Here is a 555 timer simulation, the output is adjustable duty cycle (less than 50%), the previous simulation, but this simulation is wrong, who can guide me? ? ? ?...
Generally, we recommend that codes with high real-time requirements and codes related to FLASH initialization, such as interrupt programs, be run on RAM.
In the F2837xD/37xS/07x series chips, the Flas...
