Now I am going to make a fatfs+ARM+ucos data collection system. The collected data will be saved in files with year, month and day as the file name. The historical records can be checked on the LCD di...
The code in the attachment has been transplanted and run on MSP430F247. It is a very simple project.The basic work is to create two tasks and then schedule the two tasks....
Friends who have stm32f7 boards can download the program STM32Cube_FW_F7_V1.1.0\Project\STM32746G-Discovery\[/size] [size=6]Applications\QSPI\QSPI_perfs if you have time. I found that the data read fr...
Can anyone give me an example of sending MMS using GPRS modem? Written in C++, I'd be grateful. It includes connecting to the network and sending MMS. If you can solve this problem, I'd give you 1000 ...
I used a potentiometer to get a voltage through resistor voltage division and connected it to the analog input port. I found that when adjusting the potentiometer, the voltage did not change evenly an...
I just saw a netizen share an IoT design in our forum. I'd like to share it with you to provide you with some ideas. Welcome everyone to participate in the IoT Creative Design Competition in cooperati...
