Arduino spcr register - Direct Access to AVR Registers II Open Engeeknyers
SPDR and SPCR refer to SPIxCON register of the PIC32. My confusion came mostly due to a misconception on my part that the Arduino platform provided.
Arduino Reference. EEVBlog. SPI (Serial Peripheral Interface) The MSTR bit within the SPCR register tells the AVR whether it is a master or a slave.
May be it's better to formulate my question in a different way. We know that all SPI settings are determined by the Arduino SPI Control Register (SPCR).
Video embeddedThe SPI Control Register (SPCR) As is obvious from the name, this register controls the SPI. We will find the bits that enable SPI, set up clock speed.
24 bit analogue to digital converter chip and arduino help. I am using a ads1256 adc and a arduino and the arduino IDE also clear control register clrSPCR.
ADC registers setup using spi communication. I have to use the communication register to select which register I want to configure. SPCR 0x5A; mode# 2.
