ZXPand+ IDC10 Serial port ideas!

Post by tdg8934 » Tue Aug 15, 2017 3:26 pm

I was just out at the Parallax.com website and looking for asynchronous serial devices (i.e. 2400, 9600, etc. bauds) and there were more items than I thought to communicate with the ZX81/TS1000 with a ZXPand+. I found the 2x16 & 4x20 LCD displays, Bluetooth for SPP (Serial at 9600), RFID (Serial at 2400), Text to Speech (multiple bauds), Basic Stamp 2 (BS2) micro-controllers, and possibly more. What to buy next to experiment with....?

Having fun!

Tim

hi
what about a zx81 with bluetooth, now that would open up a field of opportunities there

It's certainly doable with the Parallax Bluetooth for SPP using ZXPand serial at 9600 baud.

I have been away from this forum for such a long time now due to a lot of things going on in my life. However, let's see if I can get back into the groove.

In response to my thread from before about ZXPand+ serial devices, I see that Parallax now has a UART controlled Fingerprint Scanner. I may try to get this going over the summer as time permits. Either way I wanted to pass it along.

Re: ZXPand+ IDC10 Serial port ideas! - mini thermal printer

Post by tdg8934 » Tue Jul 16, 2019 6:55 pm

This morning I ordered from Adafruit their mini thermal printer https://www.adafruit.com/product/600 which works on TTL serial. Since I already figured out how to use the ZXPand+ IDC10 connector for TTL Serial for a serial Parallax LCD display download/file.php?id=4377 and viewtopic.php?f=6&t=2505, this shouldn't be too hard to adapt for the mini thermal printer. I also bought one of their new arduino compatibles called the Metro to experiment with and learn the example code to then carry it over to the Timex Sinclair 1000 (ZX81) using the ZXPand+ IDC10 serial pins. More to come...

I received my Adafruit Mini thermal printer from china - Cashino CSN-A2 (https://cdn-shop.adafruit.com/datasheet ... Manual.pdf) - Manual spells Kashino but I have seen it online as Cashino. Anyway...I got it working on test code examples from Adafruit on an METRO 328 - Arduino and tonight I will try test code examples on a Raspberry Pi Zero Wireless. It uses RX, TX so I can use the UART or a Serial to USB adapter I have. I just have to make sure I use it correctly as the Raspberry Pi uses 3.3v not 5v I believe. Ultimately I want to write function like code for a ZX81/Timex Sinclair 1000 with ZXPand+

Is there a way to include functions (like printer.h) for the ZX81/Timex Sinclair 1000 with ZXPand+? I hope not to have to go the Assembly language route but I know on the serial port on the ZXPand+ I'll have to POKE into the 1 REM statement which is fine. I don't want to have to do the entire program in Assembly. Ideas / thoughts?

Thanks,

Tim
