Re: MicroPython on ParticleIO Argon ESP32

After googling the board it looks like your flashing the firmware to the main processor the nRF52840 not the ESP32

Re: Issues blinking ESP32 onboard LED

Well u can't use that pin for both a UART and a general GPIO at the same time it is either 1 of the other. I would assume that the blue LED is connected to that pin for the purpose of seeing that your serial port is transmitting not for the purpose of using it as a general LED. If your really need t...

Re: Issues blinking ESP32 onboard LED

GPIO1 is the TXD0 pin on the UART serial used by the REPL it can't be used for anything else with MP

It the LED is connected to it then it should flash when ever data is being sent to the serial terminal.

Re: Questions and wish list about Pyboard D

ok then a little more complex than just using current SPI function and altering them to be I2S For a continuous flow of data like I2S needs then double buffering DMA can be used where it uses 2 different RAM buffers and when it is finished transferring 1 buffer it flags an interrupt then moves to th...

Re: Questions and wish list about Pyboard D

So I have only used I2C, SPI and UART but I would assume software wise I2S implementation would be very similar infact on the STM32F405 it is a type SPI transfer. Without reading the details in the reference manual I would assume it could be as simple as setting the I2S bit in the SPI configuration ...

Re: Questions and wish list about Pyboard D

I'm not in a position to answer this definitively but I suspect it still isn't implemented. Some years ago a user built an I2S skin and attempted an I2S implementation for the Pyboard. Alas he never completed it to the point where the code was reliable. It needs someone with C skills and a good und...

Re: ESP32 PIN.OUT voltage

The bottom line is that you can use the MCUs pins to operate switches not for supply power to drive things.

The MCU needs to switch on the power supply to your pump not power your pump :)

Re: 5x5x5 Rubik's Cube solving robot

I have optimized the robot a lot more and now have it solving the cube in 4:45mins, as far as I am aware it is the fastest 5x5x5 solving robot anyone has built so far see https://www.youtube.com/watch?v=sD4bG8hPYLQ&feature=youtu.be I have uploaded the code that drives the robot to githuib see https:...

Re: i2s compatibility

Lobo port has had some I2S stuff for a while. I did play with it a bit back when it was first released. He had a couple of nice features like using the I2S to feed the DAC via DMA to pay a WAV file with a simple amp and speaker, this is the amp that I used https://www.ebay.com/sch/i.html?_from=R40&_...
