Re: stm32f407 black board with spi ili9341 ?

It should work out of the box if you copy the Adafruit_ILI9341_STM lib from F1 folder to F4 folder and configure the correct SPI port.
But it was not tested, so no 100% guarantee.

Re: STM32F103 minimal synth

Guys, does anyone know a PC software / tool which converts a WAV or MP3 file to delta-sigma format?
I would like to generate some short sound effects with the blue pill.
Or any alternative way to do it?

Welcome! To use external interrupts, see: http://docs.leaflabs.com/static.leaflabs.com/pub/leaflabs/maple-docs/0.0.12/external-interrupts.html or libmaple core reference here: https://github.com/rogerclarkmelbourne/Arduino_STM32/blob/4021c32fdb809f16a61c073d04e1d8c2c487a767/STM32F1/cores/maple/ext_i...

Re: Waveform Generator (Two DAC examples)

The code you are using is for PT8211. For TDA1543, you have to : - exchange the high and low bytes order (it requires LSB then MSB, while your code is sending MSB then LSB) - the TDA is fed with 5V, the STM32F1 is working with 3.3V - level adaptation may be necessary EDIT - the signal values may nee...

Re: Waveform Generator (Two DAC examples)

I've been trying to make a blue pill works with a TDA1543, using the code from vassilis (http://www.stm32duino.com/viewtopic.php?f=18&t=519) I cannot find any specific code under the given link. What is the scope of the presented circuit and how should it work? What kind of signals are input to BCK...

Re: CAN Bus Library for STM32F103

I'm able either to start my usual CAN script, or start USB as UART Serial port. That is a nice feature. But... Does anybody need it? I doubt. I think one uses one or the other, but I cannot imagine any application in which USB and CAN should be alternatively used. So in order to keep the original v...

Re: halo from indonesia

For output on PA9/PA10, you have to use Serial1.

Code: Select all

void setup() {
    Serial1.begin(115200);
    Serial1.print("test print donk");
}
uint32_t counter;
void loop() {
  Serial1.println(counter++);
  delay(1000);
}

Re: [libmaple] Black F407VET6

Use the brackets correctly:

Code: Select all

dataPoints[j+1] = (&ADC2)->regs->DR & ADC_DR_DATA;

Re: Power Blue Pill and Maple Mini from external 3.3 source?

I have a blue pill working 24/7 with external 3.3V supply since 6 months, with the on-board 5V->3.3V regulator.
And it still works...
