pic16lf18325 I2c不工作问题该怎么解决？

我使用的是使用MCC V3.15的PIC16LF18325微芯片。我在这个项目中使用了SPI和I2C，我很高兴地说SPI部分工作得很好，而I2C则不工作。我已经将RC4设置为SCLK2和RC1，设置为SDA2（使用MSSP2），并且当我编译代码并执行masterWrite/masterRead时，没有时钟线或数据出来。看是浮动SCLK，数据很低。线路上硬件上唯一明智的就是2 10kohm上拉电阻和3个传感器（正确，我保证了三倍）。这个芯片有MCC V3.15的已知问题吗？它确实正确地设置了寄存器吗？这里它们是：LATA=0x0;LATC=0x0;LATC=0x0;WPUA=0x0;WPUC=0x0;ANSELA=0x37;ANSELA=0x37;ANSELC=0x37;ANSELC=0x5;TRISC=0x38;TRISA=0x13;TRISA=0x13;RC1PPSbits.RC1PPS位.RC1PPS=0x1PPS=0x1B；//RC1->/RC1->MSSP1;MSSP1->=RC1PPS位.RC1PPS=RC1PPS=RC1PPS=RC1PPS=0x1PPS=0x1PPS=0x1x1A;//RC4->MSSP2:SCL2;RC0PPSbits.RC0PPS=0x18；//RC0->MSSSCK1;RC2PPS比特.RC2 SCK1;RC2PPS位.RC2PPS位.RC2PPSS=0x19；//RC2->MSSP1/RC2->MSSP1:RC2RC2RC2RS2PPS位.RC2RC2PPSS=0x19；//RC2->；MSSP1：SDSP1：SDOSDO1/RC2->；MSSP1：SDSP1：SSP2DADADADADATPPSP2DATPPSP2DATPPSPSP2DATPPSSSSP2：SDA2；SSP2CLCLCLKPPSSP2CLKPPS位.SSP2CLKPPPPPPPPPSPSPSPSPSPSPSSSSSSS0=0x14；//PPSLOCK=0xAA;PPSLOCKbits.PPSLOCKED=0x01；//lock PPSGIE=state;SSP2CON1=0x28SSP2CON3=0x00SSP2ADD=0x00SSP2ADD=0x03SSP2STAT=0x00也可能是我使用I2C函数错了，这是我的实现，用于从LPS22HB接收压力数据：voidgetPres.(void){uint8_t status=0;uint8_t._top=0;uint8_t._mid=0;uint8_t._low=0;I2C2主写(LPS22_CTRL_REG1，1，LPS_地址，&状态)；I2C2_主写(0b000000000100010，1，LPS_地址，&；状态)；I2C2_主写(LPS22_CTRL_REG2，LPS22_CTRL_REG2，1，LPS_地址，&；状态；LPS2S22_主写(LPS22_CTRL_REG2，1，LPS_地址，&；状态；LPS22_REG2，1，LPS_地址，&；状态)；I2C2_主写(LPS22_主写(LPS22_CTRL_CTRL_REG2_REG2_REG2_REG2，1_PRESS_OUT_XL，1，LPS_Address，&staI2C2_MasterRead(压力_低，1，LPS_地址，&状态)；I2C2_母写I2C2_母写I2C2_母写I2C2_母写I2C2_母写母写(LPS22_PRE_PRE_PRE_OU_OU_H，1，LPS_LPS_地址，&；状态；1，LPS2S22_LPS_PRE_低压_PRESS_PRESS_PRESS_OUT_L L，1，LPS_地址，&；1，LPS_地址，&；状态)；I2C2_母写I2C2_母写I母写I2C2_母写I母写I2C2(LPS22_母写LPS22_PRE1，LPS_Address，现状；

    I am using a PIC16LF18325 microchip using MCC v3.15. I am using both SPI and I2C for this project and I am happy to say the SPI part works perfectly, the I2C on the other hand does not work.

I have set RC4 to SCLK2 and RC1 as SDA2 (using MSSP2) and when I compile the code and do a masterWrite/masterRead there is no clock line or data coming out, all I see is a floating SCLK and the data is low.

The only things hardware wise on the line are 2 10kohm pull up resistors and 3 sensors attached (correctly, I made triple sure). Is there known issues with MCC v3.15 for this chip? Does it definitely set the registers correctly? Here they are:

LATA = 0x0;
LATC = 0x0;
WPUA = 0x0;
WPUC = 0x0;
ANSELA = 0x37;
ANSELC = 0x5;
TRISC = 0x38;
TRISA = 0x13;

RC1PPSbits.RC1PPS = 0x1B; //RC1->MSSP2:SDA2;
SSP1DATPPSbits.SSP1DATPPS = 0x15; //RC5->MSSP1:SDI1;
RC4PPSbits.RC4PPS = 0x1A; //RC4->MSSP2:SCL2;
RC0PPSbits.RC0PPS = 0x18; //RC0->MSSP1:SCK1;
RC2PPSbits.RC2PPS = 0x19; //RC2->MSSP1:SDO1;
SSP2DATPPSbits.SSP2DATPPS = 0x11; //RC1->MSSP2:SDA2;
SSP2CLKPPSbits.SSP2CLKPPS = 0x14; //RC4->MSSP2:SCL2;
RA5PPSbits.RA5PPS = 0x14; //RA5->EUSART:TX;
PPSLOCK = 0x55;
PPSLOCK = 0xAA;
PPSLOCKbits.PPSLOCKED = 0x01; // lock PPS
GIE = state;

SSP2CON1 = 0x28
SSP2CON3 = 0x00
SSP2ADD = 0x03
SSP2STAT = 0x00

It could also be that I am using the I2C functions wrong, here is my implementation to receive pressure data from an LPS22HB:

void getPressure(void)
{
uint8_t status = 0;
uint8_t pressure_top = 0;
uint8_t pressure_mid = 0;
uint8_t pressure_low = 0;

I2C2_MasterWrite(LPS22_CTRL_REG1, 1, LPS_Address, &status);
I2C2_MasterWrite(0b00000010, 1, LPS_Address, &status);
I2C2_MasterWrite(LPS22_CTRL_REG2, 1, LPS_Address, &status);
I2C2_MasterWrite(0b00011001, 1, LPS_Address, &status);
I2C2_MasterWrite(LPS22_PRESS_OUT_XL, 1, LPS_Address, &status);
I2C2_MasterRead(pressure_low, 1, LPS_Address, &status);
I2C2_MasterWrite(LPS22_PRESS_OUT_L, 1, LPS_Address, &status);
I2C2_MasterRead(pressure_mid, 1, LPS_Address, &status);
I2C2_MasterWrite(LPS22_PRESS_OUT_H, 1, LPS_Address, &status);
I2C2_MasterRead(pressure_top, 1, LPS_Address, &status);
