Renesas CPK-RA6M4 Development Board Review ----ADC [Copy link]

1. This evaluation is about the ADC module of RA6M4

Although the project was built using RTT's Scons before, RTT was never used to create threads, and the modules were always evaluated using the bare metal method.

This review will create a thread dedicated to ADC conversion.

2. Use FSP to create an ADC module and generate code.

Configure ADC module 0, 12-bit, right-justified, single conversion mode.

Enable 6 acquisition channels

Configure the software to trigger conversion. More other conversion modes require the cooperation of some other modules.

Configure transition functions, interrupt priorities, etc.

Configure the port:

There is a potentiometer on the evaluation board, which is connected to the MCU by default. You can rotate the potentiometer to measure different voltage values.

ADC conversion thread code

ADC interrupt callback function code

Actual running test results:

The potentiometer data printed by the serial port is collected normally, and the CAN self-transmission and self-reception of another thread are also running normally.

Code to create a thread using RTT:

The above is the content of this test. You can continue to discuss more complex ADC applications on RA6M4. Thank you.

The next test will use scons to open the RTT built-in driver module and test it on CPK-RA6M4.
