I wrote and modified a program to use msp430g2553 to control nrf24l01. The following is the program of the receiving end. It has been tested and can be used. You can refer to it if you need it. #inclu...
I have found the formulas for ADC's sample-hold time and conversion time. Sample-hold time = 4×N×ADC12CLK. Conversion time = 13×(ADC12CLK/Fadc12clk). My question now is how to determine the values of ...
When I used STM8S207, I found that PD6 could enter interrupt normally, but PD7 could not. The settings were as follows:GPIO_Init(GPIOD, GPIO_PIN_7, GPIO_MODE_IN_PU_IT);I thought that the option byte n...
The manual of the EV1000 inverter I use was filed on 2008-08-05. Among its communication protocols - networking modes - single host and single slave, there is a method for the host PC to connect to th...
