WebJan 1, 2024 · Let say you want ti acquire data from adc from 3-channel in continuous mode. Since each conversion requires 15 cycles for 12-bit since the adc clock is the core frequency over (16MHz/2=8MHz), thats means generating interrupts at rate near half mega hertz which will effect the performance of the mcu. Hence, using DMA in such case makes sense. 3. WebJun 3, 2024 · Software. As I explained in Part 1, I implemented the CHIP-8 emulation logic as a backend library independent of how the input and output is handled.In particular, the chip8 library exposes a struct which maintains the state of the CHIP-8 virtual machine and a method that is supposed to be called 60 times per second called frame, among other …

CRH is used to set type/and or speed of pins 8-15 of the port. CRL is used to set type/and or speed of pins 0-7 of the port. Accessed as a 32 bit word, with 4 bits representing the state of each pin. Out of these 4 bits, the low 2 bits are MODE, and high 2 bits are CNF.
