I would like to ask you, when BLUENRG-1 is used as a slave, due to power consumption issues, the slave needs to sleep. Can you tell me how to actively disconnect the slave when it is connected?...
Is the WiFi frequency hopping completed by software protocol operation or does the WiFi module change the channel and transmission power according to the external environment?...
I found a strange phenomenon. When using STM8's TIM1 to generate PWM, there are problems at two specific points when updating TIM1_CCR. It can't be updated. It probably occurs when TIM1_CCR=230 and TI...
As the title says, I use the SIGNUM emulator ADM51 and develop with the keil c51 software. Currently, I cannot use keil for simulation and debugging. It is very inconvenient to use Wemu51 for debuggin...
