Ivy5661: Potential new target for MicroPython?

See here: https://www.seeedstudio.com/Ivy5661-Wi-Fi-and-Bluetooth-IoT-Solution-SoC-SPRD-UWP5661-Cortex-M4-p-2867.html ARM M4 based, and ZephyrOS seems to be already ported, so it'd be possible to run the Zephyr based version of MicroPython. The interesting thing is, that this chip has both 2.4/5GHz ...

Re: MicroPython Newsletter Issue 1

Too bad that it's only Bluetooth 4.1 and not 5, because 5 offers some interesting long range modes, that would be interesting for embedded electronics. I guess that 5 is just too new to be cheap and reliable. But the Cypress datasheet mentions that it has a FM receiver. Can we use that in Micropython?

How to hide the cursor in the REPL

Is there a way to hide the cursor in the REPL?

Background is, I want to show some live bargraphs from ADC readings, consisting of ASCII characters.
It works well, but there are always flickering remains of the cursor all over the screen.
Can I disable it somehow?

Thanks

Re: New dual-core RISC-V 64bit board

Your allowance is less than $5? :D

BTW, Fun Fact: The board with WiFi contains an ESP8285, so you could in fact run TWO MicroPython instances on one board.

Re: [nRF52] Here is tested and working "proprietary" radio demo code

Great.
This is the Enhanced Shockburst protocol, I assume?

Now we only have to port MySensors to MicroPython.
Piece of cake :D

Re: [STM32H743] How to flash

Thanks for your answer. It seems to be only available for Windows. Is there something similar for Linux?

[STM32H743] How to flash

I feel somewhat dumb here. Could someone tell me how to flash MicroPython to a STM32H743-Nucleo board? Make produces the files firmware.dfu, firmware.hex, firmware0.bin and firmware1.bin. Which of those do I have to flash, and how? I tried copying any of them to the virtual drive of the integrated S...

Function with variable parameters in viper emitter

Hi. I want to write a function, that can either read or write directly to memory. It should have variable parameters, so that: mem32(address, data) Writes to memory, while result = mem32(address) reads from memory. The problem is, to be able to access the memory directly, I have to use @micropython....

Re: [nRF5x] How to connect using WebBluetooth REPL?

Great that it works for you now. I remember having asked asked c45713 about BLUETOOTH_WEBBLUETOOTH_REPL, and he told me that it isn't needed, and therefore I left it at 0, but I didn't think that it'd cause a problem when enabled. BTW: is there a possibility to have some sort of security on the Blue...
