KenLaszlo Fri Nov 24, 2017 2:12 pm Hi folks Roger encouraged me to make a post here, so here’s me ‘taking the plunge’. My first code-snippet / project. ..
Vassilis Fri Aug 28, 2015 5:52 pm The sketch I wrote uses the hardware SPI interface of STM32 microcontroller. You can connect a I2S DAC like PT8211. The serial ..
madias Mon Apr 27, 2015 3:51 pm easy to use sketch for setting up multiple encoders with acceleration (faster movements, more data increase). IRQ driven, HW timer ..
petertumler Thu Sep 24, 2015 10:58 am Hi, I’m trying to underclock a STM32F103 (Maple Mini) to 48MHz (for energy efficiency reasons). According to the datasheet ..
Pito Fri Jul 14, 2017 6:43 pm The old style vector graphics terminals are still in use, at least here Here is the TEK 4010/14 you may get at ebay most probably.. ..
enif Fri Aug 14, 2015 1:26 pm When trying to port my little “car blink sound booster” program to the Maple Mini, I realized that there are no tone() ..
Rick Kimball Mon Jun 15, 2015 9:20 pm I got pretty spoiled with other microcontroller architectures that allowed you to use delay_cycles to do sub microsecond delays ..
Slammer Wed Apr 13, 2016 11:58 pm I miss very much the old-school printf() function…. I am tired to write again and again Serial.print() commands to display ..
madias Tue Jul 07, 2015 3:34 pm Edit: Video is here: http://youtu.be/bv_LYtYQCmk I was fooling around with the included adafruit ili9341-STM32 library, thinking ..
Pito Fri Aug 25, 2017 8:37 am Here is an example with measuring Interrupt Latency. AttachInterrupt function used. In the code the PA14 and PA15 are used for INTR_IN ..
Rick Kimball Tue Jun 09, 2015 8:44 pm I’ve taken the gpio code I posted in another thread to the next level. This one provides PIN abstraction and some nifty ..
arpruss Sat Nov 25, 2017 8:00 pm I made some fast bitband-based gpio preprocessor macros that generate fast and small i/o code. They work only with pin numbers explicitly ..
Rintin Thu Dec 15, 2016 1:14 am Hi, I needed to detect if a button is pressed once, twice or long. For this I wrote the attached code. The used pin is configured ..
Rick Kimball Sun Jun 07, 2015 3:59 pm In another thread, I had made brief mention of using placement new to delay the constructor call of an object. However, it isn’t ..
Rintin Fri Jan 29, 2016 5:58 pm Hi, I’ve got this RF mini controller for the WS2812b. I figured out that it sends on 433Mhz. I connected one of these Rf-receivers ..
victor_pv Wed Apr 29, 2015 11:56 am Hi all, I noticed recently that even though PIN_MAP is declared as const, it is stored in RAM. As it is a constant, I don’t ..
stevestrong Sun Oct 29, 2017 9:20 am I have a project in which I need some short sound effects, without reading WAV files from SD card. To output PWM audio, current ..
dangthaison1992 Sun Nov 27, 2016 9:58 am I try the code ext interrupt pulse measurement on PA8 at STM32F103C8T6 chip. it’s ok #include "HardwareTimer.h" volatile ..
Rick Kimball Wed Dec 28, 2016 9:48 pm I came across an interesting feature of the GPIO BSRR registers. The BSRR register allows you to modify both the reset (BSRR_H) ..
