Posted on January 09, 2013 at 02:49from ST documents PDF (LED light control using DMX512 control method ), it mention the application source (IDE IAR Embedded Workbench) is available only on request and is covered by license agreement. So, Can someo...
STM32F4 Discovery FSMC problem
Posted on January 08, 2013 at 03:18I am trying to get the F4 discovery board to communicate with a FPGA board via the FSMC but I am having some problems. I have connected the data 0-15 lines, we, oe, and addr 16-23 from the discovery to my fpga. I c...
networking STM32s
Posted on January 08, 2013 at 20:31I have a question. I need to connect 2 to 6 STM32s together. I have motors I need to collectively control with a human machine interface. Each motor will be controlled by one STM32. The HMI also needs a STM32. ...
LCD_8bits
Posted on December 12, 2012 at 10:09I am trying to use an LCD HD44780 (2X40) with STM3210C-eval. I want to configure it for 8 bits mode. #re-inventing-the-wheel
STM32F207 I2C DMA and NAK
Posted on January 08, 2013 at 15:38I am using DMA to transfer data to/from an EEPROM over I2C. Most of the time this is working fine but on the odd occasion when reading from the EEPROM the I2C peripheral does not seem to be sending a NACK when the ...
STM32F4 I2C
Posted on January 04, 2013 at 07:37HiI am attempting to interface the aptina mt9d111 with the stm3240g-eval board.To initialize all the cam registers, I have to make use of I2C. As far as I know I2C sends only 8-bit data. But some of the registers a...
STM32F37x: What is ''tempo'' or probably temporization for the clocks
Posted on January 07, 2013 at 18:17Hello, rm0313 in figure 10 ''Clock tree part1'' has a ''tempo'' unit at each clock input. Beside a use of the word ''temporization'' in 7.2.11 ''Watchdog clock'', I see no more use of that word and no explication ...
STM32F3xx opamp input bias?
Posted on October 13, 2012 at 06:49Input bias current is not listed, so I don't know how to size a resistor divider for use with the STM32F3xx series. Has anybody measured it? Is it hiding in a datasheet I haven't found?Thanks!-Sasha #opamp
