Hello! This is the second part of the tutorial devoted to the analog comparators of the RA2A1 family. In the first part, we learned how to use the high-speed analog comparator for ...

Hi there! RA2A1 family, as I mentioned in the first tutorial, claims to have a rich analog peripheral, which includes: One unit of the 16-bit SAR ADC which has up to 17 ...

Hi again! In this part we’ll mainly put MCUboot aside and will talk about the built-in bootloader which is present in all RA MCUs. This bootloader can operate via either UART or ...

Hello again! In this part we consider the last (but not the least) MCUboot mode. In the first part we considered the Overwrite Only mode, in the second part we considered the Swap ...

Hello again! This is the second part of the tutorial devoted to the MCUboot bootloader. In the previous part we considered what this bootloader is, created the bootloader ...

Hello again! I was asked to write this tutorial prior to the other ones as this topic is quite popular according to how many questions are related to this topic on the Renesas ...

Hi! Welcome back again to CircuitBread. In our previous tutorial, we discussed the RL78 timer array unit (TAU), created a microsecond delay function delay_us(), and created a ...

Hi! Welcome back again to CircuitBread. In our previous tutorial, we discussed the RL78 12-bit interval timer and created a millisecond delay function, delay_ms(). In this ...

Hi again! This tutorial will summarize everything we’ve studied before and join it all in this application. The task for today is the following: create a digital and analog clock ...

Hi! Welcome back again to CircuitBread. In our previous tutorial, we discussed interrupt functions and I hope you have really grasped how interrupts work because from now on we ...

Hello! Today we continue the displays topic but this time we will use a more advanced monochrome OLED display with a 128x64 pixels resolution. Such displays are very widespread ...

Hello again! This time we will have a quite simple but useful tutorial. On the RenesasRulz forum there were several questions about how to connect a 1602 LCD to the RA MCU, and ...

Hi! Welcome back again to CircuitBread. In our previous tutorial, we discussed RL78 GPIOs and reviewed the code in our first project. I hope you have successfully programmed the 8 ...

Hi again! In the previous tutorial we learned how to use the visual FSP configurator and created a simple application that uses the external interrupt to control the button state. ...

Hi! Welcome back again to CircuitBread. In our previous tutorial, we examined the RL78/G14 FPB and created our first RL78 project. But we have not really discussed the code in ...
