Re: [E3-hacking] About connecting to the serial on the E3

It belatedly occurs to me that inverted TTL serial probably looks just like non-inverted TTL serial except the data will be garbled. So most likely you have it hooked up to the right pins but you somehow need to invert the signal. I found an article, which shows almost exactly the same result that

Its still getting garbled text with CP 2102. 15200 was a typo on here.. 😊 in Putty its 115200. I thought I try my FTDI 232,its text is garbled too… it does it on both of them.?? I am connecting it to pc then to FTDI232 or CP 2102 they connect to E3 then running Putty on PC and unplugging the E3

Re: [E3-hacking] About connecting to the serial on the E3

I think this should work, but can't remember if rx & tx are the right way round. Google TTL-232R-3V3-AJ. From what I remember there were 2 versions of pbl, one was hacked to allow a new kernel. The upgraded version was encrypted / required a signed binary. But Amstrad never released the key. the ke

Re: [E3-hacking] About connecting to the serial on the E3

Yes, you're right, that's clearly nonsense. Why would the E3 generate an inverted signal, anyway? If it's just the raw output from the processor (which I think it is) then it should be standard TTL levels, because it's supposed to be fed into something like a MAX232 for conversion to RS232 levels.

Thanks for the advice people.. 😊 I don’t have RS232 on my PC, I only use USB to TTL on it. Do I use a headphone jack that's mono so it only has 3 connections on it, not a stereo one, any one got a pic of it so I know what to get(I know what it looks like just need to see if it a normal headphone

Provided the E3 and the USB device ran off isolated supplies, you might be able to get away with connecting the 5V (or whatever) on the USB adapter to the GND on the jack. That would cause the logic levels to be interpreted inverted. Note, this does not constitute advice, not responsible for any d

Re: [E3-hacking] About connecting to the serial on the E3

If the E3 has a TTL serial port as reported here then a USB to TTL serial adapter should work fine. No need for line drivers or level adjustment, nor any need for inverters. Just connect it straight through. These USB to TTL serial are very common and cheap because they don't have the MAX232 (or si

Okay, so this is unclear. That article's talking about connecting the emailer via actual RS232 via a TTL-to-RS232 level converter. Nobody does this any more; instead you use a USB TTL serial adapter. But it sounds like the emailer's output levels are inverted, so logic 1 is 0V and logic 0 is 5V. I

RS232 is actually +/- 12V! My recollection is that the E3 runs at 0V/5V (I described it as TTL back in 2003). A 3.3V serial converter might work, I couldn't say. On Wed, 3 Apr 2019 at 20:52 Nick Griffin wrote: > On your site.. > “In order to talk to the E2, you need the appropriate cable. Irritat

On your site.. “In order to talk to the E2, you need the appropriate cable. Irritatingly, while the E2 has a serial port, it runs at TTL line levels not RS232 levels. This means that if you're going to connect it to a PC, you need a line level converter” So I can use a CPC 2102 USB to TTL seria

As far as I know when you connect this to serial you don’t get a console, like if you connect TheC64 Mini to Putty using a CPC 2102 USB to TTL serial convertor, you can log on with your root user and password so you can add files, change games and edit files and that ,TheC64 Mini uses Uboot to b
