throttling the SPI transfers? If you're using DMA directly (rather than triggered by a timer or something else), then as soon as the SPI is free, the DMA peripheral would start another transfer. As a result, being busy all the time would be expected. how many km is mount everest
