Hello everybody,
new day, new problem…
I’ve bought a mcp23017 board and after shorting address resistors I have it recognized at 0x20, but whatever I connect to it (a simple momentary switch as reference), it doesn’t affect the ui.
I’m powering the mcp board with 3,3V
One of the pin of my switch is connected to PA0 and the other one to GND
can you help me to figure it out how to solve this problem?
You proved the i2c channel as you, no doubt, realise.
GPA & B 6 & 7 should actually do zynthian type things.
This is the allinone board schematic and it appears you are connecting one of the encoder pins which might well mean you wouldn’t see any actual effect…
I have a doubt about push/release actions, if I select push it triggers not depending on the duration of the “click”, instead, if I select release it works in a strange way, not depending on the duration but on the number of clicks in sequence, is this normal?
thank you for the support, I should send you a beer wherever you are
You are unlikely to get the correct setting by trial and error.
You have to be very ordered in adjusting these configs. I tended to just connect one encoder. The Select encoder is the best one to start with. And start by making sure you could successfully detect the Select encoder being pressed. Then get the encoder it’self working, by connecting the PIN-a and pinb settings. Again I can’t remember where it sits in the order so you will have to work this out. You can put a value of 0 as a placeholder…
I don’t remember exactly which pin coincides with which number value, but I think its
Sounds a bit like it’s trying to be an encoder. If you have selected a press pin in the mapping ( the numbers in the text boxes in webconf) and it’s expecting an encoder such things could happen.
Work them out carefully, one by one, and when you have done it and it all works.
WRITE THE CONFIG DOWN!
because if you burn a new ssd you will have to put them in again and it’s a right pain working them out from scratch if you hadn’t written them down.
Do you get the basic idea of how the number relate to the functionality?
The four encoders are the taken in turn on the text boxes on the webconf display. It may seem a little contrived but it date back to the original days when this was all handled on GPIO pins and the i2c 23017 was an addition to deal with running out of pins.
It’s probably a good time to show the encoders and post some photos and how they are wired to the board. There are differnet types of encoder wirings that have confused things in the past.
Hello again,
I managed to make the 4 encoders(+ their switches) working, and also 4 additional switches wired directly to the gpio.
now i’m trying to add more switches (my gpio is pretty empty and there are some free pins on the mcp23017 board) without success
probably the zynaptik config doesn’t help me in any way, because switches pins after the 8th aren’t recognized and I don’t know how to set up more simple switches
I just increased the limit to 12 custom switches (16 switches total, accounting the 4 encoder’s switches).
Are you using “oram” branch? If not, you should start using it because this change is not going to be in stable for a time.
Once you have oram branch updated to the last, you have to add your switches pins and save. Then the needed configuration rows will be added to the list.
Please, be aware that we will cease to support oram 32 bits very soon and we will ask everybody using oram branch to start using the 64 bits image. This will happen in the next few days.
@jofemodo I’ve just updated my branches and added pins and actions but now no one of the switches work, apart from those of the encoders. is there anything I have to change in my settings?
I just checked and i managed to configure 4 custom switches (8 switches total) with my latest changes in oram. I couldn’t test with more than 8, but it should work with 8 at less. BTW, i tested with MCP23017 pins.
