Hi, I am new to ARM development and will be using LPC1112 (Cortex-M0) to make a simple wav audio player. I know there is a SSP which can operate in SPI mode, but hopefully it can be used in TI SSI mode to interface with an I2S codec. The SPI is used to interface a SD card. How can I bit bang SPI on ARM? I couldn't find SPI bit bang code specifically for ARM/LPC111x. It is simply using bit bang code for AVR/8051/etc? Thanks in advance, John
As BitBanging is a software emulation of hardware, the code for AVR should also work on ARM. An adaption to the outpin pins is required, of course ;)
I see. Thanks Nippey!
