The system is reset asynchronously. When the reset signal is valid, all values in the RAM must be cleared to zero. Before the reset signal ends, the RAM must be reset. How should such an initializatio...
I am working on a dot matrix screen display system recently. I want to display it by calling the font library. I don't know how to transplant the Chinese dot matrix font library to STM32....
1. It must be a host driver 2. I have seen the following NXP LPC 24XX series, which are analog devices, and they do not match the device data processed by our mission development board. Leave my conta...
J-Link not only supports the burning of the Flash on the MCU , but also can directly burn the SPI Flash through the SPI protocol. Because the SPI protocol is used , even if the MCU connected to the SP...
We want to use an active crystal oscillator to generate a 4MHz square wave, then pass it through a low-pass filter to generate a sine wave, and then use the power amplifier circuit to resonate and rad...
