I have an STM32F103C8T6 Blue Pill board, and I'm trying to get the RTC to function correctly when Vdd is removed. However, when I disconnect Vdd, the RTC doesn't operate as expected. Sometimes, when Vdd is supplied, the RTC starts counting from the time I disconne...
The generic BluePill board and two resistors are all you need, and a few extra cables make the install clean and reversible – you could definitely solder to the DYMO printer’s PCBs if you needed, too. Essentially, you intercept the RFID reader connections, where the BluePill acts as an...
STM32 Blue Pill Rotary Encoder One 5mm LED One 220 ohm current limiting resistor Connecting Wires Breadboard Connect the components as shown in the schematic diagram below:Connect the LED’s anode pin to PA6 through a 220 ohm resistor. The cathode pin will be grounded. ...
STM32 Blue Pill One 10k resistor One Push button FTDI programmer/ USB to TTL converter Connecting Wires Breadboard Connect the components as shown in the schematic diagram below: Connect of end of the push button with PA0 through a 10k ohm (pull-down) resistor which is grounded at the other...
To build for the Blue Pill you can select BLUEPILL_F103C8 or NUCLEO_F103RB as your target, depending on the Flash size actually available on your Blue Pill board. To reduce the size of used static RAM and Flash try to select the small library for your project rather than the standard ...
As usual made on perfboard. I make just one so I did not develop a PCB for it. For the pictures I removed the display, so you can see I did not waste the space under it, room for the battery and a lithium-ion charging module (not in the schematic)....
Schematic: Layout: Bluepill collides with mounting hole in corner Panelize Board Mounting holes for RS485 Transceiver should have been 2.54mm smaller, not bigger? Holes for TO220 should have been even bigger No coating on 5V rail to WS2812B ...
FIG. 12 is a schematic side elevation of a printed circuit board and cylinder demonstrating emitter and detector mounting; FIG. 13 shows a top plan schematic of emitters and detectors arranged about a cylinder, with numerous light path orientations shown; ...
