Re: Compatibility layer for Adafruit CircuitPython drivers on Micropython

I am trying to understand the source of incompatibility. On an example of ADS1015 adafruit: the only line I found through a 30s look at the code is the import of specialized I2C: https://github.com/adafruit/Adafruit_CircuitPython_ADS1x15/blob/33bb64cd991e64a72413819ae86a029227e07bc1/adafruit_ads1x15...

Re: High Speed USB PHY

I second that post. ADC logging is one of the most useful features of micropython.

Re: Putty is slow

It might help to know more. which ESP32 board? which PC operating system? which drivers are you using? which micropython version? ESP32 chip does not have UART on the processor. Which chip is it using? FTDI or SILxxx ... I suspect the following order of error probability: 1. your drivers are not pro...

Re: native and viper decorators on ESP32

1) Compiled micropython loboris on ESP32 WROVER 2) Enabled support for inline xtensa assembler in mpconfigport.h #define MICROPY_EMIT_INLINE_XTENSA (1) 3) tried this simple code, ( nop() operation is not supported it seems ) fail. Any ideas? >>> @micropython.asm_xtensa ... def adcw(a2,a3): ... sub(a...

Re: ESP32 maximum PWM frequency

All PWM channels using the same timer have the same frequency and phase. PWM channel started with different timer will have some random offset depending on time when the timer was started. It could be possible to synchronize two PWMs, each using a different timer, in such way that one is started at...

Re: What are ESP32 SPI Ports for Micropython SPI(1)?

Any idea on ESP32 WROVER what is wrong with the SPI Init? This is loboris Micropython build with ESP32 and March 2017 date. Tried to remove the SD card interface, as it is on SPI, no luck. from machine import Pin, SPI sck=Pin(18) miso=Pin(19) mosi=Pin(23) dc=Pin(32) cs=Pin(33) spi = SPI(1, baudrate=...

Re: MicroPython on ESP32 with SPIRAM support

Why have you enabled the Bluetooth ? It is not supported (yet) and could potentially cause the problem. Bluetooth is not supported in micropyton, or ESP32 WROVER in general? Could you elaborate the difficulty of enabling bluetooth LE, simple GATT or bidirectional string messaging / kind of UART ove...

Re: Project feasibility and board advice.

I have a solution, depending on the requirements and range. This angle deflection sensor is being used on large cranes. Components needed: 1. linear CCD array compatible with micropython 2. focused laser pointer 3. mirror on top of crane Laser pointer turns on, is aligned 90 degrees with the mirror ...
