STM32F105 Dual CAN Filters

Posted on April 24, 2015 at 12:18On this processor both bxCAN cells share the filters located in CAN1. There is only a single CAN_FFA1R register whose bits are used to assign individual filters to FIFO 0 or FIFO 1. There is no bit allocating them to...

STM32F103 Clock Configuration

Posted on April 28, 2015 at 23:47Hi,I have a question concerning the clock configuration of an STM32F103RBT6. I used several STM32F4 chips before and generated the system_stm32f4xx.c file with the STM32F4 Clock Configuration Tool. It seems that ther...

SDIO + DMA -> FEIF error

Posted on April 29, 2015 at 17:05I didn't find way to avoid this error but ignoring it. I wasn't the first one of doing so. There is an example from Keil: .\Keil\ARM\Boards\Keil\MCBSTM32F400\RL\FlashFS\SD_File\SDIO_STM32F4xx.c[code]static BOOL Write...

STM32CubeMX: SDIO 4bit issue

Posted on April 15, 2015 at 17:33STM32F429 Generated Code does not initialize all pins correctly, some should be set to open drain highspeed, this has to be done manually. Without this only 1bit mode works correctly 4bit gets stuck. We use a 2GByte ...

Quadrature encoder simulation

Posted on April 28, 2015 at 16:49Hello I am using the STM32F4 interfaced with two hall effect quadrature encoders.Is there a method to generate the signals (A,B) coming from the encoder to validate my work ? because now i don't have the sensor  #...

Where is the datasheet? OR Where is my tutorial?

Posted on April 29, 2015 at 14:24I bought a discovery board with STM32F4 family processor (comes with a TFT LCD). I have my IDE working and downloaded CubeMX and generated some init code - no problem.Now, I don't know how to do anything! How do I to...
