  1. Loading .bin without using Arduino IDE

    MakcYan

    Found a way that a person does not go into the details of the firmware. Arduino_STM32\tools\win In this folder I put a file “*.bin”, create a “*.bat” a file with contents: "maple_upload.bat" COM13 2 1EAF:0003 "*.bin"

  3. MPR121 i2c touch keypad with Wire library

    RogerClark

    …nd ask them about this, as I don’t have detailed knowledge of the hardware I2C on the STM32. The alternative is to try using STM’s own official Arduino core for the F103 github.com/stm32duino , and see if that supports repeated start https://github.com/stm32du…
  4. MPU-6050 (I2C) Library

    Hello…after many hours, autolevel in stm32 work right. https://www.youtube.com/watch?v=JKp9divSNO8
  5. Making examples easier to find

    … way to make the examples easy for people to find is to add a dummy library called “A_STM32_Examples” This just needs a header in it, called A_STM32_Examples.h and a subfolder called examples Then the IDE finds this “library” and puts it at the top of the exam…
  6. Maple Mini + Stable ArduinoEclipse/UBUNTU 14.04

    mrburnette

    …o jog my brain and I do not see anything with a step-by-step guide. As you are aware, STM32duino.com is geared more toward the Arduino IDE, but some of our members are technically very broad in their knowledge; hopefully you’ll get an answer soon. Regards, Ray
  7. Maple mini clone first program

    darth_llamah

    Try running StressSerialUSB example sketch (in Arduino_stm32/examples/Maple/) and/or check your code against it. Don’t worry about “error resetting after download: usb_reset: could not reset device”, this just happens.
  8. Maple mini from BAITE – the real PILL

    … inconsistent behavior is more difficult. i’d never be employed at Bletchley Park. on stm32, spi always seems to be a bit of a struggle, i2c also; at least to me, worse if doubled up( spi 1+2 or i2c 1+2.) using spi or i2c and a nano or uno, they work. why does…

  10. Messaging between multiple Maple Mini clones

    douginarug

    Hello All, I’m new to the STM32 devices and this forum. I was wondering if anyone has been working on the “maple bus” code. Does anyone have some example code or possibly a new library for this type of communication? I had a project that used two pro mini ardu…
  11. Minimum ADC reference voltage?

    RogerClark

    …for anything better, you would indeed need an op-amp. If the best we can get from the STM32f103 is 10bits, then you are reduced to about 6 bit accuracy (31 steps).. and so forth. There is an interesting article on oversampling on the STM32 series here -> ht…
  12. Multi encoder sketch with acceleration

    max_sl

    Ok. I work with Arduino and STM32 for about 3 month so could you explain these strings: if ( (gpio_read_bit(PIN_MAP[encoderpinA].gpio_device, PIN_MAP[encoderpinA].gpio_bit) ? HIGH : LOW) != A_set ) { A_set = !A_set; if ( A_set && !B_set ) { //if (milli…
  13. NUCLEO_073RZ support

    fpiSTM

    Oh nucleo 64 is not for 64 bits it’s just a form factor Nucleo 144 is not 144 bits . STM32 are 32bits and STM8 are 8 bits. STLink are connected on PA3/PA2 (Rx/Tx). PeripheralPins.c show those pins can used 2 U(S)ART: https://github.com/stm32duino/Arduino_T … i…

  17. New SdFat library (with and without DMA)

    stevestrong

    Here is an older but still working version, good for getting accommodated with the basics. There is an “issue” in the (older) SDfat lib, because if you want to go without FAT or any other file system, the sd.begin() function returns an error. You just have to …
  18. New to STM32 and projects on it

  19. New wiki

    racemaniac

    …the wiki of things you may want to use. Like for example what was asked in http://www.stm32duino.com/viewtopic.php?f=3&t=1095 It may be useful to start putting basic code samples that show how to use all the features of the stm32 .

    …speed things up, but may save some RAM There is an optimise option menu, in my Arduno-STM32 core, which would have more effect. The default optimisation is for “size” -Os but this is probably the slowest setting. Try the -O2 or -O3 settings, with or without LT…
