Hello everyone, I am working on a project about PWM input capture recently. The microcontroller used is STM8S105. I am using the input capture function of STM8 to use the library function TIME1 CH1 to...
1. Principle 1. Infrared emission protocol The infrared transmission protocol has been written in the previous article , so I will not repeat it here. 2. Timer counting and input capture A timer...[Details]
1. Purpose Since the number of times the STM32 FLASH can be erased and written is limited, in order to protect our FLASH and extend the use time of the MCU, we can debug on the SRAM. SRAM is a ...[Details]
In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]
In 1952, Bell Labs built a 6-foot-tall automatic number recognition machine called "Audrey", which could recognize the pronunciation of the numbers 0 to 9 with an accuracy of more than 90%. And its...[Details]
