 Topic: SHT45 & SHT85 Humidity / Temp Sensors with PIC16F88 |

| PCM programmer Replies: 9 Views: 15428 |
 Forum: General CCS C Discussion Posted: Thu Jul 13, 2023 11:03 am Subject: SHT45 & SHT85 Humidity / Temp Sensors with PIC16F88 |
| According to the SHT85 datasheet, you're supposed to do a NACK after the
last i2c_read() statement. This is done by giving i2c_read() a parameter of 0. Example: i2c_read(0); On page 10 of the ... |

| MCLR should have a 10K pullup resistor on it. You said Vdd for the PIC
is +5v, so the pullup should also go to +5v. When running the 18F25K80 at 5v, pin 6 (Vddcore/Vcap) should be connected to ... |

| One more small bug. You have two params joined with an OR symbol:
setup_adc_ports(sAN2 | VSS_VDD); But the ccs manual and the .h file show the params separated by a comma. This is the correct ... |

The only changes are the micro going from Arduino based system to using a PIC16F877A. You still didn't tell us 1. The number of pull-up resistors you have installed. Do you have 19 ? 2. The ... |

| You need to do a NACK on the last i2c_read operation.
You are doing an ACK. ACK = 1 NACK = 0 |

| SPI_SS_DISABLED is only used as a setting for an SPI Slave. You are using
the PIC as an SPI Master, so SPI_SS_DISABLED should not be there. Remove it. |
