RTC example code

JIBIN_7 — Tue, 09 Apr 2024 07:10:13 GMT

Hi, I am trying S32K312 microcontroller with external RTC (DS1307) through I2C communication. Is there any examples related to it?

I saw from your previous question that you were referring to Example S32K312 I2C Transmit & Receive Using DMA DS3.5 RTD300

DS1307 is not an NXP product, so there is no project for this device. 0x68 is the I2C address for DS1307. Did you change the Slave address in S32 Configuration Tool?

Best Regards,
Robin

I updated the slave address to 0x68 and tested the same, it is not working. Can you please suggest?

Please don't just tell me this doesn't work, I need more information in order to help you faster.
For example, sending the I2C waveform captured by the logic analyzer allows us to check whether S32K3 sends the correct slave address.
