I'm still a newbie. I have some ideas about measuring resistance and capacitance, but I'm not sure whether it's feasible. I'd like to ask for advice and criticism. Resistance measurement method: The s...
The working temperature of the thermocouple is relatively high, about 800 degrees; the site conditions are bad, with strong wind and sand. Thank you...
I have just come across the concept of HPS of DE1_SOC. Now I want to release UART_TX and UART_RX bound to HPS and use them directly as inputs to FPGA with as little effort as possible. All previous at...
I have a question for you. I'm debugging a small system of a single-chip microcomputer recently, and I encountered such a problem: [color=Red][b]After the board is powered on, it is sometimes normal, ...
Finally, I started to learn F4. Today, I downloaded the information and prepared to start learning. Unexpectedly, my compilation environment version is too low and does not support F429. My IAR is als...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
