Re: RTC CLOCK on BLUE PILL with Four 7 segments

Yeah, there are many ways to light a 7 segments LCD and thanks for all the good advice ! Now Luckylight is on the table... LUCKYLIGHT KW4563ASA COMMON ANODE No special modification of USB library requirement just cancel the jtag function One rows of pins solder directly to the pcb DS18B20 senzor dis...

Re: RTC CLOCK on BLUE PILL with Four 7 segments

Pay atention to pins when you solder the LCD and if you want ,my friend, put a 120...220 Ohm Resistors on the dig1, dig2, dig3,dig4 pins. I also experimented with Arduino Mini in the past. Everything works ok many months for now. Why? Because is a neutral times between the spike. The next step is a ...

Re: RTC CLOCK on BLUE PILL with Four 7 segments

There is no resistors!(Of course pull-up for DS18B20 sensor must be) All pins of 7 segments LCD is solder directly on blue pill STM32... The software makes everything. Multiplexing and timer fake pwm...

Re: RTC CLOCK on BLUE PILL with Four 7 segments

Hello again... a little update with a DS18B20 and new parameter for display... TDV = 0 to 30 seconds .Time Display Value display alternately clock or temperature(-40*C , +99*C) in 1 to 30 seconds per minute The DS18B20 is have a pull-up resistor 4K7 (not critical values for short cable). http://i64....

RTC CLOCK on BLUE PILL with Four 7 segments

Hi, recently I finished the mixing ugly code for the multiplexed Four 7 Segments .Cheap and easy way to build this... Just solder directly(!oh, don't do that! :oops: ) on the STM32 Blue Pill. http://i65.tinypic.com/2u4izpe.png "Pasta ingredients and procedure:" configuration No JTAG !! is in code bu...

Re: Some pins not usable when using ST-Link ?

Hi, my reasons for canceled DFU are : - In windows 8.1 x64 DFU is not work very well, is a pain; - I want solder the 7 segments LCD directly and ugly to the BluePill pcb, see the nice foto on my desk, :); https://preview.ibb.co/c2fHFk/stm32_7_segments.jpg russian photo hosting site - running RTC fro...

Re: Working example from set internal RTC

I remove Time.h and Time.cpp from folder ...\Documents\Arduino\libraries\Time-master and the example work fine: #include <RTClock.h> #include <TimeLib.h> //this is where we will store the unix time uint32_t tt = 0; // initialise the RTC library. // NOTE: 'RTCSEL_LSE' assumes you have a 32.768Mhz cry...

Wiegand 26 and Wiegand 34 library for Arduino

Hello, hello, my friends ! How about wiegand on STM32? I work with atmel and is fine https://github.com/monkeyboard/Wiegand-Protocol-Library-for-Arduino I try to put some pins in interrupts on the code but for STM32F103RET6 not work . void WIEGAND::begin() { #ifdef digitalPinToInterrupt // newer ver...

Re: winbond SPIFlash.h define for delayMicroseconds(us)

Yes, it work! with the upper topic
Thanks again

#if defined (ARDUINO_ARCH_SAM) || defined (ARDUINO_ARCH_SAMD) || defined (ARDUINO_ARCH_ESP8266) || defined(__STM32F1__)

Now see if my project with load binary from sdcard to winbond BIOS work .On arduino pro mini time to loading was 45minutes...:)
