Things are now up here. https://www.flowcode.co.uk/

We will be making an official announcement soon once the site is a bit more polished.

Hi Ben

Thank you very much Ben.
I have installed FC9 and the ESP toolchain.
A small program written and everything looks fine.
Now I have to get some ESP boards and try the hardware.
It's brilliant!

Stefan

will there be an ESP32 eblock 2 upstream board with ghost available?

wOw! happy to hear that everything works well, I will also try to install this weekend.

Thank you.

Glad it's working well and compiling ok. Let us know if you spot anything that doesn't compile.

We don't have any solid plans for this yet but yes this might be on the cards for development in 2021.

Hi

I would like to ask you some questions about esp32.

Which chips are supported?

Which modules are supported?

Is i2s supported or is support planned in the future?

Hello,

For the list of chips and modules currently included see this post earlier in the topic.
viewtopic.php?p=104063#p104063

No i2s at the moment but might not be too hard to add. I can get it on the list to investigate for you.

Hi Benj

sorry I had not seen the post!

As for i2s I would be very happy if you implement it. Willing to help the implementation in any way!

Kind Regards

Hi Ben

On the Heltec wifi-kit-32 is an OLED 128*64.
How can I use this OLED?

gLCD_SSD1306_i2c
I2C Channel 1
SDA PORTA.5
SCL PORTA.15

Nice board, think that's the first ESP32 board I bought

Hi Ben, Hi Leigh

Nice to hear that you have already chosen the same module.
It's working fine this Heltec Board together with the new FC9.

For my computer a have additionally to download and install this USB driver:

And for the Oled Display:

gLCD_SSD1306_i2c
I2C Channel 1
SDA PORTA.5
SCL PORTA.15

In the board I have, they moved the Pin from the Oled from SDA PORTA.5 to PORTA.4
and I have to set Oled RST on Pin16 to 1.

Hi Ben

Wlan accespoint is working, I can see the "heltec" network, but scanning SSID is scanning but all the string later are empty.

Bluetooth init gives an error.


regards

Stefan

Hi Stefan,

Thanks for the spot with the Bluetooth compilation error. I've now found and fixed this for you.

Let us know if you get anywhere with the WIFI scanning problem. Sounds odd. Was it working initially but then stops working after a while?

Hi Ben

It found 25 SSID and shows the counting up number but no SSID on the display.

regards

Stefan

Wow 25 is pretty impressive

I wonder if we are overflowing the size of the array or something?

Hi Ben

I went into the basement and there are only 9. But still no SSID in the display.

regards

Stefan

Hi Stefan,
I've now fixed the SSID reading, I will ask Ben to push this out on the update system.
Please note that we currently limit the maximum SSID count to 8 (to conserve memory), but we can change this in the CAL if it becomes necessary.
Also the SSID information is an array so starts at 0, not 1.
So before your reading loop you need to set iidss_count = 0 (not = 1)
Regards,
Leigh

Hi Leigh

Thank you very much. Scanning is working now and I changed the array so it starts at 0.
For me is ok to work with 8 SSID.

regards

Stefan
