When using an auto-coupling step-down transformer as a DC regulated power supply, when outputting +5V to power the system, it was found that the circuit breaker tripped when the transformer plug was p...
In standard mode, I want to set the I2C bus speed to 50kpbs/s. Which register should I modify? Is it IC_SS_SCL_HCNT? The manual says the minimum setting is 6. Does that mean it is 100kpbs/s? Thank you...
First of all, this is the first time I ported UCOS, and it is also the first time I use it. I only read some information before. I ported UCOS on the OPEN1081 development board and tested that it can ...
