GainSpan provides drivers and reference code for most Renesas microcontrollers including the RL78, RX62, RX63, V850, SuperH, 78K0 and 78K0R. Requiring as little as 2 KB of RAM and 6 KB of Flash, the reference code may be used with the IAR Embedded Workbench Kickstart Edition. Drivers are available for UART or SPI interface. To download the reference code, please register on the GainSpan support portal.
For the RL78G14, a demonstration code is available to download on the RL78G14 Renesas Demonstration Kit (RDK) page. The code includes several demo applications:
- Connection to the Exosite cloud, in station/ client mode,
- Connection to a smartphone, in soft AP mode, using the embedded web server hosted on the GainSpan module, service discovery and browser based or native iPhone/ Android apps
- Provisioning and over-the-air firmware upgrade applications
