Documentation: wiring cmt2300a esp32 devkit #998

I am looking for a wiring diagram to connect a cmt2300a to a esp32 devkit. I want to connect solely a cmt21300a (no nrf24l01+). Connecting the csb and fscb is straight forward but where is irq connected to. As the systems settings have solely 3 input fields (csb, fcsb, irq) where to connect the sclk ping of the cmt2300a.

Right now I am getting constantly something like:

001oc commented 1 year ago

maybe that is important too. I have used the self compiled current hms branch.

lumapu commented 1 year ago

that branch is not updated any more, please use development03. I will delete the hms branch in near future

001oc commented 1 year ago

@lumapu - thanks for your advice, I have moved to develeopment branch shortly after I having started my question. But this is not an answer to my question. I am looking for a wiring diagram for solely having a CMT2300A connected to the ESP - idealy I would like to have an advice how to config this inside the software. Thanks

mirek-z commented 1 year ago

Hello I join the question about esp32+cmt2300a configuration

lumapu commented 1 year ago

Have you checked the issue #904?

Bei mir hängt das Modul am VSPI (SCK und MOSI)

Daraus ergibt sich als feste Pins, ESP zu CMT: D23 - SDIO D18 - SCK

und frei wählbar: D17 - CSB D26 - FCSB D34 - GPIO3

mirek-z commented 1 year ago

I'm not doing well, could I write a call? cmt2300 sclk sdio csb fcsb these 4 pins to what pins in esp32. i only have cmt module without nrf32. and then how to set it in the software because there are only settings for the cmt module: csb fscb irq I will be grateful for help because somehow it doesn't work :)

001oc commented 1 year ago

@lumapu Yes, I checked that before, thanks. The question there is if and how to operate nrf24l01 and cmt2300a both together parallel - which is working at all. My question is how to run solely a cmt2300a without a nrf24l01. I dont habe any HM, I only have HMS and HMT running.

lumapu commented 1 year ago

I did a quote on the interesting part, the pinning. Ahoy will support both generations, it depends on your settings which module will be used.

@mirek-z do you need a translation of my post before?

mirek-z commented 1 year ago

definitely yes, because the soft has CSB, FCSB and IRQ settings and CMT has SCLK SDIO CSB FCSB, how to set it in the soft?

jmeister79 commented 1 year ago

Same Problem here. Wired up CMT to an ESP32 and cannot get it working. What does IRQ mean? The Boards are wired as follows:

CMT: GPIO12 - SCLK GPIO14 - SDIO GPIO27 - CSB GPIO26 - FCSB

nrf:

GPIO4 - CE GPIO5 - CS GPIO18 - SCK GPIO23 - MOSI GPIO19 - MISO GPIO16 - IRQ

However, I cannot bring the NRF to work: "your NRF24 module can't be reached, check the wiring, pinout and enable"

CMT says:

15:34:05 I: TX 865.00Mhz \| 15 80 42 26 55 81 00 17 65 80 0b 00 64 9e d9 cd 00 00 00 00 00 00 00 00 7c c5 8b
15:34:05 W: CMT TX failed, code: 2

And I am not sure what to select for IRQ of the CMT.

lumapu commented 1 year ago

for the CMT part I use the following pinout with an ESP32-30 Pin module: grafik

SDIO has to be connected to D23-VSPI-MOSI and cannot be placed somewhere else. Same for SLCK, it has to be connected to D18-VSPI-SCK

For IRQ (Interrupt Request) you need a interrupt capable pin of you ESP, I use D34 for that.

For NRF (optional) you can use the following pins: D14: SPI-CLK D12: SPI-MISO D13: SPI-MOSI

for CS, CE and IRQ you have free choice.

mirek-z commented 1 year ago

I have it exactly as described, but in the console I have it all the time: 

19:56:43 I: TX 868.00Mhz | 56 81 03 73 23 81 00 17 65 02 15 21 14 14 41
19:56:43 W: CMT TX failed, code: 2

i only have cmt 2300 and esp32 module. I am trying to connect to HMS-2000 4T

mirek-z commented 1 year ago

and shouldn't the microinverter be disconnected from the dtu? or something? wires well connected and no contact with hms

lumapu commented 1 year ago

would be nice if you post the serial output from booting up Ahoy

I meant the log during boot up - once the CMT module was initialized. I think the ESP can't communicate with your radio

lumapu commented 1 year ago

sieht eigentlich gut aus, weiß nicht wo es hakt.

mirek-z commented 1 year ago

maybe from the beginning. is this diagram ok? esp32_e49

lumapu commented 1 year ago

your pinnumbering is wrong, check https://www.studiopieters.nl/esp32-pinout/ 3.3V for the ESP32-38 is pin 2. Then P34 is pin 6 and P26 is pin 11. The other connections are correct.

DejanBukovec commented 1 year ago

@jmeister79 did you make it work ? I have ebay board which have same configuration(OpenDTU pinout): "clk": 12, "cs": 27, "fcs": 26, "sdio": 14,

Im set this setting: slika

But can't test it because still waiting inverter... When Im insert some serial of HMS inverter and check console I get this:

@lumapu I have done this, but the inverter data is not yet available, do I need certain settings again? what is the correct configuration?

I use an HMS microinverter and an Ebyte E49 900M20S chip

i have desolderd the Nrf modul now it workes fine20240705_135011.jpg

stefan123t commented 1 month ago

@001oc @mirek-z do you still have an issue with wiring the CMT2300A connections ?

001oc commented 1 month ago

As @mo0815 statet after removing the NRF modul it seams to be working - i believe it is a problem with either the poor quality modul or the power supply or both of them.

I have done a couple dozend of opendtus and from my expieriences its always a problem with either cheap NRF modules or more often poor powersupplies. Most of my problems were solved when using a reliable and proven capable power supply. If that does not helped, the problem was typically a cheap chinese rebuild of an NRF module. Mostly they are functioning in general but have difficulties to establish a reliable radio signal which mostly ends up in (at least) unstable function. After using good quality power supply and spending some bucks more per NRF modul these problems never come up again. When following this simple rules you will see that opendtu is a very stable and reliable project.
