Re: [STM32H743VI] Building firmware for STM32H743VIT6
Have you seen this repository? https://github.com/mcauser/MCUDEV_DEVEBOX_H7XX_M It doesn't compile too, but i got it running following the issue comments. There are also comments about the clock settings in the issue section. Yes, it was one of the references when I created the board definition. I ...

Re: [WEACT_STM32F411CEU6] unable to re-flash firmware
Not sure if it's related to your issue - I got my mine two weeks ago and had some trouble getting the board into dfu mode to flash the firmware, so I contacted the customer service of WeAct and they said it's due to the low temperature, and you need to warm up the oscillators and the MCU with your h...

Re: Timers and/or uasyncio
Hi Peter, I have a similar question. In my case, I need to sample at 100us interval with pyboard's ADC - what's the recommended way to have it work with my other codes using uasyncio? Thanks in advance! ... I only very recently started to experiment with at asynchronous coding, so this is helpful. I...

Thanks a lot. I ordered a few of them, and will test when I get them.

Re: VL53L1X ToF distance sensor - adapting to micropython
Thanks for the link! I was looking for this driver for quite a while. Also, would you provide an example for your change_ide method, say how to correctly initialize 5 sensors? What's the type of the variable new_id? Thanks again. So I'm working on Roz, my bioloid quad walker, and I've built a new he...

[STM32H743VI] Building firmware for STM32H743VIT6
Hi, I have got an STM32H743VIT6 dev board which I'm trying to build firmware for. I copied the configurations of NUCLEO_H743ZI and started from there. However, there are still some questions I haven't got the answers after hours of searching regarding the config of mpconfigboard.h ... So I turn to t...

Re: Advice needed - optimize performance: converting dictionary to string (csv))
This is even faster: key_list = [] item_list = [] for key, item in the_dict.items(): key_list.append(key) item_list.append(item) transposed = [t for t in zip(*item_list)] if not omit_keys: csv_title = delimiter.join(key_list) + end else: csv_title = '' csv_body = str(transposed).strip('[()]').replac...

Re: Advice needed - optimize performance: converting dictionary to string (csv))
Well, I found a quicker way to do the convertion - it may not be a nice way, but it does help speed things up. Firstly, I do the transpose by: for key, item in the_dict.items(): key_list.append(key) item_list.append(item) transposed = zip(*item_list) rather than multiple iterations. Then I directly ...
