However, in your application `init.c`, `PA0` to `PA5` are mapped to Alternative Function 6 (`GPIO_AF_6`) as EPWM output for motor control. Please review and clarify which pins you want to use for the SPI bus. If there are alternate routing mappings or a second SPI interface (`SPI1`), please specify them. + +> [!CAUTION] +> **Performance Constraint at 24kHz**: `DAQ_Packet_t` is 34-36 bytes long (depending on packing). Transmitting this much data at 24,000 times per second means pushing an SPI bandwidth of almost 7 Megabits per second (if back-to-back), plus software overhead. If standard polling is used, this could take a significant chunk of time out of the 41.6µs period. Please advise if a high SPI Baudrate or DMA is available/desired. + +## Proposed Changes + +### [MODIFY] main.c +1. Add global runtime flag: `bool send_daq_enabled = false;`. +2. Extend `cmd_parser` to check `strncmp(data, "test_data:1", 11) == 0` (enable) and `test_data:0` (disable). +3. Inside the `flag_24Khz_timer` loop, populate `DAQ_Packet_t` structure (using actual `timestamp`, `phase` duty values mapped to current/voltage, `dds_amp`, `dds_ftw`, etc.). +4. Send the structure bytes over SPI0 if `send_daq_enabled == true`. + +### [MODIFY] main.h +1. Provide the definition of `DAQ_Packet_t`. Ensure it has `#pragma pack(push, 1)` behavior to preserve proper byte alignment for parsing. + +### [MODIFY] init.c +1. Create `spi_config(void)` function taking into account the relevant `GPIO_AF_x` mappings and highest reasonably possible `.SPI_BaudRatePrescaler`. +2. Initialize `SPI0` in Master mode. +3. Call `spi_config()` in `SYS_Config()`. + +### [MODIFY] init.h +1. Add function prototype for `spi_config()`. + +## Open Questions + +1. **Which specific GPIO pins** should be configured for the SPI bus mapping to avoid conflict with `EPWM`? +2. **What data** exactly should be mapping into variables like `i_u`, `v_u`, `v_bus`, `error_val` etc? Currently there are `phase[0].duty` and predefined values. Should we mock these fields, leave them as `0`, or link them to specific placeholders? +3. Can we assume **SPI0** in Master mode is perfectly fine for this application? +4. **CRC16 Implementation**: Is the `crc16` field generated by software or a hardware peripheral? + +## Verification Plan + +### Automated/Code Verification +- Compile code to ensure `DAQ_Packet_t` structures are safely populated and no definitions are missing. + +### Manual Verification +- Send `test_data:1` over UART. +- Measure the SPI clock and `MOSI` pin using a logic analyzer to verify data is successfully bursted exactly at the 24kHz rate. +- Parse the resulting values logic analyzer to ensure `DAQ_Packet_t` `crc16` and fields align correctly.
