Quick question; has anyone been able to use SPI2 (hardware SPI) to receive data on the Espressif ESP32-WROVER-B?

Follow up question; which pins did you use?

Thanks 🙂!

The reason I asked is because I had an issue with reading data using the HW SPI.

As suggested by @Gordon, I've tried flashing Espruino 2.06, and an issue seems to have been introduced between Espruino v2.06 and 2.08.

I've attached some screenshots where I use the ESP32-WROVER to read from a chip which is expected to respond with [0, 18]. Be aware that with v. 2.06 SPI1 seems to have been used where we'd use SPI2 today, thats why I'm using it in the examples on v. 2.06.

I post this just for reference, I'll open an GitHub issue.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
