| 17:43.16 | MonMotha | davidc__: trivial until you have to bit bang a 250kHz slave when you were originally told (and spec'd the uC as such) that it was 25kHz :) |
| 17:43.21 | MonMotha | then it's timing hell |
| 17:43.35 | davidc__ | MonMotha: hehe |
| 17:43.46 | davidc__ | MonMotha: yeah.. I've tried to bitbang a 2Mbps slave - its not fun |
| 17:43.58 | MonMotha | heh, this micro was only 2MIPS |
| 17:44.28 | MonMotha | and there was enough latency to the port that I couldn't actually wait for the correct clock transition before changing the data line |
| 17:45.19 | davidc__ | MonMotha: yeah.. I have to give up on the one I was using.... its 250Mips, but the port latency was unberable |
| 17:46.01 | MonMotha | so yeah, that project is definately getting done with a device that supports hardware SPI |
| 17:46.09 | MonMotha | (redone, that is) |
| 17:46.09 | davidc__ | the best I could do was look at CS and try and spit out bits at the right times... but seeing as a port write took one almost one clock cycle :P |
| 17:46.28 | MonMotha | heh, this wasn't quite that bad |
| 17:46.45 | davidc__ | yup, HW spi is where its at.. the final design involved the main micro loading an eeprom, then the switch booting from that |
| 17:46.49 | MonMotha | data was synchronous on the rising edge, change while low, and I would wait for the rising edge, nop, then write |
| 17:47.01 | MonMotha | no time to do a read |
| 17:47.18 | davidc__ | instead of the main micro mimicing the eeprom as I wanted |
| 17:47.31 | MonMotha | I would have used the 8051's UART, but it was already busy speaking MIDI |
| 17:47.45 | davidc__ | MonMotha: heh |
| 17:47.51 | MonMotha | since 8051 UARTs can run synchronous and most have a SPI compatible mode |
| 17:56.58 | prpplague | hmm, i just can't figure out these chips |
| 17:57.06 | prpplague | i know one is a spi eeprom |
| 17:57.19 | prpplague | the other just doesn't make sense |
| 17:57.30 | prpplague | it has something to do with the audio |
| 17:57.51 | prpplague | i see a line go high when music is playing |
| 17:57.58 | prpplague | and i can see some serial data |
| 17:59.02 | MonMotha | prpplague: you sure it's SPI? |
| 17:59.10 | MonMotha | there's also I2S that is often used for audio |
| 17:59.33 | MonMotha | and it has something of a messed up format since it also conveys DAC clocking info |
| 18:00.07 | prpplague | MonMotha: two different chips |
| 18:00.23 | prpplague | MonMotha: one is some sort of storage i.e. eeprom |
| 18:00.33 | MonMotha | yeah, those are often seen in SPI |
| 18:00.44 | prpplague | MonMotha: has a total of 8 lines, which matches with eeprom stuff i'm looking at |
| 18:00.48 | MonMotha | but your audio device, are you sure it's SPI? |
| 18:01.09 | prpplague | MonMotha: see thats just it, i have a seperate dac for audio |
| 18:01.15 | MonMotha | hum, ok |
| 18:01.27 | MonMotha | they usually don't use I2S for anything other than running uncompressed audio to a DAC |
| 18:01.30 | prpplague | MonMotha: but this chip seems to be active when playing some music |
| 18:01.36 | prpplague | MonMotha: yea |
| 18:01.39 | MonMotha | only other instances I've seen SPI used for audio are passing info to decoders |
| 18:01.52 | MonMotha | most MP3 decoders, for example, use SPI for their data interface |
| 18:02.06 | prpplague | MonMotha: right, do does this dac |
| 18:02.15 | prpplague | MonMotha: spi for control, i2s for data |
| 18:02.32 | MonMotha | that's not uncommon. Lots of stuff is I2C/I2S as well |
| 18:02.33 | prpplague | MonMotha: just can't figure out what this "other" chip is for |
| 18:03.08 | MonMotha | ok |
| 18:03.38 | prpplague | trick tricky |
| 18:05.56 | MonMotha | that reminds me, I need to mod an MP3 decoder into one of my webpals |
| 18:13.24 | prpplague | intersting, it appears this chip is connected to the micin for the dac |
| 18:18.47 | prpplague | yep thats it |
| 18:19.03 | prpplague | it just does some music and sends it to the dac mic input |
| 18:19.20 | davidc__ | mmh, maybe a synth of some kind? |
| 18:19.39 | prpplague | davidc__: yea the device plays a standard little tune |
| 18:19.55 | prpplague | the chip only is active when the tune is playing |
| 18:20.34 | davidc__ | ah.. I bet it some kinda a sound synth |
| 18:21.23 | prpplague | davidc__: hmm, any recomendations as to a similiar chip? |
| 18:21.38 | prpplague | davidc__: looks to be spi based |
| 18:22.05 | prpplague | davidc__: appear to have data in, out, chip select and clock |

| 19:31.43 | flyback | no I didn't |
| 19:31.54 | davidc__ | is it rosin core flux? |
| 19:31.57 | flyback | guess I should always use flux :/ |
| 19:32.00 | davidc__ | or just solid |
| 19:32.04 | flyback | yellow stuff |
