What are some common methods for calculating CPU utilization? I know one method is to add a count value in a while{} loop and use a timer. In the timer ISR, calculate the ratio of the count increment ...
Epson recommended a controller S1D13775BGA to us today. They said that their IC can support WVGA (800*480) screen. I wonder if any experts have done this?...
[size=4]CC13/26XX is TI's new generation of ultra-low power multi-protocol SOC processors that support Sub1G, 2.4G private protocols, BLE, Zigbee, RF4CE and 6LowPan. CC2640 is a BLE low-power Bluetoot...
When debugging STM32, I found a strange problem: the example program is as follows: uint8_t a,b,c; a = 0x80; b = 0x04; c = a>>4 + b>4; b = b<<4; c = a + b; In this way, the result of c is correct...
When you get a program, how should you import it and how should you learn from it? For example, the program above. I spent a long time on it, but after importing it, the compilation still fails. Maybe...
