Re: Setup of STM32F104CBT6 board

3K of Memory is a lot ;) I gave it a try and ended with: ************************************************************************************************** *** This sketch will update the bootloader in the Maple Mini to the STM32duino bootloader **** *** With this you can use up to 120KB of Flash a...

Re: Blue Pill with nicer silk screen PCB

nice btw, another small question on ordering these. For me starting at 3 boards, the shipping is no longer free as they switch to another shipping method. What do you guys do? just go with it, or make multiple small orders? (i've been testing out the latter, seems to work XD) You can do it pretty q...

Does it have the correct 1.5 kohm D+ pullup?

Re: Custom Board

basically if you follow the Maple Mini schematic you can't go wrong (well you can, PCBs always go wrong) to simplify things you may choose to ditch the dual power supply (the Baite clones do this) and ditch the USB reset circuitry (everything except the 1.5k pullup, the 2* 22 ohm series resistors an...

Re: "Black pill" board?

I believe I may have found the schematic for the black pill. If so it can be added to the wiki. My boards are on order, so I can't verify that this is the right drawing. The 1.5k USB resistor is shown on the schematic as R7. Schematic is here . Seems to be the correct schematic. There is a diode be...

Re: "Black pill" board?

Hello everyone, Has anyone seen/used this board before? At first glance, it looks like a "black" Blue Pill board. For port A and B, it has the same pins brought out, but for port C, only PC13, which I can only assume is for the on-board LED. It also has less gnd and 3V3 pins and no 5V and...

Re: Improving the Wiki

How bad is this problem? I was planning on using a Maple Mini to transmit ADC values via an NRF24L01+ (SPI). It is only critical to sample with ADC while accessing the SPI in the same time! In my case the ADC was triggered periodically by timer 3, while the main loop could write the already sampled...

Re: Improving the Wiki

Also. The photo you have of the Maple mini, on the main page is the original one that LeafLabs produced, but is no longer available. It would probably be better if we had a photo of the Baite Maple Mini as that's the one that is widely available and, if you buy from Baite directly, on their AliExpr...

Re: Improving the Wiki

Thanks Roger Unfortunately, it looks like the wiki software is very fussy with .svg files, and won't take ones such as mine (exported from draw.io). See this post https://github.com/mgeb/mediawiki-drawio-editor/issues/1 it doesn't look like there's much you can do about that, hopefully the developer...

Re: Improving the Wiki

Roger, would it be possible to enable .svg images in the Wiki? I'm working on some pinout diagrams and it would be nice to upload them in full quality.
