In Topic: SIO Wifi modem with esp8266

Just  a remark, it will not be easy to bit-bang the pia to generate or read serial data.
I had to wire my ESP8266 to joystick-port-1 to get it from a weird 135kbaud uart setting back to life.
Needed to disable NMI/IRQ, kill antic and start sending/shifting on the exact same scan-line.
I used ROL to shift bytes out, were TX was bit-0.
Otherwise, the outgoing bits were not evenly spaced.
But I guess on much lower baud-rates, this is less critical.
Bytes need to be send out most significant bit first, start-bit is zero.
success with this little project :-)

this is why I am looking for the MPP 1000e pinouts. The serial driver has already been written. Very low speed but I don't care about that.

I have a question but it's not related to the topic, 'SIO WiFi modem for ESP8266'.


For fun I would like to connect one of my spare ESP8266 dev boards (NodeMCU clone board) to a joystick port ala MPP 1000E modem. 


Does anyone have the pinout for this joystick port connected modem?   


I thought it was pins Joy2-1 and Joy2-4 for TX and RX (or vice versa) because this worked as a loopback but no luck with the dev board.



In Topic: Question about Action array size

Fri Sep 21, 2018 4:25 PM

BYTE arrays (and alias CHAR arrays) are Action!'s means of doing strings.   The 0th element contains the string length, 0 to 255.


That said, there's not really any bounds checking in Action!.   I would think it would allocate whatever amount of space you specified. Odd that it doesn't seem to do so in your case.

dropbox, now that you are connected AT&H should reveal the v3.4 help document.


Er, that's Dropcheck.  Sorry.  I'm used to typing 'dropbox'

I have a question:


For those who have added RVerter logic to their modules, ESP-1 or nodeMCU/lolin/wemos dev board, have you confirmed that the wifi modem that you created plays nice with real drives?
