The ESP8266 is includet in FC7. Is it possible to include the "new" ESP32 from Espressif also?

Espressif is company desigtning low cost Wireless solutions.
Their ESP8266EX is among the first low cost WiFi IC and popular choice for many makers and creative people who use it to add Internet connectivity to their designs.
Their new ESP32 chip has WiFi and BLE connectivity.
The development boards ESP32 are avaible for less than 20$.

Hello Stefan,

Is it possible to include the "new" ESP32 from Espressif also?

Possible, yes.

I'll see if I can get a module to play with. Hopefully the ESP32 has now calmed down as last time I looked things were changing like crazy and production kept being pushed back.

WIFI and Bluetooth on the same device worries me a bit as the more you add the more horrendous it becomes to do something simple. Though if done well then it might not be the case.

At the moment at Matrix we are pretty busy with various developments so I can't promise anything immediately however there is nothing in Flowcode that stops a user from creating components just like we do.

So if someone fancies having a stab at this then that would be really helpful.

Hi Ben

Thank for the infos. I have already studied the IC a little more. Nice part of the ESP32 is, it has actually a dualcore CPU (2x Tensilica-LX6) and a lot of memorie. One Cpu for Wifi and one Cpu for "software". It would be nice, if with FC7, I could program this procesor. So I dont need an additional CPU like PIC or STM anymore and my new board will be very small and simple.
That would be a new chippack for £ 80. I've been a little patient for this ....

Hi

Any news on support for the ESP's from a post from last year?

Hi Docara,

I have the go ahead to spend some time investigating this again to see what the current state of things are. Hopefully things are a bit more stable now.

I have a ESP8266, ESP12S and ESP32 all sat on my desk in preparation. Hopefully I will find some time for this later in the week.

I don't want to promise too much on this as there is still a long way to go. However ESP32 target now compiling from Flowcode, IO, Delays and I2C up and running so it certainly looks promising

This is a Heltec ESP32 WIFI_KIT_32 I got on Amazon for £11 with a SSD1306 I2C LCD. The LCD works as is with the Flowcode component so that's a bonus.

Hi Ben

That's realy good news.....
Not so good is that amazon will not shipping it to switzerland.....

But the same Modul I think is direct from heltec on aliexpress.

Do you already know if a componet will follow?

Hi Stefan,

It's still early stages but at the moment it looks like we will do a Flowcode 8 chip pack for the ESP32 device so you can compile code to run on the ESP32 directly. We may also include definitions for various boards but these will likely be largely cosmetic to show exposed pins etc. I have yet to get the Bluetooth/WIFI comms working but there will likely be a new component to drive these.

Don't worry too much about not being able to get the board, I am currently thinking that anything ESP32 based should simply work as long as the programming scheme is the same.

Hey Ben,

I would definitely be interested in this component... it would be great for IOT sensors on my bee hives.. presently I’m using a micro plus wifi board.. it would be gr8 to only have to use the one unit and have control of the I/O

Can the ESP 32 support I2C native?.. I’m using a 24bit ADc for the weight measuremet. I can bit bang the 1 wire for temp and humidity

Let me know if I can assist with the dev on the ESP32

Edit...I just checked the data sheet on this baby...it’s a monster.. peripheral count is great....2 x I2C + UARTS and more.Processor looks grunty as well!

Best

Pete

Hi Ben,
Did ESP32 actually made it in to the FC8?
I can not see it in any of target list.

Regards,
Igor

Hi Igor,

It's still early stages

This hasn't yet been released. I'm hoping to squeeze it into the upcoming 8.1 release due out around September but it's currently on a fairly low priority and I'm having issues wrestling with the compiler so it can't say for sure at the moment.

Can the ESP 32 support I2C native?

It sure can, as well as SPI, UART, ADC and PWM. Most things are now in and working, just the compiler to tame

Update on this here for anyone interested.
