got hold of a 40 pin CO10444 ready when you are :drool:

Hi, I'm building a MB64 and would really apprechiate some help with the button handling I trying to get the led's for "onOnly" buttons to stay on until the next button in that shift reg. is pushed I use this code in the mb64_buttons.inc file: ;; (button value stored in TMP1) MB64_BUTTON_OnOnly ;; when on: send button value defined in dump ;; when off: send nothing BRA_IFSET TMP1, 0, ACCESS, MB64_BUTTON_NotifyChangeEnd ;; turn off SR1 8 LEDs SET_BSR MB64_BUTTON_VALUES_SR0+0 setf MB64_BUTTON_VALUES_SR0+0 SET_BSR MB64_BUTTON_VALUES_SR0+1 setf MB64_BUTTON_VALUES_SR0+1 ;; save status of button rcall MB64_BUTTON_Hlp_SaveStat rgoto MB64_BUTTON_Send this works in a way, but it affects the other buttons as well see video I need help to have the first 8 led's only light the last pressed og theese 8, the next 3 toggle, and the last 4 only light the last pressed of theese 4 I have posted this the wrong place earlier, hope this is the right one

sorry about that was trying to embed the youtube video, and it all went pearshaped

here is a short video of how the buttons and LEDs work now sorry, I can't embed TK, please can you help me out I have built the hardware and ordered the frontplate :( here is the code I have changed ;; (button value stored in TMP1) MB64_BUTTON_OnOnly ;; when on: send button value defined in dump ;; when off: send nothing BRA_IFSET TMP1, 0, ACCESS, MB64_BUTTON_NotifyChangeEnd ;; turn off SR1 8 LEDs SET_BSR MB64_BUTTON_VALUES_SR0+0 setf MB64_BUTTON_VALUES_SR0+0 SET_BSR MB64_BUTTON_VALUES_SR0+1 setf MB64_BUTTON_VALUES_SR0+1 ;; save status of button rcall MB64_BUTTON_Hlp_SaveStat rgoto MB64_BUTTON_Send thanks in advance

Thanks for the update on the progress I'll go TIA "chip picking" then so I have some for when the PCB's are ready :)

I'm bulding a MB64, and have a problem I need help with I need the buttons and leds to work so that only the last pressed button's LED light up I have used the code in this post this works sort of, but it affects all types of button press, not only "onOnly" like I would like it to also I would like it to only affect the buttons within the same shift register I use 2 SR, the first have 8 buttons with it's LEDs, and all 8 have an "onOnly" message I would like these to only light the last pressed in the second SR I have 3 buttons with "Toggle" message that I would like to light LED when pressed and turn off LED when pressed again and I have 4 buttons with "onOnly" message that I would like the LEDs to light up only the last pressed of these 4 Is it possible to have the code from the post I linked to to only work for "onOnly" buttons and only within the same SR I would really appreciate some help with this, my coding "skills" are limited to editing :(

I'm making a dedicated controller for my midiNES I'm not using a LCD or menu buttons or encoder for a CS It has 24 pots, 16 buttons, 16 LED's A couple of questions that I would really apreciate some direction on: -The LED's for the toggle buttons are in reverse order, can this be fixed in code or do I have to resolder? -Button nr.1 does not send any midi message (the rest of the buttons do) any idea why? -Since I am not using a LCD or menu buttons, should/could I disable this somewhere? I have attached the files I have uploaded the .txt file is an .ini file for sysex setup_midibox64.asm midibox64.txt

DUH! It was the MIDI connection pins For some reason I assumed that the pins corresponded to the holes for the MIDI sockets, but it's the opposite Up and running :)

thanks I have tried that now, but no difference I have meassured voltage to the 2 places on the PIC and on the Opto, all fine I can't see how the parts I have left out can affect the MIDI could it be the crystal?

I am building a MB64 with modules from SmashTV I have already built 2 MB SID's so I am familiar with using MIOS studio I have built the Core, and MIOS Studio can't connect to it. On the Core I have left out the Bridge rectifier, the "huge" el.cap, C6, voltage regulator, transistor and pots As I understand these parts are for powering the Core and for the LCD, is this correct? I am powering the Core from another 5V source, and I am not using a LCD +5V and Ground connected to the voltage regulator position I have checked all solder joints, tried with another PIC and another Optocoupler Checked the MIDI sockets etc. My MIDI interface and cables works fine with MIOS on my MB SID's any suggestions?

how's your project going? I would really like to build this Do you know of a place that sells TIA chips, or do they have to be "picked"

Ok, yeah, I see it now thanks I have a 40 pin YM2149F and a 28 pin AY-3-8912A do they sound the same? any preference?

I really like your project I have a couple of chips and I'm thinking about building it I have a question about the envelope shapes you have 8, but in the spec sheet it states 10 are some of them the same or similar?
