mithro | tannewt: okay, I've actually reworked the interface, now each endpoint just has a fifo | 01:18 |
---|---|---|
tannewt | mithro, how big is it? | 01:28 |
mithro | 512 bytes | 01:28 |
tannewt | ah, for each? nice! | 01:28 |
mithro | I think this is the quickest way to get this working... | 01:31 |
tannewt | thats a good place to start | 01:31 |
futarisIRCcloud | mithro: 512 bytes for each endpoint fifo should be enough to get it working for CDC. | 01:38 |
mithro | Guess it's time to test on some real hardware | 01:53 |

mithro | In [7]: wb.regs.usb_pkt_count.read() | 04:07 |
mithro | Out[7]: 127 | 04:07 |
mithro | What did we decide that 80 06 00 01 00 00 40 00 was again? | 04:14 |

mithro | tannewt: On real hardware! | 04:46 |
mithro | tinyfpga: ^ | 04:47 |
cr1901_modern | mithro: Excellent work :) | 04:48 |
mithro | Lots of things I'm not happy about.... | 04:49 |
cr1901_modern | Are most of them "5280 LUTs just isn't enough"? | 04:49 |
mithro | cr1901_modern: Nope! | 04:50 |
futarisIRCcloud | mithro: Great work! | 04:54 |
tannewt | mithro: awesome work! Did you get cdc going? | 05:27 |
mithro | CDC serial port of Clock Domain Crossing? | 05:28 |
mithro | S/of/or/ | 05:28 |
mithro | The second one works | 05:29 |
mithro | Need the software to do the descriptor stuff | 05:31 |
tannewt | Are you using a riscv core? Tiny usb shouldn’t be too bad to port | 05:34 |
futarisIRCcloud | The software to do the descriptor stuff? | 05:34 |
futarisIRCcloud | I haven't used tinyusb, but it looks like it would do the job. I've used btstack, and it is a small embedded bluetooth / bluetooth le stack, for embedded systems. | 05:37 |
futarisIRCcloud | Once the stack is up, the simplest demo would probably be a USB UART device... | 05:39 |
tannewt | I can help with tinyusb. I just added samd support and am working on stm | 06:01 |
