YC development board handwriting development, I need to implement the full-screen handwriting function. The method I got so far is to write a touch screen driver by myself. Because the system itself h
Is anyone using the STM32L152 series MCU? I want to ask a question. I want to do low power consumption now, so I need to enter Stop mode. But I read a book and it says that entering Stop mode will tur
c=sizeof(USB_CONFIGURATION_DESCRIPTOR) + sizeof(USB_INTERFACE_DESCRIPTOR) + (NUM_ENDPOINTS * sizeof(USB_ENDPOINT_DESCRIPTOR));If you write it like this on the IAR compiler, an error will be reported.
I tried the Ethernet upgrade code provided by everyone in the forum, but it failed to test. Which boss can provide a simple bootloader test code for the Ethernet upgrade program? Thank you!
The key to the oscillator IIBLC meter is the oscillation circuit shown in Figure 1. LM311 is a voltage comparator. When the power is applied, the second pin of LM311 is 2.5V due to the voltage divider
Phase shifter is a regulating is widely used in signal processing and instrument measurement. In the past, phase shifters were generally composed of a 12-sided phase shift circuit with three-phase inp
