This course teaches you step by step how to program in C on an embedded microcontroller, as well as the internal operation of the embedded processor. Execute code on a Cortex-M processor and see how it connects to the physical world.
I connected a USB device to my board (wince system). After the wince system started, the driver of this device can be loaded correctly. I want to reset this device now. How can I do it? I cut off VCC

First, the bandwidth. This is usually written on the probe, how many MHz. If the bandwidth of the probe is not enough, no matter how high the bandwidth of the oscilloscope is, it is useless, and it is
void delay(unsigned int x) //about 1.5us{ while(x) { x--; } } void init_1820(void) { DS18B20_SET; DS18B20_CRL; delay(400); //more than 480us DDRC|=(1
It seems that there is a problem with the timing:
