Update progress bar LED during transfers

Calculate the CRC16 checksum for parallel 4 bit lines separately. When the SDIO bus operates in 4-bit mode, the CRC16 algorithm is applied to each lin

Check checksums for received blocks

* I2S format is directly compatible to CD 16-bit audio with left and right channels * The only encoding needed is adjusting the volume and muting if

Start a data in transfer using given temporary buffer. diskDataIn() below divides the scsiDev.data buffer to two halves for double buffering.

Use ADC to implement supply voltage monitoring for the +3.0V rail. This works by sampling the temperature sensor channel, which has a voltage of 0.7 V

card reader operation loop assumption that SD card was enumerated and is working

Reinsert any ejected CDROMs on reboot

Check if data buffer from application has been fully processed. If there is a next one, swap it. If all is done, return true. Assumption: g_scsi_dma.s

Check current build against a saved baseline. Prints only changes.

Compare current build against the latest GitHub release.

Save baseline snapshots to a JSON file.

Full comparison of a single ELF pair.

Compares the prefix of both files and the scsi ID cd3-name.iso and CD3-otherfile.bin matches, zp3.img or cd4-name.iso would not

Load the SCSI read state machine with the address of the parity lookup table. Also sets up DMA channels B, C and D

When a file is called e.g. "Create_1024M_HD40.txt", create image file with specified size. Returns true if image file creation succeeded. Parsing rul

Short delays, can be called from interrupt mode

Called to transfer next block from SCSI bus. Usually called from SD card driver during waiting for SD card access.
