I started playing with it in 2009. It was very simple, with 2262 and 2272 wireless modules. It was the beginning of my experience with operating systems. Don’t throw bricks at me. Later, I wrote a few...
If the ARPE bit is turned off in STM32, the ARR value can be changed directly. Assuming that the current ARR value is relatively large, ARR=5000, when the timer interrupt is entered, the CNT counter h...
Yesterday, I was shopping in a supermarket and saw a customer buying more than 20 bags of salt. At first, I thought that person was running a small restaurant. This morning, when I went to work, I fou...
I'm a beginner in WinCE development and just built an eVC development environment. I installed the following components in order: MSASYNC eVC4 eVC4SP4 Microsoft Pocket PC 2003 SDK Windows Mobile 2003 ...
TPMS has become a hot topic in automotive electronics. With the introduction of relevant regulations, its demand will surge. For TPMS designers, it is crucial to find a solution with high performance/...

The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[Details]
Note: This STM32 microcontroller is the STM32F103 series. The ADC of Stm32 has DMA function. This is beyond doubt and is what we use most! However, if we want to sample a signal (such as a pulse sign...[Details]
The key is the configuration of registers. The T1 timer (16 bits) of CC2530 needs to configure three registers: T1CTL, T1STAT, IRCON Here is just a brief introduction. For more details, please refer ...[Details]
T1 or T2 are two timers/counters of MCS-51 microcontroller. The first method can use two timers/counters to generate rectangular waves. In order to save interface resources, the second method is used...[Details]
