Use STM32 as I2C Slave with DMA
Hey guys :) I had an working system with an raspberry pi Master and an STM32F103 slave which collects data from other slaves via another I2C bus. I have done over 6000k measurements. I just added a few temperature sensors and it kills a lot of timing. To overcome this problem, I would like to use DM...

[Solved] SD.h or SDfat.h with SPI2
Hey guys :) I'm trying to use the SD.h or the SDfat.h lib with the second SPI on an STM32F103 - but I'm failing. My Idea was to remap the Pins: #include <SPI.h> void setup() { // put your setup code here, to run once: Serial.begin(9600); while(!Serial) { } SPI.setMISO(PB14); SPI.setMOSI(PB15); SPI.s...

Re: Problem with custom made Board und HiD Bootloader
ok, strange... first things first: It works right now - but I don't know why :D Following things I have done with my three Boards and it works with every Board now: programm the HID Bootloder (no programming possible, but I can read out the Serial.print stuff from programms programmed with ST Link) ...

Re: Problem with custom made Board und HiD Bootloader
I have also tried the Maple bootloader with a positive result: maple_loader v0.1 Resetting to bootloader via DTR pulse Reset via USB Serial Failed! Did you select the right serial port? Searching for DFU device [1EAF:0003]... Assuming the board is in perpetual bootloader mode and continuing to attem...

Problem with custom made Board und HiD Bootloader
Hey guys :) I have designed my own STM32F103 Board as Raspberry Pi Extension with some additional Stuff like PWM up to 120W and Pmos Switches and som Inputs for Industrial 0-10V and 0-20mA input. I also would like to use the Board with the HID bootloader from https://github.com/Serasidis/STM32_HID_B...

use a member function as wire2 callback function
Hey everybody, I have a problem in writing some Code. I'm definetly not a C++ expert - therefore it might be an easy problem for somebody who knows what he is doing. I'm would like to use three Bluepill Boards communicating with a RaspberryPi over the I2C2 Bus as Slaves on the I2C2 Bus (the standard...

Re: RTC subseconds
Might be true.
I thought about a combination of the RTC and a Millie Counter only between the logging calls.
I will try it out and if the results are more or less acceptable, I will show it here.

Re: RTC subseconds
ok, thanks!
Are there any Ideas how to build a workaround? maybe with the millis(); function?
