Posted on July 22, 2013 at 14:02Hello everybodyI have the weirdest problem on my i2c....I have some pcf8574's connected on my stm32f4Discovery and the work like a charm(thanks Clive1.....)But now i have connected some 5V relays which also work fine ...

Hi there,
I got stuck on communicating with a PCF..
I know that i have the address right, because i connected the chip to my Arduino for testing.
The program gets stuck onwhile(!I2C_CheckEven...

Hi everyone,
I'm trying to configure I2C3 on the stm32f4 discovery board but i end up
in the hard fault handler at I2C_Init.
I am doing something weird i'm sure, any ideas?
void
I2C_Co...
Posted on April 09, 2013 at 15:59Hello everyone...I have a question: I'm programming a application with a lcd-touch and i want to be ableto store a few integers to a area that keeps it's data during power off.Where do i begin, because i just have no...
Posted on November 17, 2012 at 16:54Hi,Maybe a dumb question but....Would it be possible to remap like 6 inputs of ADC1 to other pins? (stm32f4discovery)I just found some info regarding the remapping of can etc. and i couldn't find theinfo for ADC1....
Posted on July 25, 2013 at 18:31No the relays are 24v= and they switch 230v solenoidsI rather not skip the 24v= because i like to separate the 3,3/5v from the 230vthat's why i have a 24v= ''stage''So the stm32 switches on the 5v relays and the 5v sw...
Posted on July 25, 2013 at 14:44Thank you, this gives me some confidence that it is possible to use these busses and such!I will test this prototype just with the GPIO's because the rewriting will be as fast as debugging the hardware (it's just the ...
Posted on July 25, 2013 at 12:28Okay well the weird thing is that i only have i2c buswiring in a small box and the low voltagerelays are in the same box, than they go to another box with the 24v= relays that switch on the coils.These boxes are made ...
Posted on July 24, 2013 at 18:54Thank you, it's difficult to change everything now to shielded wires and such, because time is running low.In the future i will create everything shielded from the ground up!Is it only the bus that needs to be shielde...
