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 ...
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...
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 ...
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
Posted on January 06, 2013 at 23:25I wanted to use EXTI4 EXTI5 and EXTI6 with the door GPIOA but I get the an error ''EXTI5_IRQn'' is undefined ''EXTI6_IRQn'' is undefinedI have not found the list of lines Exti that I can use! you can tell me whe...
Posted on January 04, 2013 at 10:52 We have aSTM32F37x eval board for testing and I'd like to set up some code that will sample 24kHz 16-bit with the SDADC. According to documentation it should be able to sample 50 ksps if you don't use multiple...
Posted on January 08, 2013 at 06:39I am looking for SW Code of DMX512 LED light control in STM32F103. Can anyone help me how to get it? thanks #lmgtfy #dmx512
Posted on January 07, 2013 at 11:09i have designed a little pcb which uses a stm32407vet. i have had 100 boards assembled. and 96 of them work great but 4 of them the gpio on 1 pin (different pin each board) is not working) same firmware on each boa...
Posted on January 07, 2013 at 11:43Hello, I am just trying out the Stop Mode with my STM32L1 Discovery. But I think there is something I do wrong. When I use the HSI as Systemclock the consuption is higher then using the MSI. Also different MSI valu...
Posted on January 07, 2013 at 23:29Hello, strange thing happened. I setup a development environment Linux - gcc - eclipse- openocd st-Link V2 STM32F0 and F4 Dicovery boards. And I started to port a lot of my libs to STM32 Every thing runs fine unt...
