Re: F405 & F411 versions of the BluePill

Squonk, then what do you think, keep original connector in the position it was originally, or are you going to try that smaller one you found? I don't think this is a deal breaker for anyone, at least not for first revision testing. On a different subject, I'm going to make a comment on how I have r...

Re: First experience review of allpcb, $15 for 5 100x100mm boards, $5 for 50x50mm boards, shipped DHL

Dev, are you embedded...@...? If so I see the credit in my page, so it's still giving me credit that we can use for community projects. Or so I hope, I have not tried yet to use any of the credit that shows up as "coupon" in my page since the F4 pill board is not final yet. I'll update the first pos...

Re: F405 & F411 versions of the BluePill

Squonk, on sdcard connector, whichever works best for you in placing in the board. I think everyone agrees that the connector the other way around would be nice, but is not critical. Racemaniac, I think the shipping from China to multiple places would probably increase the cost. Where are you locate...

Since the F4 bluepill is almost ready to start prototyping, if you registered with my link in the first page, please send me a private message and let me know, to track those credits to use for F4 bluepills. I am not aware of any other community project going on yet, but if there is another and get'...

Re: F405 & F411 versions of the BluePill

Funny, if you enter Qty 60 from radio buttons, you get $19, but when you enter it in the text field and submit, you get $20 :shock: Where did you get the 64x16mm dimensions from? The actual PCB size is 53.34 mm x 22.86 mm. OK, here is the selection: allpcb_order_form.png I think it could be nice to...

Re: Need Help with EEPROM Emulation

As pointed out before, the problem is most likely that you are wiping the whole flash when uploading with St-Link. You must use a method that doesn't wipe the whole flash (you can do so if using the ST_link GUI tool, has an option to select whether you want to completely erase the mcu or only the re...

Re: [SOLVED] Enable interrupts from inside a timer interrupt

There is also the option to feed a timer from another timer. I don't remember all the details, the datasheet shows what it can do, but perhaps that can remove the need to have 2 ISRs completely and leave only 1. I think that one of the modes is to enable the second timer to count once the first time...

Re: F405 & F411 versions of the BluePill

or anyone sees an advantage on having the panel? They do not provide Vcut within a panel when the individual board is less than 80x80mm.. (do select "Panel Separating Way:") So the only option is, for example, to buy Single PCB, 60pcs 64x16mm, $19 as of today. PS: It seems they are steadily increas...

Re: F405 & F411 versions of the BluePill

It looks like the board dimensions are too small for www.allpcb.com to do V-cuts, but they accept tab routing and they propose to do it themselves for free, resulting in a total cost including 24h lead time and TNT shipping to France (3-5 days) for 40 pieces @ $20 (60 pieces are only @ $23 !?!). Un...

Re: F405 & F411 versions of the BluePill

If you can fit the SDCard pointing out, I think it will be a bit more useful if the card is plugged in something, so doesn't have to be pulled out. That said, if that's not possible, I don't think it's a major issue to go ahead with our first rev with the card in the original position. There have be...
