The overall idea of the project is to use the GD32E231 development board as the main control unit, use the LCD5110 display screen and two user buttons as the human-computer interaction module, use the infrared probe for monitoring, and use the AT24C02flash chip to save and record the triggering time of the monitoring alarm, so that Initial implementation of basic intelligent functions.
The i.MX RT1060 EVK is an evaluation kit for the i.MX RT1060 crossover processor, which uses NXP's advanced Arm Cortex-M7 core implementation.
Increase the number of clock source outputs using low-jitter LVPECL fanout buffers
Designers need open-drain logic to run at 1.8V at the 1-Wire master IO. Most 1-Wire slave devices cannot run at 1.8V. This application note presents an RD (reference design) of a circuit that translates from a 1.8V 1-Wire master to a 5V
The PTN5110 Type-C demo kit shows a fully functional USB PD connection between DFP and UFP. The motherboard and docking board can also be ordered separately.
PN7150 development kit for RaspberryPi, BeagleBone Black and boards with Arduino interface, including: LPCXpresso, Kinetis Freedom and i.MX boards.
2 kW three-phase motor control evaluation board with STGIPS20C60 IGBT smart power module
LED brightness dimming changes the brightness by changing the LED's on-time. The longer the LED's on-time per unit time, the higher the brightness. In practical applications, it is controlled by changing the duty cycle. It can be seen from the light efficiency conversion characteristics of LED that when the same duty cycle is increased, the brightness increases more at low gray values than at high gray values. At the same time, at low gray values, every time the gray value changes by one In small units, the value of the light intensity increase rate D is relatively large. As the brightness increases, the light intensity increase rate D decreases, and the human eye's sensitivity to light changes also decreases. That is to say, the level jump is very obvious at low brightness. The brightness jump is particularly sensitive to human vision and cannot achieve a flexible effect of gradually brightening or dimming. The principle of smooth dimming is to improve the dimming effect of LED by changing the linearity of LED dimming curve.
