Posted on November 05, 2016 at 19:04 Hi I would like to use L7987LTR in a few designs. The datasheet of the IC says its able to provide 2 A current however I can only measure 0.5 A. I have tested the schematics in 3 different layouts and l...

Hey friends,
I am trying to initialize I2C to read the content of 24AA02E48TEEPROM but after initializing the I2C busy_flag stays set. the code gets stock atwhile(I2C_GetFlagStatus(I2Cx, I2C_FLAG_BUSY )); ...

Hi,
I am trying to read the content of an EEPROM,24AA02E48T, using HAL I2C library.
There is an example for this task which has been done in SPL instead of HAL and can be found athttps://github.com/Catethys...
Posted on November 13, 2016 at 09:36Hi,I found the problem while back and I thought to share it so if people have the same problem, they can use it. If you are using GPIO_Pin_8 | GPIO_Pin_9 for I2C then in void I2C_init(I2C_TypeDef* I2Cx, uint32_t s...

Posted on July 19, 2016 at 14:21Hi clive1,Thanks for your response. I know that I2C is open drain and I have a 10k pull up on SDA and SCL. if you look at my code im initializing it to GPIO_Mode_AF_OD. I just performed that test to verify that hardw...
Posted on July 19, 2016 at 04:27Hi,For testing, I changed GPIOB_Pin8 and GPIOB_Pin9 pins to push/pull mode and toggled them. They are my SCL and SDA in I2C mode. I can get state high, 3.3VDC, and low successfully by toggling the pins. In addition, f...
