ESP32 arduino sketch talks with QCA7005 homeplug modem
After integration of the pev state machine and exi decoder based on the ccs32 project, the ccs32berta runs into the charging loop, and shows the charging progress on the OLED. The test setup is pyPlc as EVSE, and the QCA7005 on the Ioniq CCM. At the moment the software only uses "pure" SPI communication without using the interrupt-line, also not caring for configuring and confirming of interrupt sources in the QCA. For the given use case, this should be sufficient, because there is no need to react on incoming traffic faster than in the 30ms loop.
