Connected SRAM IC doesn't seem to respond.

When I type sys.ram, should I see some info, if there is no ram chip available or it only shows something if there is external ram hooked up.

I Connected external ram 23LC1024.
23LC1024
23LCV1024
PDF 23LC1024
PDF 23LCV1024

23LC1024 has Vhold <== using this one.
23LCV1024 has VBAT

Note: If your chip has a /Vhold in place of /VBAT, the pin 7 must be wired to VCC (pin8) instead of pin 7 to GND for the V series..

1:CS = GPIO16
2:MISO = GPIO12
3:NC = VCC 3.3v
4:GND
5:MOSI = GPIO13
6:SCK = GPIO14
7:VCC 3.3v
8:VCC 3.3v

Double checked wiring still no love.

WebRadio with the VS1053 works so far only at lower bitrates, 24k streams from stream6.jungletrain.net:8024 is the first one I got working, with no stuttering. 64k stutters stream6.jungletrain.net:8064, 128k is worse stream6.jungletrain.net:8128 hopefully the ram helps?

Found another note in the datasheet:
Pin3 is not used in SPI mode and should not be left floating.

Still didn't help though.

the command sys.ram doesn't exist. To see if the external ram is detected, see the log after a reset: => extraram state: 0 0xff ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ show a non detected ram => extraram state: 1 0x30 1234567890 show a detected ram Be sure to wire a0 (adc0) to ground. => extraram state: 0 0xff ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ data : 0x3ffe8000 ~ 0x3ffe8902, len: 2306 rodata: 0x3ffe8910 ~ 0x3ffead7c, len: 9324 bss : 0x3ffead80 ~ 0x3fff1bc0, len: 28224 heap : 0x3fff1bc0 ~ 0x40000000, len: 58432 Heap size: 30648 t0 task: 3fff89f8 t1 task: 3fff8b90 t4 task: 3fff90e8 t3 task: 3fff9730 t2 task: 3fffa480 mode : sta(5c:cf:7f:1c:75:ab) add if0 UART READY TO READ AP1: karawin2, AP2: Station Ip: 192.168.1.253 scandone Trying karawin2, I: 0 status: 1 SCI_Mode (0x4800) = 0x4802 SCI_Status (0x48) = 0x4C VS Version (VS1053 is 4) = 4 SCI_ClockF = 0xB800 I2S Speed: 0 plugin size 18ce 2 c67 plugin start: 7 1 8050 6 scandone state: 0 -> 2 (b0) state: 2 -> 3 (0) state: 3 -> 5 (10) add 0 aid 6 pm open phy_2,type:2 0 0 cnt connected with karawin2, channel 11 dhcp client start... ip:192.168.1.253,mask:255.255.255.0,gw:192.168.1.70 autostart: playing:1, currentstation:23 I2S Speed: 0 Le 05/04/2017 à 06:04, NonaSuomy a écrit :

Interesting, I could have sworn I saw that in this interface.txt guess I was just seeing what I wanted to 😸

The white wire on the right bottom is A0 to GND.

Seems it detects it fine, I guess I just expected too much, that it was going to solve the constant stutter 😞

Any way to figure out what is wrong with any streams above 24kbps.

Using an Adafruit Huzzah (ESP8266).

50Mbps connection, any way to do a speed test on the module?

Did some Fritzing breadboard/schematics for the two different SRAM connections.

I used a Geeetech VS1053B breakout from ebay which was cheaper than the sparkfun breakout.
