Hello to all,
I'm working with the MPC5777M. I'm trying to convert the temperature using SAR_ADC_B0 and then send the value via UART, also using INTC (interrput controller) and PIT (timer)
It is unclear if and how to configure the SIUL module. I've seen some examples of configuring this module, but I do not know where to find the information in the manual to configure it.
Regarding the SAR_ADC_B0 I just need to convert PTAT and CTAT channels (channel 120 and 121). To do this, do i need to configure SIUL? And what about UART? Can anyone help me to clarify the ideas?
Thanks in advance
Hi Andrea,
You can simply refer to TSENS example posted here: https://community.nxp.com/docs/DOC-334438
For the reading of ADC internal channels you do not need to set SIUL
To configure other GPIO pins (UART, etc) you should refer to I/O Signal Description and Input Multiplexing table, which is normally attached within a device Reference Manual. It is missing in the latest rev.4.3. You can find it e.g. here https://community.nxp.com/message/890202
