I want to ask if it's possible to unload main routine form communications task and let them run in background.
For example I'm using on ARM MCU this peripherals:
When adc_start(ADC); is called, ADC start conversion in background so I don't need to wait untill ADC has finished conversion and I can go to the next istruction and later read the ADC result.
I want to ask if it's possible to do the same with communication periphericals. I2C and SPI can be fast, but since my MCU can reach 120Mhz of speed, it's a waste of MCU speed if I need to wait untill I2C have finished to trasmit at 400kHz or SPI at 20Mhz or worst with UART. Also, if I perform some tasks and I don't want to interrupt them, I need to be able to unload MCU from any interrupts form peripherals and let them recive packets, buffer them and when I need to read them.
For now I've used functions as "twi_master_write" that "will NOT return until all data has been written", I've looked and didn't found any functions to perform what I'm looking for.
Something like this is possible?
