Response size seems to always be 10 smaller

[hesa2020]

Hello I wanted to try this awesome project to integrate with my devices however I have been having a few issues, I first attempted with a teensy 3.6 but without the uart stuff just using the builtin HardwareSerial in 9 bits mode but it was like if no data was ever received.

So I went and bought a mega 2560 from a local store today.

Instantly im seeing progress however the m_count from GetResponse doesnt match the response_size in both setup and tube_status by exactly 10

I was wondering if you would have any idea why I am using a Conlux CCM5G.
my PNP transistors are 2N4403 in case it make a differences, I dont have much experience with PNP transistors so I dont know if this one make a signifiant difference.

I filled coins into the machine:

• 12 x 1$
• 71 x 0.25$
• 49 x 0.10$
• 41 x 0.05$

And its reading this correctly, so I am assuming my device doesnt send the full length of data.

However something with the polling is wrong, it keep reading previous state over and over for a while and then randomly changes when it wants so im assuming something with reading is acting funky.

Hi, what exact coin changer do you have? Sadly I dont have any hardware anymore myself so I cant do any debugging or investigation. Do you have any documentation for the coin changer? Maybe it needs to be configured in any way. Could you provide a picture of your wiring?

My device is a Conlux CCM5G, to provide a picture it will be a bit hard since I soldered everything, but it was doing the same thing on the breadboard wired exactly like the example/schematic you provided.

This should be the manual: https://www.vendingworld.com/Manuals/Conlux/CCM5%20Full%20Service%20Manual.pdf

I would like to show you the behavior over a call is it possible ?

hi, did you find the issue?
