Hello everyone!
I encountered a strange problem when I measured the pressure under normal pressure. It works fine when debugging the sensor. After the sensor is powered down and restarted, the measurement pressure prompt is out of range. I want to know how to get back to normal after a power outage, or what details I need to pay attention to (I have tried other programs to make sure the chip is working properly.)
Maybe I didn't describe it clearly. I just don't know why the reading pressure value will be out of range. Is it related to stop mode or other configuration?
Thanks in advance!
Imitate the routine, use the following code before reading the pressure, the situation has improved.
TPMS_LF_ENABLE(CLEAR);
TPMS_INTERRUPT_FLAG=CLEAR;
TPMS_READ_VOLTAGE(TempArr);
补充记录
后面发现通信协议中，有个状态字节包含高压的标记，当该位置1时，气压会显示在高压范围
