- Sending a 16 bit message (SPI) - Arduino Forum
Operate the DAC at a SCK rate less than 5 MHz as the 5 MHz (as per data sheet) spec is the design value and not a tested value I would recommend 125 kbit sec (125000)
- Basics of SPI: Serial Communications - Texas Instruments
Common Timing A serial clock is used to determine a common timing: Serial Clock from the controller
- Proper way to send 16 bit SPI data - STMicroelectronics
If I config for 16bit, it will send 8 bits of data in a 16bit clock length and throw away the 2nd byte that I tell it to send If I use 8bit, the device I am using works fine for 8bit register writes and reads
- c - STM32 HAL SPI 16 bit Transmit - Stack Overflow
I have just had a look at the HAL code, and it looks like the size is the number of words So it seems that you are right, it should be 2 (to send 2 16-bit words)
- SPI and framed SPI - Electrical Engineering Stack Exchange
Here are the details of how normal SPI and framed SPI are implemented on a PIC32 "In Normal mode operation, the SPI Master controls the generation of the serial clock The number of output clock pulses corresponds to the transfer data width: 8, 16, or 32 bits "
- STM32 SPI Tutorial - HAL Code Examples - Interrupt DMA - DeepBlue
Each data frame is 8 or 16 bits long depending on the size of the data programmed using the DFF bit in the SPI_CR1 register The selected data frame format is applicable for transmission and or reception
- SPI. transfer() | Arduino Documentation
SPI transfer is based on a simultaneous send and receive: the received data is returned in receivedVal (or receivedVal16) In case of buffer transfers the received data is stored in the buffer in-place (the old data is replaced with the data received)
- Understanding SPI. transfer (buf, size) - Arduino Forum
Hello, currently I'm playing around with a 32bit shift registers and found the idea of shifting all 32bits at once intriguing (its not a chain, but one chip), therefore I started playing around with the SPI transfer (buf, size) method which in principle can transfer arbitrarily long patterns
