KaRadio32 Release 1.9

KaRadio32:

Release 1.9 Rev4 - Built on 2019/04/28

New:

• 1.9 R4:
  • wifi.auto command now disable the AP mode if already connected to an AP in the past.
  • I2S corrected for 32bit output stream. Thanks to har-in-air github user.
  • Instant play: new button "Add/Edit", and update fields on cli commands.
• 1.9 R3:
  • blank password accepted.
  • New lcd types: LCD_I2C_ST7567, LCD_SPI_ST7567_pi , LCD_SPI_ST7567, LCD_SPI_ST7565_NHD_C12864
  • New nvs_partition_generator.sh and nvs_partition_gen.py: comment line # comment, now permitted.
  • cli.list correction.
  • Minor corrections.
• 1.9 R2:
  • New option for the active level of buttons.
  • Little bug removed on color lcd.
  • Telnet disabled in AP mode.
  • Key Ctrl space, Ctrl left, ctrl right, ctrl top, ctrl bottom on web page for control.
• 1.9 R1:
  • Labels in the csv hardware configuration.
  • Toggle main/time now permanent. On time display, an event go to the main screen for 3 seconds then return to time screen.
  • More reactive display on lcd.
• 1.9 R0:
  • Improved encoder for new chinese device (shorter pulses) (reverse A/B in case of reverse way)
  • Better vs1053 detection.
  • No more fall back to i2s when the vs1053 is not detected.
  • RSSI display needed a click of a button to start.
  • AP mode on init: the web page starts on the "Setting" panel and the stations list is skipped.
  • Wifi option: If wifi is disconnected choose to reset or wait for the connection on the same SSID:
  • Command wifi.auto("x") with x = 0: reboot, x=1: wait for the SSID
  • For internal reasons, the touch screen needs to be calibrated again.
  • Many small improvements in the code.

For ESP32 see the github page KaRadio32. Release 1.6 R4

ESP8266 Simplest prototype:

- Optional external ram (23LCV1024) support (1:CS/=GPIO16 2:MISO=GPIO12 3:NC 4:GND 5:MOSI=GPIO13 6:SCK=GPIO14 7:GND 8:3.3v)

Attention:
The optional led is now on GPIO2. The blue led on the ESP8266 is blinking at the same rate.
GPIO16 is now the Chip select for the external ram if any.
The external ram is detected at boot time if present.

To upgrade to this release, please flash user1.4096.new.4.bin at 0x1000 ,
user2.4096.new.4.bin at 0X81000 and blank.bin at 0x7e000 & 0x3fe000
After that, all next updates are done with the On The Air (OTA) feature.
New binaries are hosted at http://karadio.karawin.fr .

Loading the esp8266

First use

• If the access point of your router is not known, the webradio initializes itself as an AP. Connect your wifi to the ssid "WifiWebRadio",
• Browse to 192.164.4.1 to display the page, got to "setting" "Wifi" and configure your ssid ap, the password if any, the wanted IP or use dhcp if you know how to retrieve the dhcp given ip (terminal or scan of the network).
• In the gateway field, enter the ip address of your router.
• Validate. The equipment restart to the new configuration. Connect your wifi to your AP and browse to the ip given in configuration.
• Congratulation, you can edit your own station list. Don't forget to save your stations list in case of problem or for new equipments.
• if the AP is already know by the esp8266, the default ip at the first start is 192.168.1.254
• a sample of stations list is on https://github.com/karawin/Ka-Radio/blob/master/ESP8266-Firmware/WebStations.txt . Can be uploaded via the web page.

Feedback

Please tell me if you succeeded or something more can be done, thanks.
The second step will add some hardware buttons (vol + -, station + -, play ...)
