Re: [STM32L432 - NUCLEO 32]

This tiny board is cute. I got one for me today and have been trying to port uPy. I made board configuration files and tried to build it then found that STM32L432 lacks some commonly used peripherals TIM3 and SPI2 so it seems that we have to modify some stm32 port sources. If u like smal little boa...

Re: K210(Sipeed M1) run face tracking PT demo with maixpy

Hello Will you consider the same discount to be given on those same backers in Indiegogo in case they would order again? In my case, I am short of cash right now that I would order different package, but maybe after December I could order more. Sure, We will give discount or even donate boards for ...

Re: K210 basic benchmark test

I don't think that your tests r very valid tests. If you see the promo video https://www.youtube.com/watch?v=9q8YzZYH3o4&t=80s you will see at starting at 1:15 u will see it running a NN for face detection. It is capturing the image from the camera then processing the image through the NN then sendi...

Re: Unable to operate with flash on Lolin board

I built a number of boards of my own design myself. I built the first 10 using cheap CP2104 of aliexpress and about half of them failed. I built about another 25 boards using CP2104 brought from Digikey and all work correctly. I had the same problem with the pca9685pw chip I was buying off Aliexpres...

Re: Unable to operate with flash on Lolin board

The Lolin boards have a history of hardware failing.

I think they have been using some bad clones of the CP2104 Uart to USB that is causing the problem.

see one users videos on fixing the problem https://www.youtube.com/watch?v=OrQWos9VcgM

Re: zmodem

Ok so most commonly used uart-USB bridge is the CP2104 and datasheet quotes "Baud rates: 300 bps to 2 Mbits"

So first why is 115200 the standard default and how do I change the firmware to run at these higher speed?

Re: zmodem

I also read that zmodem uses sliding windows that means it sends the next block of data before the receiver completes checksum and sends back ack/nack this means speed is not lost lost in waiting for a ack back.

Re: ESP32 documentation

For the record, as well as more accurately describing the ESP32 port I'm seriously considering introducing an even simpler Quick Reference that applies to all ports (at least PyBoard/8266/32). This could live under General Documentation for MicroPython. Then the port-specific quick references shoul...
