STM32 talks with QCA7005 homeplug modem

The liboi port has been tested inside the CCS-to-CHAdeMO adapter and successfully charged a few kWh on said chargers

With the STM32F103RE on the Foccci board, the light-bulb-demo-charging on Alpitronic hypercharger worked on the first attempt. Pictures here: https://openinverter.org/forum/viewtopic.php?p=59821#p59821

Using the NUCLEO F303RE development board, the STM32 talks via SPI to the QCA7005 on the Ioniq CCM. The ccs32clara reaches the charging loop, and shows the charging progress on the serial console in the Cube IDE.

• Implement TCP retry to compensate for single lost packets
• Takeover latest state machine updates from pyPLC
• Control the CP line and the contactor outputs
• Add CAN
• Migrate to STM32F103RE, which is planned for the foccci board
• (much more)

• arm-none-eabi-gcc
• Controller: STM32F103RE
