I am an embedded novice but know my way around linux, so I used the below code on an Rpi3 to connect to the chip and read the version from the REG_VERSION register at address 0x42 and was able to get the correct value of 0x12.. int main() { ...
WebTimers are typically 8, 16 or 32 bits, making it easy to read and write them using standard 8, 16 or 32 bit variables. It is not unusual to find timers of different sizes on the same microcontroller. For example, most AVRs have both 8-bit and 16-bit timers, and some NXP Cortex M3 parts have both 16-bit and 32-bit timers. WebAs you can see above, the 0th bit of RCC_AHB1ENR Register enables the clock for the GPIOA. That’s why we need to write a 1 in the 0th position. RCC->AHB1ENR = (1<<0); …
