MRDS1322 / Re: How to manipulate pin 4 (DTR) and 7 (CTS) to send RDS data
« Last post by Jan on October 14, 2018, 09:45:23 am »
From 2010, all offered RDS chips support standard RS-232 serial communication which can be established from any OS without need of specialized DLL from us. Such DLL is no longer developed.

The mrdsio.dll uses 3rd party commercial communication components so I'm not able to give you a description how to access these pins in 64-bit Windows. Using such components seem to be necessary.

MRDS1322 / MRDS192 - How to manipulate pin 4 (DTR) and 7 (CTS) to send RDS data
« Last post by keithsw1111 on October 14, 2018, 09:11:43 am »
I have some 32/64 bit software that I want to interface with your chips but I can only find the mrdsio.dll library in 32 bits. From other posts I understand you are not interested in making a 64 bit version which is fine so maybe instead you can share with us how you controlled pins 4&7 from windows using just the standard windows comm port functions. Or maybe even share the source code to mrdsio.dll

FM Scope Script Files / MP3 recording from sound card input (pira)
« Last post by Jan on September 29, 2018, 10:42:25 pm »
1. Save this code as .fms script:

Code: [Select]
;User configurable parameters
; recfilename: Fill full path and file name, for example C:\recording\%date %time.mp3
;              The path must exist!
set(recfilename,C:\recording\%date %time.mp3)

;Script body
recorder.stop
page.show(6)
textwindow.addline(<%date %time> Recording to %recfilename)
recorder.run(%recfilename)

2. Configure the MP3 recorder (Options - MP3 Recorder...)

3. Configure the Task Scheduler (Options - Task Scheduler...)

For example, to start new recording file in each hour, fill following:

Open/Execute - type the script file from step 1 incl. full path
Times - select all days, insert times 00:00, 01:00, 02:00 ....... 23:00

You don't need the P275 device. Just any audio source.

Silence Detector / parallel port GPIO
« Last post by al7ds on September 19, 2018, 12:17:39 am »
It would be really useful to allow parallel port GPIO for silence alarms.  Many PC's do not include a serial port any more.  :(
In addition there are many more pins to control, thus multiple alarms could be configured.

P132, P232 and P332 RDS Encoders / Re: ReadWeb
« Last post by Jan on September 16, 2018, 08:55:26 am »
The https is internally supported by the network stack but that feature is currently not available to the user. You cannot enter https into the READWEB url. We're working on a solution how to make it available for the READWEB command. You may use the Magic RDS facilities instead.

Ok Jan!

Sorry for the late reply. I need another help. I cant read a text from web from a https url. I need to. Is possible?
Thanks

MRDS1322 / Re: no quarz oscillator on MRDS1322
« Last post by Jan on September 08, 2018, 12:12:05 pm »
The C1 and C2 must be placed.

The XTAL pins may be short-circuited by the XTAL case - place the XTAL a few mm above the board or use an insulation pad.

Minimum configuration for getting the oscillator working is:

Pin 1: +5V
Pin 2: XTAL + 22 pF capacitor to GND
Pin 3: XTAL + 22 pF capacitor to GND
Pin 4: +5V via a resistor
Pin 20: GND

Only high input impedance counter can be connected to these pins. Thus I would recommend to measure on pin 5 rather. There should be 57 kHz @ 5 Vpp.

Please post your schematic diagram or better a photo of the board.
