if your code uses SPL, it's not datasheet compliant - yes, ST's own code doesn't follow the datasheet
What is SPL?
The Standard Peripheral Library, an outdated API provided by ST but still somewhat widely used.

I still think they are good value, and at least I'll get them before Christmas
Right after 11.11, I kind of doubt it.

Re: Another board by ICStation

Looks like the same board as the one from here posted last year.

Re: STM8 Core

I made a little breadboard pill board, more of a breakout board really, for my project with the STM8L152C6T. Feel free to do what you want with it. The traces are kind of ugly, mostly autorouter, but I was in a hurry. Also there is no regulator onboard. It was mostly copied from the STM8L discovery...

Re: Long initial MOSI bit duration using DMA

As you've noted, reality is quite different from the datasheet.

The timing is also nowhere near as critical on a number of points, see https://wp.josh.com/2014/05/13/ws2812-n ... know-them/

Re: No upload via dfu

Its definitely due to the fentanyl crackdown by Canada Post.

Re: Any support for STM8S103F3P6 boards ?

The architecture is very different, and the specs for the chip are only comparable with an ATTiny84.

I've written things using them, but only in assembler or directly in C.

Re: Another F103C8 board (but not good value)

@denis - the picture only this board unfortunately doesn't have the square indicating pin 1 on either the nrf or the esp connector track ends. oh and the oled/tft pining isn't labeled either, but it does have unpopulated eprom, spi flash and sd card track / pads srp FWIW, the NRF and ESP face outwa...

Re: F103RET6

This module is actually a daughterboard to a carrier that has ESP-01, NRF, and a few other types of ports.

Re: Improving the Wiki

OK Note. I don't think the Baite Maple Mini, is an exact clone of the original, Leaflabs, Maple Mini. I think that Baite made some changes to reduce manufacturing costs, but I don't know exactly how it differs from the original. Believe the most important difference is 2 layer pcb vs 4 in the origi...
